PROBLEM TO BE SOLVED: To prevent power generation efficiency from being lowered by supporting a solar battery panel set on a building and providing a support block forming a space between the building and the solar battery panel. SOLUTION: A solar battery panel 5 comprising panel units 4, 4,... is supported in a state separated from the upper face 2a of a rooftop 2 by support blocks 10, 10,... disposed on a buffer 11 provided on the upper face 2a of the rooftop 2 of a building. The solar battery panel 5 is fixed by the support block 10 for the rooftop 2, and since a space S is formed between the solar battery panel 5 and the rooftop 2 by means of the support block 10, draft is performed for the space S. Thereby temperature increase in daytime or the like of the solar battery panel 5 is suppressed, and power generation efficiency of a solar battery 5 is increased. Thus, the lowering of the power generation efficiency by temperature increase of the panel of the solar battery can be prevented. |
