Solar energy collection system

摘要

A solar collector of the CPC-type is described. The collector is provided in modular form with a plurality of elongate forming reflectors housed within an outer metal tray and a glass cover. An absorber tube passes sequentially through the reflectors and is normally located at the focus of the reflectors to permit fluid passing therethrough to be located. To provide on-going heat regulation and shut-down capability, the absorber tubes are movable out of the reflector focus by an automatic device which senses excessive temperatures and effects the defocussing movement in response thereto.
