Aiming at reduction of the energy consumed in domestic and business use, research of an energy system corresponding to ZEB/ZEH (Zero Energy Building/House) is advanced. The authors are developing a hybrid heat source Stirling engine CHP (combined heat and power) system, which uses solar and woody biomass. This paper describes a basic solar Stirling engine power generation system only with solar energy. The system has a solar tracking type collector which is made by a Fresnel lens. The performance testing which improved heating method in a heater side for characteristic evaluation was conducted, so that about 14 W of electric power output of the Stirling engine generator became possible. However it's lacking in thermal energy collection by the Fresnel lens, also the heating in the heater side of the Stirling engine generator is not enough in direct-heating.
