For locations beyond the reach of power lines, Conergy solar water pumps offer a clean and simple alternative to fuel-burning generators and windmills. They require no fuel deliveries and very little maintenance. A solar pump produces the most water when it is needed the most - when the weather is sunny and dry. The pumps can operate directly from photovoltaic panels or from batteries that are kept charged by any combination of DC sources.
