“…Solar pumps have been used in agriculture since the late 1970s (Parker 1991), but PVpowered water pumps are increasingly seen as the "harbinger of a new era in water provision for rural and developing communities" (Short and Thompson 2003). Solar-powered pumps exist in three main categories: concentrated solar, solar thermal and PV.…”

Research ReportsThe publications in this series cover a wide range of subjects-from computer modeling to experience with water user associations-and vary in content from directly applicable research to more basic studies, on which applied work ultimately depends. Some research reports are narrowly focused, analytical and detailed empirical studies; others are wide-ranging and synthetic overviews of generic problems.Although most of the reports are published by IWMI staff and their collaborators, we welcome contributions from others. Each report is reviewed internally by IWMI staff, and by external reviewers. The reports are published and distributed both in hard copy and electronically (www.iwmi.org) and where possible all data and analyses will be available as separate downloadable files. Reports may be copied freely and cited with due acknowledgment. About IWMIIWMI's mission is to provide evidence-based solutions to sustainably manage water and land resources for food security, people's livelihoods and the environment. IWMI works in partnership with governments, civil society and the private sector to develop scalable agricultural water management solutions that have a tangible impact on poverty reduction, food security and ecosystem health.

“…designed and developed a solar photovoltaic pump operated drip irrigation system for growing plantations in and region considering different design parameters, like pumps size, water requirements, and the variation in the pressure of the pump due to change in irradiance and pressure compensation in the emitters [2]. Solar powered water pumping has the potential to bring sustainable supplies of potable water to millions of people in developing countries [3]. Performances of a photovoltaic pumping system based on an induction motor are degraded once insolation varies far from the value called nominal, where the system was sized [4].…”

“…The Nile River is the almost exclusive source of freshwater to meet all needs; agricultural, industrial and domestic. Egypt is facing increasing demand for water from these sectors at a time when supply is fully allocated: Egypt's share of water from the Nile has been fixed at 55.5 billion m 3 per year since the 1959. Agricultural production in Egypt occurs exclusively in the Nile Delta and a narrow corridor along the Nile River [1].…”

Photovoltaic now used in new irrigation system as a source of renewable energy to run the pumps. It's can be used in remote areas, which it's very difficult and more expensive to establish power stations or to install transmission lines to connect these areas with the electrical grid. Surface pump can be used in modern irrigations systems and connected to PV power supply to save energy and water. In this paper a system contains 10 hp surface pump and 15 kW PV system uses to drive the pump unit are studied. The paper investigates mathematical models for surface PV pumping system component. The performance of this system is studied by using this mathematical model during a long time, and the effect of solar radiations values on the system performance is estimated. The paper introduced a simulations and experimental results of the PV pumping in daily hourly average during one year. A good agreement between the simulations results and experimental results are found. The paper investigates the overall performance foxing on the water flow rate values obtained from the unit during one year. Also the electrical power quality analysis of the AC voltage feeds for the pump unit are measured and calculated. Due to solar radiations variation during day hours, and during different months the electrical performance such as; voltage current, power and also harmonic contents is changed depends on the values of solar radiations. The electrical signals and power quality are measured on the field by using power quality devices in different days and statues of operations. The results showed that; during low radiations periods the voltage and frequency are varied in a constant relation to reduce the pump speed and hence reduce the water flow rate to be proportional to input energy come from the PV panels. In case of high solar radiations the inverter runs the pump at constant frequency values depend on pump specifications. And during clouds occurred the system is stopped.

“…Meah et al (2008) discussed some policies to make solar photovoltaic water pumping (SPVWP) system an appropriate technology for the respective application region as it has proved its aspects technically, economically, and environmentally in developed countries. Short et al (2003) investigated some of the issues involved in solar water pumping projects, described the positive and negative effects that they can have on the community and proposed an entirely new type of pump, considering the steps that could be taken to ensure future sustainability. Badescu (2003) analyzed the operation of a complex time dependent solar water pumping system consisting of four basic units: a PV array, a battery, a DC motor, and a centrifugal pump.…”
