Further, the ends of the solar cell panel 1 in the direction perpendicular to the inclination direction are provided with waterproof rails 3 arranged side by side on the roof 2.
Therefore, even if rainwater or the like intrudes into the roof 2 side from between the solar cell panels 1 adjacent in the direction orthogonal to the inclination direction, the rainwater or the like flows along the gutter-like portion 34 of the waterproof rail 30. Since the roof 2 can flow down toward the lower end in the inclination direction, that is, toward the eaves, good waterproofness can be secured.

The mounting member 40 is fixed to the solar cell panel 1 via a double-sided tape (not shown).
The mounting member 40 can be easily fixed to the solar cell panel 1.

The solar cell panel 1 has a mounting member 4
0 is attached, so solar panel 1
Can be installed in a stable state without tilting with respect to the roof 2.

In the embodiment described above, the two attachment members 40 are attached to the solar cell panel 1, but may be one, or
Three or more may be attached. When three or more mounting members are mounted, all the fixing portions of the mounting members do not need to be fixed to the roof, and the solar cell panel may be connected to the roof.

Although the mounting member 40 of the above-described embodiment is fixed to the solar cell panel with a double-sided tape, it may be mounted using other fixing means such as an adhesive or a fastener such as a screw. Further, the upper end engaging portion 46 and the lower end engaging portion 47 of the attachment member 40 are not limited to those having a structure in which the concave and convex are fitted, and any structures can be applied as long as they can engage with each other.

In the mounting member 40 of the above-described embodiment, the fixing portions 44 and 45 are also used as the convex portions 461 and 471. However, fixing portions may be provided separately from these convex portions. Further, in the above-described embodiment, of the fixing members 44 and 45 of the mounting member 40, only the fixing portion 44 on the upper end side in the tilt direction of the roof 2 is fixed to the roof 2 except for the mounting member of the solar cell panel at the lower end in the tilt direction. Although fixed, the fixed portion on the lower end side in the inclined direction may be fixed to the roof. Further, in the above-described embodiment, the spacer 52 is disposed between the mounting members 40, but the spacer may be omitted. In the above-described embodiment, the side part orthogonal to the inclination direction of the solar cell panel 1 is supported by the waterproof rail 30, but this waterproof rail may be omitted.

In the above embodiment, the inclined roof is described. However, the type of the roof is not particularly limited, and the present invention can be applied to a case where a solar cell panel is installed on a roof such as a land roof or a ridge.
