Commercial solar in Savannah, GA
Why the numbers favour business · as of August 2026
Georgia Power credits exported power at about 7.22¢ per kWh (a 3.2188¢ avoided-cost rate plus a 4¢ adder) against about 13¢ per kWh rate, so the value sits in consuming your own production. A Savannah business that runs through daylight hours self-consumes most of what it generates, which is exactly what the current RNR Instantaneous Netting structure rewards. That is a structural advantage over a typical home.
Local commercial reality
The commercial picture in Savannah
Savannah commercial work splits into two projects with little in common. Downtown frontages sit under the same historic review as the houses, so roof-mounted equipment visible from the public right of way becomes a Certificate of Appropriateness question before it is an engineering one, and older masonry buildings need a structural assessment before anyone discusses array size. Out toward the port and West Chatham the stock is modern low-slope membrane, where the roof is straightforward and the electrical service is the constraint.
The programme rules differ from residential in a way that matters. Georgia Power’s renewable programme takes commercial projects up to 250 kW AC with an interconnection fee, and larger projects follow a different route entirely. That threshold, rather than roof area, is often what decides the shape of a commercial design here.
Load profile decides the rest. With exports at roughly 7.22 cents against about 13 retail, a building that consumes its own production converts it at nearly double the value of one that exports. So we read interval data rather than assuming a nine-to-five profile: a restaurant peaking at seven in the evening and a warehouse peaking at noon are different economic cases on identical roofs.
Written for Savannah specifically. Your own roof, bill and meter still decide the answer, which is what the free assessment settles.
Why now
The 2026 rate change hurt homeowners and helped businesses
When Georgia Power closed one-for-one net metering to new systems at the end of 2025, it reduced the value of exporting surplus power. For a home that generates at midday and uses power at night, that was a real setback.
A commercial building has the opposite load shape. Offices, warehouses, retail floors and refrigeration draw hardest during exactly the hours a rooftop array produces hardest. Most of what you generate never touches the grid, so it offsets electricity at about 13¢ per kWh rather than earning about 7.22¢ per kWh (a 3.2188¢ avoided-cost rate plus a 4¢ adder).
Put plainly: the rate change that made residential solar harder to justify in Savannah left commercial economics broadly intact, and in relative terms improved them. That is worth knowing if you looked at solar for your building a few years ago and set it aside.
Summer cooling load reinforces this. Your peak demand and peak solar production land in the same months and largely the same hours. Long hot summers with cooling load peaking in the same hours the roof produces hardest, and a genuine hurricane exposure. Storm outages here are a real planning input rather than a sales line.
The same rate detail from the homeowner's side is on Savannah solar incentives.
How we scope a building
Engineering first, sales second
- 01
Load profile and bill analysis
We read your actual interval data and tariff, not a square-footage estimate. For commercial accounts the shape of your demand matters as much as the total, and it determines whether solar is a strong or a marginal fit.
- 02
Roof, structure and electrical review
Low-slope membrane, standing-seam metal or ballasted, plus service capacity and switchgear. Coastal. Salt air and hurricane wind loading both apply, so attachment spacing, fastener specification and roof-penetration detailing are more demanding here than inland, and the correct hardware costs more than the catalogue default. This is the same engineering we do in Charleston, and every penetration is backed by our lifetime roof-penetration warranty.
- 03
Permits and interconnection
Building and electrical permits with plan review, structural sign-off, and Georgia Power interconnection. We manage the sequence and tell you what is genuinely outside our control.
- 04
Install, commission, monitor
Sequenced around your operations. We commission the system, hand over monitoring, document everything your accountant will need, and stay reachable afterwards.
Commercial systems carry our lifetime full-system and roof-penetration warranty alongside manufacturer coverage, so one contractor stands behind the roof and the array.
Building types
What we install on in Savannah
Offices and retail
Daytime-dominant load, strong self-consumption. Often the cleanest business case in the area.
Warehouse and light industrial
Large low-slope roofs with real capacity. Structural review and ballast strategy drive the design.
Multifamily and hospitality
Common-area load and metering structure decide what is worth doing. We work through the metering first.
Savannah specifics
What commercial work involves here
The constraints that actually shape a Savannah commercial design.
- 01
Coastal wind loading
Coastal. Salt air and hurricane wind loading both apply, so attachment spacing, fastener specification and roof-penetration detailing are more demanding here than inland, and the correct hardware costs more than the catalogue default. This is the same engineering we do in Charleston, and every penetration is backed by our lifetime roof-penetration warranty. On a commercial roof, attachment and ballast engineering is a substantive design step.
- 02
Plan review is certain
Systems around 10 kW and up get standard plan review, which covers effectively all commercial work. Budget time for it.
- 03
Interconnection timing
Georgia Power approval precedes energising, and the queue rather than the install usually sets your date.
- 04
Architectural review
Savannah has two different historic review bodies and which one you face depends on your address. The Historic District Board of Review handles the Downtown Historic Overlay District; the Historic Preservation Commission handles the Victorian, Streetcar and Cuyler-Brownville districts. Any exterior change visible from the public right of way, lanes included, needs a Certificate of Appropriateness, and rooftop solar downtown is genuinely petitioned rather than waved through. A Certificate of Appropriateness is not a building permit, and a project inside the districts needs both.
- 05
Metering and tenancy
Who is billed for what determines whether the project works at all. We resolve this before design, not after.
- 06
Roof age and warranty
A commercial membrane near end of life changes the sequence. One contractor behind both the roof and the array avoids the finger-pointing later.
Tax
Where we stop and your CPA starts
Commercial solar tax treatment is genuinely different from residential. Federal commercial provisions and depreciation may apply where the expired residential credit does not, and the structuring can materially change your return.
We are not going to model that for you. Installers who present themselves as tax advisers do their clients harm, and the numbers depend on your entity, your liability and your depreciation position, none of which we can see.
What we do instead: scope and build the system properly, document it to the standard your accountant needs, and route structuring questions to your CPA. If a competitor is quoting you a confident after-tax figure without having spoken to your accountant, treat that as a warning sign.
Savannah commercial solar FAQ
Questions from Savannah business owners
Does commercial solar make more sense than residential in Savannah?
Often yes, for a structural reason. Georgia Power credits exported power at about 7.22¢ per kWh (a 3.2188¢ avoided-cost rate plus a 4¢ adder) against about 13¢ per kWh, so the value is in consuming your own production. A business that operates through daylight hours self-consumes most of what it generates, which is precisely what the current RNR Instantaneous Netting structure rewards.
What kinds of Savannah businesses do you install for?
Offices, warehouses and light industrial, retail, and multifamily properties. Low-slope membrane roofs and standing-seam metal are both common in the Savannah area and both work well. We scope each building on its own roof structure, electrical service and load profile.
Will installation disrupt our operations?
We sequence work around how you run, and most of the installation happens on the roof rather than inside occupied space. The tie-in and commissioning need a planned window, which we schedule with you rather than around you.
What commercial solar incentives are available in South Carolina?
Commercial projects are treated differently from residential, and federal commercial provisions such as 48E and depreciation treatment may apply where the expired residential credit does not. We are installers rather than tax advisers, so we document the project properly and route the structuring questions to your CPA instead of guessing.
What permits does a commercial system need in Chatham County?
A building permit and an electrical permit, with standard plan review for systems of roughly 10 kW and above, which covers essentially all commercial work. Coastal. Salt air and hurricane wind loading both apply, so attachment spacing, fastener specification and roof-penetration detailing are more demanding here than inland, and the correct hardware costs more than the catalogue default. This is the same engineering we do in Charleston, and every penetration is backed by our lifetime roof-penetration warranty. Georgia Power interconnection approval is required before energising.
How long does a commercial project take in Savannah?
It depends on system size, structural review and the interconnection queue rather than on installation time. We will give you a realistic sequence at the assessment rather than a best-case number, and we will tell you which steps are outside our control.
