The efficiency of photovoltaic pump system (PVPS) varies with the solar irradiation and it is important to select the suitable pump to improve the efficiency of PVPS. Pump with higher head works longer but is in lower efficiency when solar irradiation is powerful in noon. The paper proposes a maximu...
