To increase the efficiency of solar panels, a solar tracking strategy is used by automatically adjusting the angle of the panels throughout the day to directly face the sun, and trackers can generate 20%–40% more energy than statically mounted panels can generate [1]. . An automatic solar tracking system is an approach for optimizing the generation of solar power and modifying the angles and direction of a solar panel by considering changes in the position and path of the sun. This efficiency gain enables faster ROI for large-scale solar projects while optimizing land use. Current-generation trackers enhance performance through three key innovations: 1P systems with ±60°. . Solar panels convert sunlight into electricity, but conventional fixed-tilt tracking systems often operate below optimal efficiency as the sun's position changes throughout the day.
