Fabrication And Performance of Dual Axis Solartracker System

Abstract

ABSTRACT Nowadays, Solar panel has been used increasingly in recent years to convert solar energy to electrical energy. The solar panel can be used either as a stand-alone system or as a large system that is connected to the electricity grids. The earth receives 84 Terawatts of power and our world consumes about 12 Terawatts of power per day. We are trying to consume more energy from the sun using solar panel. In order to maximize the conversion from solar to electrical energy, the solar panel have to be positioned perpendicular to the sun .thus the tracking of the sun’s location and positioning of the solar panel are important. The goal of this project is to design and automatic tracking system, which can locate position of the sun .The tracking system will move the solar panel so that it is positioned perpendicular to the sun of maximum energy conversion at all time. Photo-resistor(LDR) will be used as sensor in this tracking system. The system will consist of light sensing system, microcontroller, motor system and solar Panel. Our system will output up to 40% more energy than solar panel without tracking system. So this system will help us consume more energy.
