In the present study, the economics of water pumping by different methods are discussed. The methods investigated are the diesel generation system (DGS), the photovoltaic generation system (PVGS), the mechanical wind pumping system (MWPS) and the electrical wind pumping system (EWPS), The results from the sites studied revealed lower costs for both the photovoltaic and mechanical wind pumping systems than diesel generation, while higher costs were noted for the electrical wind pumping system, The results of this study also showed that at low capacities it is more economical to use PVGS than other methods.
