Electrician-led solar company in Centreville
Solar Panel Installation in Centreville, VA
Centreville is NOVEC country for most addresses, which changes the interconnection form and nothing about the price. Its 1980s and 1990s colonials and townhomes have simple roofs and 200A panels, so the array is usually the whole job. AJ Long Electric installs the array, the panel, the battery, and the EV charger as one job, with a master electrician on site.
A master electrician is on site for every solar project. $2.40–$2.85/W installed, cash. Dominion or NOVEC depending on your address, confirmed from the bill, with the county permit and the interconnection filed by us.

Cost
What solar costs in Centreville
A typical 8 to 12 kW rooftop system installs for $19,000–$34,000 cash, which is $2.40–$2.85/W. These are cash installed prices for modules, racking, inverter, and interconnection labor. Two things keep the number down: no commissioned sales team and no subcontracted electrical.
Centreville roofs are the easy kind: 1980s and 1990s gables with a clear plane and a 200A panel below, so the array prices inside the published band with no panel line. A townhome array is smaller and prices below the typical band. A NOVEC address costs the same as a Dominion one.
| System size | Typical annual production | Installed price, cash |
|---|---|---|
| 8 kW | About 10,000 kWh | $19,200–$22,800 |
| 10 kW | About 12,500 kWh | $24,000–$28,500 |
| 12 kW | About 15,000 kWh | $28,800–$34,200 |
Production assumes about 1,250 kWh per kW per year for a typical Northern Virginia roof. Your bill and your roof set the real number.
Incentives
Centreville solar incentives in 2026
The federal residential credit does not apply to systems installed after December 31, 2025. What is left for a Centreville address is built into the proposal, and the full list with sources is in our Fairfax County incentives guide.
Fairfax County waives the residential solar permit fee for a Centreville address and exempts the equipment from property tax for five years after the inspection passes.
Net metering credits every kilowatt-hour a Centreville array sends back at the retail rate, and the SRECs stay yours under the State Corporation Commission order of April 30, 2026.
NOVEC net metering applies to most Centreville addresses under NOVEC's own program, and the county fee waiver and property tax exemption apply regardless of which utility serves the parcel.
Why an electrician
Why Centreville homeowners choose an electrician for solar
Most solar companies are set up for Dominion and treat a NOVEC address as an exception. We file with NOVEC every month for panels and EV chargers on the western side of the county, and the cooperative interconnection is routine for us.
Centreville's modern panels still need the busbar check, the backfed breaker sizing, and the disconnect placement that the county inspector looks at, and a master electrician is on site for every install to do that work right the first time.
The price is a cash installed number with no commissioned sales team inside it. The EV charger, the battery, and any HOA package are itemized on one proposal.
Solar makes sense in Centreville when
- Your bill says NOVEC and you want a contractor who files the cooperative interconnection as routinely as a Dominion one.
- Your Centreville colonial has a clear south or west roof plane and a 200A panel with room for the backfed breaker, so the array is the whole proposal.
- Your townhome roof is small and you want an honest 4 to 6 kW design sized to what the roof can hold, not a module count from a satellite photo.

What Centreville homeowners say
Google reviews from panel and EV charger jobs on the NOVEC side of the county. Solar reviews land here as installs finish.
I hired AJ Long to install a Tesla wall connector in my garage. The entire experience was fantastic! They gave me a quote over email, have a convenient system for scheduling appointments and sending text updates, arrived on time, and did an excellent job.
Evan was the best! He was fast and installed my EV charger exactly where I wanted it. He also came out to do an estimate and told me exactly what he would do and how long it would take him. He was professional and nice!
We had a great experience being able to get power restored to our house with a breaker box replacement. Visit was scheduled within a couple days and diagnostic was free. I got a reasonable quote that was right around what a couple other companies priced, but half of another competitor who did the initial assessment. Very professional electrician that got everything done in a day, and appreciated that he also helped put dry wall back up for me to spackle/paint. Felt like my options were honestly laid out and had a good discussion around the contract before repairs began. Owner felt trustworthy
Centreville solar questions
How does NOVEC net metering work for a Centreville home?
NOVEC runs its own net metering program under the Virginia statute, separate from Dominion's. We file NOVEC's interconnection application after the county permit is issued, NOVEC reviews the equipment and sets the meter, and permission to operate follows the county inspection. The State Corporation Commission order on Dominion does not govern NOVEC, so we confirm NOVEC's current terms on the account when we file.
Is every Centreville address NOVEC?
No. Centreville is Dominion or NOVEC depending on your address. Most of Centreville is NOVEC, and some addresses toward Fairfax and Chantilly are Dominion. The top of your bill settles it, and the price does not change either way.
Does a Centreville townhome qualify for the county incentives?
Yes. The permit fee waiver and the five-year property tax exemption are Fairfax County programs and apply to every Centreville parcel, townhome or detached. A townhome roof holds a smaller array, usually 4 to 6 kW, and the party-wall setback reduces the usable area, so we measure on the site visit before quoting.
Does my Centreville HOA get a say on solar?
Many Centreville associations review exterior changes. Virginia Code 55.1-1820.1 stops an association from banning rooftop solar unless the recorded declaration does, and it limits restrictions that raise the cost more than 5 percent or cut production more than 10 percent. We prepare the package with the layout, module color, and attachment detail and submit it before the county permit.

Permits, NOVEC, and Dominion in Centreville
Centreville is the county's NOVEC side, with simple roofs and modern panels. Here is how a Centreville solar job goes.
- 01
Centreville is unincorporated Fairfax County, so Land Development Services issues the residential solar permit and waives the fee. Many Centreville subdivisions have an association review for exterior changes, and Virginia Code 55.1-1820.1 keeps it reasonable.
- 02
Centreville is Dominion or NOVEC depending on your address, and most Centreville addresses are NOVEC. NOVEC runs its own net metering program under the same state statute, and we file the cooperative interconnection after the county permit.
- 03
The 1980s and 1990s colonials in Centre Ridge, Virginia Run, and Little Rocky Run were built on 200A service with panels that have busbar room, so most Centreville arrays connect without panel work.
