More energy is produced by tracking perpendicular to the solar panel. This requires constant tracking the solar panel to remain aligned to the sun at a right angle to the of the sun’s apparent daytime motion, and hence develops an rays of light. This paper describes in detail the design and automated sun tracking system which carries the solar panel and construction of a prototype for solar tracking system with two positions it in such a way that direct sunlight is always focused degrees of freedom, which detects the sunlight using photocells. on the PV cells [2]. The control circuit for the solar tracker is based on a PIC16F84A This paper is about moving a solar panel along with the direction microcontroller (MCU). This is programmed to detect the of sunlight; it uses a gear motor to control the position of the sunlight through the photocells and then actuate the motor to solar panel, which obtains its data from a PIC16F84A position the solar panel where it can rec
