Therefore, in order to obtain electric energy using a solar cell, a stand for the solar cell is required, and it is necessary to secure a space for installing the stand, which results in cost reduction. There was a problem in terms of points and space. On the other hand, conventionally, a folded plate roof material that can reduce the number of beams and simplify the configuration has been widely used for roofs of factories and the like. This type of folded plate roofing material has a bottom plate portion, an inclined plate portion that stands up from the side edge of the bottom plate portion, and a top plate portion that is connected to the upper end of the inclined plate portion that are formed continuously. It is placed on top of an object. Therefore, such a folded-plate roofing material is often arranged originally in a place where it receives sufficient solar energy.

However, although the conventional folded-plate roofing material receives the solar energy sufficiently, it does not fully utilize the received solar energy, and it merely functions as a rain shield and an awning. . The present invention was devised by paying attention to these solar cells and folded plate roofing materials, and an object of the present invention is a folded plate roof that can be used as a structure for mounting solar cells and in which solar cells can be easily installed. Is to provide wood.

The solar cell panel 17 is, in the embodiment,
An amorphous solar cell panel is used. As shown in FIG. 2, the solar cell panel 17 includes a stainless steel substrate 1

Below the protective layer 25 of the solar cell panel 17, that is, on the back surface 1703 of the solar cell panel 17,
A base layer 29 made of synthetic resin is provided. The thickness of the solar cell panel 17 excluding the base layer 29 is 3 mm.
Below, it has a certain degree of flexibility, and the underlayer 2
Since 9 is also flexible, it has excellent adhesion to the frame 15. The solar cell panel 17 and the base layer 29 both have a rectangular shape in plan view, and the base layer 29 is formed with a contour larger than that of the solar cell panel 17.

Lead wires 31 are connected to the transparent electrode 23 (+ electrode) and the stainless steel substrate 19 (-electrode), respectively, and these lead wires 31 are elements for preventing current backflow, an overcharge prevention circuit, and a storage battery. Connected to a storage circuit consisting of
The electric power generated by the solar cell panel 17 is stored in the storage battery. It should be noted that the method of using the electric power generated by the amorphous solar cell panel 17 is arbitrary, and the generated electric power is not stored in a storage battery, but is converted from direct current to 100 V alternating current by an inverter circuit, and commercialized from the inverter circuit. It may be supplied to a power source, or may be directly supplied to a DC motor or the like and used to drive it.

The solar cell panel 17 has the bottom plate portion 15

Therefore, it becomes possible to install the solar cell panel 17 simultaneously with the construction of the folded plate roof 1 easily and at low cost.

Further, since the folded plate roof 1 is disposed over the entire upper portion of the structure, the area for receiving sunlight is extremely large, and a large amount of power generation can be expected. Further, in this embodiment, since the inclined plate portion 1503 is formed of the reflection surface having the mirror finish, the sunlight radiated to the inclined plate portion 1503 is reflected by the inclined plate portion 1503 and is reflected on the solar cell panel 17. Since the solar energy is collected, the efficiency of collecting solar energy is further enhanced, and a larger amount of power generation can be expected.

In the embodiment, the case where the solar cell panel 17 is attached to the bottom plate portion 1501 of the frame 15 and the inclined plate portion 1503 of the frame 15 is formed of the reflecting surface has been described. That is, the bottom plate portion 15
01, the inclined plate portion 1503, and the top plate portion 1505, respectively, the solar cell panel 17 is attached, the inclined plate portion 1503
The location where the solar cell panel 17 is attached is arbitrary, for example, the solar cell panel 17 is attached to the bottom panel 1501 with a reflective surface. Furthermore, in the embodiment, the folded-plate roofing material 3 is composed of the frame 15 and the solar cell panel 17, but the frame 15 is omitted and the solar cell panel 17 is omitted.
The bottom plate portion, the inclined plate portion standing up from the side edge of the bottom plate portion, and the top plate portion connected to the upper end of the inclined plate portion are connected to the solar cell panel 17 continuously as in the frame 15.
