PURPOSE:To obtain electrical energy out of solar energy simply at low cost by a method wherein amorphous solar battery panels are attached to the sunbeam receiving surface of a plurality of blades that are provided so that they can be opened and shut. CONSTITUTION:A plurality of blades 9 are provided to the upper part of a structure like a terrace so that the blades can be opened and shut. When the blades 9 are in the state of closing, intrusion of rainwater into the structure is prevented and when the blades are in the state of opening, sunbeam is taken into the structure in accordance with the degree of opening. In an opening/ shutting type roof 7 as mentioned above, amorphous solar battery panels 11... are attached to the sunbeam-receiving surfaces of the blades 9. Thereby, a stand for exclusive use for installation of the solar battery can be eliminated, and a space for installation of such stand becomes unnecessary. |
