Abstract: A solar system with a thin film absorber envelope, so constructed and arranged as to have a peristaltic type action in the direction of flow of fluid passing therethrough whereby to cause bubbles in the fluid to be flushed out of the envelope. The absorber envelope is of relatively thin flexible plastic film with a support arrangement being provided for supporting the envelope at spaced positions such that the envelope is loose and ruffled between the positions. A transverse tension is applied to the envelope at these positions. The envelope is divided into parallel longitudinally disposed channels extending between an input section and output section. The input section includes a manifold coupled to and distributing the fluid to the channels. A venting arrangement is provided in an associated glazing to prevent the temperature between the glazing and envelope from exceeding a value at which the absorber envelope might be damaged.
