  • Dual-stage parabolic concentrator
    Patent number: 10063184
    Abstract: An improvised Solar Concentrator and Absorber/Receiver Subsystem using a Dual-Stage Parabolic Concentrator for Concentrating Solar Power (CSP) (Thermal) system comprises of two parabolic mirrored reflectors wherein their apertures face each other with their focal point/line and axes coincides with each other, a plurality of absorber tubes/cavities placed on the non-reflecting side of the primary and/or secondary reflectors to carry heat transfer fluid, combined with relevant mechanisms to prevent/minimize thermal loss, mounted on a Sun tracking mechanism. For Concentrating Photovoltaic (CPV) and Concentrating Hybrid Thermo-Photovoltaic (CHTPV) Systems, all or a portion of the reflectors' reflecting and/or exterior surfaces would be covered or substituted with suitable photovoltaic panels.
    Type: Grant
    Filed: November 6, 2017
    Date of Patent: August 28, 2018
    Inventors: Karthigueyane Lakshmanan, Rajaganapathy Lakshmanan
