PURPOSE:To secure rigidity and flatness of reinforcing members and promote heat exchanging efficiency by giving resistance to the open air and thereby, promote also cooling effects by providing solar batteries, the reinforcing members which are fixed at the back of base plates of solar batteries and have honeycomb-structure, and vent holes formed on the reinforcing members. CONSTITUTION:At the intermediate parts of solar battery base plates 36, reinforcing members 38 are adhered and are made into one body with the base plates. A part of heat generated in semiconductor layers 45 is radiated from the back of the solar battery base plates 36 and the remaining heat is transmitted to the reinforcing members 38 and radiated from the reinforcing members 38. Thereby, air in air flowing parts 31 is heated to be changed into warm air and temp. difference occurs between the open air and warm air. By this temp. difference warm air rises up and are exhausted into the atmosphere from the top openings. And the open air flows into the air flowing parts 31 from open air introducing inlet 49 and the open air flowing through vent holes 48 is forced to rise up while being subjected to resistance by pieces 38D, 38E facing each other and vent holes 48.
