Solar Powered Water Pumps

Pumping water is a universal need around the world and the use of photovoltaic power is increasing for this application. PV powered pumping systems offer simplicity, reliability, and low maintenance for a broad range of applications between hand pumps and large generator driven irrigation pumps. The solar PV powered water-pumping system (DC Surface suction, DC floating, and DC or AC submersibles) can offer a veritable panacea to the problem of finding power to pump water for irrigation. The system for solar pumping depends on the nature of the well: deep well, bore well, open well etc.

Regardless of the type of pump used, water is usually stored in a tank or reservoir for use at other times. Most pumping systems do not include batteries for on-demand water. However, batteries are sometimes used in systems where pumping time must be controlled because of low water demand or low source capacity.

The problems with the grid-powered pumping systems are: 

• Demand for electrical energy far outstrips supply, and the gap continues to widen

• It is proving increasingly difficult for the government  to continue subsidizing the rising costs of generation, transmission and distribution losses, pilferage, etc. The loss of revenue to the government is colossal.

• The costs and tariffs of electricity continue to rise – the marginal farmer is unable to pay for the electricity)

• Grid power is unreliable and of poor quality, often leading to motor burnouts at the tail end.

• In a coal-fired thermal generating station, 1 kWh of electrical energy generated translates to 11.2 tonnes of carbon dioxide emission a year.
