N2 - In a photovoltaic water-pumping system, the solar cell array is usually designed to power a single motor-load-pump. Several water pumping systems of the same or different types that are in close proximity to each other may be powered by separate solar cell arrays (sources) for each one, or alter natively, by a common solar cell source for all the water pumping systems. The purpose of this study is to introduce a procedure for comparing the performances of these two setups. One system includes a permanent magnet DC motor and a volumetric pump, and the other a permanent magnet DC motor and a centrifugal pump. The comparison was also done for the same systems when a maximum-power-point-tracker (MPPT) is included for both the separate and the common solar cell source. The study shows, for example, that in systems not including MPPT’s the total performance of the two motor-pumps in the common source system is improved as compared to the performance of the two motor-pumps when they are powered separately by individual sources.
