Solar Energy Simulation of Fresnel Lens Concentrated System for Thermal Electric Generator

Abstract

The expensive manufacturing process and low efficiency at high working temperature of Solar cells necessitate the need for an alternate solar energy generation system. Solar concentrated thermal electric system has proved to be a promising candidate for a reliable energy conversion system. In this study, Fresnel lens had been chosen as the concentrating medium due to its low weight and easy installation. Optimum design of the Fresnel lens setup inclusive of the ability to track during an entire solar day has been devised. Standard TEG of material bismuth telluride was considered for energy harvesting from concentrated solar irradiance, and complete cost analysis was performed, and payback period of the proposed model was found out to be considerably less compared to conventional solar panel system.
