America's #1 Most Trusted Solar-Powered Water Pump

RPS Solar Pump Kits are for people that believe in getting the job done themselves, and getting it done right. Our goal is to arm you with the equipment and knowledge to take control of your water and save a fistful of money doing it. 

Put the Sun to Work on your land with the famous RPS 400 is trusted by  farmers and ranchers with moderate head and water requirements. Four solar panels can be mounted easily on a single pole, and at low head can still pump 2700 gallons a day, and over 400 gallons at 250 feet. And to give you more flexibility and peace of mind, batteries or a generator can be used to supplement as needed. The most efficient brushless permanent magnet motors mean no replacement of carbon brushes and years of smooth, reliable performance. Lifetime Rotor Warranty and the only field-serviceable pump available save you thousands over other options.

Happy customer

I have been using my RPS 400 for two months now. I couldn’t be more pleased with the ease of installation and operation of it. It’s a vast improvement over the windmill.

Easy to install

So far, I'm impressed with the system. Easy to install. I re-read the manual about 20 times to make sure I was reading it correctly because I expected it to be more difficult than it was. This is my first experience with any kind of well system. So far, I'm more than happy with the purchase.

I’m so grateful that my husband will never have to climb that tower again.

We’re pumping into a big tank that runs into a little tank. In the summer we pump out of the big tank up to a tank in another pasture about 100 yards away. In the winter, we’ll move the float to the small tank. He rigged a pipe on the side of the tank to protect the float inside.

I’m so grateful that my husband will never have to climb that tower again.

The fish/swimming pond

The pump exceeds the specs. Great system.
