Maximization of power from a solar photovoltaic module is of special interest as the efficiency of the solar PV module is very low. A peak power tracker is used for extracting the maximum power from the solar PV module. In the present work we analyze the design and the simulation of the maximum power point tracker (MPPT) for the solar PV array connected to three phase grid. In our studies, we conceived a PV system where the PV generator is the panel NA-901(WQ). The MPPT system has been tested on Solar PV Module (Micro-amorphous silicon thin-film) rated 90Wpeak at 49.3V, 1.83A at 25 degree Celsius and 1000W/m2 (STC). The simulation studies are carried out in MATLAB /SIMULINK.
