IMPROVEMENTS IN RADIATION COLLECTORS

摘要

A solar panel is formed with a flow path (11) for working fluid in the form of a thin film, having a thickness of about 5 mm or less. The flow path is defined between an outer transparent lamella (10) having a thickness of about 1 mm or less and an inner backing member which may comprise either a further thin transparent lamella (12) with a radiation absorbent coating (13) in its rear face, or a non-transparent platten (17) made of a radiation absorbing material, in both cases backed by a reflective metal foil (14) and insulating material (16).
