Irrigation is the most important input in agricultural production process. Huge investments are made for creation and maintenance of irrigation infrastructure. Hence water use efficiency is an important attribute. The different energy sources for pumping water assumes economic importance not only for the farmers but to the country as a whole. An attempt is made in this paper to understand the life cycle cost of different pumping systems for Solar Photo Voltaic pump system, Electric driven pump and diesel driven pump over the life period. Comparative evaluation of the life cycle costs of the three alternate systems for water pumping indicated better economic feasibility of Solar Water Pumps compared to the Electricity and Diesel based water pumps. On the other hand, the ease of maintenance and longer life period of the solar water pumps are the major reasons for their promotion and adoption apart from being a source of renewable energy. The analysis also indicated that the solar water pumps are economically feasible even without the subsidy extended by the Government. The major issue in adoption of solar technology is higher initial capital investment compared to the other two options and this issue needs to be addressed by the Government through ease of credit with long term repayment options at a subsidized rate of interest.
