• NUMERICAL ANALYSIS OF COST-EFFECTIVENESS AND PERFORMANCE OF SOLAR WATER PUMPING SYSTEM IN INDIA

Abstract

There are some sources of energy to turn on motors; electric and diesel motors are generally used in irrigation. Solar based water pumping system is a convenient and affordable solution used to solve water shortage problems in India. Due to the constantly increasing cost of fuel or high rate of electricity, pumping of water from surface water and groundwater wells has become extremely difficult for farmers and other water users. This paper analyze the viability of Photovoltaic based pumping system in water irrigation with low cost and high efficiency. Solar water pumping system is environment friendly. This system can provide considerable socio-economic benefits to both at farm level and at national level.  This study evaluates the performance parameters namely speed, efficiency and power factor of motors. The cost of pumping is the deciding factor in the analysis of the costs of water pumping systems. The result reveled that in compare to diesel pump and electric pump, solar pump is proven as an affordable alternative for water pumping system.
