Description of the Related Art Conventionally, solar cells have generally been referred to as roof-top solar cells in which a polycrystalline silicon or single crystal silicon solar cell is placed on a roof surface. Recently, polycrystalline silicon integrated with a metal roofing material has also been developed. On the other hand, as shown in JIS A 6008 "Synthetic polymer roofing sheet", the waterproof sheet is a polymer sheet made of vulcanized rubber, vinyl chloride, ethylene or asphalt-based non-vulcanized rubber, which is joined by welding or bonding. The one that forms an integral waterproof layer is a general sheet waterproof.

電力は期待できないが、機能上なんら支障がない。The installation of the solar cell integrated sheet waterproofing material on the roof surface according to the present technology does not require a special place for installing the solar cells, and requires only the same construction as the normal sheet waterproofing to achieve the roof waterproofing and the solar water protection. The installation of the batteries is completed at the same time, and no special scattering / fall prevention measures for solar cells are required. In addition, since the solar cell sheet is formed on the upper surface of the waterproof sheet, the lower waterproof sheet (in this example, a sheet of PVC or EPDM) is not directly irradiated with ultraviolet rays, so that high durability as the waterproof sheet is ensured. Can be. In addition, solar cells are applied to the entire roof surface, and the surface exposed to sunlight generates electricity,
Even if there is a shadow portion other than that, power generation for the area of the shadow cannot be expected, but there is no problem in function.
