Concentrator consisting of aluminized polymeric film stretched over parallel tensioned wires that can be used with or without tracking drive promises to reduce cost of commercial and residential solar heating systems.
An improved solar concentrator is characterized by a number of elongated supporting members arranged in substantial horizontal parallelism with the axis and intersecting a common curve. A tensioned sheet of flexible reflective material is disposed in engaging relation with the supporting members in order to impart to the tensioned sheet a catenary configuration.
