Solar Panel Tracker System Using GPS Technology

Abstract

This article provides a solution to the problem of not improving three-dimensional systems with light sensors in tracker systems for solar panels, due to the inefficiency of operation in cloudy weather, with an increase in precipitation and contamination of photodetectors. The paper shows the calculation of the position angle of the tracker system relative to the changing position of the sun. The GPS system is able to automatically determine the location of the solar panel (latitude, longitude), then the microcontroller with the developed program performs a mathematical calculation, and the system automatically adjusts the solar panel to the sun. Thus, the need to use a photo sensor is eliminated, since the system automatically determines the optimal angle between the sun and the solar panel.
