  • Patent number: 6384320
    Abstract: The invention relates to a solar compound concentrator of an electric power generation system. A compound parabolic concentrator (CPC) is mounted under an acrylic concentrating fresnel lens that concentrates the intensity of sunlight to five to ten times above normal level. Then the focused sunlight is further concentrated twenty to fifty times by the CPC collector. The intensified sunlight is focused on the bottom of the CPC. The high mirror quality of CPC allows 98% of the reflected rays to be incident on the bottom of the CPC. A cermet coating is spattered onto the top of a stainless steel heat pipe (heat exchanger) allowing for an absorptivity of 96%.
