Abstract:
A solar concentrator includes an optical member having a focal point. The optical member is configured and disposed to direct incident solar radiation to the focal point. A support member is positioned adjacent to the focal point of the optical member. A solar energy collector is supported upon the support member. The solar energy collector is positioned at the focal point of the optical member. A base member is positioned in a spaced relationship from the support member. The base member and the support member define a chamber section that is in a heat exchange relationship with the solar energy collector. The chamber section is configured to absorb and dissipate heat from the solar energy collectors.
