Description

  The present invention relates to a building material integrated tile type solar cell module and a roof mounting structure thereof.

  Conventional tile-type solar cell modules (hereinafter simply referred to as tile-type modules) are required to withstand wind loads (load weight) corresponding to the blow-up due to the requirements as solar cell modules. For this reason, in ordinary roof tiles, only the roof tiles are fixed to the roof rails with screws. However, roof tile modules have a structure that can withstand the load by hooking the modules together (Patent Document). 1).

JP 2004-263544 A

In the conventional tile-shaped module, an “L” -shaped engaging portion is provided on the eave-side frame, and a “7” -shaped engaging portion is provided on the ridge-side frame, and these engaging portions are engaged. Was taken. More specifically, the eaves side engaging portion protrudes toward the ridge side from a vertical surface that hangs vertically and a lower end of the vertical surface with respect to the back surface (surface opposite to the light receiving surface) of the solar cell panel. The engaging portion on the ridge side is composed of a vertical surface that stands vertically with respect to the light receiving surface of the solar cell panel and a horizontal surface that protrudes from the upper end of the vertical surface to the eaves side. This method has the following two problems.
(1) The tile-shaped module is rolled from the eaves side, but it cannot be engaged unless the module is pulled up from the bottom. For this reason, if the hand is released from the module while it is being pulled up, the module may slide down to the eaves side. Usually, the module is once pulled up from the lower module, and thus glass (particularly, AR (Anti-Reflection) coated glass having an antireflection film formed on the outermost surface) may be damaged.
(2) Usually, even if the roof gradient changes, the interval between the tiles will not change, but sometimes the interval between the tiles may change for each roof gradient. In this case, the working dimensions of the tiles (surface dimensions excluding the overlapping part of the tiles) differ depending on the roof slope, but the conventional engagement method cannot cope with different working dimensions, and the working dimensions. It was necessary to take measures to change the shape of the frame every time (every roof slope).

  The present invention has been made in view of the above problems, and is a roof tile that has high work safety, can be easily constructed without scratching the glass, and can accommodate different working dimensions without changing the frame shape. An object is to provide a roof mounting structure for a solar cell module and a tile solar cell module.

  In order to solve the above-described problems, the present invention is a building material-integrated tile-type solar cell module, which is located on the roof eave side when the tile-type solar cell module is installed on the roof, and An eaves-side module frame having a side engagement portion, and a ridge-side engagement portion that is located on the ridge side of the roof and engages with the eave-side engagement portion when the tile-type solar cell module is installed on the roof The eaves-side engaging portion and the ridge-side engaging portion are connected to the eave-side engaging portion from the roof ridge side with respect to the ridge-side engaging portion. It is characterized by a structure that is engaged so as to be inserted to the side.

  The tile-type solar cell module of the present invention is configured to engage the eaves-side engaging portion with the ridge-side engaging portion so as to be inserted from the ridge side of the roof to the eave side. In addition, even if the operator releases his / her hand from the tile-type solar cell module, the engagement between the ridge-side engagement portion and the eaves-side engagement portion occurs, and there is no possibility that the tile-type solar cell module slides down and falls. The safety in the above work can be improved.

  Also, there is a construction method for pulling up the tile-type solar cell module from the bottom to the top by engaging the eaves side engaging part with the eaves side engaging part from the ridge side of the roof to the eaves side. I can't take it. For this reason, it can prevent that the glass of the light-receiving surface of a solar cell panel is damaged.

  Furthermore, the other tile type solar cell module of the present invention uses a module frame having the same shape on both the eaves side and the building side with the direction of the water flow direction reversed, so that the eaves side module frame and the building side module frame are used. And the cost of the tile-type solar cell module can be reduced.

[Embodiment 1]
Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

  FIG. 1 is a plan view showing a schematic configuration of a tile-type module (tile-type solar cell module) 1 according to the first embodiment. The tile-shaped module 1 includes a rectangular solar cell panel 2 that photoelectrically converts sunlight and a frame 3 that holds the solar cell panel 2 by framing it. The frame 3 is composed of four module frames attached to each of the four sides of the solar cell module. In the tile-shaped module 1, the eaves-side module frame 31 attached to the eave side and the ridge-side module frame 32 attached to the ridge side have different shapes on the two sides facing along the water flow direction of the roof.

  For example, the solar cell panel 2 sandwiches a solar cell formed by sequentially laminating a transparent electrode film, a photoelectric conversion layer (semiconductor layer), and a back electrode film between two glass plates, and the end of each glass plate is sandwiched between them. It is sealed. If it demonstrates in detail about this solar cell panel 2, a transparent electrode, the photoelectric converting layer which consists of a semiconductor layer, and a back surface electrode layer will be laminated | stacked in this order on the glass substrate which is a translucent board | substrate, and a photovoltaic cell will be carried out. The transparent glass substrate which is a protective plate is bonded to the back electrode layer side, and the space between the glass substrates is sealed. Alternatively, a solar battery cell sandwiched between one glass plate and a protective layer (back sheet) may be sealed.

  FIG. 2 is an enlarged cross-sectional view showing the structure of the eaves side end of the roof tile module 1. The eaves-side module frame 31 is made of, for example, an aluminum material, and the cross-sectional shape perpendicular to the longitudinal direction is the same at any location. Moreover, the said cross section of the eaves-side module frame 31 is comprised from the 1st thru | or 6th surface 31a-31f, as shown in FIG.

  The first surface 31a and the second surface 31b are orthogonal to each other, and are formed so that the first surface 31a protrudes rearward (toward the building) from the middle of the second surface 31b. The third surface 31c is formed by bending backward from the lower end of the second surface 31b. The fourth surface 31d is formed by being bent obliquely rearward from the rear end (ridge side) of the first surface 31a. The fifth surface 31e is formed by bending downward from the rear end of the fourth surface 31d. The sixth surface 31f is formed by bending forward (toward the eaves side) from the lower end of the fifth surface 31e. The fifth and sixth surfaces 31e and 31f form a substantially “L” shaped eaves side engaging portion 311 formed by these two surfaces. More specifically, the eaves side engaging portion 311 protrudes toward the eaves side from a vertical surface that hangs perpendicularly to the back surface (surface opposite to the light receiving surface) of the solar cell panel 2 and the lower end of the vertical surface. And a horizontal plane. In this example, the fifth surface 31e corresponds to the vertical surface, and the sixth surface 31f corresponds to the horizontal surface.

  The solar cell panel 2 is in contact with a part of the first surface 31a and the second surface 31b (portion above the first surface 31a) and is adhered to these surfaces with an adhesive or the like. . The eaves side module frame 31 is fixed to the solar cell panel 2 by this adhesion. In the configuration of FIG. 2, the back surface (surface opposite to the light receiving surface) of the solar cell panel 2 is a back sheet 2a.

  In addition, the cross-sectional structure of the eaves side module frame 31 shown in FIG. 2 is an example to the last, and this invention is not limited to this structure. For example, the fifth surface 31 e is not necessarily perpendicular to the light receiving surface of the solar cell panel 2, and the sixth surface 31 f is not necessarily horizontal to the light receiving surface of the solar cell panel 2. The modification of the cross-sectional structure of the eaves-side module frame 31 is shown in FIGS. The cross-sectional structure of the eaves-side module frame 31 illustrated in FIG. 2 has an advantage that it smoothly engages with a third surface 32c of the ridge-side module frame 32 described later.

  FIG. 4 is an enlarged cross-sectional view showing the configuration of the ridge side end of the roof tile module 1. The ridge-side module frame 32 is made of, for example, an aluminum material, and the cross-sectional shape perpendicular to the longitudinal direction is the same at any location. Moreover, the said cross section of the ridge side module frame 32 is comprised from the 1st thru | or 6th surface 32a-32f, as shown in FIG.

  The first surface 32a and the second surface 32b are orthogonal to each other, and are formed so that the second surface 32b is erected upward from the rear end of the first surface 32a. The third surface 32c is formed by bending backward from the upper end of the second surface 32b. The fourth surface 32d is formed by being bent obliquely rearward from the tip (eave side) of the first surface 32a. The fifth surface 32e is formed by bending backward from the lower end of the fourth surface 32d. The sixth surface 32f is formed to protrude downward near the rear end of the fifth surface 32e.

  The solar cell panel 2 is in contact with lower portions of the first surface 32a and the second surface 32b, and is bonded to these surfaces with an adhesive or the like. By this bonding, the ridge-side module frame 32 is fixed to the solar cell panel 2. Further, the upper part of the second surface 32b protrudes above the light receiving surface of the solar cell panel 2, and the upper part of the second surface 32b and the third surface 32c are substantially formed by these two surfaces. A ridge side engaging portion 321 having an “inverted L” shape is formed. More specifically, the ridge-side engaging portion 321 is composed of a vertical surface that stands vertically with respect to the light receiving surface of the solar cell panel 2 and a horizontal surface that protrudes toward the ridge side from the upper end of the vertical surface. . In this example, the second surface 32b corresponds to the vertical surface, and the third surface 32c corresponds to the horizontal surface.

  Note that the cross-sectional structure of the ridge-side module frame 32 shown in FIG. 4 is merely an example, and the present invention is not limited to this structure. For example, the second surface 32 b is not necessarily perpendicular to the light receiving surface of the solar cell panel 2, and the third surface 32 c is not necessarily horizontal to the light receiving surface of the solar cell panel 2.

  Next, the roof mounting structure of the tile-shaped module 1 will be described with reference to FIG. FIG. 5 illustrates a roof mounting structure using the eaves-side module frame 31 and the ridge-side module frame 32 when the two tile-shaped modules 1 are arranged along the water flow direction A of the roof.

  On the roof base plate 100 to which the tile-shaped module 1 is attached, tile rails 101 are arranged at a predetermined interval, and the tile-shaped module 1 is bridged and fixed between these tile rails 101. The tile-shaped module 1 is rolled in the order from the roof eave side to the ridge side, and the two tile-shaped modules 1 arranged along the water flow direction A of the roof are described here. For convenience, the module disposed on the eave side is referred to as a tile-shaped module (eave-side tile-shaped module) 1A, and the module disposed on the ridge-side is referred to as a tile-shaped module (ridge-side tile-shaped module) 1B. In this case, the eave-side tile-shaped module 1A is first sown, and the ridge-side tile-shaped module 1B is sown over it.

  First, the ridge-side module frame 32 of the eave-side tile-shaped module 1A is placed on the roof rail 101 and fixed. Specifically, the fifth surface 32e of the ridge-side module frame 32 is fastened and fixed onto the roof bar 101 with a wood screw 102 or the like. At this time, the ridge-side module frame 32 may be positioned by hooking the sixth surface 32f to the side surface of the roof tile 101.

  Next, while placing the third surface 31c of the eaves-side module frame 31 in the ridge-side tile-shaped module 1B on the solar cell panel 2 (light-receiving surface side) of the eave-side tile-shaped module 1A, the tile-shaped module 1B is mounted. By moving from the ridge side toward the eave side (that is, toward the downstream side in the water flow direction A), the ridge side engagement portion 321 of the ridge side module frame 32 and the eave side module frame 31 are engaged. The part 311 is engaged. Specifically, the sixth surface 31 f of the eaves-side module frame 31 is inserted under the third surface 32 c of the ridge-side module frame 32. By such engagement between the ridge-side engaging portion 321 and the eaves-side engaging portion 311, the roof tile-type module 1 can withstand a corresponding wind load (load weight).

  After the ridge side engaging portion 321 and the eaves side engaging portion 311 are engaged as described above, the ridge side module frame 32 of the ridge side tile-type module 1B is placed on the roof tile 101. The fifth surface 32e of the ridge-side module frame 32 is fastened and fixed on the roof bar 101 with a wood screw 102 or the like, whereby the ridge-side tile-type module 1B is fixed to the roof. Thereafter, the roof tile module 1 can be sequentially attached along the water flow direction A by repeating the above operation.

  The tile-shaped modules 1 are arranged side by side not only in the water flow direction A but also in the horizontal direction (direction perpendicular to the water flow direction A). Thus, the tile-shaped modules 1 and 1 arranged in the horizontal direction are also connected by the frame 3. However, since this connection structure can use a well-known structure, detailed description is omitted here.

  When roofing using the tile-type module 1 of the present invention, the tile-type module 1 is not necessarily used for the entire roof, and the tile-type module 1 and a normal tile may be used in combination. 6 and 7 are cross-sectional views showing a roof mounting structure using the tile-type module 1 and the ordinary roof tile 200. FIG. FIG. 6 shows the case where the tile 200 is arranged on the eave side and the tile module 1 is arranged on the ridge side, and FIG. 7 shows the case where the tile module 1 is arranged on the eave side and the tile 200 is arranged on the ridge side. Yes.

  In the roof mounting structure shown in FIG. 6, the ridge side end portion of the tile 200 is fastened and fixed onto the roof tile 101 with a wood screw 103 or the like. Further, a connecting member 201 is attached and fixed to a predetermined location near the ridge side end on the top surface of the roof tile 200 by screws. As shown in FIG. 6, the cross section of the connecting member 201 is composed of first to third surfaces 201a to 201c. The first surface 201 a is in contact with the upper surface of the roof tile 200 and screwed. The second surface 201b is formed so as to stand upward from the rear end of the first surface 201a. The third surface 201c is formed by bending backward from the upper end of the second surface 201b.

  With respect to the roof tile 200 to which the connecting member 201 is attached, the roof tile module 1 disposed on the ridge side of the roof tile module 1 is placed on the top surface of the roof tile 200 while the third surface 31c of the eaves-side module frame 31 is placed. By moving toward the eave side from the ridge side (that is, toward the downstream side in the water flow direction A), the eave side engaging portion 311 of the eave side module frame 31 and the connection member 201 are engaged.

  In the roof mounting structure shown in FIG. 7, the connection member 202 is fixedly attached to a predetermined location near the eaves side end portion of the bottom surface of the tile 200 by screws. As shown in FIG. 7, the cross section of the connecting member 202 includes first to third surfaces 202 a to 202 c. The first surface 202a is in contact with the bottom surface of the roof tile 200 and screwed. The second surface 202b is formed so as to stand downward from the front end of the first surface 201a. The third surface 202c is formed by bending forward from the lower end of the second surface 201b.

  The roof tile 200, to which the connecting member 202 is attached, is moved from the ridge side toward the eaves side (that is, toward the downstream side in the water flow direction A) with respect to the roof tile module 1 arranged on the eaves side. Thus, the connecting member 202 and the ridge side engaging portion 321 of the ridge side module frame 32 are engaged.

  As described above, the roof tile-type module 1 according to the first embodiment engages the roof-side engagement portion 321 of the roof-side tile-shaped module 1B with the roof-side engagement portion 321 of the roof-side roof tile-shaped module 1A. In combining, the tile-shaped module 1B is moved from the building side toward the eaves side. That is, the eaves side engaging portion 311 is engaged with the ridge side engaging portion 321 so as to be inserted from the ridge side.

  According to this configuration, even if the operator releases his hand from the roof tile module 1B during the engagement operation, the ridge side engagement portion 321 and the eaves side engagement portion 311 are engaged, and the roof tile shape There is no fear that the module 1B slides down and falls. That is, the safety in the above work is improved. Further, this effect can be obtained even when the roof tile 200 and the roof tile module 1 are engaged as described with reference to FIGS.

  Furthermore, in the tile-type module 1 according to the first embodiment, a construction method is employed in which the ridge-side tile-type module 1B is lifted upward from below with respect to the eave-side tile-type module 1A as in the prior art. Absent. For this reason, it can prevent that the glass of the light-receiving surface of the solar cell panel 2 of the tile-shaped module 1A is damaged. More specifically, it is possible to prevent the exposed surface (the surface on which the tile-shaped module 1B is not placed) of the glass of the solar cell panel 2 (particularly when AR (Anti-Reflection) coated glass is used) from being scratched. In addition, in the part where the tile-shaped module 1B is placed on the solar cell panel 2 of the tile-shaped module 1A, even if the glass is scratched, it does not affect the amount of light incident on the solar cell. No problem.

  As a modification of the first embodiment, as shown in FIG. 8, the eaves side module frame 33 is used instead of the eaves side module frame 31, so that the light receiving surface of the eave side tile module 1 </ b> A is on the ridge side. It is also possible to prevent the tile-shaped modules 1B from overlapping completely. The cross section of the eaves-side module frame 33 is composed of first to fourth surfaces 33a to 33d as shown in FIG. In the eaves-side module frame 33, an eaves-side engagement portion 331 is formed by the third surface 33c (vertical surface) and the fourth surface 33d (horizontal plane).

  When the eaves-side module frame 33 is used, the eaves-side engagement portion 331 can be disposed further forward (eave side) than the eaves-side engagement portion 311 in the eaves-side module frame 31. For this reason, when the ridge side engaging part 321 and the eaves side engaging part 331 are engaged, the ridge side tile module 1B does not overlap the light receiving surface of the eaves side tile module 1A. In this case, it is possible to completely prevent the glass on the light receiving surface of the solar cell panel 2 of the roof tile module 1A from being scratched.

  Moreover, in the structure shown to FIG. 4 and FIG. 5 of this Embodiment, the structure which the ridge side module frame 32 does not cover the solar cell panel 2 in 1 A of tile-shaped modules is illustrated. However, the present invention is not limited to this, and as shown in FIG. 9, a part of the ridge-side module frame 32 may cover the light-receiving surface of the ridge-side peripheral portion of the solar cell panel 2. In that case, the third surface 31c of the eaves-side module frame 31 in the roof tile-type module 1B is placed on the portion of the ridge-side module frame 32 that covers the light receiving surface of the solar cell panel 2.

[Embodiment 2]
In the second embodiment, when the interval of the tile rails 101 (the interval in the roof gradient direction) changes according to the roof gradient, the tile-shaped module of the present invention can cope with different working dimensions without changing the shape of the frame. Explain that there is.

  FIGS. 10 and 11 respectively show a roof mounting structure of the tile-type module 1 on a four-dimensional gradient roof and a roof mounting structure of the tile-shaped module 1 on a five-dimensional gradient roof. Here, the gap between the roof tiles 101 is set wider for the five-slope roof than for the four-slope roof. That is, the relationship between the interval L1 between the tile bars 101 in FIG. 10 and the interval L2 between the tile bars 101 in FIG. 11 is L1 <L2.

  The roof mounting structure of the tile module 1 in FIGS. 10 and 11 is basically the same as the structure shown in FIG. The working dimensions are also different. That is, the relationship between the working dimension M1 of the roof tile module 1 in FIG. 10 and the working dimension M2 of the roof tile module 1 in FIG. 11 is M1 <M2.

  And the difference in the amount of engagement of the ridge side engaging part 321 and the eaves side engaging part 311 arises by the difference in the said working dimension. That is, the engagement amount between the ridge-side engagement portion 321 and the eaves-side engagement portion 311 (the ridge-side module frame 32 is larger in a five-dimensional gradient roof having a larger work size than in a four-dimensional gradient roof having a smaller work size. The overlapping length of the third surface 32c in the eaves side module frame 31 and the sixth surface 31f in the eaves-side module frame 31 is small. At this time, the engagement amount needs to be designed to have an appropriate length so that it can sufficiently withstand the wind load (load weight) even in a five-dimensional gradient with a small engagement amount.

  On the other hand, in order to cope with a four-dimensional gradient in which the engagement amount between the ridge-side engagement portion 321 and the eaves-side engagement portion 311 is large without changing the shape of the frame, a large margin of the engagement portion is taken. In addition, it is necessary to lengthen the lengths of the third surface 32c and the sixth surface 31f themselves (to increase the overlap of the engaging portions).

  Here, in the conventional tile-shaped module, if the margin of the engaging portion is to be increased as described above, in the operation of engaging the engaging portion, that is, in the operation of pulling up the module from below, The work becomes excessive because the amount of pulling is increased. Further, if an attempt is made to increase the margin of the engaging portion, the frame area covering the light receiving surface of the roof tile module increases, and the power generation area decreases. For this reason, in the conventional tile-shaped module, it is difficult to take a large margin of the engaging portion, and as a result, there is a problem that it is not possible to cope with different working dimensions without changing the shape of the frame. It was.

  On the other hand, in the tile-shaped module 1 according to the second embodiment, the engagement between the ridge-side engaging portion 321 and the eaves-side engaging portion 311 is performed with respect to the eave-side tile-shaped module 1A (see FIG. 5). The roof tile module 1B (see FIG. 5) can be moved from the top to the bottom. For this reason, even if the length of the 3rd surface 32c and the 6th surface 31f is enlarged in order to take the margin of the ridge side engaging part 321 and the eaves side engaging part 311 large, work will become excessive. There is no. As a result, in the tile-shaped module 1 according to the second embodiment, the lengths of the third surface 32c and the sixth surface 31f are set to appropriate lengths in consideration of the margin without changing the shape of the frame. It is possible to cope with different working dimensions.

[Embodiment 3]
FIG. 12 is a diagram showing a schematic configuration of the tile-shaped module 11 according to the third embodiment, and illustrates a roof mounting structure when two tile-shaped modules 11 are arranged along the water flow direction A of the roof. To do. The roof tile module 11 according to the third embodiment is substantially the same on both the eaves side and the ridge side, instead of the eaves side module frame 31 and the ridge side module frame 32 of the roof tile module 1 in the first and second embodiments. It is characterized by using a shaped module frame. Here, the structure using the module frame 34 of the same shape on both the eaves side and the ridge side is illustrated.

  The module frame 34 can basically have the same configuration as the eaves-side module frame 31 in the first and second embodiments. That is, the module frame 34 in FIG. 12 is composed of first to sixth surfaces 34a to 34f, and the first to sixth surfaces 34a to 34f of the module frame 34 are the eaves side module frames shown in FIG. This corresponds to the first to sixth surfaces 31a to 31f. Of course, the eaves-side module frame 31 shown in FIGS. 3A and 3B can be used as the module frame 34.

  Further, in order to attach the tile-shaped module 11 according to the third embodiment to the roof, the connecting member 40 is used. The connecting member 40 is made of, for example, an aluminum material, and the cross-sectional shape perpendicular to the longitudinal direction is the same at any location. Moreover, the cross section of the connection member 40 is comprised from the 1st thru | or 5th surface 40a-40e, as shown in FIG.

  The first surface 40a and the second surface 40b are orthogonal to each other, and are formed so that the second surface 40b is erected upward from the middle of the first surface 40a. The third surface 40c is formed by bending backward from the upper end of the second surface 40b. The fourth surface 40d extends obliquely upward from the rear end of the first surface 40a. The fifth surface 40e is formed to protrude downward near the rear end of the fourth surface 40d. Further, in the connection member 40, the upper portion of the second surface 40b and the third surface 40c form a substantially “reverse L” -shaped engagement portion 401 formed by these two surfaces.

  On the roof base plate 100 to which the tile-shaped module 11 is attached, tile rails 101 are arranged at a predetermined interval, and the tile-shaped module 11 is bridged and fixed between these tile rails 101. The tile-shaped modules 11 are rolled in the order from the roof eave side to the ridge side, and the two tile-shaped modules 11 arranged along the water flow direction A of the roof are described here. For convenience, the module disposed on the eave side is referred to as a tile-shaped module 11A, and the module disposed on the eave side is referred to as a tile-shaped module 11B. In this case, the eaves-side tile-shaped module 11A is sown first, and the ridge-side tile-shaped module 11B is sown over it.

  First, the connecting member 40 is placed on the roof bar 101 and fixed. Specifically, the fourth surface 40d of the connection member 40 is fastened and fixed on the roof bar 101 with a wood screw 102 or the like. At this time, the fifth surface 40e may be hooked on the side surface of the roof tile 101 to position the connecting member 40.

  The eaves-side tile-shaped module 11 </ b> A places the third surface 34 c of the module frame 34 on the first surface 40 a of the connection member 40 and the second surface 34 b of the module frame 34 on the second surface of the connection member 40. It arrange | positions in contact with the surface 40b. The roof module 11 </ b> A is attached and fixed to the connection member 40 by fastening the second surface 34 b of the module frame 34 and the second surface 40 b of the connection member 40 with screws 104.

  Next, while placing the third surface 34c of the module frame 34 in the roof tile-type module 11B on the solar panel 2 (light-receiving surface side) of the roof tile-type module 11A, the roof tile module 11B is placed on the building side.

Specifically, the sixth surface 34 f of the module frame 34 is inserted under the third surface 40 c of the connection member 40. Due to the engagement between the engaging portion 401 and the engaging portion 341, the roof tile module 1 can withstand a corresponding wind load (load weight).

  Thereafter, the roof tile module 11 can be sequentially attached along the water flow direction A by repeating the above operation.

  In the roof tile module 11 according to the third embodiment, the module frame 34 having substantially the same shape on both the eaves side and the ridge side is used with the direction of the water flow direction reversed, so the eaves side module frame and the ridge side module frame And the cost of the roof tile module 11 can be reduced.

  Moreover, in this Embodiment 3, the eaves side and ridge side of a module can be arbitrarily determined at the time of construction of the tile-shaped module 11 by sharing an eaves side module frame and a ridge side module frame.

  The tile-shaped module 11 can be configured to use two terminal boxes on the positive electrode side and the negative electrode side in order to extract the output. In such a structure using two terminal boxes, the cable length for electrical connection can be shortened compared to the case where modules are connected with one terminal box. It becomes possible to reduce the output loss and reduce the cost.

This is because when the output of the roof tile module 11 is taken out, the module row in the first stage and the module row in the second stage are connected in series so as to be folded back at the end of the roof.

  At this time, if the structure of the module frame is different between the eaves side and the ridge side, separate roof tile modules 11 are arranged so that the positions of the terminal boxes are reversed between the first stage and the second stage. It is necessary to prepare. On the other hand, in the structure according to the third embodiment, the structure of the module frame on the eaves side and the ridge side is the same, so if a connection member is used, it is only necessary to reverse the arrangement direction at the time of construction. It becomes possible to use the tile-shaped module having the same structure in the second stage and the second stage. That is, the tile-shaped module 11 having the same structure can be used at all stages, and the cost can be reduced by sharing the modules.
