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.
