Currently, one of the most efficient and cleanest forms of renewable energy source for effective power generation is Photovoltaic (PV) source. It is because of its cheapness, almost free maintenance cost, friendliness to the environment etc. However tracking the sun energy with the solar panels for effective utilization of its energy still pose a major challenge to researchers. Hence tracking these energy is very important. The paper is on simulation of MPPT using P&O and INC methods. Mathematical model of 100KW PV system was developed using Matlab M-file. Both models were designed and simulated using MATLAB/SIMULINK. It is shown that PV system output power increases with rise in solar irradiation and in lower cell temperature. Therefore, solar cell performs better in warm environment than cold environment. The P&O gives the best duty cycle as compared to constant time interval control in getting the PV system’s highest power and the INC method extract a high maximum power than P&O. Both popular MPPT methods were used in the simulation which was controlled by the signal builder and the results displayed. It was observed that INC MPPT has better performance than P&O algorithm. The voltage obtained from the panel system is increased by the DC-DC boost circuit with a load resistance connected to it. It is recommended that the MPPT The system should consist of fractional, three-point, temperature-based MPPT for more effective and improved comparison. Moreso the perturb and observed method should be improved on by varying of the irradiance to maintain an increase constant voltage.
