PURPOSE:To use a solar battery panel in a long term without any deterioration of its energy conversion efficiency. CONSTITUTION:A solar battery panel 11 comprising plate-form solar battery main bodies 14 and the case of a heat accumulating substance 15 which is mounted on the rear surface sides of the main bodies 14, etc., is provided on a roof 13 of a dwelling house 12. The heat accumulating substance 15 (sodium sulfate, etc.) is filled into a case 17 of the heat accumulating substance 15, and each of the top and bottom surfaces of the case 17 has a nearly equal area to the summed area of the rear surfaces of the solar battery main bodies 14. Since the case 17 of the heat accumulating substance 15 is so mounted as to be contacted closely with the rear surface sides of the main bodies 14, the case 17 of the heat accumulating substance 15 is provided extensively on the nearly summed area of the rear surfaces of the main bodies 14. Therefore, when the solar battery panel is operated, its temperature rise is suppressed by the melting of the heat accumulating substance 15. |
