This research deals with comparison between four mechanisms in operating a supposed water pumping system. These mechanisms are PV generator, diesel generator, diesel motor and electrical grid. Referring to the research it is found that PV generator is more feasible than diesel generator where the cost of one cubic meter when using diesel generator is higher by about 80% than its cost when using PV generator. A vertical turbine pump was used instead of submersible one as it can be driven directly by a diesel motor and then the cost of one cubic meter of water is calculated and compared to PV water pumping system but also the last one is more feasible and more economical. When comparing PV generator with grid, the cost of water is very close to each other even that the cost of water by using grid is less than PV. Finally, load matching technique with dual PV water pumping systems is applied depending on the daily solar radiation curve, where the cost of one cubic meter is decreased of about 9% in comparison with one PV generator. Future works aspires to utilize sun tracking in addition to the matched load by PIC control.
