  • Linear fresnel solar arrays
    Patent number: 8807128
    Abstract: Disclosed herein are examples and variations of solar energy collector system comprising an elevated linear receiver (5) and first and second reflector fields (10P, 10E) located on opposite sides of, and arranged and driven to reflect solar radiation to, the receiver (5). Also disclosed herein are examples and variations of receivers (5) and reflectors (12a) that may, in some variations, be utilized in the disclosed solar energy collector systems.
    Type: Grant
    Filed: August 27, 2008
    Date of Patent: August 19, 2014
    Assignee: Areva Solar, Inc.
    Inventors: David R. Mills, Philipp Schramek, Peter K. Le Lievre, David B. Degraaff, Peter L. Johnson, Alexander Hoermann
  • Integrated solar energy receiver-storage unit
    Patent number: 8378280
    Abstract: Receivers for use in solar energy collector systems and solar-powered electrical energy generating plants are provided. The receivers comprise a solar radiation absorbing core that converts absorbed solar radiation to thermal energy. The core comprises a refractory material to allow the receivers to operate continuously at high temperatures reached by absorbing concentrated solar radiation. The thermal energy so generated in the core may be stored in the receiver for a transitory period, or for a more extended period. Receivers may comprise one or more fluid channels in and/or around the core for conveying a working fluid to facilitate extraction of stored thermal energy from the core.
