PURPOSE:To utilize solar heat effectively, by collecting solar heat energy in a heat accumulating box, and utilizing solar batteries and thermoelectric generating elements for converting solar heat into electric energy and elements for direct utilization of heat in combination. CONSTITUTION:The sunlight is collected through convex lenses 1-1, 1-n and passed through planoconvex lenses 3-1, 3-n, so that the sunlight is directed substantially in parallel light beams to solar batteries 6-1, 6-n fixed in a heat accumulating box 4. Resultantly, these solar batteries 6-1, 6-n produce electromotive forces and the voltage is taken out through lead wires 14, 15, respectively. In the meanwhile, water passed through a heat absorbing pipe 8 via a valve 11 is heated and stored in a hot- water reserving tank 10. Here, since the water passing through the heat absorbing pipe 8 serves to cool the inside of heat accumulating box 4, the temperature in box 4 is prevented from rising to an extraordinary value. |
