[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a waterproof structure for a roof panel with solar cells, which is installed on a roof panel of a building with a waterproof function provided at a joint between a plurality of solar cell panels.

[0002]

2. Description of the Related Art In recent years, it has been practiced to utilize solar energy effectively by arranging a plurality of solar cell panels side by side on a roof of a house to generate power, and utilizing the power from the solar cell panels. I have. The solar cell panel installed on the roof is a unit formed by joining a plurality of solar cell modules (for example, see Japanese Patent Application Laid-Open No. 3-19956).
No. 6).

[0003]

However, when such a solar cell panel is installed on a roof, the solar cell panel is not installed on a roof tile but on a roof (roof frame) as a roof tile. It is considered to be installed directly. In this case, it is desirable to improve the sealing property of the part where the solar cell panel is attached to the roof and the sealing property of the part where the solar cell panels are joined together.

Accordingly, the present invention provides a waterproof structure for a roof panel with a solar cell which can sufficiently secure the sealing performance of a portion for attaching a solar cell to a roof and the sealing performance of a portion for joining solar cell panels together. The purpose is to provide.

[0005]

In order to achieve this object, a first aspect of the present invention is a panel in which a plurality of solar panels are juxtaposed on a roof panel and extend along an edge of the solar panels. A holding member is provided, the solar cell panel is held at an edge of the panel holding member, and the panel holding member is fixed to the roof panel by a fastening member held by the panel holding member. A waterproof structure for a roof panel with a battery, wherein the panel holding member includes a first member through which the fastening member penetrates, and a second member mounted on the first member, and an edge of the first member. A step for sealing is provided in the first member and stands between the fastening member, a waterproof sheet is stretched between the roof panel and the roof member, and is extended from an end of the roof panel. Waterproof waterproof When, characterized in that the tarpaulin, which extend from the roof panel ends facing is bonded.
