Electrician-led solar company in McLean
Solar Panel Installation in McLean, VA
McLean is unincorporated Fairfax County, and its roofs are the biggest in our service area. Large colonials with heavy usage, 400A services, and pool and EV loads make McLean the place where an electrician-led solar design matters most. 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. Fairfax County waives the solar permit fee, and we design the array around your 400A service, your EV chargers, and your battery.

What solar costs in McLean
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.
McLean arrays run large. A 12 kW system on a colonial in Langley or Chesterbrook is ordinary here, and the published band scales with it. Two 200A panels on a 400A service rarely need upgrading, so the array is usually the whole electrical line. When an older McLean home still runs a single 200A panel with no busbar room, the panel work is itemized at the published $3,500–$7,500 range.
| 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
McLean solar incentives in 2026
The federal residential credit does not apply to systems installed after December 31, 2025. What is left for a McLean 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 McLean address and exempts the equipment from property tax for five years after the inspection passes.
Net metering credits every kilowatt-hour a McLean array sends back at the retail rate, and the SRECs stay yours under the State Corporation Commission order of April 30, 2026.
Virginia Code 58.1-3661 caps the local property tax exemption at 25 kW, which covers every rooftop array we install in McLean, including the 12 kW systems the big roofs support.
Why an electrician
Why McLean homeowners choose an electrician for solar
A McLean home is an electrical system first. A 400A service, two panels, a pool, a hot tub, two EV chargers, and a whole-home battery are all loads and sources on the same service, and a solar salesperson does not design that. A master electrician does, and ours is on site for every McLean install.
Fairfax County has inspected our panel and service work in McLean since 1996. The line-side tap, the backfed breaker, and the battery transfer equipment are the details the county inspector looks at, and they are our daily work.
The price is a cash installed number with no commissioned sales team inside it. The chargers, the battery, and any panel work are itemized on the same proposal, so a McLean homeowner sees the whole system priced once.
Solar makes sense in McLean when
- Your McLean colonial has a large south or west roof plane, a 400A service, and a bill that a 10 to 12 kW array can offset.
- You already own an EV or two and want the chargers, the battery, and the array designed on one load calculation instead of three separate visits.
- Your home in Langley or Chesterbrook has mature trees on one side and you want a shade analysis before anyone quotes a module count.

What McLean homeowners say
Google reviews from service upgrade, panel, and EV charger jobs on the McLean side of the county. Solar reviews land here as installs finish.
AJ Long electric was great from start to finish. The owner who came and quoted my panel upgrade, EV charger install, and grounding install was very thorough and answered any and every question I had. Their quote was reasonably priced, and I felt comfortable.
Upgraded my fuse box and installed an EV charger wtih an additional 110 outlet. Solid estimate, timely response, excellent work. Very efficient and knowledgeable, making useful recommendations without trying to "upsell". I definitely recommend and will use them again.
They were upfront a honest with me during the troubleshooting & estimate process. When they did the actual "heavy up" and bringing our house up to code, their work was great. Professional service, I highly recommend them. We already have other projects we will be hiring them for.
McLean solar questions
My McLean house has a 400A service with two panels. Where does the solar connect?
On the panel with the busbar room and the loads that make sense, and sometimes at the service disconnect through a line-side tap. That is a design decision, not a default, and it changes the inverter location and the conduit run. We settle it on the site visit and draw it on the permit set, so the county inspector and the Dominion reviewer see the same diagram.
How big an array can a McLean home install under net metering?
Dominion allows a residential system sized up to 150 percent of the expected annual consumption at the address. McLean bills are large, so a 10 or 12 kW array usually fits inside that limit with room to spare, and we size to the bill rather than the roof.
Is McLean in Fairfax County for permits?
Yes. McLean is unincorporated Fairfax County. Land Development Services issues the residential solar permit, waives the fee, and sends the inspector. There is no town review.
Do McLean trees rule out solar?
Not usually. Langley and Chesterbrook lots have mature oaks, but most McLean roofs have at least one large plane that is clear from late morning on. We run a shade analysis on every McLean site visit and quote the modules that actually produce, so the number on the proposal is the number the roof can make.

Permits and Dominion in McLean
McLean is county jurisdiction and Dominion territory, so the paperwork is simple. The design is not, because the services are big and the loads are real. Here is how we handle a McLean address.
- 01
McLean has no town government, so Fairfax County Land Development Services issues the residential solar permit and waives the fee. There is no second office to file with.
- 02
McLean addresses are Dominion Energy Virginia. Many McLean homes run 400A services with two panels, and the interconnection has to land on the right one, which is a design decision we make on the site visit.
- 03
Usage in McLean is high. A 12 kW array is common here, and Dominion sizes net metering to 150 percent of expected annual consumption, so a big McLean bill leaves room for the full roof.
