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 pumping systems are used to pump water for livestock, crop irrigation, and even for simple domestic water supply where a home or town is remote and off the water pipeline.

More Info on Solar Water Pumps

Submersible Solar Pumps 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. They 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.

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.

Circulating Pumps are used primarily in solar water heating applications. AC and DC versions can be seen in the Solar Water Heating section of our website.

We offer Pump Accessories such as filters, valves, and strainers, as well as dry run and float switches and a small selection of submersible wire.

 

How do I choose a Solar Pump and the Solar Panels to power it?

Selecting the Solar Water Pump

Solar water pumps can be used with ponds, streams, or wells (generally 4-6 inch well casings). If the water level is lower than 20 feet and the solar pump will need to lift more than that, a submersible solar pump will work great and can lift vertical distances of up to 700 feet. Surface solar pumps can use suction to draw water vertically about 10-20 feet. However, once they have lifted that relatively small amount, surface solar pumps can then push water great distances, like 200 feet or 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. Call us to get friendly, technical advice to help you design your Solar Water Pumping System.

 

Should I use Batteries with my Solar Water Pumping System?

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.
