Abstract: An automatic solar collector system useful for heating and storing a heating fluid such as, for example, water. The automatic solar collector system of this invention is characterized by its construction including a photo cell-actuated hydraulic cylinder whereby the collector panel may be positioned at an angle to focus the sun's rays onto the fluid conduit disposed within the collector panel. Overall operation of the automatic solar collector system of this invention is regulated by a clock timer, and the entire system is essentially self-contained so that it may easily be moved from one location to another, or put in parts to be attached to a home or a building with the tank and controls below the roof.

Abstract: A solar panel unit for heating circulating fluid has a plurality of preferably rectangular lenses for focusing and concentrating the sun's energy onto a heat-absorbing body through which a heat-exchange fluid is circulated.
