A Review and Implementation of A Sun Position Tracker with A Twin-Axis Control

Abstract

This paper presents operation of twin axis sun position system with solar array. The photo voltaic cell is an device which is employed to convert light energy into electricity by photo voltaic effect the facility is stored by using batteries. this is often one among mostly used renewable source of energy. it's pollution free, causes no greenhouse gases, simple accessibility, convertibility to the electricity and maintenance free. Thanks to its advantages, the system with Light Emitting Diode used for street lighting purpose. A Sun Tracker with a Dual-Axis Control is used to manoeuvre upward or downward to trace the sunshine throughout the day. the automated tracking system is made to regulate the solar array to take care of perpendicular to the sun and to soak up maximum amount of sunshine. These trackers generate 40-45% of power. The working of sun tracking system depends on the sunshine dependent resistors. These resistors are used as sensors which resistance decreases with increase in candlepower. This technique is most reliable, efficient and straight forward in construction.
