The maximum power point tracking (MPPT) method is usually used in photovoltaic (PV) systems to increase the electric energy production in a photovoltaic generator (PVG) and reduce the PV array cost. The output of the photovoltaic (PV) system depends on the temperature, solar radiation, and impedance of the load. The value for the maximum power point (MPP) is not constant. The principle of this technique is to maximize the electric energy production of a photovoltaic generator (PVG). In this paper, we present à comparative simulation study of two important MPPT algorithms incremental conductance (INC) and perturb and observe (P&O). using the MATLAB/Simulink for performance evaluation by a 50W photovoltaic (PV) array. Some of the important parameters such as voltage, current, and output power of each method are traced for both algorithms. It is demonstrated that the incremental conductance-based MPPT tracking provides more accurate results in less time than the P&O algorithm-based MPPT.
