Low Energy Solar Pump

What is LE-solar pump?

Low Energy Solar Pump

 Why the need for LE-Solar Pump?

Nepal is an agricultural country with about 28% of total land area found arable. 65 % of total population is dependent on agriculture as main source of income and agriculture contributes to one third of national economy. However due to difficult land topography, limited land, traditional farming, lack of infrastructure and technology, energy crisis, climate change and overpopulation the sustainable development of this sector is hindered. More than 40% of population is below poverty line. Especially the lower class farmers are facing great strategic problems. The productivity and economic benefits from this sector has not been satisfactory Irrigation is the basic infrastructure for agriculture development but only 10% of total arable land has proper irrigation facility. The farmers entirely depend upon monsoon rain for irrigation. In terrain region which is nation's most fertile land there are places where water is available at not very far distance from arable land but due to lack of proper tools farmers have to carry water for irrigation with great difficulty.

The situation is not much different in mountain regions as well. Due to lack of proper technology water at nearby places has to be carried in vessels with great difficulty for irrigation purposes. In hilly region carrying water uphill is very tedious job but people of these regions are faced with the problem to carry water not just to meet daily needs but for irrigation purposes as well.

In terrain region underground water is readily available in sufficient amount to fulfill the drinking needs as well as irrigation however due to the lack of proper pumping mechanism people of these regions are living in water scarcity. Water from wells and ponds is fetched for daily use in most parts, children's who go to fetch water from wells are falling into wells and on way home and hurting themselves due to difficult land topography. The water so fetched has lot of sediments and impurities as the whole water source is disturbed with vessels used to fetch water so the quality of drinking water is also poor.   Parents are forced to send their school going children to fetch water for daily requirements when they should be going to school this is hampering these children's chance at a better future.

In parts of the country where national electricity grid has not reached yet solar panels are used for electrification purposes, the energy potential of these panels is being wasted as they are used for about 2/3 hours during night hours for electrification purposes only. These solar panels could be used to pump water from nearby sources for drinking purposes and also for small to medium scale irrigation purposes.
