Abstract:

The increasing significance of photovoltaic (PV) power systems stems from the fact that most renewable energy sources are clean and virtually limitless. These systems are intricately designed to harness solar energy with utmost efficiency. Maximum Power Point Tracking (MPPT) is a pivotal technique to optimize power extraction across diverse conditions. This paper introduces a solar charge controller with a PIC microcontroller that controls the circuit and generates PWM signals to regulate the DC-DC converter. An innovative facet of this system lies in integrating a Wi-Fi module for data storage, enabling the transmission of solar panel data to the cloud. Notably, this work introduces a novel approach utilizing a Fuzzy Logic Controller (FLC) for MPPT, enhancing the precision of power tracking from the solar panel. To validate the efficacy of the proposed MPPT controller employing fuzzy logic, a simulation model is simulated using MATLAB. Furthermore, the practical implementation of the entire hardware setup substantiates the feasibility and functionality of the developed system.
