Enhancement of Solar Output with Dual Axis Solar Tracker using Arduino

Abstract

Collection of Sun's energy at the maximum level can be simply possible by using the tracking system. The proposed network aims in tracking the direction of highest radiation angle of sun's beam. This is done by fixing the panel with the geared motors embedded with sensors and controllers. Two servo motors are controlled by the c program embedded in the arduino controller and the LDR sensor. This method gives high output when working with tracker than without tracker and gives high efficiency. This can be applicable in simple low voltage systems where the complex techniques and algorithms cost more. The output power of the system with tracker and without tracker was studied. The voltage and current characteristics of the system with tracker and without tracker for different time period from morning to evening was found and drawn.
