When the cover member is made opaque, the power generation of the solar cell device is stopped at the time of such a disaster, and it is possible to prevent the occurrence of an electric shock accident or an electric leakage.
On the other hand, in the state in which the cover member is housed, there is nothing that blocks the transmission of sunlight to the light receiving surface of the solar cell device, so that the solar cell device has a higher power generation efficiency than the case where the tempered glass is arranged in two or three layers. Can be run at. Further, by providing a storage means for storing the extended cover member, the cover member can be used many times.
