Abstract
A low-cost solar collector employs a concave reflecting surface and a convex reflecting surface configured as a cylindrical Cassegrain optical system with planar symmetry to concentrate sunlight for photovoltaic solar panels. The collector achieves high concentration factors exceeding 20× and maintains focus of concentrated sunlight on the photovoltaic cells using a simple mechanical means to rotate the collector. A plurality of solar collectors is arranged in parallel in a conventional solar panel form factor and driven by a single drive system to maintain the sun continuously in the plane of symmetry of each of the solar collectors that comprise the solar panel. This reduces the area of photovoltaic cells required to convert a given quantity of light energy to electrical energy. Cost of electrical energy generated is reduced significantly because the cost per unit area of the solar collectors is much less than the cost of photovoltaic cells.
