How to size and select a solar water pumping system
In short, all the information we need to size a solar pump system at Grundfos is the project''s location, the flow per day, the static lift and the dynamic water level.

Discover the capabilities and limits of solar pumps in this detailed guide, exploring how high they can push water and what factors influence their performance.
The Vecharged Rule of Thumb: For every 100 watts of solar panel, you can typically expect to pump around 1,000 gallons of water per day to a moderate height (e.g., 20-30 feet).
The height a solar pump can push water, known as "head," varies significantly by type. A solar screw pump can achieve a high head of over 150 meters, while centrifugal impeller pumps are designed for medium heads,
By inputting this information, our calculator will help determine the appropriate pump size to ensure optimal performance. Whether you''re considering a solar water pump for agriculture, irrigation, or any other
Please note that the listed depths are the depth limits for each configuration, and if the pumping results are at the low end of your requirements, look to increase your solar panel configuration or visit the next rated pump
Nowadays, with a modern solar pump, we''re able to pump up to around 1400 feet of pumping head and that 1400 feet is comparable to even some of the most powerful AC pumps.
This kind of pump has a high pressure switch that shuts the pump off when the pressure the pump sees goes above 45 psi. So, if the pump is seeing quite a bit of resistance, it will cycle off
Daily energy use (Wh) → how much power the pump consumes in 24 hours. Instead of guessing or relying on trial-and-error, this calculator uses physics formulas to give accurate numbers based on
**A solar-powered water pump can raise water up to 200–300 meters, depending on pump design, total dynamic head (TDH), and solar power capacity. Proper sizing ensures efficiency and long-term
