In this paper, the authors present the design, construction and also investigate an experimental study of a two axis (azimuth and Polar) automatic control solar tracking system to track solar PV panel according to the direction of beam propagation of solar radiation. The designed tracking system consists of sensor and Microcontroller with built in ADC operated control circuits to drive motor with control software, and gear-bearing arrangements with supports and mountings. A digital program operates the designed Sun tracker in the control system. Two steeper motors are used to move the system panel, keeping the sun's beam at the center of the sensor.
