Abstracts: The performance of a solar water pumping system is discussed in this paper; the system consists of a photovoltaic (PV) array, a permanent magnet (PM) DC motor and a helical rotor pump. The operation of the PV array is analyzed using PSPICE. The efficiency of the system is improved with a maximum power point tracker (MPPT) and a sun-tracker.
