What we do
Four services, one accountable contractor
We read your utility bill first, then decide what to build. Sometimes the answer is not more panels — it is storage, or it is fixing a power factor penalty you did not know you were paying.
Battery Storage
Commercial Battery Storage Installation in the Southeast
Three-phase hybrid battery systems sized from your interval data, built to hold down demand charges and keep critical loads running when the grid does not.
Micro-Grids
Commercial Microgrid Installer for Sites That Cannot Go Dark
Islandable solar and battery micro-grids that separate the loads you cannot lose from the ones you can, and carry them through an outage without a fuel delivery.
Power Factor Correction
Power Factor Correction Services for Commercial Sites
The cheapest fix on most commercial power bills. Correcting a poor power factor removes the utility penalty and often pays back faster than solar, so it should usually be done first.
Our own product
BatteryCube® commercial battery energy storage
Our own branded outdoor battery cabinets, built around CATL cells. 55,000 lb of them are running at the Samsonite and TUMI site today.

The Westin Dawn Beach Resort & Spa
The largest hospitality system OneWorld Solar has built: 800 kW of rooftop solar on an operating beachfront resort in St. Maarten, engineered for island grid economics and Caribbean wind loads.
Who we build for
A chicken house and a showroom use power very differently
The right system follows the load, not the roof. These are the four sectors where we have built the most and know the economics best.
Over 4.8 MW installed on U.S. poultry houses
Solar Panels for Poultry Farms and Chicken Houses
Broiler and breeder houses have long metal roofs and a daytime fan load that lines up almost perfectly with the sun. We have installed over 4.8 MW on U.S. poultry farms, including a 450 kW 14-house broiler system.
1 MW+ installed across the Woody Folsom Automotive Group
Solar for Car Dealerships and Auto Groups
Dealerships burn power all day for showroom HVAC, lighting and service bays, then all night for lot lighting. We have built more than 1 MW across Woody Folsom Chevrolet, Ford and Chrysler Dodge.
800 kW at the Westin Dawn Beach Resort & Spa, St. Maarten
Solar for Hotels and Resorts in the Southeast and Caribbean
Hotels run 24/7 and guest comfort is not negotiable. We built 800 kW at the Westin Dawn Beach Resort & Spa in St. Maarten and work across Florida, Georgia and the Caribbean.
1.267 MW plus 55,000 lb of battery storage for Samsonite/TUMI
Solar for Manufacturing Facilities and Warehouses
A distribution center roof is usually the largest unused asset a manufacturer owns. We built 1.267 MW of rooftop solar and 55,000 lb of BatteryCube storage for Samsonite and TUMI in Vidalia, Georgia.
What the incentives do to the net cost
Three federal programs do most of the work on a commercial project. They stack, but the order matters, the terms change, and a credit is worth nothing to a business without tax liability. We prepare the documentation; your accountant makes the call.
- USDA REAP GrantGrants and guaranteed loans for rural businessesThe Rural Energy for America Program offers grants and guaranteed loans toward renewable energy systems for agricultural producers and rural small businesses. It is competitive, scored and awarded before you build.
- Federal Tax CreditA federal investment tax credit on eligible project costThe federal investment tax credit reduces tax owed rather than income taxed, which makes it far more valuable than a deduction — and worthless to an entity with no liability. Here is how the structure works.
- Section 179 & DepreciationAccelerated write-off of the solar assetSection 179 expensing, bonus depreciation and MACRS are three separate mechanisms that most business owners treat as one. The difference between them decides how much of a solar array you write off, and when.

What customers say after the crews leave
“The working system is producing more power than expected, with nearly no maintenance issues. The monthly power bill savings of $1,800.00 per month is nice also.”
Dal DurdenPresident, Swainsboro Supply CompanySwainsboro, GeorgiaRead the Swainsboro Supply Company case study “In years past we have seen our electric bills run over $2,000.00 in the summer months. This past month we received a big flock of birds and our electric bill was only $750.00. Solar works. We received our USDA Grant, 30% tax credit and section 179 depreciation.”

Data center rate class in North Carolina: what the Attorney General is asking for
On September 14 North Carolina's Attorney General asked the Utilities Commission to create a dedicated rate class for Duke Energy's data center customers, publish Duke's template contracts, move load forecasts to every 90 days and pause new gas plants until the forecasts are re-read. Duke says 80% of its new demand comes from data centers and large users.

Final solar duties on India, Indonesia and Laos: what changes in a fall 2026 quote
On September 11 the Commerce Department made its solar duties on India, Indonesia and Laos final: dumping margins of 123.04%, 94.36% and 65.43%, with subsidy rates on top that take combined duties past 200% for every origin. The ITC votes October 14. What that does to a commercial quote this fall, and how to fix the supply before then.

Common questions
About OneWorld Solar
What does a commercial solar company do that a residential installer does not?
Commercial work turns on three things residential rarely touches: three-phase power, demand charges, and a formal utility interconnection study. A commercial project needs stamped engineering, an interconnection application and switchgear coordination before anyone climbs on a roof. OneWorld Solar works only on commercial and agricultural systems, typically from 100 kW to just over 1 MW.
Which states does OneWorld Solar work in?
We are headquartered at 609 Church Street in Vidalia, Georgia and build across Georgia, Florida, South Carolina and North Carolina, plus the Caribbean, including St. Maarten and the U.S. Virgin Islands. Our VP of Engineering is a Professional Engineer licensed in South Carolina, North Carolina, Florida, Georgia, Virginia and Texas.
How long has OneWorld Solar been in business?
Since 2001, which makes it the oldest solar company in the Southeast. Doug Baird acquired the company in October 2017 and rebuilt it around large commercial and agricultural customers. Revenue has grown from zero at acquisition to $7.8 million in 2024, across more than 300 customers and over 7.8 MW installed.
What is the first step in getting a commercial solar quote?
Send us twelve consecutive months of utility bills. Not just the totals, the full bills, because the rate schedule, the demand charges and any power factor penalty are all on them and none of those show up in a monthly figure. From there we walk the site and come back with a system size, an installed cost, applicable incentives and a payback range at no charge.
