Two poultry houses with rooftop solar panels and a small ground-mounted array beside pine trees in rural Georgia.

Solar for poultry farms in Georgia works best when the array is sized to the farm's daytime fan and feed load, not to its roof area, because Georgia Power and the EMCs we checked credit exported solar at well below the retail price. Under the illustrative assumptions below, a 100 kW system on a broiler farm using about 150,000 kWh a year pays back in roughly 16 to 27 years on cash alone, and faster only if a federal credit or other support genuinely applies to your project.

Georgia is the nation's leading broiler state, and poultry operations are present in 115 of its 159 counties, according to the University of Georgia. That makes poultry houses one of the most common commercial-scale solar questions in rural Georgia, from the farms around Gainesville to those in south Georgia served by Georgia Power or an electric membership corporation (EMC). This guide explains what drives the numbers so you can test any proposal you receive.

Where a Georgia poultry farm's electricity goes

In a tunnel-ventilated broiler house, electricity runs fans, feed lines, lighting, well pumps and controls, while propane or natural gas usually supplies the heat. A University of Arkansas study of a modern broiler house found ventilation fans accounted for 88% of electricity demand and drove the farm's peak demand, with summer demand about four times higher than winter. Georgia houses are built and run in a similar way, so expect the same pattern: a big summer daytime load that lines up well with solar output, and a much smaller winter load.

Two consequences follow:

Summer fits solar. Fans run hardest on hot, sunny afternoons, so much of the summer output is used on site.
Spring, fall and cleanout periods do not. Between flocks and in mild months the load drops while panels keep producing, and that surplus is exported at a low rate.

A UGA Department of Poultry Science review of Georgia poultry solar systems reported designs producing about 60–65% of a farm's annual usage, with about 15–18% of the array's output sent back to the grid. Pull 12 months of interval or monthly bills for every meter on the farm before talking to anyone about system size.

Georgia Power vs EMC buy-back rules for farm solar

Who serves the farm matters more than almost any equipment choice. Many Georgia poultry farms are on EMC lines rather than Georgia Power, and the rules differ. These are the rules as published on each utility's own pages today; check your own utility before relying on them.

Item	Georgia Power (RNR program)	Example EMC: Walton EMC
Size limit for the buy-back program	Commercial systems up to 250 kW AC; systems from 100–250 kW AC may not exceed 125% of the prior year's metered peak demand	Up to 100 kW for commercial applications
Credit for exported kWh	Annual solar avoided energy cost (3.3153¢/kWh listed for 2025, reset each January) plus a 4¢/kWh adder approved in the 2022 rate case	2.6¢/kWh for 1/1/2026–12/31/2026
Program cap	0.2% of prior-year peak demand, first come, first served	0.5% of prior-year peak demand, first come, first served
Fees noted	$200 interconnection fee up to 250 kW AC; larger systems go on Energy Offset Only with witness test and impact study fees	Customer pays incremental metering cost, currently $800, plus interconnection costs

Georgia's Cogeneration and Distributed Generation Act sets the statewide framework, but each EMC and city utility publishes its own rates and interconnection steps. If your farm is served by a different EMC, find its "solar" or "distributed generation" page and its interconnection agreement before any design work starts.

Roofs, ground mounts and site checks

Long, low poultry-house roofs look ideal, but UGA cautions that roof-mounting needs a newer roof with durable materials that can carry the panel load. Before choosing roof or ground:

Roof age and structure. If the metal roof or trusses will need work within the array's life, removing and reinstalling panels later adds cost. A licensed structural engineer should confirm capacity, including wind uplift.
Orientation. Many houses run east–west to suit ventilation, which leaves a roof face pointing south. A house running north–south gives two east- and west-facing slopes that produce less per panel.
Dust and ammonia. Exhaust from tunnel fans carries dust and moisture. Keep arrays away from the fan end, and plan for cleaning and corrosion-resistant hardware.
Ground mounts. UGA notes many Georgia farms use spare land for ground arrays, which avoids roof risk but needs land, fencing, setbacks and a trench to the service. Check county zoning and any biosecurity rules from your integrator.
Service and meter layout. Farms often have several meters. Solar can only offset the meter it is connected to, so map which meter carries the fan load.

Illustrative payback for a Georgia broiler farm

Illustrative assumptions, not a quote or project data. Annual farm use: 150,000 kWh (the scale used in a University of Arkansas extension broiler-farm example). Array: 100 kW DC, south-facing at 20° tilt, 14% losses. Production: about 1,412 kWh per kW per year, from NREL PVWatts v8 monthly results for Atlanta as published by a third-party site; we could not run PVWatts directly today, and south Georgia sites typically produce somewhat more. Export share: 17%, within the 15–18% UGA reported. Installed cost: $3.00 per watt, the average Georgia Power's commercial FAQ cites ($300,000). The table covers energy savings only: no O&M, inverter replacement, degradation, financing, tax effects or demand-charge savings.

Result: about 141,250 kWh a year, of which about 117,238 kWh is used on the farm (78% of its load) and 24,012 kWh is exported.

Value of each self-used kWh	Export credit	Year-1 savings	Simple payback, cash	Simple payback if a 30% credit applied
9¢	7.3153¢ (Georgia Power, 2025 figures)	$12,308	24.4 yrs	17.1 yrs
9¢	2.6¢ (Walton EMC, 2026)	$11,176	26.8 yrs	18.8 yrs
11.4¢	7.3153¢	$15,122	19.8 yrs	13.9 yrs
11.4¢	2.6¢	$13,989	21.4 yrs	15.0 yrs
14¢	7.3153¢	$18,170	16.5 yrs	11.6 yrs
14¢	2.6¢	$17,038	17.6 yrs	12.3 yrs

11.4¢ is EIA's 2024 Georgia average retail price across all sectors; your farm's real figure is the energy charge you avoid, which may be lower if demand and fixed charges make up much of the bill. Three lessons stand out:

The retail rate you avoid moves payback more than the export credit. Going from 9¢ to 14¢ cuts payback by about eight years; the export-credit gap moves it by one to two.
Demand charges may not fall. Fan demand can peak in the late afternoon or on cloudy hot days, so treat any demand savings as a bonus to be shown with interval data.
Oversizing hurts. Every kWh above what the farm uses at that moment earns only the export credit.

Federal tax credits and USDA REAP in 2026

Federal credit. Under the 2025 budget law, IRS guidance (Notice 2025-42) says the clean electricity investment credit (Section 48E) ends for solar facilities placed in service after December 31, 2027, unless construction began by July 4, 2026 under the IRS beginning-of-construction rules. A farm project starting now would generally need to be placed in service by the end of 2027 to qualify, and other conditions apply. Whether you can use a credit also depends on your tax liability. Confirm with a tax professional before counting it.

USDA REAP. UGA extension materials note that many Georgia poultry growers used Rural Energy for America Program grants in the past. As of today USDA's program page says the agency "is not accepting REAP grant applications at this time," while guaranteed loan applications may still be submitted. Contact the Georgia USDA Rural Development energy coordinator for current status rather than assuming a grant.

Ownership options for Georgia farm solar

Cash. Simplest, and you keep any savings and credits you qualify for, but it ties up capital the farm may need for house upgrades.
Loan. REAP-guaranteed loans remain listed by USDA; farm credit lenders and banks also finance equipment. Compare the loan payment with year-1 savings from your own bills.
Lease or power purchase agreement. Georgia's Solar Power Free-Market Financing Act of 2015 allows third-party financing of on-site solar, including agreements where payments are based on the system's output. The utility can still require its safety and interconnection standards. Have an attorney review term length, escalators, roof access and what happens if you sell the farm or change integrators.

Whatever the structure, ask for the production estimate, the self-consumption assumption and the rate assumption in writing, and check them against your bills.

Assumptions and limits

All figures above are illustrative. Production uses Atlanta PVWatts data reported by a secondary source, not a site-specific run. Farm load shape, flock schedules, roof condition and rates vary widely. Utility rules change: Georgia Power resets its avoided cost each January, and EMCs set their own rates. This is not financial, legal, tax, structural or electrical advice. Any project needs utility approval, local permits and a licensed contractor, and incentives should be confirmed with a tax professional.
