Solar in Centreville, VA · as of August 2026
Centreville sits in Fairfax County and is served by Dominion Energy Virginia. Whether solar works at a given address here depends on that utility's current export terms, how much of your production you use on site, your roof's condition and orientation, and any review your community or locality applies. We confirm the utility from your bill before designing, because it decides more of the outcome than any equipment choice on a quote.
Solar in Centreville
Built for Centreville roofs, rules, and utilities
Centreville sits in western Fairfax County, served mainly by Dominion Energy Virginia with NOVEC on some addresses. Virginia’s one-for-one retail net metering applies, preserved by the State Corporation Commission in April 2026, which makes a conventionally sized array work here without storage propping it up. What most often decides an individual Centreville house is not policy but canopy: the established Fairfax neighbourhoods carry substantial mature hardwood, and this is one of the more shaded markets we work in.
Fairfax County has adopted a solar energy equipment tax exemption, and its application is more demanding than most: plans, specifications, a narrative description of what the equipment does, and the documented installed cost including materials and labour, filed with Land Development Services. It is worth having an installer who has assembled that package before. The county also reviews the permits, and the standby-charge question applies above 15 kW AC while the tariff catches up with HB 1255.
Handling the paperwork most homeowners dread is our job: HOA and architectural-review coordination, permitting, and the utility interconnection. See what our lifetime warranty covers.
You get the same crew, the same standards, and the same lifetime warranty in Centreville as anywhere else we work in South Carolina. We're a South Carolina company, headquartered in the Charleston area and built to serve homeowners statewide.
Honest numbers
What solar actually costs in Centreville
Priced at the $2.90 per watt Virginia benchmark as of August 2026, before and after $no Virginia state tax credit. Worked examples to set expectations, not a quote.
| System size | Before incentives | SC 25% credit | Net after credit |
|---|---|---|---|
| 6 kW | $17,400 | No state credit available | $17,400 |
| 9.5 kWClosest to our ~9.5 kW average system | $27,550 | No state credit available | $27,550 |
| 12 kW | $34,800 | No state credit available | $34,800 |
The number most quotes leave out: because Dominion Energy Virginia credits exported power at credited one-for-one at retail against your own annual usage rather than at retail, how much production you use on site drives your payback more than which panels you buy.
2026 incentives
What you can actually claim in Centreville
The federal residential credit ended for systems placed in service on or after January 1, 2026. Any quote still applying 30% federal is wrong, and the gap runs to thousands of dollars.
$no Virginia state tax credit did not expire. It is worth 25% of installed cost, capped at $3,500 per tax year, with a 10-year carry-forward and a further limit of 50% of your state tax liability. Qualifying systems of 20 kW or less are exempt from property tax, and equipment is exempt from state sales tax.
Dominion Energy Virginia runs no upfront residential rebate, so there is no cash-back programme to stack here. We would rather say that plainly than let you find out after signing.

Centreville specifics
What installing here actually involves
The six things that shape a Centreville design. Getting these right is most of the job, and it is where a local crew beats a national sales operation.
- 01
Your utility, confirmed per address
Most of Centreville is served by Dominion Energy Virginia, though NOVEC serves some Fairfax County addresses. It sets how your exported power is credited, which matters more than any equipment choice.
- 02
What shades your roof here
Established Fairfax neighbourhoods carry substantial mature hardwood; the newer development is more open. This is one of the more shaded markets we work in.
- 03
Mounting and structural review
Inland Mid-Atlantic. No salt exposure, with snow loading a real racking input rather than a footnote, and freeze-thaw a genuine consideration in penetration detailing.
- 04
Architectural review and HOAs
Fairfax County reviews the work. Fairfax County has adopted a solar energy equipment tax exemption, and the application is more demanding than most: it wants plans, specifications, a narrative description of what the equipment does and the documented installed cost including materials and labour, filed with Land Development Services. Under SB 504 a Virginia association may impose only reasonable restrictions on rooftop solar, unreasonable being a cost increase above 5% or a generation loss above 10%.
- 05
Outages and climate
Four genuine seasons, with summer cooling peaks aligned to peak production and lower winter output. Retail net metering smooths that across the year in a way an export-credit state cannot.
- 06
Permits in Fairfax County
A building permit and a separate electrical permit, with plan review above roughly 10 kW. We pull all of it and manage the inspection sequence.

Centreville solar FAQ
Common questions from Centreville homeowners
Who is my electric utility in Centreville?
Centreville is served mainly by Dominion Energy Virginia, with NOVEC on some Fairfax County addresses. Both operate under Virginia’s net metering statute, though a cooperative runs its own programme within that framework, so we confirm which serves your meter from your bill.
Do Centreville HOAs allow solar?
Under SB 504 a Virginia association may impose only reasonable restrictions on rooftop solar, and the statute gives bright-line tests: a restriction is unreasonable if it raises project cost by more than 5% or cuts generation by more than 10%. That turns the usual argument about street-facing panels into a numerical question. We prepare the review packet as part of every install.
Is solar worth it in Centreville?
It depends on your roof, your usage, and your utility, so there’s no single answer. no Virginia state tax credit and property-tax exemption may apply for eligible homeowners; confirm with a tax professional. A free assessment gives you real numbers for your home, not a national average.
What warranty do you offer in Centreville?
