EXPERIMENTAL STUDIES ON HIGHLY CONCENTRATED SOLAR RADIATION BY USING FRESNEL LENS GROUP
With advantages of lower volume, lower weight, smaller focal length and lower cost, Fresnel lenses are suitable for solar radiation concentration, energy control, and system modularization. In this study, a modular device composed of two-stage Fresnel lens is present and its performance is experimentally investigated for different conditions. Facular point image quality of Fresnel lens is investigated by simulation for lens battery design. As for the Fresnel lens with 100mm in diameter, 220mm in focal length, when incident angle is kept within 1°, the focal point will not move out of the receiver domain with the dimension of 10mm*10mm. when coupling with another Fresnel lens of 30mm in diameter, it has found that 50~60％ of the collected solar radiation can transmit through the Fresnel lens group under condition of 1000 suns.
