  Conventionally, for example, a solar cell module 30 integrated with tiles for converting solar energy into electricity is arranged on the roof of a house in order to reduce the electrical load in the home as shown in FIG. Photovoltaic roof J is known.

  In the case of such a tile-type solar power roof, the solar cell module 30 is recessed as shown in FIG. 9 so that the solar cell can be embedded in the upper part of the tile material 31 having substantially the same shape as the tile material. In addition, a solar battery 32 in which a transparent body such as glass or resin and a solar battery cell are bonded together is integrated with a resin or an adhesive. Since the solar cell module 30 is not different in shape from the tile material 10 having no other solar cells, the tile material is attached to the pier 9 arranged on the base plate 33 in the same manner as the ordinary tile material construction. 10 tiles can be stacked one after another from the eaves of the roof.

Note that the output wiring 34 output from the solar cell module 30 generally passes the gap between the roof tile 33 and the base plate 33 generated by the overlapping of the roof tiles.

  Further, as shown in FIG. 10, the tiles adjacent to each other in the direction parallel to the roof ridge are engaged with each other by the upper projecting portion 35 and the lower projecting portion 36, and are not easily displaced. .

  However, the tile-shaped solar cell array needs to be wired while the solar cell modules are stacked on the roof surface. Therefore, when the wiring work is completed, the solar cell module is also fixed to the roof surface. Therefore, when there is a mistake in the connection and repair is necessary, or for maintenance / inspection of solar cell modules, many solar cell modules are removed once, and after completion of repairs, maintenance / inspection operations, the solar cell modules are stacked again. There was a problem that had to be.

  Accordingly, an object of the present invention is to provide a solar cell module and a solar cell array for a tiled roof that can solve the above-described problems and can easily perform repair, maintenance, and inspection work of the solar cell module on the roof. And

Further, the other parts are made of a metal material such as aluminum that is lightweight and excellent in strength, but may be a resin material having excellent weather resistance.

  FIG. 2 shows a side view of the solar cell module M with the side frame 14 removed. As shown in the figure, the solar cell module M is configured so that the solar cell modules can be tiled, so that a contact portion 26 placed on the other ridge side end of the other solar cell module or tile material, and the like The solar cell module or the eaves side end of the roof tile is provided with a contacted portion 26a. In this embodiment, the contact part 26 is integrally formed with the eaves side frame 13 so as to protrude downward, and is present in the solar cell module body MU. The abutted portion 26a is formed in the ridge side frame 12, and is in the solar cell module body MU. The casing MD is provided with a fixed rail 16, and an eaves-side fixing bracket 17 and a ridge-side fixing bracket 18 are attached to the fixed rail 16 as locking members.

  The ridge-side frame 12 has a main body portion 26b that forms a polygonal cylindrical body and opens to a side surface.

Wiring can be passed through the hole 26d inside the main body 26b. The main body portion 26b can be elastically deformed. Further, a module gripping piece 26c is extended from the main body portion 26b.

  As is clear from the exploded side view of FIG. 3, the solar cell module body MU is provided with a fixing portion 27 for the casing MD, and a corresponding fixing portion 28 is provided at the eave side end portion of the casing MD. 19 is used to connect the two fixed portions.

  As shown in FIG. 4, the solar cell module M can be installed on the roof K of the building in a mixed manner with ceramic or metal tiles 10. The solar cell module M can also be installed on the entire roof K. In addition, although the tile material 10 in the figure uses a flat roof tile having a flat appearance, it may be a wave roof tile. Moreover, the tiles 10 on the ridge side and the eaves side may be alternately arranged, or the tile members 10 may be arranged in a straight line from the ridge to the eaves. Further, the length of the solar cell module M is set to be approximately an integral multiple of the outer dimension of the roof tile 10.

  Next, a method for assembling the solar cell module M into a solar cell array will be described.

As shown in FIG. 5A, the tile material 10 is installed so as not to slide down to the eaves side by hooking a depression on the pier 9 arranged on the field board 33. The eaves side receiving metal fitting 20 is fixed with screws or nails on the base plate 33 on the ridge side of the tile material 10. Then, the engaging portion 21 of the eaves side receiving metal fitting 20 and the engaging portion 22 of the eave side fixing metal fitting 17 of the solar cell module M are fitted, and the ridge side fixing metal fitting 18 of the solar cell module M is attached to a nail 24, a screw nail or the like. Then, it is fixed on the base plate 33 by hitting it.

  FIG. 5B shows a connection mode between the solar cell modules. As shown in the figure, the extension piece 23 with the folding provided on the ridge side frame 12 of the solar cell module M1 and the engaging portion 22 of the eaves side fixing bracket 17 of the solar cell module M2 are fitted, and the solar cell module The ridge side fixing bracket 18 of M2 is fixed on the base plate 33 with a nail 24 or the like.

A rain repellency structure is formed by the upper protruding portion 25 provided in the contacted portion 26a of the ridge side frame 12 to prevent intrusion of rain and wind.

  Next, a method for removing the solar cell module body MU from one solar cell module M2 (second solar cell module) will be described. As shown in FIG.6 (b), the coupling screw 19 which fastens the eaves side frame 13 and the eaves side fixing metal fixture 17 in the solar cell modules M2 and M3 is removed. At this time, as shown in FIG.6 (c), the solar cell module main body MU of the solar cell module M3 (1st solar cell module) can be lifted slightly. This is because the main body portion 26b of the ridge side frame 12 can be elastically deformed. And the solar cell module main body MU can be removed by slightly lifting and pulling out the eaves side frame 13 of the solar cell module M2.

  The solar cell module body MU of the solar cell module M2 cannot be removed unless the solar cell module body MU of the solar cell module M3 is lifted and slightly lifted. When it is not lifted, the upward projecting portion 25 provided on the ridge-side frame 12 of the solar cell module body MU is caught by the contact portion 26 of the solar cell module M3 to prevent it from coming off. Therefore, the solar cell module body MU is prevented from sliding off without permission.

  Next, the horizontal connection method of the solar cell module M will be described.

  A load receiving plate 15 is attached to the back surface of the side frame 14 of the solar cell module M, and corresponds to the coupling between the solar cell modules and in the lateral direction (horizontal direction with respect to the building) of the solar cell module and the roof tile.

  Specifically, as shown in FIG. 7A, the load receiving plate 15 is inserted into a rail portion 37 provided at the lower portion of the side frame 14, and the load receiving plate 15 is integrated with the solar cell module M. It has become. When the solar cell modules M (the first solar cell module and the third solar cell module) are arranged side by side, the load receiving plate 15 enters the lower part of the adjacent solar cell module M4. While supporting the side frame 14 of M4, it plays the role which flows rainwater etc. which penetrate | invade from the clearance gap produced between the side frame 14 and the side frame 14 to the eaves side.

  Similarly, when the roof tile 10 is arranged next to the side frame 14 as shown in FIG. 7C, rainwater entering from the gap between the side frame 14 and the roof tile 10 is allowed to flow to the eaves side. To play a role.

  Moreover, as shown in FIG.7 (b), when the tile material 10 is distribute | arranged to the side frame 14 side of the solar cell module M, the side frame 14 is located above the lower protrusion part 36 of a tile material. Then, for rainwater and the like entering from the gap between the side frame 14 and the tile material 10, the lower protrusion 36 of the tile material 10 functions as a kite.

  The load receiving plate 15 can be attached to either the left or right side frame 14 and has a high degree of freedom in installation that can be applied regardless of whether the roof material is arranged on the left or right side of the solar cell module M. Furthermore, any tile material can be accommodated by making the shape of the load receiving plate suitable for various tile materials. The load receiving plate 15 may be fixed to the rail portion 35 with screws or the like.
