Due to variation of temperature and solar intensity, the power output from photovoltaic panel will not be steady. The method of locating a point on IV and PV characteristics of PV panel, at which the output power of PV panel is maximum is known as maximum power point tracking [MPPT]. By the use of MPPT technique, maximum power can be extracted from the PV panel. There are many MPPT techniques such as Perturb& Observe method, Incremental Conductance method, fractional open circuit method and others. In this paper Perturb and Observe method and fuzzy logic controller [FLC] for maximum power point tracking are discussed. The MPP is tracked for varying and constant solar irradiance. The design and performance of P& O method and FLC are analyzed in this paper. From simulation results it is clear that FLC MPPT method is advanced technique which provides better performance when compared with P& O and other MPPT techniques.
