The study compares the relative error of two control systems in photovoltaic power plants: the MPPT based on an adaptive PID and the PWM controller. The objective is to evaluate which of these systems best optimizes solar energy conversion into electricity, especially in installations that include batteries as load. Using Matlab/Simulink, both controllers were modeled and simulated to observe their behavior under different solar irradiance and climate variability conditions. The analysis focused on energy efficiency, response time, and the ability of each controller to track the maximum power point (MPP) of the photovoltaic system (PV). The results indicated that the adaptive PID-based MPPT controller outperforms PWM regarding MPP tracking accuracy and energy efficiency, adapting better to environmental fluctuations. This study suggests that adaptive PID controllers can extend battery life and improve system stability under changing conditions.
