Fabrication and Performance Test Of An Automatic Dual-Axis Solar Tracker

Abstract

Of all the renewable energies, solar energy is the only energy gained its popularity and importance quickly. Through the solar tracking system, we can produce an abundant amount of energy which makes the solar panel’s work ability much more efficient. The main control circuit is based upon Arduino micro controller. Micro controller is controlled this system by programming. Here also use an Arduino Pro Mini, Buck Converter, LDR Sensor, Servo Motor. The main task of this project is that when the sun reflects on this solar panel, it will charge and save its battery. The LDR sensor then senses the direction of the sun and moves this solar panel automatically. We worked with dual- axis experimentally, stationary solar, and single-axis solar experiments to compare, and finally, we found dual-axis efficiency is
