Description

  The present invention relates to a frame for a solar power device for fixing a solar power device such as a solar cell module that generates power using solar energy, and a method for installing a solar power device using the same. .

  In recent years, with increasing interest in global environmental problems, new energy technology using natural energy has attracted attention. As one of them, there is a strong interest in renewable energy systems that use solar energy, and in particular, the spread of solar-powered systems with solar cell panels and solar thermal collector panels mounted on rooftops has been accelerated. It is coming. Moreover, in order to arrange a solar cell module on the roof of a house, various structures for mounting the solar cell module on the roof have been devised. One of the mounting methods adopted by many of them is a roof-mounted solar power generation system in which a roof frame is assembled by combining support members on a roof and a solar cell module is fixed thereto.

  FIG. 9 is a perspective view showing a general residential solar power generation system.

  In FIG. 9, the photovoltaic power generation system is fixed to a plurality of solar cell modules 1 that convert sunlight into electric energy, and a roof that is attached to the back surface of these solar cell modules 1 although not shown in detail. Roof frame 2, a junction box 3 for collecting electric energy generated by the plurality of solar cell modules 1, and a power conditioner 4 for converting DC power into AC power. Usually, the DC power generated by the solar cell module 1 is put into the connection box 3 by a power transmission cable. And after the series system of a plurality of solar cell modules is connected in parallel in the junction box 3 and aggregated, it is converted into AC power by the power conditioner 4 and used as household power, or the amount of power generation is used at home. If it is greater than the power, it is sold to the commercial power grid of the power company.

  FIG. 10 is a partial cross-sectional view showing the structure of a general solar cell module.

  In FIG. 10, a transparent substrate 5 such as tempered glass is provided on a surface on which sunlight is incident, and a solar cell element 6 is wrapped with a filler 7 such as ethylene vinyl acetate (EVA), and a material such as PET is provided on the back surface. The back sheet 8 made in (1) is pasted, and these are bonded by a crosslinking treatment. A frame member 9 made of aluminum or the like as a reinforcing member is provided around the periphery, so that the power generation unit is protected and attached to the rack system described above. Moreover, the junction box 10 and the cable 11 for taking out the electric power which the solar cell element 6 produced | generated are provided in the back surface, ie, non-light-receiving surface, of a solar cell module.

  11 (a) to 11 (d) are cross-sectional views showing a construction procedure of a conventional flat panel fitting structure, and FIGS. 12 (a) and 12 (b) show a water stop member in the conventional flat panel fitting structure. FIG. 13 is a perspective view schematically showing the flow of rainwater that has entered in a conventional flat panel fitting structure portion.

  First, as shown in FIG. 11A, a thin solar cell module 12 having no mounting holes or the like in a frame portion is fixed on a roof base plate 13 with a fixing member 16 and a fixing rack 14 with screws or bolts. Then, one end of the solar cell module 12 is inserted into the fitting groove 15 provided in the fixed rack 14. At this time, the height of the groove of the fitting groove 15 is slightly larger than that of the solar cell module 12 since it has a role of holding the solar cell module 12 so as not to move. If the module 12 is tilted, it does not enter the fitting groove 15. Therefore, only by lowering the other end of the solar cell module 12 to the fixing member 16 as shown by the arrow 18, a part of the solar cell module 12 protrudes outside the fixing member 16 as shown in FIG. become. Therefore, by horizontally moving the solar cell module 12 in the direction of the arrow 19 and inserting it to the back of the fitting groove 15, the end of the solar cell module 12 and the fixing member 16 are inserted as shown in FIG. The position can be adjusted. Finally, by attaching the holding member 17 to the fixing member 16 with a screw or the like, the solar cell module 12 cannot be removed from the fitting groove 15 as shown in FIG.

  In this example, the right side in the figure is the ridge side, and the left side is the eaves side.However, as a fixed structure that uses fixing members on the ridge side, it functions in the same way even if the roles of the eaves and ridges are reversed. Needless to say. In addition, although fixed members and fixed racks are arranged directly on the roof base plate, the same applies when they are arranged on a rack system that combines metal rails such as iron, stainless steel, and aluminum installed on roof tiles. is there.

  In recent years, a solar power generation system using a roof material integrated solar cell module has been attracting attention. Unlike the conventional structure, the solar cell module can be used as a roofing material by placing the solar cell module on the base plate and making it possible to combine tiles in the left and right and flow direction. is there. In general, a roof material-integrated solar cell module is required to have performances such as contact with tiles and prevention of intrusion of rainwater by devising the structure of the frame material. However, the load on the roof is reduced, the intrusion of rainwater is easier to prevent than the roof type, the unity with the roof is increased, and the appearance is very beautiful. In addition, construction on a new property has the advantage of being easier to construct than a roof-mounted type.

  However, the roof material-integrated solar cell module has conventionally been able to work with surrounding tiles by devising the structure of its outer frame, but it can be easily removed if the installed solar cell module fails. There was a demerit that it was not. There is also a problem that it can only be combined with one type of roof material or a limited structure.

  Therefore, by separating the solar cell module and the surrounding frame material structure, inserting one end of the solar cell module into the insertion slot, and fixing the other using another fixing member, at the time of failure An invention has been devised that makes it possible to remove the solar cell module (see, for example, Patent Document 1).

  In addition, after inserting one end of the solar cell module into the insertion port (building side), rotate the solar cell module so that it is parallel or nearly parallel to the roof surface, and then insert the other insertion port (eave side) ) Has been proposed (see, for example, Patent Document 2).

In addition, a method of fixing by providing an engaging portion between the frame and the solar cell module has been proposed (see Patent Document 3).
JP 2000-352154 A International Publication Number WO02 / 041407 JP 2001-90264 A

  However, in the above-described conventional technology, as a construction procedure, first, (1) the solar cell module 12 is fitted into the recessed portion 15, and the solar cell module 12 is dropped as it is in a direction parallel to the roof surface. The solar cell module 12 is pushed in the direction of 15, and (3) is finally composed of three steps of fixing the solar cell module using the fixing member 16 and the holding member 17 provided on the side opposite to the concave portion 15. Yes, in the insertion step of (2) in this process, if the dimensional accuracy of the recess 15 is too good, the solar cell module 12 is difficult to enter, or if the solar cell module is forcibly inserted, the clamping force of the recess 15 Excessive pressure and strain occur in the solar cell module, resulting in small cracks called microcracks in the solar cell element. Solar cell module resulting in failure. In addition, the dimensional accuracy of the solar cell module must be increased, which makes manufacture difficult. On the other hand, when the dimensional accuracy of the recess 15 is loosened, a gap is generated between the solar cell module 12 and the recess 15, and the solar cell module 12 hits the recess 15 due to external force such as wind, or noise is generated. I will let you. Further, in order to prevent this, when butyl rubber or the like is disposed on the outer periphery of the frame member or the frame member portion of the solar cell module to reduce the clearance, there arises a problem that the number of members and construction man-hours increases.

  Further, for example, in the case of very strong wind and rain such as a typhoon, rainwater is sprayed between the solar cell module 12 and the recess 15 as shown by an arrow 48 in FIG. End up. Once rainwater enters, it cannot easily escape, but since it is inclined to the solar cell module side, it wraps around the back side of the solar cell module 12 as indicated by an arrow 46 in the figure and falls on the roof. A part of the water also flows down onto the roof mounting portion 18 below the fixed rack 14, but at this time, rainwater flows onto the roof from the through hole 19 for screwing the fixed rack 14 onto the roof. Generally, even a small amount of rainwater can often cause rain leakage if it continuously intrudes, which can cause serious problems such as deterioration and rotting of field plates. Thus, since only the fixing method of inserting the solar cell module 12 into the fitting groove portion 15 of the fixing rack 14 cannot prevent rainwater from falling onto the roof of the house, the roof needs to be separately waterproofed.

  Furthermore, as a method for solving the above-mentioned waterproofing problem, as shown in FIG. 12A, a water-stopping packing 40 is provided in the recess 15 of the fixed rack 14 and the solar cell module 12 is inserted into the recess 15, As shown in FIG. 12 (b), a method is generally used in which the water-stopping packing 40 fills the gap between the solar cell module 12 and the recess 15 to form a water-stopping structure. However, it is necessary to deform the water-stopping packing by pushing the solar cell module with a certain force or more, resulting in a burden on the operator and poor workability.

  The present invention has been invented to solve the above problems, and its purpose is to prevent damage to solar equipment when the solar equipment is inserted into a fixed rack. The object is to provide a frame for a solar-powered device excellent in water-stopping and workability and a method for installing a solar-powered device using the frame.

  The solar-use equipment frame of the present invention is a solar-use equipment frame into which an end of the solar-use equipment is fitted, a fixed rack having a placement surface on which the solar-use equipment is placed, and the sun A fixing member having a concave portion into which an end portion of the light-utilizing device is inserted and a support portion that supports a lower surface of the solar-powered device, and the concave portion includes a pressing portion that presses the upper surface of the solar-powered device. And a groove portion recessed downward from the lower surface of the solar-powered device.

  According to another aspect of the present invention, there is provided a frame for solar-powered equipment, wherein the solar-powered equipment includes a dummy panel in the frame.

  Furthermore, another frame for solar-powered equipment according to the present invention is characterized in that an elastic member that is elastically deformed is disposed in the recess in the frame.

  On the other hand, the method for installing a solar-powered device according to the present invention prepares the above-described solar-powered device frame and the solar-powered device, and tilts the solar-powered device with respect to the mounting surface of the fixed rack. The step (a) of inserting one end portion of the solar-powered device into the groove portion of the concave portion of the fixing member in the state where the solar-powered device is inserted, and the sun as a base point from the one end portion of the solar-powered device inserted into the groove A step (b) of rotating the other end of the light utilization device downward, a step (c) of placing the other end of the solar light utilization device on the placement surface of the fixed rack, and the solar light utilization device. The solar-use device is fixed to the frame through the step (d) of supporting one end of the fixing member by the supporting portion of the fixing member and pressing the pressing portion of the fixing member. To do.

  Moreover, the installation method of the other solar power utilization apparatus of this invention is the said installation method. WHEREIN: By performing the said process (c) and process (d) substantially simultaneously, the one end part of the said solar power utilization apparatus is the said recessed part. The solar light utilization device is fixed to the frame while being in contact with an inner wall.

  Furthermore, the installation method of the other solar-powered device of the present invention is characterized in that, in the installation method, an elastic member that is elastically deformed is inserted into the concave portion of the fixed rack before the step (a).

According to the present invention, a fixed rack having a mounting surface on which the solar-powered device is mounted;
A fixing member having a recess into which an end portion of the solar power utilization device is inserted and a support portion that supports a lower surface of the solar power utilization device, and the recess presses the upper surface of the solar power utilization device. Part and a groove portion that is recessed below the lower surface of the solar-powered device, so that excessive stress is not applied to the end of the solar-powered device, Since it can be fixed to the fixing member satisfactorily, it is possible to suppress damage to the solar-powered device and it is excellent in water-stopping property.

  According to the invention, the step of inserting one end portion of the solar light utilization device into the groove of the concave portion of the fixing member in a state where the solar light utilization device is inclined with respect to the mounting surface of the fixed rack ( a), a step (b) of rotating the other end of the solar-powered device downward from the one end of the solar-powered device inserted into the groove, and the other end of the solar-powered device (C), and a step of supporting one end portion of the solar-powered device with the support portion of the fixing member and pressing with the pressing portion of the fixing member. Since the solar-powered device is fixed to the fixing member through (d), the workability is superior compared to the conventional case.

  Further, according to the present invention, the step (c) and the step (d) are performed almost simultaneously, so that one end portion of the solar-powered device is brought into contact with the inner wall of the recess, and the solar-powered device is Since it is fixed to the frame, the step of pushing in the solar-powered device does not occur as compared with the conventional construction method. Therefore, the construction process is reduced by one compared with the prior art, thereby improving the construction speed.

  Further, by providing a sufficient allowance for the size of the concave portion, the installer can easily guide the solar-powered device to a desired position on the fixing member when tilted.

  Further, the groove portion in the present invention can also serve as a ridge, and the invading water is transmitted to the back side of the solar-powered device, for example, in the case of a roof material-integrated solar cell, a water stop such as a field plate fixing portion Rainwater can be prevented from flowing to the weak areas.

  Further, in the prior art, the insertion structure portion and the heel structure portion had to be provided separately. However, in the present invention, these functions can be provided at the same time. For example, the number of parts is increased or the heel structure is provided. An increase in material costs is suppressed.

  Further, by inserting an elastic member into the recess, it is possible to provide a mechanism for preventing the falling of the solar-powered device, and an effect of improving safety or reducing the number of members can be obtained.

  Hereinafter, an example of an embodiment of the present invention will be described in detail with reference to the drawings schematically shown, taking as an example a state in which a solar cell module, which is a solar-powered device, is fitted on a gantry and fixed using a structure.

  FIG. 1 is a perspective view showing a state in which a solar cell module is placed using the solar cell module frame of the present invention, and FIGS. 2 (a) and 2 (b) are perspective views showing the arrangement and assembly of components. FIGS. 3A to 3C are cross-sectional views for explaining the assembly procedure.

  As shown in FIG. 1, the mounting structure of the solar cell module using the frame of the present invention includes a solar cell module 24, a fixed rack 27 on which one end side of the solar cell module 24 is mounted, and an opposing solar cell. And a fixing member 31 on which the other opposite side of the module 24 is placed. The fixed rack 27 includes a support portion 30 and a concave portion (which includes a pressing portion 28 and a groove portion 29). The fixing member 31 has a mounting surface 33, a holding member 32, and a fastening bolt 34.

  As shown in FIG. 2A, the fixing rack 27 is fixed to the roof base plate 13 with a wood screw 35, and similarly, the fixing member 31 fixed to the base plate 13 with the wood screw 35 of the solar cell module 24. Two opposing sides are placed. At this time, one side of the solar cell module 24 is inserted into the groove portion 29 in an inclined state, and the opposite side is lowered onto the mounting surface 33 as shown in FIG. However, two sides are supported by the support portion 30 of the fixed rack 27 and the mounting surface 33 of the fixed member 31. Further, the surface side of the solar cell module 24 is prevented from being lifted by the pressing portion 28 of the fixing rack 27 and the holding member 32 screwed to the fixing member 31 with the fastening bolt 34.

  The manner in which the above-described solar cell module is fixed will be described in detail with reference to FIG. As shown in FIG. 3A, the fixed rack 27 and the fixing member 31 are fixed on the roof base plate 13 with wood screws 35. One side of the solar cell module 24 is inserted into the groove 29 from the opening between the pressing portion 28 and the support portion 30 of the fixed rack 27.

  Next, the opposite sides of the solar cell module 24 are lowered to the fixing member 31. At this time, one side of the solar cell module 24 can move in the horizontal direction around the support portion 30 in the groove 29 (exactly Is also in a state of being moved up and down at the same time when moving in the horizontal direction), and is in a free state with respect to rotation from the inclined state to the horizontal state with the support portion 30 as a fulcrum. The end portion 24a can be placed while being aligned in the horizontal direction so that the end portion 24a descends to a predetermined position of the fixing member 31. Therefore, as shown in FIG. 3B, the solar cell module 24 can be brought into a substantially horizontal state, and at the same time, the alignment between the end 24a and the end of the mounting surface 33 can be completed.

  A part of the restraining member 32 protrudes so as to cover the surface side (sunlight receiving surface side) of the solar cell module 24, and is fixed to the mounting surface 33 with a fastening member as shown in FIG. This stops the movement of the solar cell module 24 in the horizontal direction and the upward direction. In addition, the other side which opposes is stopped by the pressing part 28 and the support part 30 of the fixed rack 27 in the vertical direction. In this way, the solar cell module 24 is fixed on the roof.

  FIG. 6A is a cross-sectional view showing another embodiment of the solar cell module frame of the present invention, and FIG. 6B is a cross-sectional view showing a mounting structure when the solar cell module is fixed using the frame of FIG. FIG. 14 is a perspective view schematically showing the flow of rainwater about to enter in the solar cell module frame of the present invention.

  In the construction process described above, there is no need for a process of lowering the solar cell module in the conventional fitting structure once in a horizontal state and then pushing it in, and the construction process is reduced by one compared to the conventional technique, thereby reducing the construction speed. improves. Further, as described above, since the positioning can be performed simultaneously with the lowering, the protrusion 45 is provided at the end portion of the mounting surface 33 of the fixing member 31 as shown in FIG. As shown in FIG. 6B, the solar cell module can be placed on the holding portion 32 on an inclined roof, for example, so that the solar cell module can be temporarily placed without attaching the holding portion 32 during construction. If all the dead weights of 24 can be prevented from being applied, it is possible to avoid the concentrated load on the holding portion 32 and the mounting surface 33 that supports the holding portion 32 and the fastening bolt 34.

  The positional relationship between the holding portion 28 of the fixed rack 27, the support portion 30, and the groove portion 29 may be determined depending on how many times the solar cell module can be inserted into the groove portion 29 in an inclined state. If the presser part 28 is not covered with the cover 30, it can be inserted at an inclination angle close to 90 °, and conversely, the inclination angle becomes shallower as the presser part 28 protrudes on the support part 30. There is an advantage that the water stop performance such as intrusion of water is improved.

  Further, as shown in FIG. 14, the lower end of the groove 29 is made lower than the solar cell module support point of the support portion 30 so that the solar cell module 24 can be inserted. The rainwater 48 that enters the gap is guided in the lateral direction as indicated by the arrow 47 by the groove 29 acting as a kite, and flows into the kite installed on the roof, so that the rainwater leaks onto the field plate. The roof is protected without any problems. Further, in the prior art, the insertion structure portion and the eaves structure portion had to be provided separately. However, in the present invention, since these functions are provided simultaneously, the number of parts can be reduced.

  Next, another embodiment of the present invention will be described.

  FIGS. 4A to 4D are perspective views showing other embodiments of the fixing member for the solar cell module frame of the present invention, and FIGS. 7A and 7B are solar cell module frames according to the present invention. Sectional drawing which shows other embodiment, FIG. 8 (a), (b) is sectional drawing which shows typically the example which performs water stop using the water stop member in the flame | frame for solar cell modules of this invention. is there.

  The cross-sectional structure of the gap groove portion of the fixed rack described above has a groove portion 29 having a curved surface between the pressing portion 28 and the support portion 30 as shown in FIG. 4A, or FIG. As shown in FIG. 4, the solar cell module may be inserted even when the insertion angle of the solar cell module is close to 90 °, and as shown in FIG. 4 (c), the solar cell module may be inclined according to the insertion angle of the solar cell module. It is also possible to have a role of a guide that is inserted smoothly.

  Further, as shown in FIG. 5, the groove 29 of the fixed rack 27 is made elastically deformable, and after the solar cell module 24 is installed, the support portion 30 and the presser portion 28 sandwich the solar cell module 24 and fix it. For example, a force for sandwiching the solar cell module 24 works as shown by an arrow in the figure, so that the solar cell module 24 can be fixed at the same time as the solar cell module 24 is mounted, and the backlash on the fixed rack 27 side can be eliminated. 27 and the dimensional accuracy of the solar cell module 24 can be greatly relaxed. As a method for making the groove portion 29 elastically deformable, for example, only the portion of the groove portion 29 may be deformed by reducing the thickness of the member, or the entire fixed rack 27 is made of a material that can be elastically deformed, and the holding portion 28. Alternatively, the support portion 30 may be made elastically deformable only in the groove portion 29 by using a reinforcing structure such as folding.

  Further, as shown in FIG. 7A, if the water-stopping packing 41 is arranged inside the holding portion 28 of the fixed rack 27, the solar cell module 24 is inserted in an inclined state, and then FIG. ), The water-stopping packing 41 is pressed between the presser portion 28 and the solar cell module 24 to increase the degree of adhesion and improve the water-stopping performance. Moreover, since the water stop packing 41 is held in a pressed state, a force for pressing the solar cell module 24 is also applied to the support portion 30, and the force for fixing the solar cell module 24 is also improved.

  Further, as shown in FIG. 8A, after the solar cell module 24 is placed on the fixed rack 27, the retaining member 51 is inserted into the groove 29 to fix the movement of the solar cell module 24. . In this case, since the solar cell module 24 cannot be rotated with the support portion 30 as a fulcrum, the restraining member 32 is in a state where the end of the solar cell module 24 is stopped by the protrusion 45 as shown in FIG. Even if the solar cell module 24 is not removed, the solar cell module 24 cannot be detached. Therefore, even if the restraining member falls off due to a construction error or external vibration, the solar cell module does not fall off and the safety is improved. Furthermore, as shown in FIG. 8B, it is possible to reduce the number of parts as an unnecessary design of the restraining member by inserting the retaining member 51 on the opposite side to increase the supporting force.

  Next, still another embodiment of the present invention will be described. In this embodiment, the height of the fixing member can be adjusted.

  As shown in FIG. 15, the solar power generation device S installed on the roof is fixed with a solar cell module 61, a fixing member 73 and a fixing rack 74 that support the solar cell module 61, and screws or nails on the roof. The fixed rack 74 is fixed to the fixed rail 75 with screws or bolts, and the fixing member 73 is fixed to the fixed rail 75 with a fastening member 65 via a height adjusting mechanism described later. The solar cell module 61 is fixed to the fixing member 73 and the fixing rack 74 by fitting, screw fixing, and pinching fixing with a cover or a clasp. In this example, a description will be given using a structure in which the solar cell module 61 is fitted into the groove portion of the fixed rack 74 and then fixed to the fixing member 73 with screws.

  Next, details of the height adjustment mechanism will be described in detail. As shown in FIG. 16, a fixing portion 76 is provided on the eaves side of the fixed rail 75, and a long hole portion 77 that is a height adjusting mechanism is provided in the fixing member 73. This example will be described in more detail. As shown in FIG. 17, the fixing portion 76 has an eave side end portion of the fixing rail 75 bent upward, and a screw hole 78 for receiving a fastening member 65 such as a screw or bolt is provided there. In the other fixing member 73, a long hole portion 77 through which the fastening member 65 passes is opened so that the longitudinal direction comes up and down. Therefore, in the state assembled by fastening the fixing portion 76 and the fixing member 73 with the fastening member 65, the elongated hole portion 77 can move up and down in the loosened state, and the fixing member 73 is integrated. And the height of the solar cell module placed thereon can be changed. And if fastening is strengthened in arbitrary height positions, it will be fixed in that state.

  Specifically, as shown in FIG. 18A, in the standard position, the height to the surface of the solar cell module 61 of the photovoltaic power generation device S is the length of H1 in the figure, but the fastening member is loosened and the fastening member is loosened. When 73 is lifted, the height to the surface of the solar cell module 1 becomes longer by H2 as shown in FIG. On the other hand, when the fixing member 73 is pushed down, the height is shortened by H3 as shown in FIG.

  Next, a method for adjusting the heights of a plurality of solar cell modules arranged on the roof by the solar power generation device S using the above-described height adjusting mechanism will be described.

  The roof 64 of the house is a flat roof material such as a field board, and the field board is usually a wood called a plywood. The rigidity is low, the deflection due to its own weight, and the amount of deflection when a load such as a tile is mounted. Acts in the direction of worsening the flatness. A state in which such a roof shape is undulated is referred to as “non-land”, but when the photovoltaic power generation devices S (S1, S2) are arranged in such a place, as shown in FIG. Compared to the solar power generation device S1 installed on the roof surface, the solar power generation device S2 installed in a place where the roof is dented and inclined is inclined with the fixed rail 75a as a fulcrum, so the end is lifted upward As shown in the drawing, a height is generated between the solar power generation device S1 and the end thereof. When such a state is viewed as a roof, irregularities such as protrusions are visible on the roof surface, which impairs the beauty of the house. Such a symptom appears remarkably when a short rail is combined rather than a long rail.

  On the other hand, in order to eliminate such a step, for example, when the end portions of the solar power generation device S1 and the solar power generation device S2 are connected with metal fittings or the like to be adjusted in height, the solar cell modules are bent to both solar cell modules. Since not only the stress continues to be applied but also the pressing load is continuously applied to the fixed rail 75a, the margin for the positive pressure load is reduced. On the contrary, the fixed rail 75b is applied with a force in the pulling direction, so a negative pressure load due to wind or the like. The margin with respect to will decrease. The same can be said for a long rack.

  Therefore, as shown in FIG. 19B, the height adjustment mechanism is used to reduce the length between the fixed rail 75a and the fixed member 73, and to increase the length between the fixed rail 75b and the fixed member 73. For example, the step between the solar power generation device S1 and the solar power generation device S2 becomes small, and the surface of the solar cell module becomes continuous as shown in FIG. Since no stress is applied to any of these points, the resistance to the external pressure can be preserved, and the resistance of the entire photovoltaic power generation system can be maximized.

  In addition, by shortening the length of the support rail, which is a horizontal rack material, as short as the length of one solar cell module, it is possible to work safely during construction and improve work efficiency by making it easy to carry. In addition, since the minimum length of the loading platform can be shortened in truck transportation, the transportation cost can be reduced.

  The present invention has been described by taking a solar cell module as an example of a roof installation body, but is not limited thereto, and can be suitably applied to flat solar energy utilization devices such as a solar collector, The present invention can be appropriately modified and implemented without departing from the gist of the present invention.
