Solar water pumps are often used in remote areas where the cost of running traditional water piping is cost prohibitive or you just want to provide water to an off-grid home. Solar water pumping systems are also used to pump water for livestock and crop irrigation.

Submersible Solar Pumps can lift up to 650 feet and fit in a 4" or larger well casing and are used when the water supply is more than 20 feet from the surface. Submersible solar pumps can operate directly off solar panels, batteries, or in some cases, an AC power source.
Surface Solar Pumps are good for applications with shallow wells, ponds, streams or storage tanks. They are best if the water supply is 20 feet or less from the surface. However, once they have lifted that relatively small amount, surface solar pumps can then push water great distances, 200 feet or more!
Linear Current Boosters for Solar Pumps (LCBs) allow the pump motor to run longer during the day by translating additional voltage to necessary current during periods of low sun.
We also offer Pump Accessories such as filters, valves, and strainers, as well as dry run, float switches and more!Selecting the Solar Panels
The solar panels powering the solar water pump are sold separately. Each manufacturer provides a graph or table showing how many watts of solar panels are needed to produce the desired water flow. Once you have selected the appropriate type and size of solar pump, use that graph to calculate the correct watts of solar panels.
The solar pump and the amount of solar panels needed both depend on how many gallons per day (GPD) or gallons per minute (GPM) you want to pump and the vertical head the pump needs to overcome.
Most solar water pumps run directly off solar panels (PV direct) and do not require batteries. Using batteries may complicate an otherwise straight forward application. Instead of storing electricity in batteries to run the solar pump at non-sunny times, most people prefer to store the water in a holding tank. This results in the same effect, water when you need it, with less cost and less complexity.
