Buying Guide: What to Look For in an RPS Solar Well Pump
Pump Type: Screw vs. Centrifugal
Screw pumps (also called helical rotor pumps) are excellent for deep wells and high heads. They move water upward using a rotating screw inside a rubber stator, which also handles sand and debris better than centrifugal designs. The DIFFULPumps models in this list use this technology, offering heads up to 495 feet. Centrifugal pumps, like the ECO-WORTHY units, are simpler and more affordable for shallow wells under 100 feet. Match the type to your well depth and water quality.
Power Source: DC vs. AC
Most solar well pumps run on DC power (12V, 24V, or 48V) so they can connect directly to solar panels or batteries. This makes them truly off-grid. Some pumps, like the ZHIKMIAO models, are AC-powered (110-130V) and need an inverter or generator, which adds complexity. For a pure solar setup, choose a DC pump with an MPPT controller that optimizes energy harvest. If you already have AC power at the wellhead, an AC pump may be more efficient. Our complete well pump guide can help you decide.
Flow Rate and Head Requirements
Flow rate (gallons per minute) and head (vertical lift) determine if a pump can meet your daily water demand. A family of four typically needs 10-15 GPM for household use, while irrigation may require more. For deep wells over 200 feet, look for a pump with a high head rating, like the DIFFULPumps 495-foot model. For shallow wells under 100 feet, the ECO-WORTHY 12V pump with 100-foot lift is a budget-friendly choice. Always check both specs together: a pump that delivers 8.8 GPM at 495 feet is far more capable than one that only achieves that flow at zero head.
Build Quality and Warranty
Submersible pumps live in harsh conditions: constant moisture, temperature swings, and sometimes abrasive water. Stainless steel components, NSK bearings, and high-temperature copper wire, as seen in the DIFFULPumps, extend service life. A good warranty (2 years or more) gives confidence. The ECO-WORTHY pumps come with customer support for solar setup, which is a plus for first-time buyers. For more tips on choosing the right kit, read our well pump kit buying guide.

Frequently Asked Questions
Can a solar well pump work at night?
Yes, if you include a battery bank. During the day, solar panels charge the batteries, and the pump can draw from them at night. Some pumps also come with a controller that switches to battery power automatically when sunlight fades. Without batteries, the pump only runs when the sun shines.
How deep can a solar well pump go?
It depends on the pump model. Screw pumps in this list can lift water from up to 495 feet, while smaller DC centrifugal pumps typically handle 100 to 230 feet. Always check the maximum head rating and ensure it exceeds your well depth by at least 10% to account for friction losses.
Do I need a controller for a solar well pump?
Most solar pumps come with a controller or require one. The controller regulates power from the solar panels, protects the pump from dry run and overvoltage, and often includes an MPPT function to maximize energy harvest. The DIFFULPumps kits include a controller; the ECO-WORTHY pumps can be used with a separate charge controller or directly with a battery.
What size solar panel do I need for a well pump?
Panel size depends on the pump’s power consumption. A small 12V pump drawing 96W, like the ECO-WORTHY, works well with a 200W panel. Larger pumps (up to 1.5 HP) may require 1000W or more of solar array. Check the pump’s wattage and add 20-30% for cloudy days. For a full system design, consult our well pump kit buying guide.
