Water Pumps

Many remote homes require the ability to supply water under pressure and on demand, whether from a lake or well. This may be direct to the house and stored under pressure or to a raised tank or water tower in order to create passive pressure.

Both can be hard on your battery bank, although water pumping to a water tank could be more effiencent via a dedicated water pump to move a large amount of water, without killing your battery bank. DC pumps are more efficient than AC pumps, but AC pumps may be less expensive and are more readily available.

Submersible Pumps

Submersible pumps are generally sized for shallow or deep well pumping, where the vertical draw and ammount of height to be pumped is important. Lake pumps or well pumps to large storage tanks is generally about moving a large amount of water, over a longer distance but a slower speeds.

Surface Pumps

Surface pumps are less expensive than submersibles. They need protection from exposure to the elements. They can draw water from a shallow well or tank and push it through relitively short pipelines to fill a storage tank or to pressurize it for immediate.

Sizing

In order to properly size a solar water pumping system, careful planning must be adhered to. It is difficult to accurately rate a pump as the harder a pump has to work the more current it will draw. In a system with an accumulator tank, the pump will often be drawing 3 times the current towards the end of the pressurization cycle.
