Abstract

The solar tracking device disclosed herein is for use on a solar energy collection apparatus and facilitates optimal performance by insuring that the collection apparatus is continuously aligned with the source of the greatest amount of solar flux. The device consists of three photoelectric sensors and a plurality of vanes, each of the photoelectric sensors being connected to a circuit which controls one of three small DC motors, with each DC motor being the controlling means to either increase, decrease, or maintain the speed of the main drive motor which rotates the solar energy collection apparatus.
