What is Solar Tracking System in MATLAB Simulink For Maximize Solar Panel Output?
Solar Tracking System in MATLAB Simulink For Maximize Solar Panel Output is a MATLAB-based technical project and simulation model. A Solar Tracking System is designed to maximize the energy captured by photovoltaic (PV) panels by continuously adjusting their orientation to follow the sun's movement throughout the day. Compared to fixed solar panels, solar tracking systems significantly improve energy generation, making them suitable for residential, commercial, and utility-scale solar power applications. In this MATLAB Simulink tutorial, we develop and simulate a complete solar tracking system capable of automatically adjusting the panel's tilt and azimuth angles. The model includes solar irradiance calculation, sun position estimation, tracking controller, servo motor actuator, photovoltaic array, Maximum Power Point Tracking (MPPT), DC-DC converter, and performance analysis. The simulation compares the output power of a fixed solar panel with that of a tracking system under varying environmental conditions.
