Study on a 1kW Class Stirling Engine Solar Power Generation System

~Development of a Solar Collector Using Fresnel Lens~

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 CHP (combined heat and power) system, which uses solar and woody biomass for a heat source and supplies power generation and warm water. This paper describes characteristics of a solar tracking type collector for 1kW class Stiring engine using the Fresnel lens. The test results of the solar collector with a square and a circular concentrating area are presented. The latter are improved in an absorbed heat efficiency.
