Abstract
An improved solar collector system includes a moveable surface to receive solar radiation. The moveable collector surface is supported by at least one load bearing universal joint. The movement of the collector surface is accomplished by a hydraulic actuated tracking system to enable the collector surface to be oriented toward the sun to achieve maximum solar energy recovery. The hydraulic actuated tracking system includes at least two hydraulic cylinders and pistons whereby the primary piston and cylinder control the position of the secondary piston and cylinder which, in turn, control the orientation of the collector surface.
