In order to manufacture the solar roofing 20 in this case, a plurality of solar cell elements 2 connected in parallel on a flexible roofing base material 1 are arranged by sandwiching them with a thermo-adhesive sealing resin 3 such as EVA. Then, a release sheet (not shown) is arranged thereon and laminated by a roll-to-roll method. Thereafter, the release sheet is peeled off and wound into a roll to obtain a solar roofing 20 as shown in FIG. At the time of installation, the surface of the sealing resin 3 and the surface protection plate 5 are brought into contact with each other by applying an appropriate pressure in the direction of arrow 7 and are simultaneously bonded by heating to about 100 to 150 ° C. As a heating method, first, heating by sunlight is cited. Usually, the daytime surface temperature of a solar cell is 60 to 70 ° C in summer and 30 to 4 in winter.
It reaches 0 ° C. The surface temperature rises further by covering the surface with a translucent sheet, and is 100 ° C. or more in summer and 7 in winter.
0 ° C or higher. Therefore, a sufficient heating effect can be obtained in summer, and a sufficient heating effect can be obtained even in winter by using heating from above with hot air such as a hot plate, a burner, or an electric heater. Of course, heating by a hot plate or hot air may be used alone. In the case of this embodiment, the sealing resin 3 also serves as an intervening layer after the solar cell shown in FIG. When using tempered glass with a refractive index of 1.5 as the material of the surface protection plate 5 and EVA with a refractive index of 1.5 as the material of the sealing resin 2, the effect of eliminating the air gap on output improvement is about 8%. It is.

すぐれた長寿命の住宅用太陽電池を実現できた。According to the present invention, since the surface protection plate and the solar roofing are bonded to each other, the space therebetween is filled with the intervening layer and there is no air gap, so that the reflection loss is greatly reduced. When a tempered glass having a refractive index of 1.5 was used as the surface protection plate, an output improvement of about 8% was obtained by the present invention. Further, since there is no water intrusion path through the air gap, the surface protection plate also serves as a moisture blocking material, and the water resistance of the solar cell is greatly improved.
Therefore, a long-life residential solar cell with high output and excellent water resistance can be realized while maintaining low cost and ease of construction, which are the inherent merits of solar roofing.
