Abstract-solar trackers rely on a direct current (DC) motor control circuit to control the movement of the solar panels. Conventional DC motor drivers are used in solar tracking system is not an option for speed and torque control. Why does DC motor fixed speed to either too fast or too slow tracking motion. Usually, the output torque is set to maximum. If the load (weight of solar panels) is small, the maximum torque is underutilized and therefore energy is wasted. So, a fully adjustable DC motor driver for solar tracking system shows great potential for commercialization as much energy efficient DC motor control circuit can improve the overall efficiency of the solar tracker. Fewer solar panels are needed when they are linked to high efficiency solar tracking system, which will be reflected to lower system. Therefore will be improved engine driver cause significant impact the solar energy industry. Proposed DC motor driver is fully adjustable in terms of speed and torque. Speed and torque of the engine is directly proportional to the output voltage and the output current of the DC motor driver, respectively. Adaptive control of the output voltage and current is possible by installing algorithm in microcontrollers of DC motor driver and it can be reprogrammed according to the requirement. Control speed do solar tracking system to track the Sun more accurately and torque control saves energy.
the converter is used to step down the voltage to reduce the rotational speed of the Solar Panel [4].

INTRODUCTION
Solar tracking system is used to track the position of the Sun in order to get the maximum energy of the solar panel is aligned perpendicular to the incidence of sunlight [1, 2, 3, 12, 13]. Solar panels need to move along with the direction of sunlight during the ...
