- the upper metal plate 13 and the lower metal plate 11 can be easily connected by bending the bent portions 16a to 16f of the upper metal plate 13. For this reason, the manufacturing process of the tile-integrated solar cell module 4 can be simplified as compared with the case where the upper metal plate 13 and the lower metal plate 11 are joined using screws or an adhesive.
- the adhesive is dissolved and removed when the tile-integrated solar cell module 4 is recycled. Such a step becomes unnecessary. Therefore, the tile-integrated solar cell module 4 can be easily recycled.
- the bent portions 16c to 16f are arranged in a direction intersecting the eaves direction of the upper metal plate 13 (that is, the overlap portions 18 and It is formed on the left-right direction side where the underlap portion 19 is formed.
- the lower metal plate 11 as the other exterior plate has convex portions 15 a and 15 b for supporting the solar cell power generator 3 (see FIG. 8).
- the roof tile-integrated solar cell module 4 has a cushioning member 20 (see FIG. 8) serving as a cushioning member for the power generator disposed between the solar cell power generator 3 and the lower metal plate 11 constituting the exterior member. Is further provided. In this case, the presence of the cushioning member 20 can further reduce the possibility that the central portion of the solar cell power generator 3 will come into contact with the lower metal plate 11 constituting the exterior member. Therefore, the probability of occurrence of scratches on the surface of the solar cell power generator 3 can be further reduced. It should be noted that a cushioning material as a power generator cushioning member may be arranged between the upper metal plate 13 and the solar cell power generator 3 constituting the exterior member.
- the solar cell power generator 3 may include the solar cell 1 (see Fig. 3). Determined based on dimensions. In this case, the size of the photovoltaic power generator 3 is determined based on the outer dimensions of the photovoltaic cell 1 without cutting when the photovoltaic cell 1 is cut to fit the dimensions of the tile-integrated photovoltaic module 4. Will be. That is, the solar cell power generator 3 can be used as a common component for the tile-integrated solar cell module 4 having different sizes.
- the tile-integrated solar cell module 4 is in a state where the tile-integrated solar cell module 4 is installed on a rooftop, and the roof tile-integrated solar cell module 4 and the tile-integrated solar cell module 4 are evacuated.
- the eaves cover 25 (see FIG. 12) as one member to fill the gap between the roof tiles 22 located adjacent to the side, and the roof-integrated solar cell module 4 and the roof-integrated solar cell module 4 To fill the gap between the roof tiles 22 located on the ridge side
- At least one of a ridge side cover 27 (see FIG. 15) as a ridge side cover member is further provided.
- the eaves front cover 25 and the ridge side cover 27 include a portion having a surface shape along the surface shape of the roof tile 22 (the corrugated portion 29 of the eaves front cover 25 or the upper end of the ridge side cover 27).
- the gap between the roof tile-integrated solar cell module 4 and the adjacent roof tile 22 is filled with the eaves force bar 25 or the ridge side cover 27, so that the roof tile-integrated solar cell module 4
- the appearance of the roof can be prevented from being impaired due to the presence of a gap between the roof tiles 22.
- the eaves cover 25 or the ridge side cover 27 the waterproof performance of the roof on which the tile-integrated solar cell module 4 is installed can be maintained well.
- the roof tile-integrated solar cell module 4 at least one of the eaves top cover 25 and the ridge side cover 27 is provided with a cushioning member having a waterproof function (the cushioning material 35 provided on the eaves top cover 25 (see FIG. 16) or a cushioning material 36 (see Fig. 17) installed on the ridge side cover 27 may be installed.
- the waterproof performance of the tile-integrated solar cell module 4 can be improved, and the workability of the tile-integrated solar cell module 4 can be improved.
- a coloring layer 17 is formed on the surface of an exterior member (for example, the upper metal plate 13 constituting the exterior member).
- the tile-integrated solar cell module 4 is installed by forming a colored layer 17 having a color that matches the color of the other tiles 22 on the roof to which the tile-integrated solar cell module 4 is applied. The possibility that the aesthetic appearance of the roof is damaged by the tile-integrated solar cell module 4 can be reduced.
- the solar cell is located on the eaves side when the roof tile-integrated solar cell module 4 is installed on the roof.
- the shapes of the upper metal plate 13 and the lower metal plate 11 are determined so that an opening through which the power generator 3 can be taken out is formed. That is, in the upper metal plate 13, no convex side wall is formed on the eave side so as to prevent removal of the solar cell power generator 3. Similarly, in the lower metal plate 11, no protrusions or side walls are formed on the eaves side, which prevent the solar electric power generator 3 from being taken out.
- the exterior member closes the opening.
- an eave-side metal plate 12 (see FIG. 1) as an eave-side exterior plate that is detachably mounted to the upper metal plate 13 and the lower metal plate 11 that constitute the exterior member.
- the tile-integrated solar cell module according to the present invention can be applied to tiles of various sizes, and the same tile-integrated solar cell module can be applied to tiles of various sizes. It is suitable for constructing a low-cost solar cell system by using it.
