１００ Ｗの電力が得られる。(Prior art and its problems) Recently, solar power generation has been attracting attention as an alternative energy to underground energy. With the characteristics of current solar cells,
A maximum of about 100 W of power can be obtained by placing a single layer of solar cells together and exposing them to sunlight.

欠点を有していた。If the electricity used in a typical household, i.e. 2 to 3 kW, is to be provided by solar power generation, the installation area of the solar cells will be 2.
0 to 30 m is required. This area is usually sufficient for the roof area of a house. Therefore, in order to utilize this area, conventional methods have been to adhere solar cells to the surface of roof tiles (Utility Model Application No. 11261/1983), or to deposit amorphous silicon solar cells on the back surface of translucent roof tiles. It is proposed to do so. This allows the roof space to be effectively used as a place to install solar cells. However, in the above-mentioned conventional technology, in order to electrically connect multiple tiles to each other, the tiles must be connected one by one using lead wires in the attic, which requires extremely complicated and difficult work. Shirakudomijo j0 Additionally, there was a decisive drawback in that the power generation efficiency was extremely reduced if the installation azimuth of the tiles with solar cells installed in this way was not facing south.

用的な太陽光発電可能な屋根となる。In addition, the roof capable of solar power generation according to the present invention has a solar power generation capacity of 5'I even when sunlight is scattered by clouds, atmospheric dust, etc.
This results in a high electromotive force in the pond. That is, it is difficult to predict which direction and angle the scattered light from the sun will be incident on the ground, but depending on the tilt of the reflector 40, the clutter of the solar cell 30, etc., the scattered light can effectively irradiate the solar cell 30. (Effects) As described above, the present invention provides solar cells on one slope of the corrugated roof of a house formed in a corrugated shape,
By providing a reflective means on the other slope opposite to the slope on which the solar cells are installed, it is possible to obtain a high electromotive force from the solar cells even on a gable roof facing in any direction or on a flat roof, making it easy to install. The degree of freedom is significantly improved, and the roof becomes a solar-protected roof that can always generate high electromotive force even under cloudy skies or conditions where light scattering is likely to occur. Furthermore, a passageway for mountain water to flow down is provided in the valley where the slope on which the solar cells are provided intersects with the slope on which the reflective surface is formed, thereby improving the moisture resistance of the solar cells and the reflective surface. At the same time, this part will serve as a foothold during roof installation and maintenance work, making it an extremely practical roof capable of generating solar power.
