In addition, the infiltration rainwater is smoothly drained from the drainage groove 24 to prevent the lower surface of the solar cell 23 from being always wet, and the deterioration of the solar cell 23 and the roof material body 21 due to long-term use can be prevented.
[0032]
{Circle around (6)} The drainage grooves 24 provided in the roof material 11 with solar cells wound in the upper stage are connected to the roof tiles 1 adjacent to each other, the roof materials 11 with solar cells, or the roof material 11 with solar cells. It arrange | positioned directly on the groove | channel 2, 3 or 4 produced between the roof tiles 1, or the concave groove 12 of the roofing material 11 with a solar cell. Accordingly, the drainage grooves 24 and the grooves 2, 3, 4 or the concave grooves 12 are provided on the same line along the flow direction, so that the drainage from the drainage grooves 24 can be improved and the design feeling can be improved.
[0033]
(7) The above-mentioned (1) to (6) can be realized in the roof using the solar cell roof material 11 by providing the solar cell roof material 11 with the concave groove 12 and further providing the drainage groove 24. .
[0034]
Second Embodiment (FIGS. 5 and 6)
The second embodiment is different from the first embodiment in that a roof material 30 with solar cells is used instead of the roof material 11 with solar cells.
[0035]
The roof material 30 with solar cells is obtained by laminating a thin-film solar cell 32 and a surface protection film 33 on the surface of a roof material body 31 made of metal or the like, and fixing them with a filler such as EVA resin. And even if it is in the roofing material 30 with a solar cell, like the roofing material 11 with a solar cell, the booth is an integer multiple of twice or more of the booth of the roof tile 1, and on the surface of the roofing material 30 with the solar cell, A concave groove 34 along the flow direction is provided at a position where the booths of the roofing material 30 are allocated at intervals equivalent to the booths of the roof tile 1.
[0036]
Even in the second embodiment, the same actions as the actions {circle around (1)} to {circle around (4)}, {circle around (7)} described above in the first embodiment are achieved.
[0037]
Although the embodiment of the present invention has been described in detail with reference to the drawings, the specific configuration of the present invention is not limited to this embodiment, and there are design changes and the like without departing from the gist of the present invention. Is included in the present invention.
[0038]
【The invention's effect】
As described above, according to the present invention, since the roof material with solar cells is provided on a part of the roof, it forms a beautiful line like a tiled roof that is uniformly continuous over the entire roof, and is excellent in design. The appearance of the roof can be obtained.
