Description

  The present invention relates to a solar cell module that generates power using solar energy, and a solar cell array in which a plurality of solar cell modules are installed on a roof of a building and the solar cell modules are stacked on top of each other.

  Due to the recent increase in environmental awareness, solar power generation, in which solar cell modules are installed on the roofs of ordinary houses and public buildings, to generate electricity, has attracted attention as clean energy.

  Conventionally, as one of such photovoltaic power generations, for example, a photovoltaic roof J, in which a tile-integrated solar cell module 30 is arranged on a roof of a general house as shown in FIG. It has been.

  In the case of such a tile-shaped solar power roof J, the solar cell module 30 has a recess formed in advance on the top of a tile-shaped main body 31 that has substantially the same shape as a normal tile member 10 as shown in FIG. Then, a solar cell 32 covered with a light-transmitting material such as glass or resin is embedded in the concave portion and integrated with an adhesive. Since the tile-like solar cell module 30 is not different in shape from the tile material 10 having no solar cell, the installation on the roof of the tile-like solar cell module 30 is the same as the ordinary roof material 10 construction. This is possible by a method in which the tiles 10 are sequentially tiled from the eaves of the roof onto the pier 9 arranged above. Here, the output wiring 34 output from the solar cell module 30 is generally formed by making a hole in the tile-shaped main body 31 and passing it down, and wiring and connecting in the gap between the tile-shaped main body 31 and the base plate 33. It is.

  Further, as shown in FIG. 11, the tile members 27 adjacent to each other in the direction parallel to the roof ridge are engaged with each other by a first projecting portion 35 projecting downward and a second projecting portion 36 projecting upward. Thus, the roof tiles 27 are not easily displaced from each other. Therefore, in the case of using such a tile-like solar cell module 30, a solar cell module 30 that fits into the first projecting portion 35 and the second projecting portion 36 of the tile material 26 must be prepared and prepared. There was annoyance that it was not.

As a countermeasure, a module body is held in the recess, and a side frame is provided in the recess, and a load receiving plate that receives a load of another solar cell module or a tile material is fixed to the side frame along the entire length. The solar cell module which provided the plate fixing | fixed part of this is devised (for example, refer patent document 1). According to such a solar cell module, it is possible to cope with the difference in the shape of the tile material only by changing the shape of the load receiving plate.

  A module main body is held in the concave portion as described above, and a side frame is provided in the concave portion, and a load receiving plate for receiving a load of another solar cell module or a tile material is fixed to the side frame along the entire length thereof. Even in solar cell modules with plate fixing parts, it is necessary to fix the solar cell modules on the roof surface while stacking them partially and wiring them at the same time. At the completion of the step, the solar cell modules are connected to each other together with being fixed to the roof surface of the solar cell modules. Accordingly, there is a problem that if the work for removing the solar cell module from the roof surface becomes necessary later due to an error in connection or the like, the work becomes complicated.

  In addition, maintenance / inspection work for solar cell modules and the like is not easy as long as it is necessary to remove the solar cell modules.

  Furthermore, according to the general roofing material construction procedure, the worker arranges the solar cell module from the eaves side, so the worker needs to get on the solar cell module. At this time, since the surface of the solar cell module is made of glass or the like as described above, it is slippery and dangerous for the operator.

  Further, when the solar cell module is installed by a frame structure instead of the tile-shaped main body of FIG. 10 as in Patent Document 1, a roof material is provided below the solar cell module and its output wiring. Because there is no fire protection sheet for the part where the solar cell module is installed on the roof surface, the fire protection sheet is placed on the base plate before installing the roofing material or solar cell module. It will be a difficult task. Therefore, it was decided to lay a fire-proof sheet on the entire surface of the field board, and a fire-proof sheet was also laid on the part where the roofing material where the solar cell module was not installed was installed, and the fire-proof sheet was required more than the necessary area . Also in the structure as shown in FIG. 10, a hole is made in order to pass the output wiring 34 through the tile-shaped main body 31 and the output wiring 34, which is a combustible material, is passed between the base plate 33 and the tile-shaped main body 31. Not preferable. In addition, if the output wiring 34 is housed in the tile-shaped main body 31 in consideration of fire prevention, it is difficult to connect the output wiring between the solar cell modules.

  The present invention has been made in view of the above problems, and wiring work for connecting solar cell modules to each other can be performed collectively, and solar cell module installation work, maintenance and inspection on the roof can be performed. A solar cell module for a tiled roof, a solar cell array using the solar cell module, and a method for manufacturing the solar cell array, which can easily perform work and the like, can minimize the use amount of the fireproof sheet, and have fireproof performance The purpose is to provide.

  The solar cell module of the present invention is disposed between a solar cell panel, a frame body having a concave portion for accommodating the solar cell panel, the solar cell panel and the bottom surface of the concave portion, and can be detachable from the concave portion. And a member.

  Moreover, the solar cell module of the present invention is the above module, wherein the concave portion has a through hole penetrating the frame body on a bottom surface thereof, a support portion provided around the through hole, and supporting the fireproof sheet from below. It is characterized by having.

  Furthermore, the solar cell module of the present invention is characterized in that, in the above module, the solar cell panel is detachable from the recess.

  Furthermore, the solar cell array of the present invention is characterized in that the above-described plurality of solar cell modules are arranged in the module.

  Moreover, the solar cell array of the present invention is characterized in that in the above array, the adjacent solar cell modules are arranged so as to partially overlap each other.

  Furthermore, the manufacturing method of the solar cell array of the present invention includes a step of preparing a plurality of solar cell panels, a plurality of frames having recesses for accommodating the solar cell panels, and a plurality of fire prevention members, A step of disposing a frame on the roof; a step of disposing a fireproof member in the recesses of the plurality of frames disposed on the roof; and the solar cell on the fireproof member disposed in the recess of the frame. And a step of arranging the panel.

Moreover, the manufacturing method of the solar cell array of the present invention includes a step of preparing a plurality of solar cell panels, a plurality of frames having recesses for accommodating the solar cell panels, and a plurality of fire prevention members, A step of arranging the frame on the roof, a step of attaching a fireproof member to the back surface of the solar cell panel, and a step of arranging the solar cell panel to which the fireproof member is attached in the recess of the frame. And.

  According to the present invention, the frame body can be arranged in the procedure of arranging the roofing material before arranging the solar cell module on the roof. In addition, since the worker uses the ground exposed from the through hole in the recess of the frame as a scaffold, the frame can be attached without riding on the surface of the solar cell module.

  In addition, after mounting the frame body, by alternately fixing the fireproof member to the frame body and mounting the solar cell panel having a power generation function, the wiring can be performed in accordance with the wiring layout without matching the roof material placement procedure. You can concentrate on the work, you can install fire prevention members only on the back side where the solar panel is installed, and there is no fire prevention member on the back side of the roof material around the solar panel, and there is an extra fire prevention sheet unnecessary.

  Furthermore, since the fireproof member is fixed in the recess of the frame, if the output wiring of the solar cell panel is placed on the fireproof member, there is no need to bind to the frame.

  Moreover, a solar cell panel can be replaced | exchanged or wiring can be confirmed, without removing a frame from a roof material.

  Furthermore, by using a solar cell array in which a plurality of solar cell modules are stacked on top of each other, the above-described effect can be ensured over the entire surface where the solar cell modules on the roof are installed.
