Solar Powered Water Pump

In many developing countries of the world animate power and muscle power is still used for lifting water for crop irrigation or for drinking purposes. Both these methods are highly inefficient, time consuming and becoming costlier. The energy requirements of rural people in developing countries are quite low and are met largely by non-commercial energy sources like firewood, agricultural waste and cow dung cakes. The agricultural land is either irrigated by natural means like rains or by using animal or muscle power. The use of diesel or petrol operated water pumping sets or electric water pump is also increasing. With the increase in population, more land is to be brought under cultivation to increase crop production for meeting the demand of food for which water is an essential ingradient. Moreover, in developing countries where 40–50 percent GNP (Gross National Product) coming from agricultural sector alone, more energy particularly for pumping of water for irrigation is required. Efforts are being made in developing countries to provide electricity in rural areas but the progress has been slow mainly due to the reason that it is capital intensive and is difficult to connect remote scattered villages with the central electric grid system.
