>Solar Water Pumps
Solar water pumps are used throughout the world for a number of innovative applications. If you are in a remote area and the cost of running traditional water piping is cost prohibitive, a solar water pump may be the right solution for your water supply needs. Additionally, if you are looking to install a Solar Water Heating system in your home, you will want to use the right solar water pump. Solar water pumps are used for pumping water for livestock, crop irrigation and even simple domestic water supply where a home or town is remote and off the water pipeline. That means you can pump water even when the electricity goes out!
- Circulating Pumps: Used primarily in solar water heating applications. These pumps run directly from a small solar panel. No battery required. Submersible Pumps: Lift up to 650 feet and fit in a 4" or larger well casing.
- Submersible pumps are used when the water supply is more than 20 feet from the surface. They can operate directly off solar panels, batteries or in some cases an AC power source.
- Surface Pumps: Good for applications with shallow wells, ponds, streams or storage tanks. Best if water supply is 20 feet or less from the surface.
- Linear Current Boosters For Pumps: LCBs allow the pump motor to run longer during the day by translating additional voltage to necessary current during periods of low sun.
- Pump Accessories: We offer filters, valves and strainers as well as dry run and float switches and a small selection of submersible wire.

More info on Solar Water Pumps
Selecting solar pumps and solar panels to power them. Solar panels to power the water pumps are sold separately from the pumps. Both the pump and the amount of solar you need depend upon how much water you are trying to pump in a day (in GPD or GPM) and the vertical head the pump needs to overcome. Surface pumps can use suction to draw water vertically about 10-20 feet. However, once they have ‘lifted’ that relatively small amount, surface pumps can then ‘push’ water great distances - like 200 feet or more! If the water level is below about 20 feet, and the pump will need to lift more than that, a submersible pump will work great and can lift vertical distances of up to 700 feet. Once you have selected the appropriate type and size of pump, use the graph that accompanies the pump in order to calculate the correct number of watts of solar. Each pump manufacturer provides a graph or table showing how many watts of solar are needed for the specified voltages in order to produce the desired water flow.

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 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.
