Solar water pumping systems is a pro-active approach inagricultural applications. The paper presents mathematical model ofPhoto-voltaic(PV)panel, Maximum power point tracking(MPPT)controller considering hill climbing, perturb & observe algorithms,
mathematical model of Brushless direct current (BLDC) motorsimulations. PV panel connected to load with and without MPPTcontrollers are simulated and results are analyzed. The response ofBLDC motor with changing irradiance are simulated and presented.
