Dual Axis Solar Tracking System using 5-LDR sensor

Abstract

Limited non renewable energy resources and increasing power demand is a major topic of concern around the world. In recent decades, renewable energy resources are widely used in order to satisfy the increasing power demand and to minimize the damage to the environment. The aim of the paper is to present a unique solar tracking technique which can be used to extract maximum power from the photovoltaic cell by using a close loop control system along with a 5-LDR sensor module which is strategically designed to generate feedback signal in order to track the sun’s azimuth and elevation angle. By using the close loop system the tracker will be able to keep the solar panel align to the sun light irrespective to the change in the intensity of light.
