A Rainy Month Performance Evaluation of Photovoltaic Module and Performance Prediction of the PV Water Pumping Systems Under Soudano Sahelian Climate

The purpose of this paper is to evaluate the energy yield of the photovoltaic module during the worst case conditions in Soudano Sahelian climate in order to predict real time worst performance of a PV water pumping systems in two stations in soudano-sahelian zone of Cameroon. a simple model has been developed with experimental data of electrical energy delivered by PV module for estimating the performance of a photovoltaic (PV) water pumping systems, this work is made possible using 5-min intervals of measured performance data (ambient temperature, current, voltage) for the month of August using the optimum fixed tilt angle of the PV array. The method is validated by predicting the performance of two PV pumping systems installed in an isolated site in Agola and Dorigué. The daily and the monthly flow rate of the systems predicted by the method are evaluated.
