This manuscript details the design and implementation of a solar tracking system employing a proportional-integral (PI) controller within MATLAB/Simulink to enhance the efficiency of solar panels. The system autonomously adjusts orientation of the panels to follow the sun’s trajectory throughout the day, ensuring optimal solar energy capture. The PI controller precisely regulates the movement of the solar tracker by minimizing discrepancies between the actual and desired panel positions. Simulation results demonstrate substantial improvements in energy output over stationary panels, underscoring the effectiveness of the PI-controlled solar tracker. This approach presents a cost-effective and efficient solution to enhance solar power generation, with promising applications in both residential and commercial solar energy systems.
