Abstract
The present invention is a solar concentrator composed of a generally V-shaped trough of reflective Fresnel steps. The Fresnel reflective steps concentrate the sunlight entering the mouth of the V-shaped trough and parallel to its central axis into a central focal area. By disposing a solar energy receiving element at the central focal area of sunlight concentration a preferred embodiment as a concentrating solar energy collector is realized. Various types of solar energy receiving structures are shown that serve to convert the concentrated sunlight into other forms of useful energy to realize the preferred embodiment as a concentrating solar energy collector.
