The main advantage of using fuzzy controller for instance solar is the reduction of effect of uncertainty in system control. This paper presents a comparative study between two controller’s methods for Maximum Power Point Tracking (MPPT) for photovoltaic (PV) systems which maximizes the power that can be transferred from the PV system to an electrical system. I design and simulate a MPPT controller using FLC in MATLAB/FUZZY TOOL BOX/SIMULINK. The results validate that MPPT can significantly increase the efficiency of energy production from PV.
