Abstract

The use of solar energy in isolated sites for different applications, such as water pumping, is of primary interest to people in developing countries who do not have safe access to water drinking. But photovoltaic generators have two major drawbacks that are a low yield and a high blow. In order to increase the performance of these systems. Proper adaptation between the solar generator and the load reduces the cost of installation. The choice of an energy system must obey and comply with certain rules. The selected energy system must show as a preliminary its competitiveness with respect to other systems for the same rendered service. The present study have a propose the modeling, simulation, sizing and realization of a photovoltaic pumping system operating over the sun. This system consists of a set of interacting elements; namely the photovoltaic panels, the voltage inverter, the asynchronous motor, the centrifugal pump and the hydraulic circuit.

Highlights

Energy consumption is growing at a rate of approximately 1% per year, and at a rate of 5% per year in developing countries [1,2,3]
The energy demand is increasing every day, and petroleum based fuels are not promoted to compensate that growing demand, mainly because of decreasing world petroleum production and environmental pollution such as greenhouse effect and global warming [4,5,6,7,8]
The results show that most of energy generated from PV array is used by the pumping system and only 11.7% fraction of total generated energy is wasted

Summary

Introduction

Energy consumption is growing at a rate of approximately 1% per year, and at a rate of 5% per year in developing countries [1,2,3]. Water pumping in developing countries is generally dependent on conventional electricity or diesel generated electricity. Solar water pumping system is to reduces the usage of diesel fuel or coal based electricity. The use of diesel based water pumping systems requires expensive fuels, and create noise and air pollution. Environment friendly solar pumping systems require less maintenance cost with no fuel cost [16]. Keeping in view the shortage of electricity in rural villages, PV pumping is one of the most promising applications of solar energy. This technology is similar to any other conventional water pumping system except that the power source is solar energy. This paper discusses about the combined effect of solar power pump connected with the emitter system
