Electrician-led solar company in Oakton
Solar Panel Installation in Oakton, VA
Oakton is horse country ten minutes from our shop, with big lots, heavy tree cover along Hunter Mill Road, and a mix of 1970s colonials, 1990s estates, and new custom builds. The design starts with a shade analysis. 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. We run the shade analysis before we quote, price a ground mount when the roof cannot make the number, and file the county permit and the Dominion interconnection.

Cost
What solar costs in Oakton
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.
A clear Oakton roof prices inside the published band. A ground mount adds the foundation, trench, and conduit run and is quoted per site. Two panels on a 400A estate service rarely need work; a 1970s colonial on 150A gets the heavy-up at $3,500–$7,500. Tree work is quoted by an arborist, never buried in the array price.
| 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
Oakton solar incentives in 2026
The federal residential credit does not apply to systems installed after December 31, 2025. What is left for a Oakton 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 Oakton address and exempts the equipment from property tax for five years after the inspection passes.
Net metering credits every kilowatt-hour a Oakton array sends back at the retail rate, and the SRECs stay yours under the State Corporation Commission order of April 30, 2026.
The Fairfax County property tax exemption covers a ground-mounted array as well as a rooftop one, and Dominion's Virtual Power Plant pilot pays enrolled home batteries, which matters on an Oakton well.
Why an electrician
Why Oakton homeowners choose an electrician for solar
An Oakton solar job is a design problem before it is an install: which plane clears the oaks, whether the ground mount beats the roof, where the 400A service takes the interconnection, and how the well pump gets backed up. A master electrician answers those on site, and ours is there for the install too.
We have wired Oakton estates, barns, and well pumps from the Fairfax shop since 1996, and the county inspector who checks the disconnect and the grounding on your array is the one who checks our panels.
The price is a cash installed number. No commissioned sales team, no subcontracted electrical, and the ground mount, the battery, and any panel work are itemized on one proposal.
Solar makes sense in Oakton when
- Your Oakton home has one roof plane that clears the trees from late morning on, and you want the module count that actually produces, not the count that fits.
- Your lot has open ground with sun and a ground mount is the honest design for a heavily wooded roof.
- You are on a well and want the battery sized to keep the pump, the refrigerator, and the internet running when Hunter Mill Road loses power.

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.
Oakton solar questions
Is an Oakton roof too shaded for solar?
Some are, and we tell you on the site visit. Oakton lots along Hunter Mill Road and Vale Road carry heavy canopy, and a north-facing or fully shaded roof does not make the number. We run a shade analysis on every Oakton visit, quote only the modules that produce, and when the roof is out, we price a ground mount on the sunny part of the lot instead.
Can a ground mount work on an Oakton lot?
Yes, and Oakton is where we do them most. A ground-mounted array needs open ground with sun, a racking foundation, a trench, and a conduit run to the house, and it is quoted per site after the visit. The county permit covers it, and the property tax exemption applies to a ground mount the same as a roof array.
Who issues the solar permit in Oakton?
Fairfax County. Oakton is unincorporated county with a Vienna mailing address in places, and the parcel record settles whether the Town of Vienna review applies. Most of Oakton is outside the town limits, so Land Development Services issues the permit and waives the fee.
Does Franklin Farm review solar in Oakton?
Franklin Farm and the other planned communities on the Oakton and Herndon line review exterior changes. Virginia Code 55.1-1820.1 stops an association from banning 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 HOA package and file the county permit behind the approval.

Permits and Dominion in Oakton
Oakton is trees, wells, and big lots. Here is how we design a solar project for an Oakton address.
- 01
Oakton is unincorporated Fairfax County, so Land Development Services issues the residential solar permit and waives the fee. Franklin Farm and the other planned communities on the Oakton and Herndon line run an association review that Virginia Code 55.1-1820.1 keeps reasonable, and we prepare the HOA package.
- 02
Oakton addresses are Dominion Energy Virginia. The larger Oakton estates run 400A services with two panels, and many homes off Hunter Mill Road are on wells, so the battery design includes the well pump.
- 03
Tree canopy in Oakton is heavy. We run a shade analysis before quoting, and when the roof cannot make the number we say so and price a ground mount on the open part of the lot.
