Modeling and Performance of an IntegratedSolar Water Pumping System

Abstract

Solar water pumping systems provide a proper energy solution especially in rural and isolated areas where the traditional sources of power (electricity or diesel) are unavailable or very costly. Solar energy is available with abundant quantities of daily irradiance, and it is a clean and carbon free source of energy. The present work furnishes a mathematical model and performance evaluation of an integrated solar water pumping system for different water demands through a comprehensive design tool simulation program prepared and designed by the authors. The model calculates the solar radiation data for the selected cite. The simulated model, based upon the solar radiation values, can provide, for the specified water demands, the related hydraulic pump electric power for the desired pump total dynamic head, the required PV peak power and its related area requirements, and the corresponding total cost of the system components in Euro. The present program is universal and can be used to design solar water pumping systems anywhere in the word. The present results are for Cairo Egypt, for water demands range from 50-300 m3/ day. Egypt enjoys an average value of solar radiation of 5.5 kWh/m2/day. The present research offers a good accurate quick tool for designers, users, and buyers of such systems...
