Side water stop means 6 was used. Further, in order to prevent rainwater from entering under the roof tile 12 through the girder side water stopping means 6, a part of the roof tile 12 on the module side is caulked with a caulking material 7.

According to such a configuration, it is possible to more reliably prevent rainwater from entering from both sides of the photovoltaic power generator.

FIG. 7 is an enlarged sectional view of a main part on the eaves side for explaining a third embodiment of the present invention. As shown in the figure, in this embodiment, on the eaves side of the photovoltaic power generation device, from the lower part of the support member 1 to the upper surface of the eaves-side tile 12, a water-impermeable member such as a metal plate is used. Water guide means 7 is provided.

In this embodiment, the rainwater discharged from the drainage path 1b of the support member 1 is guided by the water guide means 7 onto the eaves tile 12 and then drained to the outside by a normal rain gutter. . In addition, since the support member 1 is placed on the water guiding means 7 instead of on the fragile roof tile 12, the reliability is high with respect to the weight of the photovoltaic power generation device, and high with respect to rain leakage. A power generator can be provided.

Next, another embodiment relating to the attachment of the solar cell module 2 to the support member 1 in the present invention is shown in FIG.
This will be described with reference to the main part enlarged sectional view shown in FIG.

Was. Therefore, in the present embodiment, the mounting portion 2c is formed so as to protrude from the lower side of the frame portion 2b and bend further upward.

Further, the mounting portion 1a of the support member 1 is provided with upright screws 20 at a predetermined pitch so that the screw portions are directed upward. The erected screw 20 is provided by penetrating a bolt (20) through a hole formed in the mounting portion 1a and fixing it with a nut 21, but it is more preferable that the screw be erected by welding.

Then, the opposing side edges of the solar cell modules 2, 2 provided on both sides of the vertical screw 20 are fixed by the pressing plate 25.

The holding plate 25 has a U-shaped cross section and has a hole through which the standing screw 20 is inserted. When the upright screw 20 is inserted into this hole and the nut 26 is screwed into the upright screw 20, both ends of the holding plate 25 engage with the hook-like portions 2 c of the solar cell module 2, thereby holding the solar cell module 2. It is fixed on the support 1.

According to such an attachment method, since there is only a portion where there is a possibility of water leakage and a portion stopped by the nut 26, the waterproofness is further improved as compared with the conventional case.

As shown in FIG. 9, the shape of the pressing plate 25 may be such that the upper surfaces of the opposing side edges of the adjacent solar cell modules 2 can be pressed. According to such a shape, the holding plate 25 can also be used as a decorative plate.
