A Microcontroller Based Dual Axis Tracking System for Solar Panel

Solar energy is one of the most promising renewable energy resources that recently have become broader in current technology. This paper presents the technique how Ohm's law and power equation applies to generate more energy from solar photovoltaic (PV) panels. To implement automatic dual axis and a polar single axis solar tracker system is used. It contains a locked vertical axis and a flexible horizontal axis, which is regulated by a motor. To get the maximum power output and highest efficiency, trackers always track the sun and change panel position accordingly. The tracker automatically changes its position after every 2 to 3 degrees of misalignment, to prevent the power loss created by running motor continuously. The light intensities of both sides were compared by the sensors and move the panels towards the light. The panel continuously moves until the tracker detects the equal light falls on both sides. This project helps to improve the solar irradiance of the panel.
