Therefore, in order to obtain electric energy using a solar cell, a stand for the solar cell is required, and it is necessary to secure a space for installing the stand, which results in cost reduction. There was a problem in terms of points and space. On the other hand, at a construction site, a protective panel is attached to a support member assembled to the outside of the building so as to surround the periphery of the building, or a support panel diagonally upward is attached to the support member assembled to the outside of the building (morning glory). Is attached. However, although this type of protective panel has a large area as a whole, it simply means that
It only functions in terms of preventing falling of materials and equipment, blindfolding, and safety. The present invention has been devised by paying attention to such a solar cell and a protective panel, and an object of the present invention is to easily obtain electric energy from solar energy using the solar cell and the protective panel. It is to provide a protection panel integrated with a solar cell panel.

[0004]

To achieve the above object, the present invention relates to a solar cell panel attached to a support member assembled to the outside of a building so as to surround the periphery of the building when the building is constructed. The body protection panel is characterized by including a rectangular frame-shaped frame having a mounting portion coupled to the support member, and a rectangular thin-plate solar cell panel attached to the frame.

Further, the present invention is a solar cell panel-integrated protective panel which is obliquely attached to a support member assembled to the outside of the building when the building is constructed, and is connected to the support member and is substantially vertical. And a rectangular frame-shaped frame attached obliquely upward to the lower end of the reflection plate, and a rectangular thin-plate solar cell panel attached to the frame. And

The present invention is also characterized in that the solar cell panel is an amorphous solar cell panel. Also,
The present invention is characterized in that a base layer made of synthetic resin is provided on the back surface of the amorphous solar cell panel.

[0007]

When a solar cell panel-integrated protective panel is assembled in the same manner as the conventional protective panel, a large number of solar cell panels are stretched at the same time as the protective structure is assembled.
