A single-axis Sun tracker to follow the position of the sun was designed and constructed and an experimental investigation was carried out on photovoltaic power output through the single axis automatic controlled solar tracker. This paper presents the design of an Automatic Solar tracking system to track Solar PV Panel according to the direction of beam propagation of Suns radiation. The entire tracking system consists of sensor with ADC, control circuits to motor drive with control software, and bearing with supports and mountings. The controlling motion for PV panel has been provided by...
