PURPOSE:To contrive improvement in the heat-radiating property of a module and the shock-proof property on the rear surface of the module by a method wherein the surface of the supporting member provided on the rear side of a solar battery module is formed into an uneven surface suitable to increase the surface area. CONSTITUTION:The supporting member 6a, provided on the rear side of a solar battery module, has a frustum shape having recesses and protrusions, using a moisture-proof sheet, for example. In this case, the uneven surface of the moisture-proof sheet 6a is formed into a frustrum, but the uneven surface may be formed into a wave-like form, a rectangular shape or a cone shape and the like. As a result, the surface area of the rear side of a module is increased and the area of the rear of module which comes in contact with the atmospheric air is increased, the efficiency of the heat in the module radiated into the air is enhanced, and the temperature rise in the module is suppressed. Also, when some substance such as a flying object and the like is collided with the rear side of the module, the shock of collision is first absorbed by the protrusions on the rear surface, and the impact given to the solar battery 1 is made very small. |
