Design and Implementation of Maximum Power Tracking System According to the Sun Direction (Model Sun Flower)

Abstract

Solar energy systems have stood out as a viable source of renewable energy over the past two or three decades, and are now openly used for a variety of industrial and domestic and medical applications. Improvement in the performance of a solar tracking system during summer was found to be as much as 30% for higher elevation angle and 60% for lower elevation angle. Based on the developed tracking algorithms, further it was shown that the amount of solar energy captured by a tilted collector could be increased by more than 35% by adjusting the tilt angle on a daily or monthly basis. This project is designed with AT89S52 MCU.  Depending upon the light falls on LDR 3mm and 20k ohm the data will be read by the Micro-controller and the direction of the motor will be changed, with this direction the Solar panel which are fixed to the stand will also rotates to obtain the maximum sun rays. This project uses regulated 12V and 500mA power supply. 7805 three terminal voltage regulator is used for voltage regulation; Bridge type full wave rectifier is used to rectify the Ac output of secondary of 230/12V step down transformer.
