Irrigation in remote areas by Solar Water Pumping System.
Solar Water Pumping System has a long history; so many methods have been developed to pump water with a minimum of attempt. These have utilized a variety of power sources, namely human energy, animal power, hydro power, wind, solar and fossil fuels for small generators.
Solar pumps are used principally for three applications:
(1) Village water supply
(2) Livestock watering
(3) Irrigation
A Solar Water Pumping System for village water supply, a invariable water demand throughout the year occurs, although there is need to store water for periods of low lagging (low solar radiation). Typically in Rajasthan in India the storage would be 3-5 days of water demand. In environments where rainy seasons occur, rainwater harvesting can offset the reduced output of the solar pump during this period. The majority of the 6000 or more solar pumping systems installed to cultivate for villager.
A solar irrigation system needs to take account of the fact that demand for irrigation water will vary throughout the year. Peak demand during the irrigation seasons is often more than twice the average demand. This means that solar pumps for irrigation are under-utilized for most of the year. Attention should be paid to the system of water distribution and application to the crops. The system should minimize water losses, without imposing significant additional head on the pumping system and be of low cost.
