Photovoltaic (PV) water pumping constitute an innovative solution for sustainable irrigated agricultural in Morocco. The present study treats technical aspect related to actual use of PV pumping systems for drip irrigation in Morocco. A proposition of a management method is done to optimally operate PV pumping system for adequate synchronization between hydraulic yield and actual daily irradiance. The technical study showed that use of small pumps in parallel improved the efficiencies and makes the pumping system running at 100% with the photovoltaic generator without compensation by use of diesel energy as done for hybrid systems. The result showed that it is possible to design more economical PV systems as the maximum peak power demand for each month can carried out using small power pumps in parallel and adjusting switched power with actual irradiance. Using such method of yielding pumping capacity for drip irrigation is of importance to optimize the design of photovoltaic pumping systems in terms of cost and efficiency.
