Abstract

A solar tracker is a device that used to track the orientation of Sun that will move from east and west daily and also move depends on the seasonal change.Solar that installed with solar tracker system will minimize the angle of incident between the light from the Sun and the PV solar panel. The efficiency of solar system will increase because the solar tracker increases the amount of electrical energy produced by converting the light energy. In short, the solar system with tracking system is very important a solar power is the best alternative source of energy to produce electrical energy because it is unlimited and eco-friendly. In this project in order to fully utilize solar energy efficiently, the method of tracking the sun is now generally adopted to maximize the output power. Besides, this project introduces the control principle, system hardware composition and control algorithm of the sun tracking system. The dual-axis solar tracking system used power window motor and a linear actuator to achieve both pitch and horizontal moving mechanism to adjust the solar photovoltaic panel azimuth and altitude angle. On this basis, the solar tracking system with high tracking accuracy, simple structure, reliable control, and low energy consumption rate which is able to improves the power output generated of the solar tracker. By comparing the the fixed mounted panel with each different solar tracking method. Which is dual axis solar tracker, single axis solar tracker and dual axis solar tracker with pid controller method we are able to obtain the percentage diffence of 21.30% ,12.92% and 22.98%. The result obtain able to determine that solar tracker is able to generate much more energy compare to a fixed panel.
