Electrician-led solar company in Vienna

Solar Panel Installation in Vienna, VA

Vienna is fifteen minutes from our shop on Dorr Avenue, and the town's teardown boom has put hundreds of new 200A, EV-ready panels under roofs that were designed with solar in mind. 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 file the Town of Vienna zoning review, the Fairfax County permit, and the Dominion interconnection for you.

Cost

What solar costs in Vienna

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.

Vienna roofs split two ways. The new builds along Maple Avenue's side streets have big, simple gable roofs and 200A panels, so the array is the whole job. The 1950s and 1960s ramblers and colonials in Vienna Woods often need a heavy-up first, priced on the same proposal at the published $3,500–$7,500 range.

Installed prices by system size
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

Vienna solar incentives in 2026

The federal residential credit does not apply to systems installed after December 31, 2025. What is left for a Vienna 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 Vienna address and exempts the equipment from property tax for five years after the inspection passes.

Why an electrician

Why Vienna homeowners choose an electrician for solar

A Vienna teardown is a good solar candidate because the electrical is already modern. What the solar company still subcontracts is the interconnection at that panel, the disconnect on the wall, and the inspection. We are the electrical contractor, so nobody is subcontracted and the person responsible for the electrical is on your roof.

We have pulled permits inside the Town of Vienna and with Fairfax County for thirty years. The town zoning review and the county building permit are two different desks, and a homeowner who has never filed with either does not want to learn the order the hard way.

The price is a cash installed number with nothing hidden in it. No commissioned salesperson, no subcontracted electrical, and the EV charger or battery is itemized on the same proposal instead of appearing as a change order after the array goes up.

Solar makes sense in Vienna when

Your Vienna new build or teardown replacement came with 200A service and an EV-ready panel, so the array is the only electrical work on the proposal.
Your older Vienna Woods or Wolf Trap colonial is still on 100A or 150A service and needs the heavy-up we already do every week.
You want the town zoning review and the county permit handled by one contractor instead of coordinating two offices yourself.

What Vienna homeowners say

Google reviews from panel, heavy-up, and EV charger jobs across the Vienna area. 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.

John Gore, Google review

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!

Mari P, Google review

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

Vienna solar questions

Does a Vienna solar project need a town permit and a county permit?

Inside the town limits, yes. The Town of Vienna Planning and Zoning department reviews the project for zoning compliance, and Fairfax County issues the building and electrical permit and sends the inspector. We file with both offices and schedule the inspection. A Vienna mailing address outside the town limits only sees the county.

My Vienna house is a new build with a 200A panel. Is it ready for solar?

Usually. Most Vienna teardown replacements from the last ten years have 200A service, a panel with busbar room for a backfed breaker, and an EV circuit already run. We confirm the busbar rating and the breaker slots on the site visit, and when the panel is ready the array is the only electrical line on the proposal.

How does Solarize Vienna compare to your price?

Solarize Virginia is a co-op program the town promotes, and it is a fair way to shop. Our published band is $2.40–$2.85/W installed for cash with a master electrician on site and the panel, battery, and EV charger on the same proposal. Bring the co-op quote and we will compare it line by line.

Permits, the town, and Dominion in Vienna

Vienna is a town inside Fairfax County, so the zoning review is the town's and the building permit is the county's. Here is how the two fit together for a Vienna address.

01
Inside the Town of Vienna the Department of Planning and Zoning reviews the project for the town zoning code before Fairfax County issues the building and electrical permit. Two offices, one package, and we file both.
Town of Vienna: Permits and Applications Fairfax County: Residential Solar Permits
02
Vienna addresses are Dominion Energy Virginia. We read the account off your bill, file the interconnection, and request permission to operate after the county inspection passes.
Dominion Energy Virginia: Net Metering
03
The town promotes Solarize Virginia, the co-op program run by the Local Energy Alliance Program. Our published cash band stands on its own, and we are happy to price against a co-op quote line by line.
