SOLAR COLLECTOR

摘要

A solar collector comprises a trough-like reflector having opposed front and rear longitudinal sidles, each defining an air-to-solid interface, and an absorber for receiving solar radiation from the reflector, the absorber being disposed at a position that is offset towards one of the front and rear edges from a central position between the edges of the reflector. The reflector includes first and second opposed spaced apart panels, the first panel having a concave profile transverse to its length for concentrating solar radiation towards the offset absorber, and spacer means are provided for holding the first and second panels in a fixed, spaced apart relationship to form a monacoque structure.
