Abstract
Aiming at reduction of the energy consumed in domestic use, research and development of an energy system corresponding to ZEH (Zero Energy House) is advanced. The authors are developing a hybrid heat source Stirling engine combined heat and power system, which uses solar and woody biomass for a heat source. In this paper, summary of the 1kW solar Stirling power generation system and a solar tracking type collector using the Fresnel lens are described. And heating method of heater and design of solar power generation system are considered.
