PPROBLEM TO BE SOLVED: To enhance energy use efficiency of solar light by efficiently performing power generation and hot water supply as cogeneration. PSOLUTION: By fusing a solar light and heat combined power generation system 10 and a COSB2/SBrefrigerant heat pump system 30 together via a cooling water circulation system 20, power generation and hot water supply are covered as a cogeneration system. That is, electric power generated by a thermoelectric element 14 and a solar battery 15 is accumulated and is used as an energy source for driving the heat pump system 30. Waste heat from the thermoelectric element 14 and solar battery 15 is recovered by cooling water, is recovered again by a carbon dioxide refrigerant in the heat pump system 30, and is used as a heating source for generating hot water in the heat pump system. The cooling water of which heat is released to the heat pump system 30 becomes low temperature and is returned to a water supply tank 22 again. PCOPYRIGHT: (C)2010,JPO&INPIT
