Energy is the most important factor for the economic development of a country. In order to cope with increased demand of energy, an efficient photovoltaic (PV) power generation system needs to be developed. The efficiency of PV module is very less and it shows nonlinear characteristics due to variation in solar irradiance and operating temperature. The efficiency of the PV system can be improved by operating the system at its maximum power point (MPP) which can be accomplished by adopting maximum power point tracking (MPPT) techniques. This paper addresses implementation of an fuzzy logic based MPPT method. MPPT tracking mechanism such as Perturb and Observe (P&O) MPPT algorithm and Fuzzy-MPPT (FMPPT) for PV power generation system are implemented in this work. The performance of FMPPT is compared with that of P&O MPPT. Since FMPPT can handle nonlinearity very well and can track the MPP more precisely and rapidly, it provides better performance than P&O technique in tracking of MPP.
