Due to its arid nature and the availability of a large amount of sunlight in the Sahel, water pumping via solar photovoltaic systems can play a very important role in the agricultural and industrial sectors for rural communities in developing countries. However, this type of system could be directly influenced by the variability of sunshine, which fluctuates from day to day and from season to season. To better understand these difficulties, we propose to carry out a theoretical study to improve the performances of a water pumping system comprising a photovoltaic field, an asynchronous motor connected to a surface centrifugal pump and a water reservoir. The aim is to model and simulate the system using Matlab/Simulink software using a dynamic method. This work highlights the evolution of motor pump performance over time, in relation to the intensity of solar lighting. This dynamic method provides a better understanding of immediate changes in performance. The success of this modeling opens the way to practical applications, particularly in remote regions and rural areas where access to water and the electricity grid is limited, environmentally-friendly energy economy.
