ABSTRACT:
Apparatus for tracking the apparent motion of the sun utilizes a plurality of solar cells to generate an electrical signal when exposed to solar radiation. The solar cells are mounted inside a plurality of trough-like shadow boxes which permit exposure of the solar cells to solar radiation only at predetermined angles. The shadow boxes are mounted for concomitant rotation about a vertical and a horizontal axis and are driven by a pair of reversible motors. The motors are controlled by the output of the solar cells and reposition the shadow boxes to shade the solar cells responsive to the apparent motion of the sun.
