Photovoltaic Water Pumps

Posted on Oct 25, 2011

Short technical brief by the GTZ on photovoltaic pumping systems. In many developing countries, the inadequate supply of drinking and irrigation water is a severe problem. In rural areas with no access to grid power, national water authorities and private farmers have to rely on hand pumps and diesel-driven pumps, many of which are out of service due to technical defects or a lack of fuel. As a rule, hand-operated pumps are the least-cost option for low consumption rates and low pumping heads. If hand pumps cannot satisfy the demand, diesel driven pumps are commonly used for drinking and irrigation water supply. These pumps stand in competition with photovoltaic water pumps (PVP), which present themselves as a reliable and environmentally-sound alternative means of water delivery.
