Two-dimensional Fresnel solar energy concentration system

  • US Patent No. 9175877
  • Issued: November 03, 2015
  • Status: Active
Energy

The present invention provides a solar energy concentrating reflection system comprising multiple arrays of solar reflectors arranged adjacent to one another on a generally planar support structure where each of the reflector arrays configured into a first Fresnel array in a first dimension. Each of the first Fresnel array of reflectors are in turn arrayed and supported in a support frame in a configuration of second Fresnel arrays in a second dimension such that solar energy from the sun is reflected and concentrated to a predetermined focal line. A solar receiver is disposed in the focal line of the configured solar reflectors such that the first and second Fresnel arrays uniformly reflect and concentrate solar energy from the sun onto the solar receiver within the first and second dimensions with a uniform solar intensity profile.
