Solar water pumping systems can be used for many pumping applications, and should be considered for replacing generators and power lines extensions. Unlike generators solar water pumping systems do not require trips for refueling or constant maintenance. The longer the sun shines the more water the solar system pumps. When it's cloudy, they pump less water but often you need less water when it is cloudy.
Conventional AC pumps can pump large volumes of water in very short time; also consume a large amount of energy to do that. Unlike AC pumps, solar pumps move smaller volumes of water but can operate all day, as long as the sun shines, making more efficient energy use.
