ABSTRACT:
Improved solar sensor and tracker apparatus is described in which an extremely low cost high angular accuracy sensor and tracking device utilizing a symmetrical sensor shade and sensor arrangement is described. An improved circuit control for electric motor drive of the tracker apparatus is also described in which a relatively high speed track operation followed by a relatively slow speed homing in motion is automatically provided by the control circuit driving the electric motors.
