Solar Powered Submersible Water Pumps

Yes, that’s the whole point of every pump you see in this collection. A solar-powered submersible water pump draws directly from DC solar panels. The models we carry accept voltage ranging from 12-300 VDC, and a lot of them can switch over to AC power as a backup if need be.

The main one is that output is totally dependent on sunlight. Flow rates can drop quite a bit if it’s overcast outside. You’ll need a storage tank or battery backup for these types of environments. You should also know that these cost more upfront than your average AC pump, but they pay for themselves in the long run - it’s a great investment. 

That’s hard to say without knowing more about your well depth and water demands. But, the Grundfos SQFlex series gives you the most to choose from - from 3 GPM at 655 feet to 105 GPM at 80 feet. These are some of our best-selling solar water pumps, especially for commercial settings. The Aquatec SWP-4000 is a good option for lower-demand residential wells under 230 feet, though. We also recommend a closer look at the SunRotor and SPFlex models if you want an AC/DC hybrid solution. Ask our team for a tailored suggestion!

You need two numbers - well depth (total dynamic head) and your daily water demand in gallons. You can always ask our customer service team to help you size the right pump for your use case. This is what we do on a daily basis! 

Again, it’s impossible to say without knowing more. It depends on what you’re trying to pump. Some of our smaller models (like the Aquatec SWP-4000) need just 111W. That’s only one panel. Bigger centrifugal pumps from Grundfos could need up to 1,400W or more (4-6 panels).

Flow rates will plummet, so make sure you are storing water in a tank during peak sun to compensate for the lower production rate on these types of days. 

Our deepest-rated solar powered submersible water pump is the SPFlex 4SPF0.8-300 - it can pump up to 984 feet. Grundfos SQFlex helical rotor models reach 820 feet. That’s probably more than you need, though.
