  However, in the structure of Patent Document 1, the water-side frame (32) and the water-side frame (33) are used. In the structure of Patent Document 2, the water-side frame (11) and the water-side frame (12) are used. Since the frame material has a complicated configuration, these frame materials are special, and an increase in cost is inevitable.

  Further, in the structure of Patent Document 3, the support frame 1 is not physically fixed in the structure of Patent Document 4 and the frame body 1 and the frame body 1 are not physically fixed. It is integrated by fixing the covers 11 and 3 that cover the lower end of the solar cell module, rainwater flowing down on the module is blocked, and dirt, dust, etc. contained in the rainwater easily accumulate. It was a thing. As a result, dirt adheres to the module surface, and the performance is lowered, and the water-stopping material in the frame part is easily deteriorated.

  Therefore, the present invention provides a solar cell module that can reliably and easily fix the underwater side end of the solar cell module integrally without causing an increase in cost due to the use of a special member (frame). The purpose is to propose the structure and installation method.

The present invention has been proposed in view of the above, and rail materials having support portions on which a solar cell module or an exterior material can be placed on the water side and the water side are arranged at predetermined intervals, and between the rail materials. In the solar cell module installation structure in which the solar cell module or the exterior material is laid on the solar cell module, the solar cell module is laid on at least one of the water side and the water side of the rail material, and is laid on the water side of the rail material. In the solar cell module, the back surface of the lower end is placed on the rail member, and the surface is held by an attachment member along the rail member. The attachment member is connected to the lower end of the solar cell module. It consists of a holding part that holds the surface of the part and a front part along the bottom end of the rail material, and is arranged at regular intervals in the longitudinal direction of the rail material, and a fixture is driven into the rail material from the front part At Leh The exterior material that integrates the material and the mounting member and is laid on the water side of the rail material has the rear surface on the water side placed on the rail material, and the molded part that is bent on the water side is the water of the rail material. It is related with the installation structure of the solar cell module characterized by being latched by the lower end part.
Note that “along” means a state before the attachment member is fixed by the fixture.

  Moreover, this invention also proposes the installation structure of the solar cell module characterized by the front-surface part being the inclined surface shape which inclines and descends under water in the said installation structure.

  The present invention also proposes a solar cell module installation structure characterized in that, in the installation structure, the rail member has a groove-like portion continuous in the length direction.

  Further, according to the present invention, rail members having support portions on which a solar cell module or an exterior material can be placed on the water side and the water side are arranged at predetermined intervals, and the solar cell module or the exterior material is provided between the rail materials. In the solar cell module installation method of laying solar cells, a first step of arranging rail members at a predetermined interval, a second step of laying solar cell modules or exterior materials between the arranged rail members, The mounting member comprising the front surface portion along the lower end portion of the battery module is disposed on the lower end portion of the rail material from above, and a fixing tool is driven from the front portion, so that the water of the disposed solar cell module At the lower end, the rail material and the mounting member are integrated, and the back surface of the exterior material on the lower side is placed on the upper end portion of the rail material. Third work to be locked to the bottom of the water When and it proposes also a method of installing a solar cell module which comprises a.

  The installation structure of the solar cell module of the present invention is such that the lower end of the solar cell module is integrally fixed by the rail material and the mounting member, and the rail material and the mounting member to be used are extremely simple. Since it is a simple member and does not require a special frame material as in the prior art (Patent Documents 1 and 2), the cost can be reduced. Moreover, since the cover material is not used as in the prior art (Patent Documents 3 and 4), the rainwater flowing down on the module is not dammed, and the soil, dust, etc. contained in the rainwater are not deposited and are negative. It is possible to reinforce the strength improvement during the pressure action and the displacement stop in the flow direction. Therefore, the module surface can be maintained beautifully, and performance degradation such as power generation efficiency is not caused. Moreover, since the solar cell module is integrated with the rail member by the mounting member, the solar cell module can be easily replaced by attaching and detaching the mounting member.

  In particular, when the front surface has an inclined surface shape that is inclined downward to the water side, the design is excellent, and the shadow formed on the lower solar cell module can be minimized. In addition, when the mounting member is formed of a light-transmitting material, the inclined front surface portion is excellent in daylighting, so when a double-sided light-receiving (power generation) type solar cell is used. Is preferred.

  In addition, when the rail material has a groove-like portion that is continuous in the length direction, even if rainwater may circulate to the back side of the solar cell module, Can flow down.

  In the solar cell module installation structure of the present invention, a rail material having a support portion on which a solar cell module or an exterior material can be placed on the water side and the water side is disposed at predetermined intervals in the flow direction. In the structure in which a solar cell module or an exterior material is laid in between, a solar cell module is laid on at least one of the water side and the water side of the rail material, and the solar cell module laid on the water side of the rail material is The back surface of the underwater end is placed on the rail material, and the surface thereof is held by an attachment member along the rail material, and the attachment member covers the surface of the underwater end portion of the solar cell module. It consists of a holding part to hold and a front part along the bottom end of the rail material, and is arranged at regular intervals with respect to the longitudinal direction of the rail material. Integration The exterior material laid on the water side of the rail material is such that the bottom surface of the water side is placed on the rail material and the molded part bent at the water side is locked to the water bottom end of the rail material. It is characterized by being.

The solar cell module used in the present invention only needs to be a panel made of a silicon-based, compound-based, organic-based solar cell, etc., and subjected to water sealing and waterproofing treatment at the periphery (small edge) as the module. However, it is preferable that there is no projection such as a frame at least in the direction intersecting the flow direction so as not to block rainwater flowing down the surface of the solar cell module. In order to increase the amount of power generation, a double-sided light reception (power generation) type solar cell may be used. In this case, a reflector may be interposed below the solar cell module. Further, the module may use a double-sided light-receiving cell that is reduced in size (for example, about half) in order to increase the versatility of the peripheral device.
And among the edges in the flow direction, the back surface of the water-side end portion is placed on the water-side support portion of the rail material, and the surface of the water-side end portion is a mounting member along the rail material. And is integrated (fixed) in a sandwiched manner from above and below.

The rail material used in the present invention has a water-side support part and a water-side support part that support an edge in the flow direction of the solar cell module or the exterior material, and a fixture is provided from the front part of the mounting member described later. Although it has a fixed portion to be driven in, its specific configuration and other configurations are not particularly limited, and may be any shape or configuration, even a single member or a plurality of members It may be configured by.
For example, regarding the water-side support portion and the water-side support portion, in the illustrated embodiment described later, since the solar cell module is adjacent in the flow direction, the water-side support portion and the water-side support portion are Although the level was formed in the level | step difference equivalent to the thickness of a solar cell module, it does not specifically limit.

Furthermore, it is desirable to form a groove-like portion between the water-side support portion and the water-side support portion as in the illustrated embodiment described later. Since this groove-like portion is continuous in the length direction, even if rainwater may circulate to the back side of the solar cell module, it is led from this groove-like portion to the drainage portion of the drainage member and allowed to flow downward. be able to.
Further, as shown in the illustrated embodiment described later, it is desirable to form a housing portion that is a groove-like space that opens upward, and to house the cable of the solar cell module in the housing portion. This cable housing part not only prevents cable entanglement, but also prevents sunlight from being blocked (forms a shadow on the module surface) when using a double-sided solar cell module. It also plays a role.

The rail material is desirably a long material having the same cross section in the length direction as in the illustrated embodiment described later. In this case, the solar cell module to be used can be appropriately shaped (cut) according to the length dimension in the carry direction, and any size solar cell module can be handled very easily.
Further, it is desirable that the rail member has a support piece that protrudes to the underwater side as in the illustrated embodiment described later, in addition to the support portion described above. In the rail material of this configuration, the underwater side edge of the solar cell module can be placed on the support piece, and rainwater or the like traveling on the surface of the solar cell module is surely placed on the solar cell module adjacent to the underwater side. Led to drainage.

The mounting members used in the present invention are arranged at regular intervals with respect to the longitudinal direction of the rail material, and a holding portion that holds the surface of the underwater side end portion of the solar cell module, and the rail material It may have a front part along the lower end of the water and may be constituted by a single member or a plurality of members.
Since the front portion also serves as a fixing portion for driving and fixing a fixing tool to a fixed portion provided at the lower end portion of the rail material, the front surface portion is substantially horizontal so that the fixing tool can be driven from the upper side or the lower water side. It is desirable that the shape or the inclined surface shape (an inclined surface shape inclined downward to the water side).
The shape of the front portion is not particularly limited. However, when the front portion has an inclined surface shape that is inclined downward to the water side, it is excellent in design and has a shadow formed on the lower solar cell module. Can be minimized. In addition, when the mounting member is formed of a light-transmitting material, the inclined front surface portion is superior to the front surface portion having the corners in terms of daylighting. It is suitable when using the solar cell.

At the upper end of the rail member, as shown in the illustrated embodiment to be described later, a discard plate may be disposed in the flow direction to support the left and right side ends of the solar cell module.
As this discard plate, it is desirable to use a standard material having the same cross section in the length direction as in the illustrated embodiment described later. In this case, the solar cell module to be used can be appropriately shaped (cut) according to the length in the flow direction of the solar cell module to be used, and any size solar cell module can be handled very easily.
In addition, it is desirable that this discard plate has a ridge portion at substantially the center, and water return portions on the left and right sides thereof, respectively, along the length direction as in the illustrated embodiment described later. In the discard plate having this configuration, when the joint cover is attached so as to cover the arrangement interval after the solar cell module is arranged, a ridge portion can be used as a place where the fixing tool is hit. Moreover, even if rainwater or the like enters the back side of the joint cover, the rainwater or the like can surely flow down to the underwater side at the water return portions formed on the left and right.

  When this discard plate is used, the water-side support part and the water-side support part of the rail material do not directly support the edge in the flow direction of the solar cell module. It will be supported via a plate.

Moreover, you may arrange | position so that a joint cover may be covered in the arrangement | positioning space | interval of the right and left of a solar cell module.
This joint cover covers the space between the left and right solar cell modules disposed on the discard plate, and is attached with screws or the like as shown in the illustrated embodiment described below. A bent shape is desirable. In this case, the joint cover can be slid from the underwater side and arranged at the interval between the left and right solar cell modules.
In addition, the side edge of the solar cell module may be directly fixed by a screw or the like, or may be sandwiched by the joint cover.

Further, the holding part of the fixing tool used in the present invention is not limited to the one that directly holds the surface of the underwater side end part of the solar cell module 1, and the holding tool having elasticity in at least the thickness direction. The surface of the lower edge of the solar cell module may be held via In other words, an elastic holding tool may be interposed between the holding part of the fixing tool and the surface of the lower end portion of the solar cell module.
This holder may be provided at one place or at two or more places.
In this way, when a holder having elasticity in the thickness direction is used, it can be easily recognized if there is a deficiency in the driving of the fixing tool, and repairs can be made as appropriate. For example, if there is no hindrance to the fixing tool even if the fixed portion of the second rail member is damaged, it is difficult to visually determine from the surface. It can be easily visually confirmed that the fixing tool has not been properly driven. Furthermore, this holder contributes to elimination of rattling.

  This holder may be made of a regular or irregular material (elastic material) having elasticity (rubber elasticity or spring elasticity) in the thickness direction, or it is not an elastic material but is formed into a piece material of a predetermined shape. In addition, the holder or the attachment member to be attached may be used for elastic fitting (engagement). In the case of the former, it is only necessary to attach the holder against the elasticity of the holder, and in the latter case, a dimension or shape in which a repulsive force acts on the fitting (engagement) portion of the holder or the attachment member. What is necessary is just to shape | mold in a bending shape and to fit (engage) elastically. Further, the attachment of the holding tool may be performed after the installation of the attachment member, or may be attached at the same time, or may be attached in advance to the attachment member, if it is before the fixing tool is driven.

  The installation structure of the solar cell module of the present invention composed of these members is constructed in the following first to third steps.

First, in the first step, the rail material is disposed substantially orthogonal to the flow direction. Although this rail material may be arranged directly on the base, it is arranged in a substantially orthogonal shape so that the end faces the drainage member arranged in the flow direction as in the illustrated embodiment described later. May be. In this case, even if rainwater or the like may circulate to the back side of the discard plate, the rainwater to be circulated can be guided to the drainage portion of the drainage member and allowed to flow downward.
The foundation refers to the object to which the solar cell module is to be fixed. In the case of a new installation, even if it is a casing constructed of light-weight steel such as a steel frame or C-type steel, or wood, the foundation such as heat insulation on the casing A material may be laid, or a concrete base may be used. Moreover, the roof surface of the existing roof or the base of the existing roof may be set as an attachment target, or the existing roof may be appropriately subjected to base processing.

  Next, in the second step, a solar cell module or an exterior material is laid between the arranged rail members, and the water-side support portion of the upper rail material and the water-side support portion of the lower rail material The water-side end and the water-side end of the solar cell module or the exterior material are supported so as to be placed.

Subsequently, in the third step, the mounting member is placed along the lower end of the rail material from above and the fixture is driven from the front surface, so that the rail material and The mounting member is integrated.
As a result, the lower end portion of the solar cell module is integrally fixed by the rail material and the mounting member.

In addition, when using the discard board of the said structure, what is necessary is just to implement the following processes after the said 1st process.
The upper edge of the discard plate is supported by the lower support portion of the installed rail material, and the lower edge of the discard plate is supported by the upper support portion of the rail material adjacent to the lower surface. Attach to make it. When the rail member is provided with the support piece protruding downward as described above, the space between the support piece and the underwater support portion is provided when the discard plate is disposed. It is only necessary that the water-side edge of the discard plate is inserted, and at least the water-side edge of the discard plate does not float and come off.

When the joint cover having the above-described configuration is used, the following steps may be performed after the third step.
It arrange | positions so that a joint cover may be covered in the arrangement | positioning space | interval of the right and left of the laid solar cell module. If the joint cover has a shape in which the flat underwater side is bent downward as described above, it can be easily arranged to the left and right at the intervals of the solar cell modules by sliding from the underwater side. can do. In addition, when the rail member is provided with a support piece that protrudes below the water as described above, the edge on the water side of the joint cover is inserted between the support piece and the discard plate (space). Therefore, at least the water-side edge of the joint cover does not float up and come off.

  In the solar cell module installation method of the present invention thus constructed, the first step of disposing the rail material, the second step of disposing the solar cell module, and the third step of disposing the mounting member. Since each process is also performed from the surface side, it can be applied very easily. In particular, in the third step, the operation of bringing the attachment member along the lower end of the rail material from above, and the operation of driving the fixture from the upper side or the upper side of the water can be performed very easily.

  And the installation structure of the solar cell module of the present invention to be constructed is such that the underwater side end portion of the solar cell module is integrally fixed by the rail material and the attachment member, and the rail material to be used is also attached. Since the member is also a very simple member and does not require a special frame material as in the prior art, the cost can be reduced. Moreover, since no cover material is used as in the prior art, the rainwater flowing down on the module is not blocked, and the soil and dust contained in the rainwater are not deposited, improving the strength and flow during negative pressure action. The misalignment stop can be reinforced. Therefore, the module surface can be maintained beautifully, and performance degradation such as power generation efficiency is not caused. Moreover, since the solar cell module is integrated with the rail member by the mounting member, the solar cell module can be easily replaced by attaching and detaching the mounting member.

In addition, sunlight reflected by the reflector 9 disposed on the lower side (back side) can also be received, and the terminal box 102 and the cable 101 protrude on the back side as shown in FIGS. 1 (a) and 1 (b). Although not shown in the figure, the edge (small edge) is water-stopped and waterproofed, and the frame material is not used in principle.

  The rail member 4 includes a water-side support portion 41 and a water-side support portion 42 that support the flow direction edge of the solar cell module 1 or the exterior material 7, and the front surface portion 62 of the mounting member 6 described later. It has a fixed portion 49 into which the fixing tool 6b is driven, and corresponds to a so-called horizontal rail, and is composed of a plurality of members including the rail material body 4 and the second rail material 4B.

Moreover, the rail material 4 in this 1st Example is the structure which has the support piece 43 which protrudes under water, and was made into the elongate material which has the same cross section in a length direction. Furthermore, the vertical piece-like leg portions 44, 44 extending downward on the water upper side and the water lower side, the grounding portions 45, 45 contacting the ground 8A at the lower ends of the leg portions 44, 44, and the length direction The extending groove-like portion 47 is provided between the water-side support portion 41 and the water-side support portion 42.
Of the legs 44, the legs 44 located on the water side are extended upward to form a housing portion 48 that is a groove-like space opened upward, and the solar cell module 1 of the solar cell module 1 is formed in the housing portion 48. The cable 101 located on the back side was accommodated, and the upper part thereof was covered with the covering material 4C.
In addition, an elastic material 46b is mounted on the back surface side of the support piece 43 in a groove that opens downward, and the water-side edge of the solar cell module 1 or the exterior material 7 is received by the water-side support portion 42. When they are supported, they contact each other between the elastic material 46a disposed above and the elastic material 46b disposed below, so that they are sandwiched from above and below and attached in a sandwiched manner by an elastic action.

Further, the second rail member 4B is attached to the support piece 43 with screws (screws 43b) from above, and fixed to the lower end of the second rail member 4B so as to be inclined downward on the water side. A portion 49 is formed.
On the surface of the fixed portion 49, a recess 491 is provided in which the tip of a fixture 6b for fixing the mounting member 6 to be described later contacts. Note that the lower end of the inclined fixed portion 49 is folded back to the upper side of the water (return piece 492) and extends in a substantially square shape.
The second rail member 4B has a raised portion on the water side from the center, and a cushion material 4d for receiving and supporting the back surface of the solar cell module 1 is fixed to the upper surface of the raised portion.

  The installation structure of the solar cell module 1 of the present invention constructed by such members is such that the lower end of the solar cell module 1 is integrally fixed by the rail material 4 and the mounting member 6. Since the rail material 4 and the mounting member 6 to be used are extremely simple members and no special frame material is required as in the prior art, the cost can be reduced. Moreover, since no cover material is used as in the prior art, the rainwater flowing down on the module 1 is not blocked, and the soil and dust contained in the rainwater are not deposited, and the strength is improved during negative pressure action. The misalignment stop in the flow direction can be reinforced. Therefore, the module surface can be maintained beautifully, and performance degradation such as power generation efficiency is not caused. Moreover, since the solar cell module 1 is integrated with the rail member 4 by the mounting member 6, the solar cell module 1 can be easily replaced by detaching the mounting member 6.

Moreover, in this 1st Example, since the rail material 4 has the support piece 43 which protrudes under water, and has mounted the underwater side edge of the solar cell module 1 on this support piece 43, Rainwater or the like traveling on the surface of the solar cell module 1 is reliably guided and drained onto the solar cell module 1 adjacent to the underwater side.
Further, in the first embodiment, since the housing portion 48 is provided in the rail member 4 so as to accommodate the cable 101 of the solar cell module 1, not only the cable 101 is entangled but also a double-sided light receiving type. When a solar cell module is used, it also plays a role of preventing sunlight from being blocked (forming a shadow on the module surface).
In addition, the front and back of the solar cell (double-sided light receiving cell) 10 can be effectively used for power generation, and a larger amount of power can be generated with the same installation area as that of a normal solar cell module having a single-sided light-receiving cell. I can expect. Furthermore, when a reflective material such as a metal is disposed on the entire surface of the base surface, the workability as the reflective material or the reflective portion is facilitated, the cost is reduced, and the entire surface of the base surface is made of metal. Since it is covered, it has a structure with excellent fireproof performance.

FIG. 3 shows a connecting portion in which a general side wall exterior structure is disposed on the water upper side and water lower side of the solar cell module 1 in the first embodiment, and at least the length dimension in the flow direction is the solar cell. By using the horizontal covering material 7 substantially equal to the module 1, the roof surface is constructed by combining the horizontal covering material 7 in the same manner as the solar cell module 1.
In addition, the rail member 4 having the above-described configuration is used regardless of which of the solar cell module 1 and the side covering member 7 is on the water side.

The lateral covering material 7 has a configuration in which an eaves-side molded portion 72 is formed at the edge of the underwater side of the substantially flat face plate portion 71, and a ridge-side molded portion 73 is formed at the edge of the waterside. The eaves side molding portion 72 and the ridge side molding portion 73 are configured to engage with each other at a connection portion (not shown).
The eaves side molding part 72 bends the eaves edge of the face plate part 71 downward in a substantially vertical shape, bends the lower end thereof toward the ridge side, and then bends it upward in a substantially square shape. The structure was folded back to the side.
The ridge-side molding part 73 is configured such that an end edge extending from the face plate part 71 is bent and bent back to the surface side, and the eaves end is bent downward.
In addition, as a metal material material of this side covering material 7, typically about 0.4 to 1.6 mm of galvanized steel sheet, galvanium steel sheet or other rust-proof steel sheet, special steel, non-ferrous metal, stainless steel A steel plate, a weather-resistant steel plate, a copper plate, an aluminum alloy plate, a lead plate, a zinc plate, a titanium plate, and the like are exemplified, but the invention is not particularly limited thereto. These are supplied in an almost coiled form.
Further, a back-up material 7B such as a polyethylene foam or a glass wool sheet is attached to the back side of the horizontal covering material 7 for reasons of preventing condensation, soundproofing, and fireproofing.

Then, the connection between the solar cell module 1 and the lateral covering material 7 shown in FIGS. 3 (a) and 3 (b) is as described above with respect to the attachment of the solar cell module 1 as described above. However, with respect to the attachment of the side covering material 7, the rail material 4 is attached as a hanging member as will be described below.
As shown in FIG. 3 (a), the eaves-side molded portion 72 of the side covering material 7 is attached to the lower end (return piece 492) of the fixed portion 49 of the rail material 4 (second rail material 4B). be able to.
As shown in FIG. 3 (b), the ridge-side molded portion 73 of the side facing exterior material 7 is placed on the elastic material 46a attached to the underwater support portion 42 of the rail material 4 (second rail material 4B). The rail member 4 (second rail member 4B) and the attachment member 6 can be pressed and held from the surface side.

The installation structure of the solar cell module 1 ′ of the second embodiment shown in FIGS. 4 and 5 is the same as that of the rail member 4, the attachment member 6, the fixture 6 b, etc. for receiving and supporting the solar cell module 1 ′. Although it is the same as that of an Example, it is an example from which the structure of the base | substrate part which arrange | positions the rail material 4 differs.
The solar cell module 1 ′ used in the second embodiment is formed by forming a substantially rectangular solar cell (single-sided light receiving cell) 10 with multiple faces as shown in FIG. 4 (d) and FIG. However, the edge (small edge) is water-stopped and waterproofed, and the frame material is not used in principle.
Further, in the second embodiment (the process of FIG. 4C described later), the left and right sides of the solar cell modules 1 ′ and 1 ′ are arranged by disposing a discard plate 3 on the upper end of the rail member 4 in the flow direction. It was made to support the side edge.
This discard board 3 is a structure which has the protruding part 31 in the approximate center, and the water return part 32 of several strip | stripes on the right and left so that it may each follow a length direction, and has the same cross section in a length direction. A material was used.

  Hereinafter, the construction procedure of the installation structure of the solar cell module 1 according to the second embodiment will be described with reference to FIGS.

  First, as shown in FIG. 4A, prior to the first step, the drainage member 2 was disposed on the base 8A (not shown) along the flow direction. The drainage member 2 has a configuration in which the upper ends of the side surfaces 22 and 22 of which the left and right side edges of the substantially flat bottom surface 21 are inclined are bent inward in a substantially horizontal shape to form receiving portions 23 and 23. It is a continuous material. The bottom surface 21 of the drainage member 2 is the bottom surface of the drainage part, and is hereinafter referred to as a drainage part.

In the first step, the rail member (main body) 4 having the above-described configuration is disposed substantially orthogonally on the drainage member 2 disposed as shown in FIG. 4B.
The rail member 4 is disposed in such a manner that the leg portions 44 and 44 are partially removed in advance before disposition so that the upper portion of the leg portions 44 and 44 faces the drainage portion 21 of the drainage member 2.
In addition, the covering material 4C is already mounted above the accommodating portion 48 provided in the rail material 4, but since the covering material 4C is formed of a resin molded body having elasticity, it can be easily attached and detached. The cable 101 (not shown) can be attached after being removed and accommodated in the accommodating portion 48.

Next, as shown in FIG. 4 (c), the water-side support portion 42 of the rail member 4 attached in the first step receives and supports the water-side edge of the discard plate 3 having the above-described configuration, It attaches so that the water-side edge part of the discard board 3 may be received and supported by the water-side support part 41 of the rail material 4 adjacent to the lower side.
Since the rail member 4 of the first embodiment is provided with the support piece 43 protruding downward as described above, the water-side edge of the discard plate 3 is connected to the support piece 43 and the underwater side. What is necessary is just to attach in the insertion form between the support parts 42 (space), and it attaches so that the edge of the lower side of the discard board 3 may be bridged over the upper surface of the water-side support part 41, and the upper surface of the support piece 43. As described above, the rail member 4 is composed of the main body 4 and the second rail member 4B. At this time, the second rail member 4B is loosely fitted on the surface of the support piece 43. As described above, it is fixed to the support piece 43 by screws as described above.

Subsequently, in the second step, as shown in FIG. 4D, the solar cell module 1 ′ is laid between the rail members 4 and 4 attached in the first step, and the water of the rail member 4 on the upper stage side is laid. The lower side support part 42 and the upper side support part 41 of the rail material 4 on the lower stage side are supported so that the upper side end part and the lower side end part of the solar cell module 1 ′ are placed. At this time, since the discard plate 3 is provided as described above, the end of the solar cell module 1 ′ in the length direction is supported.
In the illustrated embodiment, as described above, the elastic members 46a and 46b can be attached to the rail member 4, and the water-side edge of the solar cell module 1 'is attached between the elastic members 46a and 46b. The side edge is sandwiched from above and below and attached in a sandwiched manner by an elastic action.
Further, as described above, the second rail member 4B is fixed to the surface of the support piece 43 of the rail member 4, and the cushion member 4c is fixed on the second rail member 4B. The underwater side edge of 'is supported by the overwater side support portion 41 of the rail member 4 via the overlying edge of the discard plate 3, and the underwater side edge is further connected to the second rail member 4B. It will be supported by the cushion material 4c.

Furthermore, in the third step, the mounting member 6 having the above-described configuration is superposed along the lower end of the rail member 4 from above, and the fixture 6b is attached from above the lower side to the front portion 62 (and the back side thereof). By driving into the fixed portion 49), the rail member 4 and the attachment member 6 are integrated with the water-side end portion of the solar cell module 1 'disposed.
The attachment member 6 is attached in such a manner that the holding portion 61 is placed in a superposed manner so as to be placed on the upper surface of the lower end portion of the solar cell module 1 ′, and the rail material 4 (second rail material 4B) is covered. Since the fixing portion 49 may be disposed so as to cover the front surface portion 62 from above, it can be implemented very easily. Further, as described above, the fixing tool 6b can be driven in very easily because the tip of the fixing tool 6b is brought into contact with the recess 621 and driven from above the water side.
As a result, the front surface portion 62 of the mounting member 6 and the fixed portion 49 of the rail material 4 (second rail material 4B) are integrated in a superposed manner, and the rail material is attached to the lower end of the solar cell module 1 ′. 4 and the attachment member 6 are fixed integrally.

  Thereafter, in the illustrated embodiment (FIG. 5), the joint cover 5 having the above-described configuration is disposed so as to cover the left and right arrangement intervals of the solar cell modules 1 ′ and 1 ′ attached in the third step. In the first embodiment, as described above, the raised plate 31 is provided substantially at the center and the water return portions 32 are provided on the left and right sides of the discard plate 3 along the length direction, respectively. The joint cover 5 can be disposed to fix the fixing tool 5b such as a screw against the raised portion 31.

  In the installation method of the solar cell module 1 ′ of the present invention thus constructed, the mounting member 6 is used in both the first step of disposing the rail material 4 and the second step of disposing the solar cell module 1 ′. The third step of disposing and fixing the fixing tool 6b can be performed very easily from the surface side.

Furthermore, since the rail member 4 and the scraper plate 3 have the same cross section in the length direction as described above, the rail member 4 according to the length dimension in the flow direction of the solar cell module 1 to be used. Can be appropriately shaped (cut), and the length of the discard plate 3 can be appropriately shaped (cut) according to the length dimension of the solar cell module 1 ′ used in the direction of the carry. Any size solar cell module can be handled very easily.
In addition, since the rail member 4 of the illustrated embodiment is provided with the groove portion 47 between the water-side and water-side support portions 41, 42, rainwater may wrap around the back side of the solar cell module 1. Even if it is possible, it can lead to the drainage part 21 of the drainage member 2 from the groove-shaped part 47 of the rail material 4, and can be made to flow down under water.

Further, in the operation of attaching the discard plate 3 in the second step, the edge on the water side may be attached in an insertion shape between the support piece 43 and the water side support part 42 (space). Since it is only necessary to attach the lower edge to the upper surface of the water-side support portion 41 and the upper surface of the support piece 43, the workability is excellent, and at least the water-side side of the discard plate 3 The lifting of the edge is prevented by the support piece 43.
Moreover, in this 1st Example, since the protruding part 31 was provided in the approximate center of the discard board 3, and the water return part 32 was provided in the left and right, respectively so that a length direction may be followed, the fixation which fixes the joint cover 5 is fixed. The tool 5b can be struck against the raised portion 31, and even if rainwater or the like enters the back side of the joint cover 5, the water return portion 32 can surely cause rainwater or the like to flow down.

In the third to sixth embodiments shown in FIGS. 6A to 6D, the rail members 4III to 4VI are each constituted by a single member, and the holding portions 61 of the mounting members 6III to 6VI and the solar cell module, respectively. A holding tool 6c having elasticity in the thickness direction is interposed between the surface and the surface of the underwater end portion of 1 and integrated.
In addition, the drainage member 2 and the drainage part 21 are the same elongate materials as the said 2nd Example. Although not shown, the configuration below the solar cell module 1 and the rail members 4III to 4VI may be the same as that of the first embodiment or the second embodiment.

  The holder 6c of the illustrated embodiment is a rubber-shaped fixed shape (a shape having a substantially wedge-shaped insertion part), and this holder 6c is arranged on the back side of each holding part 61 of the mounting members 6III to 6VI. In the installed state, the solar cell module 1 is attached so as to cover the surface of the underwater side end portion, and in this state, the fixing member 6b is driven in from above or under the underwater side to fix the attachment members 6III to 6VI.

The attachment member 6III in the third embodiment of FIG. 6A and the attachment member 6IV in the fourth embodiment of FIG. 6B are both substantially M-shaped, and the fixture 6b is driven in a substantially vertical shape. It is fixed to the rail materials 4III and 4IV.
The difference between the two embodiments is that the length of the substantially horizontal horizontal piece for fixing the fixture 6b is slightly longer in the latter, and the lower end of the fixture 6b is located below the elastic material 6b, Even if there is a difference in whether it is located on the lower side, and rainwater may enter the back side of the mounting members 6III and 6IV through the fixture 6b, in the third embodiment, the solar cell on the lower side is exclusively used. It can be led on the module 1 and flowed down to the water side. In the fourth embodiment, it is led to the groove part 47 and led from the groove part 47 to the drain part 21 of the drainage member 2 to flow down to the water side. be able to.
The rail members 4III and 4IV in the third and fourth embodiments are made of a single member as described above, and in the first embodiment in which the fixture 6b is driven, there is a portion corresponding to the fixed portion 49. The reference numeral is not added except that it is substantially in the form of a horizontal piece, but the groove-like space that opens upward corresponding to the accommodating portion 48, the cushion material 4 d that supports the back surface of the solar cell module 1, and the solar cell module 1 Elastic members 46a and 46b that hold the water-side edge in a sandwiched manner are also provided.

Both the mounting member 6V in the fifth embodiment of FIG. 6 (c) and the mounting member 6VI in the sixth embodiment of FIG. 6 (d) have inclined portions 63 ′ and 63 ″ into which the fixture 6b is driven, Since the fixed portions 49 'and 49 "for supporting the inclined portions 63' and 63" are also formed on the rail members 4V and 4VI in an inclined shape, the holding member 6c is compressed, so that it is inclined even when compressed from above. Since the driving operation can be performed while the portions 63 ′ and 63 ″ are in contact with the fixed portions 49 ′ and 49 ″ while being shifted downward, the fixing tool 6b can be driven stably at an appropriate position.
The difference between the two embodiments is that the mounting member 6VI of the sixth embodiment is provided with a protruding portion 64 that protrudes in the shape of a character to the water side directly above the driving portion 63 "of the fixture 6b. The distance between 63 ″ and the fixed portion 49 ″ is long, and the fixture 6b can be driven into an appropriate position more stably.

  And in these 3rd-6th Example, since the holding tool 6c which has elasticity in the thickness direction was used, it can be easily recognized when there is a deficiency in the driving of the fixing tool 6b. It can be repaired. Moreover, the holder 6c in these 3rd-6th Example contributes also to elimination of rattling. Furthermore, in the state where the attachment members 6III to 6VI are arranged with the holder 6c interposed, the attachment members 6III to 6VI are in a state of floating from the solar cell module 1 or the rail members 4III to 4VI. Since the float is eliminated, it also serves as a guide for driving work.
