Description

  The present invention relates to a flexible solar cell assembly and a method for installing the flexible solar cell assembly, and more particularly to a flexible solar cell assembly that is easy to attach and detach and excellent in durability and a method for installing the same.

  Research and development of clean energy has been promoted from the viewpoints of securing energy and environmental protection, and solar cells are expected as one of clean energy sources. The solar cell is composed of a solar cell module in which a solar cell body that generates electric power using sunlight is modularized. Considering the further spread of solar cells, it is desirable that a user can easily attach and remove a large amount anywhere, not just on the roof of an existing structure. There is a background to provide a solar cell assembly installation method that is inexpensive and has a high annual power generation for the purpose of making an environmental appeal from the bottom.

  As solar cell modules, there are roughly divided flexible solar cell modules and rigid solar cell modules. A flexible solar cell is represented by the example of a thin film solar cell, and has become the mainstream of a flexible solar cell now. Thin-film solar cells are solar cells with a thin power generation layer, and range from large and thick using a glass panel to small and thin using a plastic resin film. For inorganic materials, silicon and amorphous silicon are used, and for organic materials using compounds other than silicon, there are organic thin films and dye-sensitized organic materials.

Japanese Patent No. 2698200 JP 2010-287598 A Japanese Patent No. 4325107 JP 2010-0050196 A JP 2006-339684 A Japanese Patent Laid-Open No. 08-288532 JP 11-46007 A Japanese Patent No. 3932029 JP 2004-235188 A JP 2003-074157 A

  Background Art Flexible solar cell assemblies are designed to be installed on the roof. In the case of a glass panel type solar cell, the solar cell is installed on a roof-like surface via a mount. In the case of lightweight flexible solar cells, the mainstream is the method of bolting together with steel plates on the roof-like surface, so the installation area is limited to the roof-like surface, and there is a limit to installing it with a large capacity. there were. The installation work also requires a specialist, the material costs for the frame and steel plate, etc. increased, and the installation work itself required many processes and construction periods. Once installed, there is a problem that it is difficult for the user to remove and cannot be relocated in an emergency.

  Due to the complexity of the installation work, the total price including the installation work of the solar power generation system has risen remarkably. In particular, one of the reasons why solar power generation systems in Japan are not widespread is the high initial cost. Accordingly, there is a need to provide a method for installing a flexible solar cell assembly that reduces the total cost including material costs, with the aim of simplifying the installation work, which is a cause of a large price increase, as much as possible. In particular, when the flexible solar cell assembly is installed by being bonded to a surface such as a roof, there is a high possibility that a problem of peeling occurs due to air expansion of the bonded surface at a high radiant heat. In addition, since a special contractor is required for the installation work, it is difficult for a business model such as a rental to be created because the user cannot attach or remove it. Moreover, since it was installed on the roof and cannot be seen from below, there was a problem that environmental activities could not be appealed from the installed user's standpoint.

  In the case of the background art, it is unavoidable that it is installed in a place such as a wall to make it stand out. However, from the viewpoint of the amount of power generated on one side, there is a problem that it is greatly deteriorated. It is difficult to be aware of the performance of the power generation amount in solar power generation because the solar cell module is based on the power generation amount at 20 ° C. It is known that the power generation amount of a general solar cell module deteriorates as the heat increases. In a typical crystalline silicon type glass panel, the power generation degradation in the summer installation environment is about 30%. This is because solar cell performance is regulated at 20 ° C, and the amount of power generation is uniformly proportional to the temperature coefficient, so in an actual summer installation environment, the temperature of the solar cell alone will rise significantly above 20 ° C. It is because it will be 80 degreeC or more. Even when the temperature coefficient of crystal silicon is increased by 60 ° C. with a temperature coefficient of 0.45, degradation of 27% occurs in the multiplication calculation. Even the thin film type was adhered to the steel plate or the roof in the background art, so the amount of power generation was deteriorated by the radiant heat in the same manner as the glass panel. As described above, the installation on the roof has a problem that the temperature of the flexible solar cell module rises due to the radiant heat from the surface, resulting in a significant power generation loss.

  The flexible solar cell assembly has a problem that it is difficult to stably suspend it in the space for a long period of time. The reason for this is that the flexible solar cell assembly of the background art is not durable enough to withstand long-term mechanical loads such as dead weight, wind pressure, balls and wrinkles, salt damage, etc., when suspended in space. Because.

  Patent Document 1 and Patent Document 2 propose that a net such as a net is stretched on a roof or a wall, and the four corners of a solar cell module of a glass panel that is not a film type are fixed to the net with small fixing brackets. It is a method that is fundamentally installed in parallel to the surface of the roof or wall at a short distance and is limited to an environment in which the influence of wind pressure or the like is suppressed as much as possible. Because the distance from the surface of the roof and the radiation surface of the wall is short, the heat dissipation effect is also poor. In addition, a small metal fitting that is not integrated with the heavy-weight solar cell module is partially fixed to the rope, so when the solar cell module is suspended in an empty space with this method, it is greatly shaken and integrated by the wind pressure. There is a high possibility that a small fixing bracket that has not been removed will come off. In addition, a heavy glass panel solar cell module is used, and if high weight and wind pressure are applied at the same time, the deflection of the roof surface and wall surface will not bend any further, so it will somehow be applied to the roof or wall. It is limited and holds. The condition is that the roof and wall surfaces are strong insurance. Therefore, the subject that the position to fix will be limited to a roof or a wall surface occurred.

  Patent Document 3 proposes that a flexible solar cell module is protected on a roof, a tent, or the like with a membrane structure having a back surface and a light receiving surface. It has been proposed that a film body and a net are wound around a support frame provided with a support member, and the net is hooked on the support member projection to fix the film. Such a fixing method cannot be installed in large quantities. Moreover, in the fixing method of patent document 3, the roof and the tent serve as a stopper for the deflection caused by the wind pressure, and are not installed in an installation environment other than the roof and the tent. Since it is in contact with the installation surface, it is an installation method with no heat dissipation. Further, the strength can be managed only in a small area such as a roof or a tent, and the installation environment other than the roof is not a longer distance than the roof. In addition, since the light-receiving surface protects the net, it is impossible to take measures against salt damage. Moreover, in the product example of a flexible solar cell module with a relatively small area, the holes of the eyelet are pierced at the four corners of the flexible solar cell module from the beginning, and it can be easily removed and tied to any place with a string or a binding band. Some can also be installed. However, because the local parts at the four corners of the flexible solar cell module are pulled directly by a string or a binding band, the string may unwind in a strong wind pressure environment, the binding band may break, May be destroyed, or the power generation layer may be destroyed by pulling. After all, in this case as well, there was no choice but to install it in close contact with the surface of the roof or wall that was not affected by wind pressure.

  Patent Document 4 relates to a flexible solar cell module, and it has been proposed to tie a rigid aluminum frame with a string or a binding band, or to directly bolt the rigid aluminum frame to the rigid aluminum frame. In terms of strength, it is necessary to install it in close contact with the surface of the roof or wall, and it cannot be installed in a space with very high wind pressure.

  In Patent Document 5, it is proposed that a solar cell is fixed to a rigid frame on four sides by sewing several places with a string. The flexible solar cell module is pulled strongly with a string directly, and there is a possibility that the string is unwound by wind pressure or the power generation layer of the flexible solar cell module is destroyed. For this reason, it cannot be installed in a space with high wind pressure.

  Patent Document 6 relates to a solar cell module of a rigid glass panel, which is reinforced by using two wires and tightening an open-loop hook bolted to the solar cell module with a small screw as a stopper to stop the wire. It has been proposed. Moreover, because it is a structure that attaches a hook fixed on the short side between the long side direction of the solar cell module and suspends it with a wire, the roof is managed as a stopper for the strength of installation in a small area like a roof with strong wind, It can withstand, but is not strong enough to be installed in an empty space. It is a limited example that can be applied only on the roof. Moreover, suspending the hook fixed to the short side between the long sides with the wire has a problem that the solar cell module is easily broken. As the wire tension adjustment mechanism, we are trying to adjust it with a turn buckle or a mainspring winding type roller. There was no problem. Moreover, there is a problem that the wire is pulled out by pulling just by winding like a reel of fishing gear. This is because the wire is not fixed in a closed loop with a certain high strength. Moreover, even in the case of a turnbuckle, there is a problem that one side is a closed loop and the wires are tied together, so that strength cannot be obtained. On the contrary, one side of the turnbuckle is an open loop hook, and there is a problem that the fixing is released.

  In Patent Document 7, it is proposed to install a flexible solar cell module on a membrane-like dome roof or the like with full protection. There was a process of welding in the process of installation work, and there was a problem that the installation work process increased and the installation cost increased. Moreover, this is an installation method limited to a place where there is a membrane-like roof such as a membrane-like dome roof, and it cannot be hung in a large amount in an empty space. The above is an example of installation limited to roofs and walls.

  Patent document 8 assumes the use of the flexible solar cell module of Fuji Electric Systems Co., Ltd., and proposes an example that can be installed other than the roof and the wall. In the description of Patent Document 8, it is not possible to withstand the wind pressure so that there is an instruction to remove it when strong wind comes out. This is because the flexible solar cell module is held by only two local supports per sheet. In this case, not only the guide portion is broken due to the concentration of the local tensile force due to the strong wind, but also the power generation portion layer of the delicate flexible solar cell module can be broken. Moreover, it is an open loop rail structure in which the guide mechanism is sandwiched between two wheels, and derailment may occur in practice.

  Patent Document 9 assumes the use of a flexible solar cell module manufactured by Fuji Electric Systems Co., Ltd., and proposes an example in which wires are installed on both the north and south sides of a pond other than the roof and walls. Since the number of wires installed is increased by actively installing in the north-south direction and setting the inclination angle with a complicated mechanism, there is a problem that the material cost is high. The fixture for suspending the flexible solar cell module is also completely separated into the flexible solar cell module side and the wire side, and the flexible solar cell module side has an open loop hook shape that can be easily removed. For this reason, there exists a subject that there exists a possibility that it may remove | deviate and a number of parts increases, and material cost and processing cost further increase. In addition, the wire side fixing metal fitting is short and has a local fixing portion, and the conduit also fixes the semicircular shape to the upper and lower crimping bolts. The fixing bracket on the flexible solar cell module side is also fixed to the flexible solar cell module with a local bolt. For this reason, in the case of a flexible solar cell module that does not include a metal plate, not only does the fixed part break due to local pulling force in an environment with high wind pressure, but the delicate flexible solar cell module is pulled and the power generation unit There is a problem that the destruction of the layer occurs. In addition, the fixing between the support column and the wire is unknown. Because it is a local fixing method that causes breakage of the flexible solar cell module and an open loop fixing method, it is not strong enough to be installed in a high wind pressure environment.

  Patent Document 10 proposes an example assuming a space installation other than a roof to which a film material base with a bag for inserting a flexible solar cell module into two cables or wires stretched by cable stoppers is attached. However, the manufacturing method of the cable stopper is unclear, and the detailed method of joining the membrane material mount and the cable is not clear. Also, the fixing method is not clearly described. Since the membrane material mount is attached to the cable, it may be regarded as being locally attached by a normal binding means such as a string or a binding band. There is a problem that the tilt angle of the flexible solar cell module cannot be adjusted. Note that the film material of the gantry is quite long and is not interrupted, so that it receives a considerable amount of wind pressure and requires considerable durability along with its own weight. As a countermeasure, a plurality of holes for releasing the wind pressure are made in the film material of the gantry. On the contrary, a problem arises that the film material of the gantry is torn off by the wind pressure. In addition, since the bag which puts a solar cell module in is not sealed, chemical environment resistance, such as salt damage, is not improved, and it may jump out of a bag. There are additional inventions in which a damping damper and a wind-resistant stabilizing plate are attached to the cable, but the detailed fixing method with the important cable is unclear. The common point of these background arts is that the power generation layer of the flexible solar cell module with a thin film can be detached due to local support and incomplete closed loop.

  Also, looking at the amount of power generation in the year round of annual power generation, in the case of solar cell modules installed on the roof of the background technology, it is fixed in the direction of the angle of the roof, or at an angle different from the direction of the angle of the roof Even if it changed, the inclination angle was fixed to the average around 30 degrees southward. For this reason, the inclination angle could not be adjusted according to the season. Since the solar radiation angle changes depending on the season, this power generation deterioration is a factor that cannot be overlooked, leading to a decrease in annual power generation.

  Therefore, an object of the present invention is to provide a flexible solar cell assembly and a method for installing a flexible solar cell assembly that are not limited to the roof of an existing structure but can be easily attached and removed in large quantities anywhere and have excellent durability. It is to provide.

  In order to achieve the above object, a flexible solar cell assembly according to the present invention includes a substantially rectangular flexible solar cell module having a long side and a short side, and a holding unit that hermetically holds the flexible solar cell module in a hollow state. A main body for sealing the flexible solar cell module, and a holding portion having a closed-loop conduit penetrating in the long side direction of the pair provided in the main body along the long side of the flexible solar cell module. It is characterized by that.

Moreover, the installation method of the flexible solar cell assembly according to the present invention is a substantially rectangular flexible solar cell module having a long side and a short side, and a holding unit that hermetically holds the flexible solar cell module in a hollow state, A flexible solar comprising: a main body for sealing the flexible solar cell module; and a holding unit having a closed-loop conduit penetrating in a long side direction of a pair provided in the main body along the long side of the flexible solar cell module A battery assembly installation method comprising:

[First Embodiment]
First, the flexible solar cell assembly and the installation method of the flexible solar cell assembly according to the first embodiment of the present invention will be described. FIG. 1A is a bird's-eye view showing an overall view for explaining a method of installing a flexible solar cell assembly according to an embodiment of the present invention, and FIG. 1B is an A view of FIG. It is the bird's-eye view which expanded partially centering on the part. FIG. 2A is an overhead view showing the whole for explaining another method of installing the flexible solar cell assembly according to the embodiment of the present invention, and FIG. 2B is a perspective view of FIG. It is the bird's-eye view which expanded partially centering on B part. 3 (a) is a plan view of the flexible solar cell assembly according to the first embodiment of the present invention, and FIG. 3 (b) is a side view of the long side of the flexible solar cell assembly, FIG. 3 (c). Fig. 3 is a side view of the short side of the flexible solar cell assembly, and Fig. 3 (d) is a partially enlarged view of a portion C in Fig. 3 (c).

  First, the flexible solar cell assembly according to the present embodiment will be described. As shown in FIGS. 3A to 3D, the flexible solar cell assembly according to this embodiment includes a substantially rectangular flexible solar cell module 1 having a long side and a short side, and the flexible solar cell module 1. Is a holding part 2 hermetically sealed in a hollow state, and a main body part 21 that seals the flexible solar cell module 1 and a pair of long sides provided in the main body part 21 along the long side of the flexible solar cell module 1 And a holding portion 2 having a closed-loop conduit penetrating in the direction. In the present embodiment, as an example of a closed-loop conduit penetrating in the long side direction of the pair, a pair of conduit molding portions 23 is provided.

  If it demonstrates in detail, the flexible solar cell module 1 used by this embodiment is the main body of the flexible solar cell assembly which carried out the thin sheet | seat structure which bends flexibly regardless of a manufacturer or a kind, and is called the flexible solar cell module 1 below. I will decide.

  The holding part 2 puts the flexible solar cell module 1 in a bag of a sheet having a hollow structure and hermetically protects all the surroundings. The main body part 21 sandwiched from above and below and the flexible solar cell module 1 are hermetically sealed. In this state, a welded portion 22 provided by welding the short sides of the main body portion 21 and a pair of conduit molding portions 23 are provided. The conduit molding part 23 is a mechanical component in which two or more conduit-shaped parts are integrally molded in the long side direction of the flexible solar cell module 1. The linear member 3 is passed through the conduit molding part 23.

  FIG. 11A is a plan view of the linear member 3, FIG. 11B is a side view of its long side, and FIG. 11C is a side view of its short side. 12A is a plan view of another linear member 3, FIG. 12B is a side view of the long side, and FIG. 12C is a side view of the short side. The linear member 3 is a flexible rope or wire, and it can be considered that the both ends 3a are processed into a closed loop as shown in FIG. 11, or the entire linear member 3 is processed into a closed loop as shown in FIG. It is done.

  Although the material of the linear member 3 is not ask | required, generally the rope which uses the metal wire or various fiber with high intensity | strength is common. The difference from the same flexible vertical and horizontal net is that the net has vertical and horizontal connections, so that a complete closed-loop conduit cannot be connected. There is a new value in suspending the easy-to-handle flexible straight linear member 3 through the long side conduit molding 23 of the flexible solar cell assembly. The rope may be a flat plate in a band shape. In order to reduce weight, fibers are preferable to metal, but in order to increase strength, lightweight, high-strength chemical-resistant and light-resistant maintenance-free ropes such as Dyneema are used. Is more desirable. If the wind pressure is low and the number of flexible solar cell assemblies to be suspended is small, a high-strength material such as Dyneema can be used with a thin thread such as a fishing line. The diameter of the linear member 3 is adjusted according to the requirements of material and strength. However, as the number of flexible solar cell assemblies increases, the strength of the Dyneema fishing line becomes insufficient, and a thick Dyneema rope becomes desirable. As the shape, a flat belt-like belt shape such as a belt shape can be used in addition to a normal core-shaped rope. Further, a chain can be used as the linear member 3 regardless of the material. The chain is generally made of metal or plastic, but the strength of the metal chain is preferable because plastic is weak. However, since the metal chain is not desirable in terms of weight, it is desirable to apply it under conditions when the number of flexible solar cell assemblies to be suspended is small and the weight is light. In addition, when the connection with the installation fixing | fixed part 4 mentioned later is considered, the linear member 3 without a terminal process can also be used.

  As a method of processing both ends of the linear member 3 in a loop shape as shown in FIG. 11, there are eye processing and compression stop processing. Eye processing is also called ice price (knitting and insertion) processing, and is a processing in which the strands are knitted together in a loop shape with high strength in order to suspend an object by dividing the strands in half. In addition, the compression stop process which folds an edge part, makes a loop shape, winds a compression metal fitting along a main body, and compresses is also applicable. The compression stop process is also called a lock process or a clamp process. The compression fitting is usually an aluminum clamp tube, which is passed through a wire or a rope first, folded over at the end, put two in the clamp tube, and crushed with pliers or a hammer to crimp.

  The strong one made by the manufacturer increases the strength by compressing the clamp tube with a dedicated press. There is an advantage that the length can be adjusted at the place of installation to perform compression stop processing, but the strength tends to be lower than that of eye processing. Usually, use eye processing with high strength at the designed length. Wires, ropes, and belts with eye-finished ends are also called sling wires, sling ropes, and sling belts, respectively. The processing method is stipulated in Article 219 of the crane safety regulations and Article 475 of the occupational safety and health regulations for slinging ropes. By convention, there are twelve or more terminal mustaches in the sling rope. However, if strength is not required, the number of braids may be reduced to reduce terminal whiskers. Additional serving may be added to increase the strength of the wire or rope that is eye processed at both ends. The serving process is a process that further increases the strength by adding a wire or a rope. In addition, in order to increase the strength, a simple reinforcing metal fitting may be put in the eye portion.

  A wire or rope that is firmly crimped by a rotary swaging machine can be used with a metal fitting called an eye terminal with a clamp tube at the end instead of eye processing, but the strength is weakened because of crimping. From the viewpoint of strength, there is also a method in which an alloy or resin such as baby metal (white metal) or zinc is poured into the cable side of the eye terminal and welded without crimping the eye terminal. For permanent ones it is common to use zinc. In addition, a thick eye terminal that is welded and has high strength is also called a wire socket. Wire sockets are defined by Japanese Industrial Standards (JIS). This terminal processing is also called socket processing, and is the most reliable and permanent long-term durability method for fixing wires. The wire socket includes a closed type (C type) wire socket and a bolted open type (O type) wire socket. Even a bolted open wire socket is strong, so there is no problem.

  The linear member 3 is, as a general rule, a flexible rope or wire, but it can also have a shape in which a closed loop ring structure is integrated at both ends of a solid rod-like shape such as a basket. However, when installed at a long distance, the solid rod-shaped object is too long and difficult to handle in terms of transportation and installation, so use is limited to an exceptionally short distance. This is an exceptional case only showing the possibility. In principle, an easy-to-handle material such as a wire or rope is adopted as the linear member 3.

  The linear member 3 processed as a whole in a closed loop shape as shown in FIG. 12 is a long splice process in which a single long rope is knitted into a ring shape, or a gramet in which a single long strand is continuously knitted for 7 or more turns. It can be obtained by forming a long ring by processing or by compressing a long wire. Grammet processing is preferable for strength. Grammet processing is also called this endless processing. These wires and ropes are available from specialized manufacturers. The linear member 3 is manufactured after the length is determined in advance so as to match the distance between the installation fixing portions 4.

  Next, a method for manufacturing such a flexible solar cell assembly will be described. In these embodiments, the shape of the configuration and the integral molding are important, and the material itself and the manufacturing method are not considered, so the manufacturing method using a representative material will be described. The material and manufacturing method are selected in relation to the weight and strength, but this embodiment gives priority to selecting a lightweight and strong material and manufacturing method.

  As a typical example of the flexible solar cell module 1, a thin-film solar cell module is a solar cell module in which a power generation layer is thin and has a thickness using a hard glass panel as a base material of the power generation layer. There are a wide range of thin films using flexible plastic resin films and flexible glass. Thin film solar cell modules using silicon or amorphous silicon exist for inorganic power generation materials, and organic thin films and dye-sensitized organic materials are used for organic materials using compounds other than silicon. There are various types of organic thin-film solar cell modules and dye-sensitized solar cell modules. Compared to the solar cell module of the background art, the power generation layer is about 1 / 100th thin. Accordingly, in the case of the flexible solar cell module 1, the thin film of the power generation layer is easily peeled off by a mechanical load such as excessive tension.

  This embodiment is specialized in the flexible solar cell module 1 that effectively uses the characteristics of the lightweight and thin film type flexible solar cell module 1 as the flexible solar cell module 1. In this embodiment, the rigid glass panel type solar cell module is drastically heavy, so it cannot withstand the weight and wind pressure, and is too thick in shape. However, in the present embodiment, a thin glass panel having a flexible property similar to the plastic resin film similar to the film type is regarded as a kind of the flexible solar cell module 1 and is included in the scope of the present embodiment. . That is, as the definition of the flexible solar cell module 1, any flexible thin sheet-like solar cell module is included. In this embodiment, the flexible solar cell module 1 is protected from its own weight, wind pressure, baseball ball, wrinkles, salt damage, and the like by adding mechanical integral molding of the conduit molding part 23 to the flexible solar cell module 1. Any flexible solar cell module 1 can be used regardless of the manufacturer or method. A flexible solar cell module 1 that is lighter and thinner is desirable because it is suspended in the space.

  Those that are too thin and insufficient in strength can be reinforced by the thickness of the conduit molding part 23. Typical examples of the thin flexible solar cell module 1 that is desirable for application include the FWAVE series manufactured by Fuji Electric Systems of Japan and the Uni-Solar series manufactured by UnitedSolar of the United States. Since the former is delicate and fragile, the latter has a very contrasting property that it is strong and difficult to break. Therefore, typical embodiments can be covered by covering embodiments that can handle both. However, the delicate and fragile type is in principle as the flexible solar cell module 1, and the strong and less fragile type is an exceptional type. Therefore, an embodiment will be specifically described as to an integral molding method with the conduit molding part 23 of this typical flexible solar cell module 1. The present embodiment is intended to devise a mechanism that remarkably enhances all mechanical and chemical protections for the purpose of environmental conditions such as bridging installed in spaces other than roofs and walls. Under such conditions, unlike installation where the roof or wall is floated at a short distance, even if wind pressure is applied, further deflection of the roof or wall will not stop. Become.

  Further, as conditions other than wind pressure, it is necessary to devise protection from solid objects such as baseballs and baskets. Chemically, it is necessary to devise countermeasures against salt damage when it is installed near the coast. Fuji Electric Systems' FWAVE series of flexible solar cell modules have a structure in which the net flexible solar cell body of a thin printed circuit board is sandwiched from both sides by a thin plastic ethylene / tetrafluoroethylene copolymer (ETFE) sheet. It has become. This module is light and thin. This is an advantage of reducing the load load, but conversely because it is light and thin, when the module is subjected to wind pressure directly and the central part of the module is pushed, the module is moved in the direction of the short side of the module by the suspending force of the linear member 3. There is a risk that the thin film of the power generation section may be peeled off from the electrode and destroyed by being pulled directly. As an example of a flexible solar cell module, it is an example with typical low intensity | strength.

  In the present embodiment, the module is configured so that the wind pressure is not directly applied to the module, and further, the suspension force of the linear member 3 does not directly pull the module. In this flexible solar cell assembly, two or more conduits are integrally molded in the long side direction of the flexible solar cell assembly, and the entire flexible solar cell module 1 is hermetically protected by a hollow structure. As this embodiment, as shown in FIG. 3, a mechanism that puts the entire flexible solar cell module 1 in a bag of a sheet of the main body portion 21 having a hollow structure and completely seals the entire periphery is effective. As a condition of the conduit, it is assumed that the conduit is a completely closed loop conduit, a long conduit in the long side direction, and a rigid integrated structure having no moving parts. Structures that can be derailed, such as rails, are not considered conduits.

  By completely sealing, it is possible to simultaneously protect against solids such as baseballs and bags other than wind pressure and chemically protect against salt damage. In this case, after sealing the flexible solar cell module 1, the periphery of the remaining short side of the sheet of the main body portion 21 is welded, so that the entire flexible solar cell module 1 is not welded to the sheet of the main body portion 21. . That is, the entire flexible solar cell module 1 is not fixed only by the force sandwiched from above and below by being hollow. With such a mechanism, no matter what force is applied, a tensile force is directly applied to the sheet of the main body 21, and the flexible solar cell module 1 is not directly applied with a tensile force. This is because even a part of the flexible solar cell module 1 is not bonded. When the wind pressure is applied, the sheet of the main body 21 is first bent directly, and the flexible solar cell module 1 is only bent indirectly. Since the flexible solar cell module 1 is flexible enough to be wound up like a wind-up type projector screen, there is no risk that the thin film of the power generation unit is destroyed only by bending.

  In addition, a major point of the present embodiment is that the sheet of the main body portion 21 is not pulled locally. Specifically, as shown in FIG. 2, the entire long conduit in the long side direction is hung by supporting a long line. Here, since the linear member 3 and the conduit are only in contact with the long side for a long time, they are pulled in the short side direction when bent by the wind pressure, but no tensile force is applied to the conduit itself in the long side direction. As a result, since the wind pressure force is distributed over the entire long side, the pulling force in the short side direction is averagely dispersed in the long side direction, and the conduit molding part 23 may be directly destroyed by the wind pressure. Is significantly reduced. Moreover, as a condition of the structure of the conduit | pipe of the conduit | pipe shaping | molding part 23 of this embodiment, it is a perfect closed loop conduit | pipe by integral molding. Even a structure that has a structure like a U-shaped rail or a part that is crimped with a metal fitting that is open to the U-shaped part is not considered a conduit because its strength is insufficient due to its own weight plus wind pressure.

  In addition, it is novel not only to have a simple and hermetically sealed protective structure, but also to integrally form and combine the conduits on which the horizontal straight linear members 3 pass. The effect of having both full protection and conduits is high. As the material for the conduit molding part 23, the flexible solar cell module 1 is entirely wrapped in a hollow structure. It is desirable to mold with the ETFE sheet of the same material that has high environmental resistance. The thickness of the sheet of the main body 21 is adjusted according to the requirements of the material and strength. Since the whole surface hollow integral molding is the point of this embodiment, a plastic resin sheet that can be integrally molded by welding is used in principle. Also, other types of thin plastic resin sheets can be applied, but engineering plastics having a high melting point and high environmental resistance are also desirable, other than ETFE sheets.

  Polyvinyl fluoride (PVF), polyethylene terephthalate (PET), ethylene tetrafluoride-perfluoroalkyl vinyl ether copolymer (PFA), polyvinylidene fluoride (PVDF), ethylene trifluoride chloride (PCTFE), polymethyl methacrylate ( PMMA), ethylene tetrafluoride / hexafluoropropylene copolymer (FEP), ethylene / polytrifluoroethylene chloride copolymer (ECTFE), and the like.

  As shown in FIG. 3 of the first embodiment, the detailed detailed mechanism is that the flexible solar cell module 1 is entirely composed of a thin belt-shaped hollow structure conduit molding portion 23 in which two or more conduits are integrated. In between. And the area | region of the plastic resin of the diagonal lattice of FIG. 3 of the short side of the conduit | pipe molding part 23 one size larger than the flexible solar cell module 1 like FIG. 3 is welded up and down and sealed. Here, it is important that the flexible solar cell module 1 is not welded at all. This is because the wind pressure force is conducted to the flexible solar cell module 1 if it is welded. As shown in FIG. 3, the flexible solar cell module 1 does not come off because the four sides are integrally molded and surrounded by a hollow structure. In the case of a plastic resin material, the plastic resin in the shape of a conduit is molded in advance as a conduit molding portion 23 by a general plastic molding method as shown in FIG. 3 of the first embodiment of the flexible solar cell assembly. This is a standard method suitable for mass production.

  As shown in FIG. 3, the conduit molding part 23 has an integrally molded structure including a space of a thin hollow structure that seals the flexible solar cell module 1 and a space of two or more conduits. In FIG. 3, the hole of the conduit is drawn as a large perfect circle for convenience of explanation, but it does not matter in shape or size, whether it is an ellipse or a polygon. At least the shape and size of the conduit that passes through both ends of the linear member 3 to be used may be used. Although not shown in the figure because the figure is complicated, this conduit can also serve as a conduit for passing the electric wire of the flexible solar cell assembly, and therefore has a large size. In this case, it is desirable to balance the positive and negative wires on both sides. When the conduit molding part 23 and the flexible solar cell module 1 are integrally molded, the joint area around the conduit molding part 23 and the thickness of the conduit molding part 23 are determined according to the load resistance, wind pressure load and baseball ball required by the system. It is adjusted by impact loads such as In the case of the flexible solar cell module 1, the integral molding method is to completely integrate the ETFEs of fluororesins by welding the entire peripheral surface from the viewpoint of strength. For example, the welding is performed by a heating / cooling cycle using a fluororesin sheet welding machine manufactured by Shimakura Kogyo. If strength is not required, partial welding may be performed at intervals, but since the point of this embodiment is hollow sealing, in principle, the entire welding is performed to completely seal. Therefore, it becomes a completely waterproof structure.

  The stopper 31 used for installation of the flexible solar cell assembly will be described. 13A is a plan view showing a state in which the stopper 31 is attached to the linear member 3 in FIG. 11, and FIG. 13B is a cross-sectional view taken along the line AA in FIG. FIG. 13C is a cross-sectional view taken along line BB in FIG.

  As shown in FIG. 13, the stoppers 31 are attached to the linear members 3 at both ends in the long side direction of the conduit molding part 23 so that the conduit molding part 23 of the flexible solar cell assembly does not come off from the linear member 3. It is a construction part. The stopper 31 has two plate-like metal fittings 310 that sandwich the linear member 3 from above and below longer than the diameter of the conduit molding part 23, and a fixing member that fixes the two plate-like metal fittings 310 with the linear member 3 interposed therebetween. 311. The fixing member 311 includes a pair of bolts and nuts. The linear member 3 is fixed with pressure by tightening with bolts and nuts.

  As a result, the conduit molding portion 23 of the flexible solar cell assembly does not come off even if the conduit molding portion 23 is vertically hung from the linear member 3 and hung. The stoppers 31 are fixed to the linear members 3 before and after each of the conduit molding portions 23 of the flexible solar cell assembly. The structure of the stopper 31 is such that the linear member 3 is sandwiched from above and below by two plate-shaped metal fittings longer than the diameter of the conduit, and is tightened with bolts 44 and nuts 45 to fix the linear member 3 with pressure. The two plate-shaped metal fittings 310 longer than the diameter of the conduit molding part 23 are formed by casting a mold having a concave groove at the center according to the diameter of the linear member 3. The linear member 3 is fixed to the stopper 31 by sandwiching the path through which the linear member 3 passes between the two plate-shaped metal fittings 310 and tightening them with bolts and nuts. Even if the linear member 3 is vertical, the stopper 31 stops at the conduit entrance of the conduit molding portion 23 and has a strength to be supported as long as the weight of the flexible solar cell assembly is light.

  In addition, also when attaching the stopper 31 to the linear member 3 shown in FIG. 12 whose ring length is a ring shape, the stopper 31 is similarly attached to the linear members 3 before and after each of the conduit molding portions 23 of the flexible solar cell assembly. Fix it. In this case, although not shown, the stopper 31 is preferably attached only to the linear member 3 on one side of the ring shape. This is because if the stoppers 31 are attached to the linear members 3 on both sides, the two wires may not be evenly tensioned. When the tension becomes uneven, the stopper 31 is easily detached. Therefore, the stopper 31 is attached only to the linear member 3 on one side.

  In the present embodiment, the flexible solar cell assembly between the opposing fixed installation parts 4 is fixed to the conduit molding part 23 of the flexible solar cell assembly by the stopper 31 through the linear member 3 and then bridged from the opposite bank to the other opposite bank. It can be bridged without using large tools such as cranes in the process of installing in a high space without anything other than the roof and walls. The detailed procedure for this bridging will be described below. First, the linear members 3 are all passed through the conduit molding portions 23 of the plurality of flexible solar cell assemblies corresponding to the bridge distance. Thereafter, as shown in FIG. 2, stoppers 31 are attached to the linear members 3 on both sides of each of the conduit molding portions 23 of the flexible solar cell assembly. One end of the linear member 3 is connected to the fixed installation part 4 at the installation location, and the other linear member 3 is slowly lowered from the shore to the ground. At this time, each of the flexible solar cell assemblies is fixed to the linear member 3 by the support of the stopper 31 of the linear member 3 and does not come off the linear member 3. An end portion of another linear member 3 is temporarily connected to the other fixed installation portion 4 on the opposite bank, and a removable connector 471 such as a carabiner shown in FIG. 17 is connected to the other end portion. Connect and lower to the ground. This is used as a bridging tool. The detachable coupler 471 attached to the one linear member 3 is temporarily connected to two or more ends of the linear member 3 which has been first lowered. It returns to the fixed installation part 4 of an opposite bank, and the ground side of the linear member 3 temporarily connected is pulled up from the ground. If the end of the pulled-up linear member 3 is connected to the fixed installation part 4 on the opposite bank, the bridge from the bank to the opposite bank can be easily and reliably performed in this way. Since only the detachable coupler 471 and the linear member 3 need only be used as a bridging tool, the user does not need to use a large tool such as a crane to lift. The stopper 31 is to prevent the flexible solar cell assembly integrally molded with the conduit molding part 23 from falling off the linear member 3.

  As shown in FIGS. 2 (a) and 2 (b), by attaching a stopper 31 to the linear member 3, even if the linear member 3 is tilted during installation, the stopper 31 remains in the flexible solar cell assembly line. Since the sliding of the shaped member 3 in the longitudinal direction can be prevented, the installation can proceed smoothly. Moreover, in the flexible solar cell assembly in which the installation is completed, the stopper 31 regulates the movement of the linear member 3 of the flexible solar cell assembly in the longitudinal direction, so that the contact between adjacent flexible solar cell assemblies or the flexible solar cell Assembly movement is prevented.

FIG. 20C is another side view of the installation fixing portion 4. FIG. 21A is a side view of an installation fixing unit 4 of the seventh example used for installation of the flexible solar cell assembly according to the embodiment of the present invention. FIG. FIG. 21C is another side view of the installation fixing portion 4.

  As shown in FIG. 14, the fixed installation part 4 of the first embodiment includes an anchor bolt 41, a support foundation 42, a multistage ladder-like metal fitting 431, a bolt 44, a nut 45, and a fixing metal fitting 46. Yes.

  The anchor bolt 41 is a construction part that becomes a pillar of the installation fixing portion 4. The support foundation 42 is a construction part that becomes the foundation of the installation fixing part 4 made of concrete, mortar, or the like. The step-movable multi-stage ladder-like metal fitting 431 is a construction part of the installation fixing portion 4 that is a metal fitting capable of forming a multi-stage ladder step for attaching a closed loop portion at the end of the linear member 3. The bolt 44 is a construction part of the installation fixing portion 4 that is a bolt that is inserted as a step of a ladder into the multi-stage ladder-like metal fitting 431 that can be moved stepwise or is fixed to the fixing metal fitting 46. The nut 45 is a construction part of the installation fixing portion 4 that is a nut that is inserted into the shaft of the anchor bolt 41 or the bolt 44 and tightened. The fixing metal fitting 46 is a construction part of the installation fixing portion 4 that is a metal fitting for fixing the rotating multi-stage ladder-like metal fitting 431 that can be moved stepwise.

  The conditions of the installation fixing part 4 will be described. First, the position of the installation fixing unit 4 is a place where sunlight can be inserted as much as possible while facing each other, and is preferably as low as possible so as not to be affected by the wind pressure. However, even if it is said that it is low, it is not a low position where radiant heat of sunlight is generated, and it is sufficient if it is high enough to have a heat dissipation effect. Moreover, as the minimum condition of the shape of the installation fixing | fixed part 4, the linear member 3 is a linear fixed object which can be bound with a human hand. The material is not limited, but a metal with high strength is desirable in terms of strength. The installation fixing part 4 may be replaced with an existing linear fixed object as much as possible. This is because installation materials and construction costs can be reduced. Therefore, priority is given to substituting as much as possible the existing handrails on the veranda, clothes pillars, etc. as close as possible, rather than high places such as the roof. As a minimum condition for the shape of the installation fixing portion 4 for a new installation, the anchor bolt 41 is a representative inexpensive linear fixed object having high strength. However, when the linear thing like the anchor bolt 41 passes through the closed loop part of the end part of the linear member 3, the closed loop part of the linear member 3 may come off to the upper part of the bolt. For this reason, as the installation fixing | fixed part 4, it is good to provide the strong coupler which can be removed and is convenient for removal.

  A structure in which the inclination angle of the flexible solar cell assembly can be changed by changing the left and right heights is provided. A column having a plurality of holes is attached to the column base 42 of the installation fixing unit 4, and a detachable coupler is attached to the plurality of holes. Thereby, the inclination | tilt angle of the short side direction of a flexible solar cell assembly can be adjusted. Although not shown in the drawings, the height of the connection position of the installation fixing portion 4 can be reduced by attaching a removable coupler such as a carabiner to a column having holes with different heights at least as the shape of the installation fixing portion 4. You can adjust it. Thereby, the attachment angle of the linear member 3 can be changed on the left and right sides, so that the inclination angle in the short side direction of the flexible solar cell assembly can be adjusted. As an example of a column having holes with different heights, a plurality of holes may be drilled in the anchor bolt 41, or a column having a plurality of holes may be manufactured by casting. The column shape does not have to be a cylinder, and may be a polygonal column or a plate-shaped bracket as long as it is columnar. This pillar is inclined inward, and concrete and mortar are poured and hardened, and the structure is fixed by a column base 42 having a cubic shape. The reason for the inclination is that the higher the position of the flexible solar cell assembly is, the higher the inner position is.

  As shown in FIG. 14 (a), a multi-stage ladder-like metal fitting 431 that can be moved stepwise is attached to the column base 42 of the installation fixing portion 4, and the multi-stage ladder-like metal fitting 431 that can be moved stepwise can be removed at different heights. Install the bolt 44. Thereby, the inclination | tilt angle of the short side direction of a flexible solar cell assembly can be adjusted. The height of the step of the ladder is adjusted by inserting / removing bolts 44 into / from the plurality of bolt holes in the height direction of the multi-stage ladder-like metal fitting 431 of the installation fixing portion 4 shown in FIG. Thereby, the inclination | tilt angle of a flexible solar cell assembly is changed. In the case of adjusting the inclination, the effect of adjusting the inclination angle is maximized by making the facing direction of the installation fixing portion 4, that is, the direction parallel to the linear member 3 strictly the east-west direction.

  15A is a front view when the inclination angle of the installation fixing portion 4 of the first embodiment is increased, and FIG. 15B is a front view when the inclination angle of the installation fixing portion 4 is reduced. is there. The change of the inclination angle of the installation fixing part 4 will be described. The inclination angle of the flexible solar cell assembly can be changed by adjusting the height of the ladder of the multi-stage ladder-like metal fitting 431 into which the bolt 44 can be inserted.

  As for the base structure of the installation fixing part 4, a multi-stage ladder-like metal fitting 431 that can be moved through the anchor bolt 41 is set up like concrete installation work such as a handrail, and concrete and mortar are poured and hardened. An example is a structure in which the column base 42 is fixed in a cubic shape. FIG. 14 shows an example in which the anchor bolt 41 and a multi-stage ladder-like metal fitting 431 that can be moved stepwise are combined and fixed to the support foundation 42. The bottom of the multi-stage ladder-like metal fitting 431 that can be moved step by step without using the anchor bolt 41 may be extended like the anchor bolt 41, fixed by the column base 42, and fixed. The same applies to the installation fixing unit 4 described below.

  In the case of the installation fixing part 4 of FIG. 14, the inclination angle of the flexible solar cell assembly is adjusted in a stepwise discontinuous manner, and therefore fine adjustment cannot be made only by rough adjustment of the inclination angle. In the installation fixing part 4 of the second embodiment shown in FIG. 16, a fixing metal fitting 46 is attached to the column base 42 and fixed with bolts 44 and nuts 45 so that a multistage ladder-like metal fitting 431 that can be moved stepwise is rotated. It is attached to the metal fitting 46. Thereby, the inclination | tilt angle of the short side direction of a flexible solar cell assembly can be adjusted. The installation fixing unit 4 of FIG. 16 includes a mechanism for rotating a multi-stage ladder-like metal fitting 431 that can be moved stepwise. Thereby, fine adjustment of the inclination angle can be performed. The entire mechanism has a structure in which the left and right installation fixing portions 4 are integrated. In order to increase the strength by combining the weights of the left and right, it is possible to cope with the problem by using parts with thicker parts. First, the fixing metal fitting 46 is passed through the shaft of the anchor bolt 41 and fixed to the support base 42. After fixing, the multi-stage ladder-like metal fitting 431 that can be stepped into the bolt hole of the fixing metal fitting 46 is fixed with the bolt 44 and the nut 45. . Bolts 44 are inserted into a multi-stage ladder-like metal fitting 431 that can be moved stepwise in order to connect the closed loop portion at the end of the linear member 3 to the left and right, and fixed with a nut 45. The bolt 44 may be fixed with a pin, which is advantageous in that it can be easily fixed without taking time. To finely adjust the inclination angle of the flexible solar cell assembly, the nut 45 of the central bolt 44 is loosened to rotate the multi-stage ladder-shaped metal fitting 431 that can be moved stepwise, and the nut 45 is tightened and fixed at a desired inclination angle.

  As an example, it is desirable to engrave the scale of the line that coincides with the upper side of the multi-stage ladder-shaped metal fitting 431 that can be moved stepwise around the bolt 44 of the fixing metal 46 because it becomes a guide for the adjustment angle. As for the scale, it is only necessary to calculate in advance the optimum inclination angle for each inclination angle adjustment period of the year at a minimum and to put a plurality of scales. Using a protractor or the like, the optimum inclination angle for each inclination angle adjustment period for the year is imprinted while measuring the angle of the upper side of the multistage ladder-like metal fitting 431 that can be moved stepwise. If each inclination angle adjustment time is fixed, it may be stamped in advance when the fixing metal fitting 46 is manufactured, not at the time of installation.

  In the installation fixing part 4 of the third embodiment shown in FIG. 17, as a structure in which the inclination angle can be changed, a multi-stage ladder-like metal fitting 432 is attached to the column base 42 of the installation fixing part 4 so In addition, a detachable coupler 471 is attached. The multi-stage ladder-like metal fitting 432 is a construction part of the installation fixing portion 4 which is a metal fitting in which a multi-stage ladder stage is formed for attachment via a connector 471 capable of removing the closed loop portion at the end of the linear member 3. It is. The detachable coupler 471 is a construction part of the installation fixing part 4 that becomes a coupler such as a carabiner that can detachably connect the closed loop part at the end of the linear member 3. Thereby, the inclination | tilt angle of the short side direction of a flexible solar cell assembly can be adjusted. In the installation fixing part 4 of FIG. 17, the lower part is fixed with an anchor bolt 41 in a multi-stage ladder-like metal fitting 431 that can be moved stepwise so that the closed loop part at the end of the linear member 3 is attached. A detachable coupler 471 such as a carabiner is structured to be detachable depending on the height.

  The difference between the installation fixing part 4 in FIG. 14 and the installation fixing part 4 in FIG. 17 is that the ladder part can be inserted or removed, or the ladder part is fixed and a removable coupler 471 such as a carabiner is provided. The difference is whether or not it can be coupled to the closed loop portion at the end of the linear member 3. The holes of the multi-stage ladder-shaped metal fitting 431 that can be moved stepwise are holes through which the bolts 44 for fixing the linear member 3 are passed. By adjusting the mounting height of the holes, the left and right heights of the linear member 3 can be adjusted. It becomes possible to do. As a result, the inclination angle of the flexible solar cell assembly integrated with the conduit molding part 23 can be adjusted. The holes of the multi-stage ladder-like metal fitting 431 that can be moved stepwise are fixed with bolts 44 and nuts 45. Although it takes time to turn the screw, it is surely fixed. The bolt 44 may be fixed with a pin, which is advantageous in that it can be easily fixed without taking time.

  In the installation fixing portion 4 of the fourth embodiment shown in FIG. 18, as a structure in which the inclination angle can be changed, two nuts 45, a non-removable coupler 472 and a removable coupler 471 are attached to the shaft. The anchor bolt 41 is attached to adjust the two heights of the nut 45. The detachable connector 471 is a construction part of the installation fixing portion 4 that becomes a connector such as a carabiner that can detachably connect the non-removable connector 472 and the closed loop portion at the end of the linear member 3. The non-removable coupler 472 is a construction part of the installation fixing part 4 that becomes a coupler in which the installation fixing part 4 such as a shackle inserted into the shaft of the anchor bolt 41 cannot be removed. The inclination angle in the short side direction of the flexible solar cell assembly can be adjusted by directly adjusting the height of the coupler that cannot be removed.

  18, two anchors 45 and a non-removable connector 472 such as a U-shaped shackle are passed through the shaft of the anchor bolt 41 in advance to fix the anchor bolt 41 to the column base 42. Yes. As the non-removable coupler 472, a shackle having a high strength is typical, but a bilateral ring-shaped traction device having a certain level of strength that fits in the shaft of the anchor is applicable. For example, the position may be adjusted by passing a short-end eye-worked wire or an eye-worked portion of a rope that has a shaft diameter of the anchor bolt 41 that is passed through the shaft of the anchor bolt 41 and above and below the nut 45. The position may be adjusted by passing the swivel into which the shaft diameter of the anchor bolt 41 barely passes through the shaft of the anchor bolt 41 and sandwiching the nut 45 above and below the nut 45. A swivel is a towing device with a circular ring that rotates on both sides of a barrel. Further, the position may be adjusted by inserting a thick plate having two holes that match the diameter of the anchor bolt 41 through the shaft of the anchor bolt 41 and sandwiching the nut 45 above and below. In this case, the hole that does not pass through the anchor bolt 41 is a large hole through which the removable connecting portion 471 such as a carabiner passes. The non-removable coupler 472 can take various forms as described above. In the installation fixing portion 4 of the fourth embodiment of FIG. 18, when attaching the non-removable coupler 472 such as a shackle to the anchor bolt 41, two nuts 45 are put on both sides of the shackle to adjust the height position of the shackle. Adjustment is possible by rotating the nut 45 screw. The inclination of the flexible solar cell assembly can be adjusted by changing the height of the left and right installation fixing portions 4. Here, the lowermost nut 45 in FIG. 18 is a nut for reinforcing the strength of the anchor bolt 41, and is different in use from the nut for adjusting the height, and need not be particularly strong. Further, in order to make the closed loop portion at the end of the linear member 3 detachable, an additional connector 471 such as a carabiner is attached to the shackle.

  Examples of the detachable coupler 471 include a double hook or a snap hook with a snap stopper and a turn buckle other than a carabiner. In the case of a turnbuckle, the length can be adjusted by adjusting the screw by attaching it to only one side of the installation fixing portion 4 facing. The tension of the linear member 3 can be adjusted optimally. In the case of a turnbuckle, a hook type with snaps that prevent both ends from coming off or a jaw bolt type that can be removed by inserting a jaw bolt is desirable. The length of the linear member 3 is accurately determined including the length when these removable connectors 471 are used. Moreover, as the installation fixing | fixed part 4, there exists the method of adjusting the tension | tensile_strength of the linear member 3 with the turnbuckle on one side. In addition, a structure in which a closed loop portion of the linear member 3 is hooked by a winch in which two or four points are fixed by an anchor bolt 41 on one side and fixed by a self-locking mechanism of a winding winch may be used. A winch is a winder having a gear on a rotating drum. It is sufficient to turn the gear manually. Since the tension of the linear member 3 can be adjusted, the tension of the linear member 3 is increased, and the vertical braking force of the linear member 3 due to the wind pressure is increased, so that the vertical braking force to the flexible solar cell assembly is increased. Thereby, the deformation | transformation of the flexible solar cell assembly by a wind pressure decreases.

  The installation fixing portion 4 of the fifth embodiment of FIG. 19 has a structure similar to a winch and can adjust the length of the linear member 3 at a low cost. As the winding mechanism, the linear member 3 is first wound around the bolt 44 having a height required by the multi-stage ladder-shaped metal fitting 431 that can be moved stepwise, and then the end of the linear member 3 is wound around the other bolt 44. The closed loop portion is inserted and fixed to the installation fixing portion 4. By winding the linear member 3 around the first bolt 44 many times and finally fixing with the remaining bolts 44, the linear member 3 can be brought to an optimum tension.

  The installation fixing part 4 of the sixth embodiment of FIG. 20 first winds the linear member 3 around the bolt 44 of the multi-stage ladder-like metal fitting 431 at a position suitable for the width of the short side of the flexible solar cell assembly. After that, the closed loop portion at the end of the linear member 3 is inserted into another bolt 44 and fixed to the installation fixing portion 4. In FIG. 20, for the sake of explanation, the linear member 3 is drawn so as to be considerably thicker than the actual one, and is drawn so as to be wound around the first bolt 44 only once. It is possible to wind it around the bolt 44. By winding the linear member 3 around the first bolt 44 several times and finally fixing with the remaining bolts 44 on the same principle as the installation fixing portion 4 of the fifth embodiment, the linear member 3 is It is possible to achieve an optimum tension. As a winding mechanism for adjusting the length of the linear member 3, even an additional support can be adjusted.

  The installation fixing portion 4 of the seventh embodiment shown in FIG. 21 is for fixing a linear member length adjusting column 48 after winding the linear member 3 around the column. The linear member length adjusting column 48 is a construction part of the installation fixing portion 4 that becomes a column of a winding mechanism for adjusting the length of the linear member 3 by winding the linear member 3. In order not to damage the linear member 3, it is desirable that the linear member length adjusting column 48 has no screw groove on the shaft. As long as the shape is columnar, anything can be used by casting, and an anchor bolt 41 or the like can be substituted.

  Although not shown, the installation fixing portion of the eighth embodiment stands up with the linear member length adjusting column 48 as shown in FIG. 21 and winds the linear member 3 around the column. The linear member 3 is fixed to the installation fixing part 4 of one embodiment. As an application of this, it may be considered that the linear member length adjusting column 48 is erected, the linear member 3 is wound around the column, and then the linear member 3 is fixed to the installation fixing portion 4 of FIG. It is done. It is also conceivable that the linear member length adjusting column 48 is erected, the linear member 3 is wound around the column, and then the linear member 3 is fixed to the installation fixing portion 4 of the fourth embodiment of FIG. .

  As a measure against wind pressure, the flexible solar cell assembly is installed with an inclination in the south direction in the short side direction, so that the wind easily escapes in the inclination direction. If a set of a plurality of flexible solar cell assembly rows is installed, it is desirable that the adjacent rows be arranged without gaps and leave a wind escape path. This is because the wind load applied to the flexible solar cell assembly can be greatly reduced. When tilting, if the tilt angle is tilted up to a maximum of 60 degrees, the distance where the neighbor does not become a shadow needs to be the shortest distance between the neighbors in terms of 0 degree installation. As long as it is free, wind pressure can be released at any inclination.

  According to the present embodiment, a flexible solar cell that does not stop on the roof of an existing structure but can be easily mounted and removed by a user in large quantities anywhere, can be easily adjusted and changed by the user, and has excellent durability. A method for installing the assembly and the flexible solar cell assembly can be provided.

  That is, it can be installed in any space other than the roof with a large capacity area. There is no limit to the installation area, and it can be installed in any space other than the roof with a large capacity. The reason is that it can be installed on a familiar veranda, an existing handrail of a window or the like without being intended to be installed on the roof as in the background art. Also, if a new installation fixing part is installed, it can be installed anywhere. In addition, as supplementary information to further support this, the flexible solar cell assembly is, as a single unit, a simple horizontal thin sheet with no high walls in the height direction, which is not a living space for human beings, Since it does not fall under the standard law building, it can be said that the building can be installed without a strict coverage. The definition of a building in the Building Standards Act is Article 1-4, Item 1-4, but the basic policy is literally built in the height direction. It is considered as a building other than a building. Also, it is a single building with a height, chimneys exceeding 6m, pillars exceeding 15m, advertising towers exceeding 4m, billboards, decorative towers, monuments, etc. , An elevated water tank exceeding 8m, silo, tower, etc., and a retaining wall exceeding 2m, and a manufacturing facility specified in item 3, such as a tourist elevator specified in Article 88, paragraph 2 and a recreational play facility using a motor, It is a storage facility, an amusement facility, an elevator such as an elevator or escalator as defined in Article 87, paragraph 2, but it is not applicable as a work piece because it is a single, thin sheet with little height.

  The installation work does not require a specialized contractor, does not require material costs such as a frame or a steel plate, and the user can install it without many processes and construction periods. Even if it is assumed that the installation fixing part is newly installed, the installation work cost is saved as compared with the previous work. The reason is that existing windows other than the roof of the background art, handrails on the veranda, etc. can be used as the installation fixing part, so that installation of a new installation fixing part can be saved and the user himself can install it. Even if it is assumed that a new installation fixing part is installed, it is only necessary to install four anchor bolts at the lowest cost as a material for the installation fixing part for a large number of flexible solar cell assemblies. This is because the cost of installation can be saved by using inexpensive materials and simplifying the construction.

  It can be installed in a conspicuous space, and appeals to environmental activities from the standpoint of the installed user. The reason is that in the case of the background art, since it is installed on the roof, it cannot be seen from below, but in this embodiment, it is installed in a space other than the roof and is very conspicuous from below. .

  It can be installed and removed by the user, and can be easily moved to another house in an emergency. The reason is that when installed on the roof as in the background art, it is completely fixed and difficult for the user to remove. This is because the linear member 3 can be easily removed.

  A business model like rental is likely to be born. The reason for this is that, in the case of the background art, the construction cost is increased due to the fixed installation, but in this embodiment, the user can easily attach / remove to any place where the user is easily hooked. This is because the construction cost does not incur and it is easy to lend it as a flexible solar cell assembly.

  The increase in temperature can be suppressed, and the degradation of power generation can be greatly reduced. The reason is that when a thin film type is applied to the flexible solar cell assembly, the temperature of the flexible solar cell module is remarkably reduced due to the heat dissipation effect installed in the space, and loss of power generation can be prevented. In addition, the user can easily change the installation angle and direction in consideration of generation of power generation due to temperature rise.

  The problem is that the adhesion of the flexible solar cell assembly due to the temperature at the time of surface bonding is removed. The reason is that the need for bonding is eliminated because it is installed in the space without being bonded to the surface. Other than the place in contact with the surface such as the roof, it can be installed suspended in the air, for example.

  The flexible solar cell module can be suspended in the space stably for a long period of time by reducing its own weight, wind pressure, mechanical load such as balls and reeds, and improving environmental resistance such as salt damage. The reason for this is that two or more integrally formed conduit molding parts in the long side direction of the flexible solar cell assembly distribute the lifting force evenly over the length of the long side in the linear part. This is because the load is not easily applied to the flexible solar cell module. This is because the tensile load of the linear portion is not conducted to the flexible solar cell module, and the mechanical load is reduced. Generally, when it is simply suspended, it is usually the case that the flexible solar cell module itself is locally fixed and pulled, and there is a possibility that the flexible solar cell module itself is destroyed by the tensile tension. This is because the tensile member does not conduct because the linear member is only in contact with the conduit molding part. In particular, film-type flexible solar cell modules are liable to break the thin film structure due to tensile tension, and it is better not to pull the flexible solar cell module directly. Like this embodiment, it can respond so that force may not be conducted by a long conduit molding part. Since the entire flexible solar cell module is completely sealed in a hollow manner, the external force is preferentially absorbed by the tensile tension in the short side direction of the conduit molding part, and the tensile tension is conducted directly to the flexible solar cell module. do not do. In addition, the entire surface protection can reduce the damage to the flexible solar cell module directly caused by baseballs and balls, etc., and the damage to the module surface is reduced, so the environmental resistance such as salt damage is not destroyed. Retained.

  A flexible solar cell assembly can be stably suspended in a large amount of space at a time. Even in the process of installing the flexible solar cell assembly in a high space around nothing other than the roof and walls, the flexible solar cell assembly does not slip from the lower end of the wire even if the wire is tilted for bridging. The inclination angle of the flexible solar cell assembly can be easily changed. This does not cause a decrease in annual power generation. Even with the space installation distance of the flexible solar cell assembly from shore to shore, it is not expensive to adjust the wire tension.

  Furthermore, the following auxiliary effects increase by the additional function of a linear member and the additional function of a fixed installation part. As a first auxiliary effect, a large number of flexible solar cell assemblies can be suspended at a time by the linear member. The reason is that the end of the linear member is completely closed loop rather than simply being tied up by a human being, so that the connection with the installation fixing portion is ensured and cannot be removed. In addition, it becomes possible to suspend a large amount in the space at a long distance by using a high-strength material such as Dyneema as the material of the linear member and increasing the thickness.

  As a second auxiliary effect, in the process of installing the flexible solar cell assembly in a high space without anything other than the roof and walls, it is easy for the user to move from the shore of the installation location to the opposite shore without using large tools. It can be made to bridge. This is because the user can perform the following installation process using a linear member without using a special tool. That is, first, the conduit molding part of the flexible solar cell assembly is passed through the linear member as much as the bridging distance. Thereafter, stoppers are attached to the linear members on both sides of each conduit molding portion of the flexible solar cell assembly. Connect the end of the linear member to the fixed installation part of the installation site, and slowly lower the end of the other linear member from the shore to the ground. At this time, each of the flexible solar cell assemblies is fixed to the linear member by the support of the stopper of the linear member, and does not come off from the linear member. One side of another linear member is temporarily connected to the other fixed installation part on the opposite bank, and a detachable coupler is connected to the other side and lowered to the ground. Once on the shore, the detachable coupler on one side of the one linear member is connected to the two or more ends of the linear member that was initially lowered. Return to the fixed installation part on the opposite bank, and lift the ground side of the linearly connected part from the ground. If the end of the pulled-up linear member is connected to the fixed installation part on the opposite bank, the bridge from the bank to the opposite bank can be easily and reliably performed in this way. Since only the detachable connector and the linear part need be used as tools, the user does not need to lift using a large tool such as a crane.

  As a third auxiliary effect, the additional function of the installation fixing portion makes it possible to easily attach and remove while maintaining the durability of the installation, and to easily change the inclination angle of the flexible solar cell assembly. This is to increase the annual power generation. The reason is that by adding a detachable closed loop connection structure to the installation fixing portion embedded in the solid support foundation, the connection between the end portion of the linear member and the closed loop portion becomes strong. Furthermore, the inclination angle of the flexible solar cell assembly can be easily changed by adjusting the height of the connecting position of the left and right installation fixing portions. Further, by increasing the thickness and thickness of the installation fixing part, it is possible to provide the installation fixing part with the strength to suspend a large amount in space over a long distance.

  As a fourth auxiliary effect, the length of the linear member can be easily adjusted without using an expensive device such as a special turn buckle or winch by the additional function of the installation fixing part. Can be increased. The reason is that the linear member can be wound once around another rod-shaped member to adjust the length, and the connecting structure of the closed loop portion from which the installation fixing portion can be removed is connected.

[Second Embodiment]
Next, the flexible solar cell assembly and the installation method of the flexible solar cell assembly according to the second embodiment of the present invention will be described. Detailed description of the same elements as those in the first embodiment is omitted. FIG. 4A is a plan view of the flexible solar cell assembly according to the second embodiment of the present invention, and FIG. 4B is a side view of the long side of the flexible solar cell assembly, and FIG. Fig. 4 is a side view of the flexible solar cell assembly on the short side, and Fig. 4 (d) is a partially enlarged view of a portion D in Fig. 4 (c).

The flexible solar cell assembly according to the present embodiment includes the pair of suspended portions 24 provided between the pair of conduit molding portions 23 and the main body portion 21 in the flexible solar cell assembly according to the first embodiment described above. is there. That is, as shown in FIG. 4 (c) and FIG. 4 (d), the conduit molding part 23 is molded in advance in a shape in which the direction is bent upward. The difference between the case of FIG. 3 and the case of FIG. 4 is only the difference in the shape of whether or not it is pre-molded so that the portion of the conduit is on top, and the other molding methods are the same.
Here, the bending angle is not limited, but 90 degrees, which is the direction in which the force is applied, is preferable. The reason for this is that even if the flexible solar cell module 1 is originally horizontal as shown in FIG. 3, the conduit member of the conduit molding portion 23 can be bent by being pulled up by the linear member 3 due to the weight of the flexible solar cell module 1. There is sex. This is because it is difficult to apply an excessive force to the plastic when it is bent and molded from the beginning as shown in FIG. Moreover, since the area is also reduced, the area efficiency of photovoltaic power generation is slightly improved.

  The flexible solar cell assembly according to the second embodiment can also be installed in a manner as shown in FIGS. According to the flexible solar cell assembly of the present embodiment, the same effects as those of the flexible solar cell assembly according to the first embodiment described above are provided. Furthermore, according to this embodiment, since it is bent and molded from the beginning in a direction in which a force is applied as shown in FIG. 4, it is difficult to apply an excessive force. Moreover, since the installation area is reduced, the area efficiency of photovoltaic power generation is also slightly improved.

[Third Embodiment]
Next, the flexible solar cell assembly and the installation method of the flexible solar cell assembly according to the third embodiment of the present invention will be described. Detailed description of the same elements as those in the first embodiment is omitted. FIG. 5A is a plan view of the flexible solar cell assembly according to the third embodiment of the present invention, and FIG. 5B is a side view of the long side of the flexible solar cell assembly, and FIG. FIG. 5 is a side view of the short side of the flexible solar cell assembly, and FIG. 5D is a partially enlarged view of a portion E in FIG. 5C. FIG. 22A is a side view of the installation fixing unit 4 of the eighth example used for installation of the flexible solar cell assembly according to the present embodiment, and FIG. FIG. 22C is a top view, and FIG. 22C is another side view of the installation fixing portion 4.

  The flexible solar cell assembly according to the present embodiment is the flexible solar cell assembly according to the first embodiment described above, along the long side of the flexible solar cell module 1 on one main surface, for example, the lower surface, of the main body 21 of the holding unit 2. It is further characterized by further comprising another conduit forming part 25 arranged. That is, as shown in FIGS. 5 (a) to 5 (d), the number of the linear members 3 corresponding to the conduits of the conduit molding portion of the flexible solar cell assembly is increased so that the flexible solar cell assembly can be viewed from above and below. This brakes the effect of wind pressure. In this embodiment, although the number of the linear members 3 corresponding to the conduit | pipe of the conduit | pipe molding part 25 is increased by one, when the short side of the flexible solar cell module 1 is long, it is also possible to add two or more. Conceivable. Since the short side of the flexible solar cell module 1 is often as short as about 50 cm and the central portion is pushed by wind pressure, it is effective to add one to the central portion. About the position of the additional conduit | pipe of the conduit | pipe shaping | molding part 25, it is desirable on intensity | strength that it is a position equidistant from the long side of the flexible solar cell module 1. FIG. If there is a conduit on the surface, sunlight is attenuated, so it is integrated with the bottom surface. When the conduit is attached to the lower surface, the width of the linear member 3 is the lowest width so that the braking force of the linear member 3 stretched to the pin is in direct contact, and the height is a rectangle or ellipse through which the linear member 3 passes. The shape of the conduit is preferred. As for the method of attaching the conduit, it is integrated and molded in advance from the stage of molding of the conduit molding portion. Alternatively, a conduit having the same length as the long side of the conduit molding portion may be separately molded and welded to the lower surface of the conduit molding portion to complete the integration. From the stage of the mold, it is desirable to mold it integrally because it is suitable for mass production and has high strength.

  The flexible solar cell assembly according to the third embodiment can also be installed by adding the linear member 3 necessary for the mode as shown in FIGS. 1 and 2. According to the flexible solar cell assembly of the present embodiment, the same effects as those of the flexible solar cell assembly according to the first embodiment described above are provided. Furthermore, according to this embodiment, since the number of the linear members 3 corresponding to the conduit | pipe of a conduit | pipe molding part is increased, compared with the flexible solar cell assembly by 1st Embodiment, from the upper and lower sides to a flexible solar cell assembly. The effect of wind pressure can be braked.

[Fourth Embodiment]
Next, a flexible solar cell assembly and a flexible solar cell assembly installation method according to a fourth embodiment of the present invention will be described. Detailed description of the same elements as those in the first embodiment is omitted. FIG. 6A is a plan view of the flexible solar cell assembly according to the fourth embodiment of the present invention, and FIG. 6B is a side view of the long side of the flexible solar cell assembly, and FIG. FIG. 6 is a side view of the flexible solar cell assembly on the short side, and FIG. 6D is a partially enlarged view of portion F in FIG. 6C.

  The flexible solar cell assembly according to the present embodiment is characterized in that, in the flexible solar cell assembly according to the first embodiment described above, a protective sheet is further provided on one main surface of the main body portion 21 of the holding portion 2. That is, as shown in FIGS. 6 (a) to 6 (d), the flexible solar cell module 1 is placed on the top of the flexible solar cell module 1 so as to be in horizontal contact with the uppermost and lowermost portions of the conduits of the conduit molding portion 23 of the flexible solar cell assembly. A protective sheet 26 is provided on the entire lower surface. The protective sheet 26 may be integrated later by welding, but it is preferable to mold the protective sheet 26 in advance using a plastic integral molding method. The flexible solar cell module 1 according to the first embodiment is in a hollow state in which the conduit molding part 23 and the flexible solar cell module 1 are in contact with each other, although complete hermetic protection is provided. According to the flexible solar cell assembly according to the present embodiment, since the protective sheet 26 of the conduit molding part 23 and the flexible solar cell module 1 are completely separated, a hollow state in which the flexible solar cell module 1 is completely floated can be created. Note that the protective sheet newly added in FIG. 6 only protects the direction perpendicular to the paper surface in the side view shown in FIG. 6 (b), and up to the direction perpendicular to the paper surface in the side view shown in FIG. 6 (c). It is desirable not to protect it from the viewpoint of heat dissipation. This is because ventilation in a direction perpendicular to the paper surface in the side view shown in FIG.

  The flexible solar cell assembly according to the fourth embodiment can also be installed in a manner as shown in FIGS. According to the flexible solar cell assembly of the present embodiment, the same effects as those of the flexible solar cell assembly according to the first embodiment described above are provided. Furthermore, according to this embodiment, the environmental resistance of the flexible solar cell assembly can be enhanced by the protective sheets 26 provided on the entire upper and lower surfaces of the flexible solar cell assembly. Furthermore, it becomes difficult to bend greatly in the short side direction of the flexible solar cell assembly. For example, if the wind pressure is applied from the upper part and the central part of the short side is bent, the central part becomes difficult to be bent by the tension of the protective sheet 26 at the lowermost part. Further, since the shape is improved so that the wind does not collect easily, the wind pressure escapes to the left and right, and the central portion is difficult to bend from the top of the wind pressure. In this respect, if the conduit shape is circular, the effect of making it easier for the wind to escape to both ends is produced by the round effect at both ends. Furthermore, since the distance from the flexible solar cell module 1 is also far away, the local acute pressure is not transmitted to the flexible solar cell module 1 even when an acute angle such as a bag hits locally from above. There is also. The acute mechanical pressure may cause local destruction of the flexible solar cell module 1, and the effect that can be protected from this is great.

  In particular, when the distance is separated from the flexible solar cell module 1 and protection is performed by a two-layer protective sheet, it is difficult to receive wind pressure in terms of shape. Furthermore, the flexible solar cell module 1 becomes difficult to bend due to the protection of the hollow structure at a distance due to wind pressure. In addition to this, even if an acute mechanical force such as a heel is applied, there is an effect that the acute mechanical force is not directly transmitted to the flexible solar cell module 1, and the environment resistance is increased and the long-term stability is increased. Can be suspended in space.

[Fifth Embodiment]
Next, the flexible solar cell assembly and the installation method of the flexible solar cell assembly according to the fifth embodiment of the present invention will be described. Detailed description of the same elements as those in the fourth embodiment is omitted. FIG. 7A is a plan view of a flexible solar cell assembly according to a fifth embodiment of the present invention, and FIG. 7B is a side view of the long side of the flexible solar cell assembly, and FIG. FIG. 7 is a side view of the flexible solar cell assembly on the short side, and FIG. 7D is a partially enlarged view of portion G in FIG. 7C. FIG. 22A is a side view of the installation fixing unit 4 of the eighth example used for installation of the flexible solar cell assembly according to the present embodiment, and FIG. FIG. 22C is a top view, and FIG. 22C is another side view of the installation fixing portion 4.

  The flexible solar cell assembly according to the present embodiment is characterized in that the flexible solar cell assembly according to the fourth embodiment described above further includes another protective sheet. That is, in the flexible solar cell assembly according to the present embodiment, a cylindrical protective sheet 27 is further provided as shown in FIGS. 7 (c) and 7 (d). The protective sheet 27 has a circular cross section as shown in FIG. Furthermore, in order to prevent the round shape of the protective sheet 27 from being crushed, another linear member 3 is stretched inside the uppermost part and the lowermost part of the protective sheet 27 as shown in FIG.

  The protection sheet 27 enhances the aerodynamic characteristics of the flexible solar cell assembly and prevents the influence of wind pressure from being significantly conducted to the flexible solar cell module 1. Compared to the flexible solar cell assembly according to the fourth embodiment described above, the aerodynamic characteristics are further improved. The protective sheet 27 may be integrated later by welding, but it is desirable that the protective sheet 27 is preliminarily molded by a plastic integral molding method. In the present embodiment, a circular shape is used for easy understanding of the description, but a sufficient aerodynamic effect can be obtained even with an ellipse, and it is not necessary to make the shape higher and lower than necessary. This reduces the effect of wind pressure on the flexible solar cell assembly as follows. First, the influence of the wind pressure from the side surface of the flexible solar cell assembly is first attenuated as the wind pressure is blocked by the adjacent flexible solar cell assemblies. Due to the aerodynamic characteristics of the round shape, the wind pressure further escapes up and down and attenuates. In addition, since the tension of the linear member 3 holds a force that does not lose against the wind pressure, an unreasonable force is not applied to the flexible solar cell module 1. The influence of the wind pressure from the front of the flexible solar cell assembly has little influence because the wind passes through the cylindrical shape. Rather, the wind pressure in this direction is an advantage of enhancing the heat dissipation effect, and the amount of power generation increases. Since the wind pressure from the upper surface direction or the lower surface direction of the flexible solar cell assembly is first received by the tension of the linear member 3 at the upper center or lower center, the central portion of the flexible solar cell module 1 is not directly pressed. Therefore, the flexible solar cell module 1 does not even bend. In terms of aerodynamic characteristics, the round shape effectively releases the wind pressure to the side, and the wind pressure is attenuated.

  On the other hand, the flexible solar cell module of United-Solar Uni-Solar series is a high-strength module in stark contrast to the delicate Fuji Electric Systems. Although it is thin as well, the surface is ETFE, and the back is a structure with a rubber adhesive on the metal, and the properties differ between the front and back. The adhesive on the back side will not adhere unless the seal is peeled off, so leave the seal intact. The difference from the one manufactured by Fuji Electric Systems Co., Ltd. when applying this embodiment is that it is reinforced by a relatively thick metal plate with high strength, so that the thin film of the power generation section may be destroyed even under wind pressure. There is no sex. Usually, the flexible solar cell module is weak against mechanical pulling, but this is an example of exceptional strength. Since a heavy metal plate is included and a load due to weight increases, there is a difference in that exceptional measures are implemented by increasing the thickness of the sheet of the main body part, increasing the diameter of the linear member, or bolting the metal plate. The other materials and shapes are the same as those manufactured by Fuji Electric Systems. Although the metal plate manufactured by UnitedSolar is stainless steel, it is desirable to apply to the embodiment of the present invention with a flexible solar cell module in which aluminum is added to stainless steel in consideration of heat dissipation.

  The flexible solar cell assembly according to the fifth embodiment can also be installed by adding the linear member 3 necessary for the mode as shown in FIGS. 1 and 2. When installing the flexible solar cell assembly according to the fifth embodiment, the installation fixing part 4 of the eighth example shown in FIG. 22 can be used. The installation fixing portion 4 of the eighth embodiment has a structure in which a multi-stage ladder-like metal fitting 431 that can be moved further in the vertical direction is attached to the installation fixing portion 4 of the sixth embodiment shown in FIG. Thereby, the linear member 3 can be additionally attached up and down. Since there is a winding mechanism, the length of the linear member 3 can be adjusted.

  According to the flexible solar cell assembly of the present embodiment, the same effects as those of the flexible solar cell assembly according to the first embodiment described above are provided. Furthermore, since the aerodynamic characteristic of the flexible solar cell assembly can be enhanced, the influence of wind pressure can be made difficult to be conducted to the flexible solar cell module. The effect of wind pressure can be further reduced by the third-layer protective sheet 27 having a round shape with good aerodynamic characteristics.

[Sixth Embodiment]
Next, a flexible solar cell assembly and a method for installing the flexible solar cell assembly according to the sixth embodiment of the present invention will be described. Detailed description of the same elements as those in the first embodiment is omitted. FIG. 8A is a plan view of a flexible solar cell assembly according to a sixth embodiment of the present invention, and FIG. 8B is a side view of the long side of the flexible solar cell assembly, and FIG. Fig. 8 is a side view of the flexible solar cell assembly on the short side, and Fig. 8 (d) is a partially enlarged view of a portion H in Fig. 8 (c).

  The flexible solar cell assembly according to the present embodiment further includes a fixing member 5 that fixes the main body portion 21 of the holding unit 2 and the flexible solar cell module 1 in a state of penetrating in the flexible solar cell assembly according to the first embodiment described above. It is characterized by that. That is, as shown in FIGS. 8 (a) to 8 (d), holes are made in several places on the long side of the flexible solar cell assembly so as to penetrate the main body 21 and the flexible solar cell module 1, It is fixed by bolting from above and below with a pair of bolts and nuts. In general, as shown in FIG. 8 (a), the positions at several places are preferably four places at the four corners of the flexible solar cell module 1, and the gaps are increased according to the strength and bolted. Either welding or bolting may be selected. However, since the metal is included and the weight is heavy, it can be said that it is desirable in terms of quality to fix securely by both welding and bolting instead of one option.

  The flexible solar cell assembly according to the sixth embodiment can also be installed in the manner as shown in FIGS. According to the flexible solar cell assembly of the present embodiment, the same effects as those of the flexible solar cell assembly according to the first embodiment described above are provided.

Fig. 9 is a side view of the flexible solar cell assembly on the short side, and Fig. 9 (d) is a partially enlarged view of a portion I in Fig. 9 (c).

  The flexible solar cell assembly according to the present embodiment is the same as the flexible solar cell assembly according to the sixth embodiment described above, between the pair of conduit molding portions 23 and the main body portion 21 as in the flexible solar cell assembly according to the second embodiment. A pair of suspended portions 24 is provided. That is, as shown in FIG. 9C and FIG. 9D, the conduit molding part 23 is molded in advance in a shape in which the direction is bent upward.

  The flexible solar cell assembly according to the seventh embodiment can also be installed in the manner as shown in FIGS. According to the flexible solar cell assembly of the present embodiment, the same effects as those of the flexible solar cell assembly according to the first embodiment described above are provided. Furthermore, according to this embodiment, since it is bent and molded from the beginning in a direction in which a force is applied as shown in FIG. 9, it is difficult to apply an excessive force. Moreover, since the installation area is reduced, the area efficiency of photovoltaic power generation is also slightly improved.

[Eighth Embodiment]
Next, a flexible solar cell assembly and an installation method of the flexible solar cell assembly according to an eighth embodiment of the present invention will be described. Detailed description of the same elements as those in the first embodiment is omitted. FIG. 10A is a plan view of the flexible solar cell assembly according to the eighth embodiment of the present invention, and FIG. 10B is a side view of the long side of the flexible solar cell assembly, and FIG. These are the side views of the short side of this flexible solar cell assembly.

  The flexible solar cell module manufactured by UnitedSolar has exceptional characteristics as a flexible solar cell module that is originally highly environmentally resistant and durable. This embodiment takes advantage of the characteristics of this exceptionally strong flexible solar cell module.

  The flexible solar cell assembly of the present embodiment includes a substantially rectangular flexible solar cell module 1 having a long side and a short side, and a holding unit 2 that hermetically holds the flexible solar cell module 1 in a hollow state. A holding body having a thin belt-shaped hollow structure main body 21 for sealing the battery module 1 and a closed loop conduit penetrating in the long side direction of a pair provided in the main body 21 along the long side of the flexible solar cell module 1 The unit 2 is provided. In the present embodiment, as an example of a closed loop conduit that penetrates in the long side direction of the pair, it is fixed to the main body portion 21 of the holding portion 2 and is spaced along the long side of the flexible solar cell module 1 of the main body portion 21 of the holding portion 2. A plurality of ring-shaped members 6 arranged at a distance are used. The ring-shaped member 6 is fixed by making holes in several places on the long side of the flexible solar cell assembly so as to penetrate the main body 21 and the flexible solar cell module 1. Each ring-shaped member 6 has a ring-shaped portion 61, and the linear member 3 is passed through the plurality of ring-shaped portions 61 along the long side direction of the flexible solar cell assembly. Here, as the ring-shaped member 6, an inexpensive eyebolt is used. FIG. 10A shows a case where eight eyebolts are used. A hole is drilled in the flexible solar cell assembly, an eyebolt is inserted, the nut is tightened and fixed, and the flexible solar cell module 1 is integrated.

  In the case of making by special casting, since the length of the ground contact with the linear member 3 is longer if possible, the shape of the conduit longer than the eyebolt, the braking force of the linear member 3 is likely to work. . Even if it is too long, the weight is too heavy, so make it an appropriate length. This embodiment is applicable to a flexible solar cell module manufactured by UnitedSolar, which is reinforced with a relatively thick and strong metal plate. Any bolt other than an eyebolt can be used as long as the bolt has a strong closed loop shape. For example, it is conceivable that the eye portions are bent out on both sides by bending in the short side direction of the flexible solar cell module without raising the eye portions. In the present embodiment, eight eyebolts are used. However, in the case of a flexible solar cell module having a short long side and a small amount of deflection, it may be provided at least at four corners, that is, four eyebolts may be provided.

  The flexible solar cell assembly according to the eighth embodiment can also be installed in a manner as shown in FIGS. According to the flexible solar cell assembly of the present embodiment, a flexible solar cell assembly and a flexible solar cell assembly that can be easily mounted and removed in large quantities anywhere, not only on the roof of an existing structure, and excellent in durability. Can provide installation methods.
