In this paper an intelligent method of maximum power point tracking (MPPT) using fuzzy logic control for stand-alone photovoltaic (PV) system has been presented. The PV is composed solar array, buck DC-DC converter, and MPPT controller. Fuzzy controller (FLC) easy to implement, does not need knowledge the exact model system. Simulation results compared with those obtained by conventional perturbation observation (P&O) technique show effectiveness during steady-state varying weather conditions.
