Abstract

A system for collecting solar energy and converting it to heat. The system comprises a primary mirror on which the solar energy falls, an absorber to which the solar energy is directed by the primary mirror and a lens located between them. The primary mirror directs the solar energy through the lens, which distributes the solar radiation on the surface of said absorber. The collected solar energy can be utilized directly by concentrating the solar energy on the high temperature side of a delta T converter mounted at or near the focal point of the optical system and/or can be stored in the form of heat in a thermal fluid that can be transported to a location where it is needed and used immediately or stored for later use. Also described are various- systems for utilizing the collected solar energy.
