Reflector, receiver arrangement, and sensor for thermal solar collectors

摘要

The invention relates to a reflector for uniaxially concentrating thermal solar collectors, comprising an elastic panel and a means that introduces the oppositely directed bending moments from two opposite sides into the panel. The invention further relates to a receiver for highly concentrating thermal solar collectors, said receiver being arranged inside a protective casing, wherein the protective casing is radiopaque and has an opening that is sealed air-tight, through which opening the radiation can penetrate into the interior of the protective casing. One aspect of the invention relates to a sensor for uniaxially and biaxially concentrating thermal solar collectors, said sensor having a hollow body, in which a photoelectric cell is arranged and which has an opening, in which a transparent scattering element is arranged, wherein the outside of the hollow body is reflective to radiation.
