Abstract


A complex set of factors including global warming, competitive land use and lack of basic infrastructure is creating new challenges for the vast agrarian population in India. The ever increasing mismatch between the demand and supply of energy in general and electricity in particular, is posing challenges to farmers located in remote areas (Shah, 2012). The scarcity of electricity coupled with the increasing unreliability of monsoon rains is forcing farmers to look at alternate fuels such as diesel for running irrigation pump sets. However, the costs of using diesel for powering irrigation pump sets are often beyond the means of small and marginal farmers. Consequently, the lack of water often leads to damaging of crops, thereby, reducing yields and income. Hence, using conventional diesel powered pumping systems poses an economic risk to the farmers.Environment-friendly, low-maintenance, solar photovoltaic (SPV) pumping systems provide new possibilities for pumping irrigation water. However, they constitute a rather unknown technical option,especially in the agricultural sector. Thus far they have not yet been seriously considered in agricultural planning in the country (WISE, 2011).
