Solar vs. utility and generator irrigation
| Evaluation Factor | Dankoff Solar System | Grid extension / Diesel engine |
|---|---|---|
| Operating cost | $0 / month fuel or electric bills | Rising diesel prices or monthly utility demand fees |
| Summer alignment | Pumps maximum volume during hot dry spells | Fixed utility tiers / high generator run hours |
| Service life | 15-20 years with regular maintenance | Frequent engine rebuilds and fuel hauling |
| Automation | Auto starts with sunlight, shuts off on tank full | Manual generator pull starts and monitoring |
Data verified from Dankoff Solar sizing manuals and field application studies.

Common Questions & Technical Answers
Direct engineering answers to the sizing, installation, and field reliability questions we receive daily from ranchers and solar installers.
Have an unlisted question or complex site?
Our engineers in Elk City, OK calculate total dynamic head and friction loss for your exact setup.
+1 505-471-346901Can solar pumps run pressurized drip irrigation systems?
Yes. Positive-displacement pumps like the SolarForce and SolaRam deliver the steady high pressure (40 to 100+ PSI) required to push through drip line filters and pressure-compensating emitters.
02How many gallons per minute can I pump with solar?
Depending on your total dynamic head and solar array size, Dankoff pumps range from 1 GPM for deep lift up to 70+ GPM for high-volume surface irrigation.
03What happens on overcast days?
Solar-direct pumps produce water proportionally to solar irradiance. Sizing your system with 20-30% solar array oversizing or incorporating an elevated storage pond ensures consistent irrigation yield.
