Solar water pumping is the process of pumping water with the use of power generated by sunlight. The advantages of solar water pumping are many. Solar pumping systems are reliable stand-alone systems that require no fuel and very little attention. Generally, when water is needed most, is when the sun shines the brightest. Solar panels generate maximum power in full sun conditions when larger quantities of water are typically needed. Because of this natural matching effect, solar water pumping is an obvious and economical choice over windmills and engine-driven generators for most locations away from utility power.
