Dual Axis Sun Tracking System Using a Microcontroller and a Stepper Motor

Abstract

This study pursuit develop solar energy systems in the light of technological advances to develop these systems, especially those moving (solar Tracking) to take advantage of sunlight for a longer period. The Objective of Thesis is to find a design of the sun Tracker with two axes follow the movement of the sun throughout the sunrise to take advantage of the rays and solve the problem of environmental factors and the alternation of night and day to produce the greatest amount of solar energy. The circuit of the solar tracker system is dividing into three sections. Firstly, there is the input stage that is composed of sensors and potentiometers, secondly a program in BASCOM software in the microcontroller and lastly the driving circuit that has the stepper motor. And the main results are as follows: • The study obtained on a model to track the sun in two directions (East, West), (North, South) using the microprocessor and step motor. • Solve the problem of different classes and the factors that affect the natural rays fall on the cell. • Solve the problem of stopping the cell at night and daytime running system
