Solar Tracking Systems and A Two-Axis Active Prototype With Stepwise Movement

Abstract

In this work, criteria for a two-axis solar tracking system that provides a higher voltage and power output than a fixed solar panel, are determined and a prototype is realized with stepwise movement. From that point on, to design a practical solar tracker, extensive research studies were conducted which resulted in determination of optimal techniques and components. As a result, by using a small scale solar panel, servo motors as drive elements, Arduino processor as the controller, and a wireless transmitter that transmits voltage feedback to the controller, a two-axis active solar tracker is developed which moves in pre-determined steps
