Performance of Pumping System Under Partial Shading

The implementation of photovoltaic pumping systems is becoming more and more widespread, particularly for isolated sites. However, it is well known that the performance of these types of installations depends, to a great extent, on climatic changes, in particular temperature and Irradiation. Therefore, as the phenomenon of shading has a direct consequence on the impact of weather conditions on photovoltaic panels, this study aims to optimize the operating conditions of a photovoltaic pumping system.Analysis of system performance under the MatLab / Simulink software environment has shown that optimization techniques force the system to operate at its optimum speed.
