Development of Dual Axis Solar Tracker with IoT Monitoring System

Abstract

Despite the fact that solar energy is infinite, harvesting it is challenging owing to panel inefficiency. In many years, the old solar tracking method was normally set where the solar panel does not shift orientation towards the sun. Since the sun change its position with time, hence dynamic tracking system is needed. The aim of this project, to develop a dual solar tracker that can absorb more lights and real-time monitor its performances. By use of four light dependent resistor sensors, the sun position is tracked, and the microcontroller controls the servo motors to align the solar panel perpendicular to the sun. As a result, the dual solar axis tracker can capture 27.4% more solar power compared to fixed tilted axis. With an internet of things integrated to the proposed system, hence enable the real-time monitoring for the solar panel output performance through Blynk application and Thing speak website accessible from anywhere with stable internet connection.
