Cost
What solar costs in Chantilly
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.
Chantilly arrays run large because the roofs are large. A 10 or 12 kW system on a Greenbriar or Brookfield colonial prices inside the published band with no panel line, and an EV charger fits on the same 200A panel. Shade is rarely a factor here.
| 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
Chantilly solar incentives in 2026
The federal residential credit does not apply to systems installed after December 31, 2025. What is left for a Chantilly 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 Chantilly address and exempts the equipment from property tax for five years after the inspection passes.
Net metering credits every kilowatt-hour a Chantilly array sends back at the retail rate, and the SRECs stay yours under the State Corporation Commission order of April 30, 2026.
Most Chantilly addresses net meter with NOVEC under the cooperative's own program, and the county's fee waiver and five-year property tax exemption apply to the parcel regardless of the utility.
Why an electrician
Why Chantilly homeowners choose an electrician for solar
A Chantilly roof is easy, so the difference between contractors is the electrical: the backfed breaker sized right, the disconnect where the NOVEC reviewer and the county inspector expect it, and the EV circuit run on the same visit. That is electrician work, and our master electrician is on site for it.
We file with NOVEC routinely for the western county, and the cooperative interconnection goes in the week the permit is issued. Franklin Farm and the other Chantilly associations know our packages.
The price is a cash installed number. No commissioned sales team, no subcontracted electrical, and the EV charger and the battery are itemized on one proposal.
Solar makes sense in Chantilly when
- Your Chantilly colonial has a large, open roof with little shade, which is the best solar roof in the county.
- Your bill says NOVEC and you want the cooperative interconnection filed by a contractor who does it routinely.
- You want an EV charger on the same proposal as the array, because the 200A panel has room for both.

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
For us, AJ Electric has forgotten more about electrical work then any other electrical service providers have ever known. We have used AJ Long Electric for all kinds of work at our home and they were excellent in every respect. We had them update many lights, remove old florescent lights, install outdoor security lights, change old switches to add dimmers, and help us clarify some old labels in our fuse box. The best thing about AJ Electric is THEY ARE VERY RESPONSIVE! They respond quickly to our inquiries, they email and text frequently with updates, we see an estimate for every job days before they arrive, and they text when they're on their way. Responsiveness is the most important aspect of a any business relationship and with AJ Electric it's their modus operandii. After AJ Electric arrives, their work is professional and of high quality. Their electrians work efficiently and are very mindful of being a guest in a customer's home. We have also appreciated how the AJ Electric staff, despite us having agreed to an estimate, will still consult with us before finalizing any work just in case we want any changes. Often, we have a discussion about any other options or ideas before we proceed. That degree of consideration on any home projects is great appreciated.
Chantilly solar questions
Is my Chantilly house NOVEC or Dominion?
Chantilly is Dominion or NOVEC depending on your address, and most of Chantilly is NOVEC. The top of your bill settles it. Both offer net metering, NOVEC under its own program, and we file the interconnection with whichever one serves you after the county permit is issued.
How big an array can a Chantilly roof hold?
Chantilly colonials have some of the largest, clearest roof planes in the county, and a 10 to 12 kW array is common. The bill sets the ceiling: net metering sizes a residential system to expected annual consumption, so we size to the bill and put the rest of the roof in reserve for a future EV or heat pump.
Does the Chantilly permit come from the county?
Yes. Chantilly is unincorporated Fairfax County. Land Development Services issues the residential solar permit, waives the fee, and sends the inspector. There is no town review.
Will a Chantilly HOA slow the project down?
Not if the package goes in first. Franklin Farm and several Chantilly associations review exterior changes, and Virginia Code 55.1-1820.1 keeps those reviews reasonable. We submit the layout, module color, and attachment detail to the association, then file the county permit behind the approval.

Permits, NOVEC, and Dominion in Chantilly
Chantilly has open roofs, modern panels, and NOVEC on most streets. Here is how a Chantilly solar job goes.
- 01
Chantilly is unincorporated Fairfax County, so Land Development Services issues the residential solar permit and waives the fee. Franklin Farm, on the Chantilly and Oak Hill line, and several Chantilly subdivisions run an association review for exterior changes.
- 02
Chantilly is Dominion or NOVEC depending on your address, and most Chantilly addresses are NOVEC. We read the utility off your bill and file the interconnection with the right one; the price is the same either way.
- 03
Chantilly's 1980s and 1990s colonials were built on 200A service with panels that take a backfed breaker, and the homes near Fair Lakes and Fair Oaks from the 2000s often came with EV-ready capacity. Panel work is rare here.
