Design and Analysis of Solar Water Pumping System

Abstract

According to the current state of the art, stand-alone photovoltaic installations are increasingly intended for water pumping, and have become a very competitive solution for remote areas. Indeed, photovoltaic pumping systems can offer the advantage of the lowest maintenance and the opportunity to save energy. Therefore, the simplest solar water pumping systems are the ones that operate directly when the sun is shining, but the performance of these systems depends on climatic conditions including solar irradiation and ambient temperature. However, in a remote area these installations do not require electrical storage systems despite the various climatic conditions. This work concerns the design, modeling and functional analysis of a photovoltaic water pumping system operating under the sun, with a view to its installation in an isolated area so that the water stored in a tank is consumed in real time or in case of need even if the pumping operation is not operational. The simulation is carried out using Matlab/Simulink environment, to evaluate the pumping installation performances. The simulation results show that the pumping system works as desired.
