Cost
What solar costs in Sterling
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 Sterling roof array prices inside the published band. A ground mount adds the footings, the trench, and the conduit run to the house, each on its own line, plus the Loudoun zoning permit. When a Sterling home needs a heavy-up before the backfed breaker fits, it is priced on the same proposal at $3,500–$7,500.
| 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
Sterling solar incentives in 2026
The federal residential credit does not apply to systems installed after December 31, 2025. What is left for a Sterling address is local, and every item below is built into the proposal.
Loudoun County takes 100 percent of the value of a residential Sterling array, up to 25 kW, off the real estate assessment for every year it stays in service.
NOVEC net meters under its own program for NOVEC addresses in Sterling, and Dominion credits exports one for one with the SRECs kept by the owner under the April 30, 2026 SCC order.
Loudoun certifies the equipment through Building and Development after the permits pass, and the Commissioner of the Revenue applies the exemption, so the permit record we file is the record the exemption starts from.
Why an electrician
Why Sterling homeowners choose an electrician for solar
A Sterling ground mount is mostly electrical work: a trench, a conduit run, a disconnect at the array, and a feeder back to the panel. A solar company hands that to a subcontractor. We are the electrical contractor, and a master electrician is on site for every Sterling install, roof or ground.
We build the Loudoun packet the way the county lists it: wet-sealed plans with the array layout, the wiring, the overcurrent protection, the inverter, the disconnects, and the signs, plus the spec sheets for every component. When the reviewer has a comment, we answer it ourselves.
The number is a cash installed price with no commission inside it. The ground mount, the trench, the heavy-up, and the EV charger are separate lines, so a Sterling homeowner can see what each piece costs before choosing.
Solar makes sense in Sterling when
- Your Sterling home has a roof plane facing south or west with little shade, and you want a cash price for the array with the permits filed for you.
- Your lot has open ground and the roof does not, and you want the ground mount, the zoning plat, and the trench to the house designed by the electrical contractor.
- Your panel is full or still on 100A service, and you want the heavy-up and the array on one proposal and one county inspection sequence.

What Sterling homeowners say
Google reviews from heavy-up, panel, and EV charger jobs on the Loudoun side of Route 28. 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
Sterling solar questions
Does Sterling have its own solar permit office?
No. Sterling is unincorporated Loudoun County, so the county Department of Building and Development issues the building and electrical permits through LandMARC. We submit the wet-sealed plans and the spec sheets for the modules, the inverter, the disconnects, and the racking, and we book the county inspection.
Is my Sterling house Dominion or NOVEC?
The top of your electric bill settles it. Sterling is Dominion or NOVEC depending on your address, NOVEC lists Loudoun in its territory, and both utilities run net metering. We file the interconnection with whichever one serves you, and the Loudoun permit is the same either way.
Can I put a ground-mounted solar array in my Sterling yard?
Yes, when the lot has the room. Loudoun adds a zoning permit and a plat that places the array against your property lines, and the construction drawings show footing details instead of roof attachments. We draw both, and the trench and conduit run to the house are itemized on the proposal.
When does the Loudoun solar tax exemption start for a Sterling home?
The tax year after you apply or the tax year after all permits are complete, whichever is later. Loudoun exempts 100 percent of a residential system's value up to 25 kW while it stays in service, and the county can ask from time to time for proof that the system is still running.

Loudoun permits, Dominion, and NOVEC in Sterling
Sterling is simple on jurisdiction and split on utility. Here is how a Sterling solar job goes, roof or ground.
- 01
Sterling is unincorporated Loudoun County with no town permit office. The building permit and the electrical permit come from the Department of Building and Development through LandMARC, and the inspector comes from the county.
- 02
Sterling is Dominion or NOVEC depending on your address. NOVEC lists Loudoun in its service territory and runs a Loudoun Service Center, and Loudoun's solar page points owners to both utilities for net metering.
- 03
A ground-mounted array on a larger Sterling lot adds a Loudoun zoning permit and a plat showing the array against the property lines, and the drawings show footing details instead of roof attachments. A roof array skips the zoning permit.
