Experimental implementation of MPPT for PV systems

Abstract

Solar panel efficiency is an essential parameter in determining the cost of converting solar energy into electrical energy. This paper addresses a technique for maximizing energy extraction from photovoltaic (PV) solar systems using power electronic circuits to achieve maximum power point tracking. Design and implementation details are presented, illustrating the perturbation and observation algorithm based on DC-DC power converter. Simulations are done in Matlab/Simulink environments, and experimental implementation is conducted in a developed PV testbed. Analysis of the recorded results reveals the potential of the presented techniques in enhancing the efficiency of energy extraction from PV systems.
