Only 31% out of 3.5 million hectares of cultivated land is irrigated so far in Nepal; about one-third of that gets irrigation from groundwater. However, the operational cost of groundwater pumping is relatively high, especially when using diesel pumps. Solar irrigation pump (SIP) technologies can be considered as a solution for enhancing access to irrigation with minimal or no operational cost compared to diesel pumps. SIPs use freely available solar energy to pump water for irrigating farmlands, therefore, are very useful in the areas far away from electricity grids.
