7 October 2014 A small-scale concentrating solar thermal system
Author Affiliations +
The initial prototype design and characterization of a small-scale concentrating solar thermal system will be presented. A large Fresnel lens, with an area of 0.77 square meters on a two-axis tracking mount, is used to concentrate the solar energy and focus it to an area of a few square centimeters. The system design and the first prototype testing will be discussed. By leveraging concentration to achieve the maximum solar-to-thermal energy efficiency and low cost, the system is unique compared to currently available residential hot water systems.
