Abstract
Analytical study of solar photovoltaic water pumping system can be performed on the basis of technical, economical and environmental phenomenon. Use of solar energy to generate off grid electric power has been enhanced in these days and it is continuously increasing day to day due to the active interest of government and people. Numbers of applications are available in the solar energy field and amongst its various applications solar photovoltaic water pumping system is best utilized for agriculture and community water supply. It has increased agriculture productivity due to the power availability when needed for irrigation. This technology has improved the living standard of farmers and villagers who have not proper electrical supply as per their requirement for water pumping. This technology is helping to complete the mission of government and helps farmers to get water pumping system without any need of grid connection. The use of fossil fuels was common earlier for the pumping system and mostly diesel generator based systems are used which causes emission of CO2 and other harmful gases. Fossil fuels increase pollution and causes global warming, health problems and many more while solar energy based applications are helping to reduce CO2 emission and making a step toward green environment. This manuscript presents study of technical and economic analysis of solar water pumping system useful for various water supply applications especially in agriculture sector.

Summary
Most of the population in developing and poor nations experiences poor water benefits. Farmers are completely dependent on conflicting rainfall and groundwater to satisfy irrigation need of their yields.The source of energy to pump water is a major issue in developing nations. Availability of fuel is an option for water pumping but transportation cost in remote areas makes it very difficult to choose for farmers. Best option for this is renewable energy sources like solar, wind, hydroelectric, Biomass etc. Among these all solar energy is most suitable for irrigation application. There are numerous applications of solar energy like solar pumping system, grid connected system, solar street lights and as solar thermal in heating and industrial processes. Solar photovoltaic panels are used which convert freely available solar energy into direct current (DC) electricity and further this DC supply is used to fulfill the power demand of the system
