Farm Solar Panel Calculator

Estimate solar for agricultural operations — barns, irrigation & more

✓ Free estimate, no signup required

Farms and agricultural operations are often excellent solar candidates. High electricity consumption (irrigation pumps, climate-controlled barns, grain drying, refrigeration), large flat roof areas on outbuildings, and substantial ground space make farms well-suited for both rooftop and ground-mount systems. Agricultural solar can dramatically cut operating costs and — through USDA REAP grants — access additional incentives beyond the 30% federal ITC.

Key Considerations for Farm & Agricultural Solar

  • ✓Ground-mount systems are common on farms — no roof space constraints
  • ✓USDA REAP (Rural Energy for America Program) grants cover 25–50% of eligible system costs
  • ✓Irrigation load profiles often align well with solar production (daytime pumping)
  • ✓Three-phase power may be required for large pump motors — check with your installer
  • ✓Agrivoltaics (dual land use for crops and solar) is an emerging option for row crop operations

Farm & Agricultural Solar Solar — Frequently Asked Questions

How much solar does a farm need?▾
It varies enormously by operation type. A small hobby farm with a barn and basic loads might need 10–20 kW. A mid-size operation with irrigation, refrigeration, and climate-controlled barns might need 50–200 kW. Large commercial farms can install 500 kW or more. Enter your actual monthly bill in the calculator above to get a baseline estimate, then consult a commercial installer.
What is the USDA REAP grant and how does it help farmers with solar?▾
The USDA Rural Energy for America Program (REAP) provides grants covering 25–50% of eligible renewable energy system costs for agricultural producers and rural small businesses. Combined with the 30% federal Investment Tax Credit, eligible farmers can receive 55–80% of solar system costs back in grants and tax credits. Applications are submitted quarterly through USDA Rural Development offices.
Are ground-mount solar systems better than rooftop for farms?▾
Often, yes. Ground-mount systems can be optimally angled (typically 30–35° in the US), are easier to maintain, can be expanded, and don't add structural load to aging barn roofs. They also allow future panel upgrades without roof penetrations. The tradeoff is land use and higher installation cost per watt ($0.20–$0.50/W premium over rooftop).
Can farm solar systems run irrigation pumps directly?▾
Yes — this is one of the best applications for agricultural solar. Solar production peaks align with peak irrigation demand on sunny days. Variable-frequency drives (VFDs) allow pump speed to match solar output. Direct-pump systems (no battery) are the simplest and most cost-effective approach for daytime irrigation needs.
Does solar make sense for a small family farm?▾
Often yes, especially with REAP grants and the 30% ITC. A small farm spending $400–$800/month on electricity could install a 20–40 kW system for $60,000–$120,000 before incentives. With 55%+ in grants and tax credits, net cost drops to $27,000–$54,000, with payback periods of 5–8 years — and 25+ years of near-free electricity after that.
