Regarding the structure of the mounting part.

Conventionally, various structures have been known for attaching roof-integrated collectors to the roof, but all of them have the disadvantage that the collector support structure is complex and that sufficient support strength cannot be obtained. A complex watertight structure was required in the adjacent parts of the collectors.

The present invention provides a roof mounting structure for a solar energy collector that eliminates the conventional drawbacks, and will be described in detail below with reference to the drawings.
