Solar water pumping system, for low cost irrigation

摘要

The solar water pumping systems are ideal for small/middle farmers to meet their irrigation requirements who do not have access to electric connection and using diesel pump sets. Energy is a key ingredient for the overall development of an economy. India has been endowed with abundant renewable solar energy resource. India receives a solar energy equivalent of 5,000 trillion kWh/year with a daily average solar energy incidence of 4-7 kWh/m2. This is considerably more than the total energy consumptionof the country. Further, most parts of the country experience 250-300 sunny days in a year, which makes solar energy a viable option in these areas. India is large country and the rate of electrification has not kept pace with the expanding population,urbanization and industrialization and has resulted in the increasing deficit between demand and supply of electricity. There is limited availability/access to grid power in rural areas and the farmers have to rely mostly on hand operated and diesel operated water lifting devices/pumps. However, they are very expensive to run. Farmers often run out of money buying fuel to operate their pumps before the crop is ready for harvest. To overcome this problem, solar water pumping system is an answer to the Punjab farmer.
