Dual Axis Solar tracker using Arduino for Maximum Power Tracking

This paper focuses on a microcontroller based Dual Axis Solar Tracker with a view to grab maximum solar energy. As the tracking system is being used, it greatly improves the power gain from solar radiation. The process of development of solar panel tracking systems has been ongoing for several years now. By considering sun’s movement across the sky during the day, the solar tracking system is advantageous. Proposed dual axis solar tracker tracks the location of the sun anywhere in the sky. For producing the maximum amount of solar energy, a solar panel must always be perpendicular to the source of light. Because the sun moves in two manners such that, throughout the day as well as throughout the year, a solar panel must be able to follow the movement of the sun with a view to produce the maximum possible power.
