Abstract: A solar tracking point concentrator for a solar energy system comprises a light weight reflector in the shape of a paraboloid dish having a rim angle of approximately 109.degree., whereby the center of gravity of the reflector mass is coincident with the focal point of the paraboloid. The reflector is supported on a light weight pipe pedestal assembly and controllably driven by a light weight control-drive means so as to be angularly adjustable in both elevation and azimuth to track the sun and efficiently continuously reflect the sun's rays to a heat receiver disposed at the focal point of the paraboloid preferably in a fixed position.
