A solar energy collector comprising a circular paraboloid mirror formed from a plurality of flexible reflective film strips stretched over a plurality of concentrically arranged support rings being arranged to position the film in a circular paraboloid. The support rings are supported by a plurality of trusses. The mirror is pivotally secured to a lower support assembly which is rotatably about an azimuth bearing and rotatable for elevation through a pivot point which passes through the mirror. The support rings are adjustable such that light rays striking the film between the support rings is reflected to the focal point of the mirror wherein a solar collector is located. The solar collector comprises a plurality of helically arranged tubes coated with a black composition of plaster of paris and carbon black to maximize collection of heat to the fluid passing through the tubes. The nest of tubes are hermetically sealed to minimize losses from convection.
