    ⭐⭐⭐⭐⭐ Reviews - America's #1 Most Popular!

    Customers send in hundreds of notes each season expressing their newfound love for solar pumping.  Our job is not done until you are pumping water, and our support of you as you do it is unconditional. We love solar pumping and you will too.


    All your videos are spot on. If people took the time to watch them before installing they’d never have to call you. I loved the user manual. The way my wife follows her recipe for cooking… that’s how I followed your user manual. I loved it. Every second of it. I’ve never had customer service like this.

    - David, TX


    RPS is now one of my very favorite companies.With the help of Daniel, I purchased a 6000watt Water Secure System. It was a great project to install and brought me back to using some skills that I haven’t used in years. It worked perfectly as soon as I turned it on.

    - Susan, OK


    We’re getting close to what, roughly five years but it’s working fine still.It’s been the best investment we’ve ever done, sir.Seriously. Oh yeah, the best thing we’ve done. We don’t have to run a generator, we’ve got plenty water, it’s always full, it always works and we can almost turn back on it.

    Solar Pumping FAQ

    How can I be sure I have the correct size solar pump?
    The online Pump Sizing Wizard starts with over 100 RPS Solar Pump models and using the variables you enter about your well depth, latitude and your water needs to size your system correctly the first time. Or if you prefer talking with a friendly specialist, give us a call at 888-637-4493

    How long does it take to install?
    Most people find it can be easily done over a weekend and our record is a customer who installed their RPS200 system in 1 hour and 7 minutes! It's as easy as mounting your solar panels, dropping the pump down the well, and flipping the switch!

    What resources are there to help me install?
    Countless features and included parts and pieces make the install of an RPS pump easier than ever - for first timers and old timers alike. Our 64 page all-color user manual outlines the entire process, YouTube videos demonstrate it visually and the “DIY Success Center” (100+ articles and videos FREE access with purchase!) is available anytime, and our engineers are ready to help over email, phone or text.

    How is shipping cost calculated?
    Shipping is currently FREE with the current sale but the sale expires at the end of the month.

    How does it ship? Timeframe to expect?
    We make every attempt to ship the same day the order is received. Sometimes, this is not possible due to popularity, and the items will ship the following day or days. Many of our systems include bulky solar panels. Shipping times and delivery dates are estimates only as these services don’t offer guarantees, but often between 2 and 5 days transit for boxed systems depending on your area in the US.

    In a hurry? Most systems can be expedited 2nd Day Air, we just need to know in advance and we just ask you cover the difference in cost between Ground shipping and 2nd Day Air. Freight deliveries like WaterSecures and larger Pro Series with Large Panels we use pallets and FedEx Freight. Shipping times are a little harder to estimate here. Packing and palletizing may take 1-2 days based on the season. You will be sent a tracking number once your order is scanned and in transit! ** RPS Ship-Insured™ guarantees you get what you ordered in working condition and combines with the 100% Water Assurance Guarantee to add additional peace of mind that your investment will result in water pumping!

    Can I supplement the sun with power from batteries or AC/Generator?
    Absolutely. But neither is necessary. Batteries allow for the storage of solar power during the day to be used at night or on cloudy days. AC/Generator converters mimic the power the sun might provide on a perfectly sunny day with AC whenever you have it. There is also an AutoSwitcher box that automatically switches between AC and Solar, weather depending.

    How much area do I need for the solar panels? 
    Rough dimensions of solar panels and array sizes can be found below.

    How big are the Solar Panels? How many?
    We size with versatile, rugged and easy-to-install 100w panels. Take the kit name (RPS 200) and divide by 100 watts for the number of panels in the kit. RPS200 = 2 100w Solar Panels. RPS800V = 8x 100w Solar Panels. Once over 1.5HP Pro Kits, large 300+ watt panels are used. Small and Large panels still have roughly the same total dimensions and surface area per watt. Smaller panels are just easier to work with, transport, and create building blocks that are easier to upgrade in the future.

    What is the best way to mount the solar panels?
    Mounting is easy. Panels are rigid aluminum framed so can be fastened down in a number of ways. Tilting south and adjusting to your latitude is most important vs material or construction of mounting. There are our adjustable pre-made options, and hundreds of photos of do-it-yourself mounting here.

    Wait, so no batteries needed?!

    Some customers just can’t believe that these pumps will work on solar power alone. They are even more delighted when they get water - and usually more than they think with only the sun! It feels like magic! Film a video of a loved one when you first turn the system on - the expressions of awe are priceless! 

    RPS systems run incredibly efficiently using solar power alone. No batteries needed. While it does make sense for some customers to add a battery bank (especially with low GPM wells and for household water pressure), whenever possible, our engineers do recommend pumping more water into a storage tank for overnight use. We have more info on batteries here. Most customers start without batteries regardless, as they are easy to add in the future if desired.

    Can I add more Gallons Per Day in the future with more panels?
    Yes! Systems are generally very modular and you can see what “Water Upgrade Kit” (solar panels and wiring) is compatible with your system and can easily be added later. Add a compatible battery bank with more solar panels to unlock nighttime operation! 

    I don’t need that much GPM, can I turn the rate of pumping down?
    Lower production wells might produce less than a gallon a minute and one of the great features of RPS pumps is that the controller’s speed dial allows you to reduce the motor speed, pumping at a slower rate to match the replenishment rate of the well or water source. 

    What does Water Assurance Guarantee mean?
    We offer a money back guarantee that our pump systems will provide you water off of solar power when sized by one of our engineers to your well, desired setup and final total dynamic pumping head. We do require static water levels, drawdown and pressure requirements are accurately estimated during the sizing process, that installation follows the instructions of the RPS User Manual, and that you give RPS engineers a chance to troubleshoot any issues.

    Lifetime Rotor Replacement Guarantee
    Our brushless motors are designed to last for tens of years without maintenance. These motors (at the bottom of the pump) turn a stainless steel helical rotor inside a rubber-lined stator. Helical rotors are incredible for utilizing low power, so it makes them perfect for solar use. But these rotors are inherently the weakest point of the entire system, just like all helical pumps, especially in sand or iron-rich soil. With RPS you won’t ever have to mail your pump off to get a factory rebuild. Replace the rotor yourself on site and save time and money. No need to cut wires either, just open up the upper pump end and swap in a new rotor and your pump will operate as it did the day you installed it. Our Replacement Guarantee Policy means that we will replace these rotors whenever they wear for the lifetime of your pump’s motor. The rest of the system is convered under the 2 Year Comprehensive Warranty and Lifetime Phone Support. 

    Why choose RPS?
    We're 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. 

    What’s the submersion limit on the 2" and 3" submersible pumps?
    The submersion limit is also different than the “total head ability” of each pump. Most people place their solar pump 20-50 feet below the water surface, as compared to a typical AC pump which installs 10 feet off the bottom of the well, but anywhere within 0 and 129 feet is acceptable. RPS specialists will help size a solar pump that best matches your well's production rate.

    Still not sure which size solar pump?
    We have built the industry’s best Pump Sizing Guide which is online for convenience. Once you add details about your well and water use, it will recommend a pump. If you’d like, we’ll also have an engineer call you and make sure we have the right size selected.  888-637-4493

    An elegant solution for a simple, but potentially serious, problem; loss of grid power

    I first came across RPS Solar's Water Secure system a few years ago (2018?). I loved the concept of having solar back up for my well, but it wasn't in our budget and we didn't have an enclosure over our well.

    Fast forward a few years and we now have a well house with a 6K Water Secure system and their 8-panel PV mount. The system showed up on a pallet, as stated. It came on a big truck, so make sure a tractor trailer can navigate your property. The truck had a lift gate and lowered the pallet into my pick up truck. It is heavy as a pallet, but the individual components are not too bad. Only the inverter/charge controller required to people to comfortably and safely move.

    Speaking of the inverter/charge controller, it will come in it's own well-built crate. It's very well packaged and protected. Everything else is in cardboard boxes. You should inspect everything as soon as possible, even if there is no outward appearance of damage.

    Installation of the system was pretty straight forward and not too difficult. If you're not comfortable doing electrical work, hire a professional to avoid damage and/or injury. Also, when running the PV cables from the panels to the switch block in conduit, ensure you have one male and one female end before you run those cables; they are shipped m/m f/f.

    The only 'issues' I had were: 1) They don't sell the 4.5" steel post needed for the PV mounts. However, I sourced it from an online retailer. 2) You need a ground rod, which isn't mentioned online. Not a big deal, but you will need one. 3) 1 PV panel was damaged in shipment. 4) There were some wording conflicts within the manual.

    Customer service is amazing! Before I received the shipment, they informed me of a potential error with my PV mount and the solution if I encountered said error. Also, I emailed photos of the damaged PV panel to customer service and they immediately shipped a replacement panel. I also spoke to them about the wording of the manual and they were both profession and receptive. They cleared up my confusion and stated they planned to fix the error in the upcoming updated manual.

    After my experience, I would absolutely do it again. I don't know if there is another company doing this sort of work out there, but they would be extremely hard pressed to out perform RPS.

    Pleasurable DIY experience

    My deep well power backup system is up and running. Currently, the panels are not at optimum sun angle but are actually providing adequate power to the system. I want to thank everyone at RPS for their assistance and friendly customer service. This has been a most pleasurable DIY experience, and I will be sure to highly recommend RPS for anyone's power backup requirements.
