Solar Pump Brand Comparison

We often get asked how RPS Solar Pumps compares to Grundfos and WH solar pumps. While our engineers are happy to go into solar pump comparison in greater detail, here are some of the common responses – and the things that have differentiated RPS on the path to the #1 Solar Pump kit in America. Be sure to read all the solar pump reviews you can find. With most of our business coming from the referrals of happy customers, we are proud with the trust RPS has earned

For deeper wells or applications up to 300 feet of total head, the RPS 800 remains the best customer choice. Use it with a pressure tank and batteries, directly into drip lines or to a far away storage tank. Even float in a pond or river! Eight easy-to-mount solar panels offer powerful performance at an amazing price – up to 3200 gallons a day, and over 1,400 gallons at 300ft. 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 field-serviceable pump available save you thousands over other options.  Spec Sheet.

Our Most Popular Solar Pump: RPS 400

The famous RPS 400 is trusted by  farmers and ranchers with moderate head and water requirements. We sell the RPS 400 every. single. day.  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. Spec Sheet.

Most Affordable Solar Pump: RPS 200

Also our smallest system, the RPS 200 runs around $1700, you may be able to grab it for lower if you catch a seasonal sale! Great for those who want to start small with the possibility of expanding to four panels in the future( to create an RPS 400). Two solar panels in a 24V configuration offer an attractive blend of performance and price giving you up to 1800 gallons a day, and over 500 gallons at 150ft. 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. Spec Sheet.

Best Solar Pump for Off Grid Living: Tankless Pressure Pump

With the RPS Tankless Pressure™ System you’ll get smooth continuous steady reliable water pressure without the need for AC power or the utility grid. The solar charged battery bank powers a centrifugal booster pump that varies its speed and power based on your demand for water at the exact pressure you select from 20 to 45psi. Need reliable drip irrigation? Set system to 20 or 30 psi. Need household water pressure or sprinklers? Set system to 45psi. Flow rates from 5 to 25 GPM are supported. 15’ suction from a pond or shallow well with foot valve. When possible, reducing distance between foot valve and pump helps in priming. 1-1/4″, 1-1/2″ or even 2″ for longer runs helps prevent frictional loss if over 50 feet. Pump has 1.25″ FNPT Inlet, 1″ FNPT outlet. Online spec sheet.

Best Solar Pump For Deep Wells: Pro2000D

The Pro Series D pumps are designed for high head, lower volume applications. All the way up to 1,000 feet of total head! The Pro2000D handles up to 950 feet of head for $5999. If you need a bit more wiggle room, opt for the Pro3000D.  Theses pumps are  recommend using a local installer who has the equipment to lower the pump/cable/pipe safely.

Our Pro Series D systems use hearty 3-Phase Motors and 3.9″ Pump Ends. Our controllers are the best in the world and allow customization and optimization based on sun and season.

Best Solar Pump For Narrow Wells: RPS 400N

The newly redesigned Narrow pump is a miraculous 2.01″ in diameter and the first of it’s kind. Yes, it can sneak in next to an existing pump/drop-pipe in a 6″ well casing to act as a backup redundant pump, or if a pump is stuck down in the well. It fits 2.5″ and 3″ casings that are so common in old windmills. Finally a solution for windmill wells that could never take a submersible pump before!!

Like our 3″ pumps, the RPS 400N features a helical rotor. These pumps are designed to operate on solar power alone and feature a brushless DC motor to keep temperature down and efficiency up in a tight well casing. 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.

Best Solar Pump For Sprinklers: Pro Irrigation Surface Pump

The Pro Irrigation Pumps are high volume, mid-head, non-submersible applications where suction still may be necessary. Made specifically for irrigation, great for sprinklers up to 45 psi, but can also supply drip lines without over pressurizing.  Self priming suction up to 25′ but the less priming, the better GPM production at lower head. The systems use best-of-the-best USA 3-Phase Pumps.  Pump from sun up to sun down or program an irrigation timer for a custom watering schedule. Cast iron construction sealed with corrosion resistant Electrocoat paint.

Best Solar Pump For Dewatering: Pro Dewatering Pump

The Pro Dewatering Pumps are super high volume, low head applications where water may contain solids (max 2” solids diameter). Capable of running dry and performing 24/7 operation without damage. This 3-Phase “grinder” pump is ideal for dirty field tiles or large irrigation projects. The systems use best-of-the-best USA 3-Phase GOULDS Pumps. Corrosion resistant cast iron and stainless steel construction. Pro Controllers allow customization and  optimization based on sun and season. Option to use 220V AC from the grid or generator serves as a backup using the versatile RPS  Pro Controller, designed to automatically switch between Solar and 220V.

Quickly pump water in an agricultural setting with our highest volume offering (up to 475 GPM using the ProW 5 HP XL). Especially helpful when pumping from an exposed area like a canal, spring or pond that might include sticks or natural debris, as the dewatering pump will chew right through them. Other customer projects include filling ponds from a creek, pumping into high volume storage and draining flooded property. Option to utilize a float switch to shut off the pump if the water level drops.

Best Solar Pump For High Volume Wells: Lakemaker XL 5 HP

Yes, you can run a 5 HP pump on solar power! The Lakemaker XL 5 HP line uses a special high voltage Pro Controller, twenty 310W panels and either 4′” or 6″ diameter pump ends. These systems are used in gold mines, marina aeration, industrial irrigation and so many more unique applications.
