PURPOSE:To reduce the weight and heat collecting efficiency of the titled device and to increase the power generating efficiencies of solar batteries by a method wherein a corrugated heat collecting plate is arranged within a heat insulating box and the solar batteries are attached to the inclined surfaces, respectively, of the heat collecting plate formed on the sides between the crests and the troughs of the corrugations. CONSTITUTION:A transparent plate 7 is laid over a flat air passage 3 so as to cover the upper opening of the passage 3 and the heat collecting plate comprising a thin corrugated plate 8 having ridge lines extending in the direction of the flow of air is provided within the air passage 3 and the solar batteries 9 are attached to the inclined surfaces, respectively, of the heat collecting plate formed between the crests and the troughs of the corrugations on the side adjacent to the transparent plate 7. As a result, the heated heat collecting plate 8 is cooled by the flow of air from on both upper and lower surfaces thereof and a high heat collecting efficiency is obtained. Further, as the solar batteries are attached to the inclined upper surfaces of the corrugated heat collecting plate, it is possible to increase the surface area of power generation. In addition, it is also possible to control the lowering of the power generating efficiecy of each of the solar batteries 9 to a minimum. Thus, with the above structure, the heat collecting efficiency of the solar heat collecting plate and the power generating efficencies of the solar batteries are increased in proportion to an increase in the flow rate of air. |
