What we do
Commercial Solar EPC
One contract, one accountable party: engineering, procurement, construction, interconnection and commissioning for commercial solar arrays from 100 kW to multi-megawatt.
Battery Storage
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
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
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
Our own branded outdoor battery cabinets, built around CATL cells. 55,000 lb of them are running at the Samsonite and TUMI site today.
Proof, not promises

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
Over 4.8 MW installed on U.S. poultry 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
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
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
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.
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.
Client results
“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.”
“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.”
“Your performance throughout the project was professional and you treated the owner, architect, and contractors with utmost respect.”
Insights

Battery Storage
A battery only pays for itself if your utility bill is paying for something a battery can change. Here is how to read your own tariff for demand charges, ratchets and time-of-use pricing before anyone quotes you a system.

Costs
An honest breakdown of commercial solar cost per kW in Georgia: why price per watt falls with system size, what the line items actually are, which four variables swing a quote, and how to compare two proposals that look different.

Industry
Three installed poultry systems — 210 kW on six breeder houses, 450 kW on fourteen broiler houses, 410 kW on sixteen — and what the differences between them tell you about sizing, cost and payback on your own farm.

Common questions
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.
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.
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.
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.
Send us twelve months of utility bills and we will come back with a system size, a cost, the incentives you qualify for and a payback range — at no charge.
