ABSTRACT:
A solar energy collecting and utilization system is provided which comprises a lens matrix formed by a plurality of lens units disposed in a generally planar array. Each unit comprises a plurality of lenses arranged in a dome-like configuration and having a common focal length. A solar heat collection surface, formed by a thin metallic (e.g. copper) sheet, is shaped to conform to the curve defined by a line drawn through the focal points of the lenses. A viscous liquid (e.g., a vegetable oil) is circulated in contact with the heat collecting foil to extract heat therefrom. A back-up system includes a plurality of infra-red lamps and associated lenses which focus the light from the lamps onto a further heat collecting surface in contact with the circulating, heat extracting liquid.
