Solar Tracking System Design and Simulation

Abstract

In daily life, the need of energy resources is increasing every day, so the renewable resources such as solar energy, became an attractive energy source. In Sudan sources of electrical energy are mainly generated from water, another source of energy is solar energy by using solar cells that converts sun radiation to electrical energy that can be used in common electrical application. Solar Cell main problem is the low efficiency of fixed panel and/or low accuracy of being vertical towards the sun, which results into wasting some of the useful energy.This project is concerned with developing a tracking system that tracks the sun from east to west during the day hours vertically to maximize the energy absorbed by the solar panels. The system is controlled by microcontroller which reads values from LDRs and processes the information to move the panel using stepper motor based on LDRs information.
