Abstract
In this paper, a comparative study is conducted between two MPPT methods: Perturb and Observe (P&O) and Particle Swarm Optimization (PSO) algorithms for photovoltaic (PV) solar energy harvesting. An experiment setup was established using a PIC16F72 microcontroller together with a boost converter to charge a 12V battery from a 12V, 3W PV cell. The system measures both PV cell voltage and battery voltage using resistive voltage dividers and calculates the appropriate PWM duty cycle to harvest maximum energy. In addition to the hardware implementation, MATLAB/Simulink software was used to develop PV models of 50W cells to simulate the P&O algorithm at uniform irradiance and PSO under partial shading and varying irradiance levels. Results demonstrate that although P&O performs well at uniform irradiance (~88% efficiency), it fails to track the global maximum power point (MPP) under partial shading. PSO, on the other hand, successfully determines the global MPP under partial shading conditions, achieving ~95% tracking efficiency. The study validates the feasibility of cost-effective MPPT implementation on an 8-bit microcontroller for standalone solar charger applications.
