Solar in Sterling & eastern Loudoun · VA
Comparing solar companies in Sterling? We handle solar panel installation in Sterling from your first Dominion Energy bill review to switch-on. Sterling spans several decades of housing, so roof age varies more here than in the master-planned communities and it changes the sequence of the job.

Solar in Sterling · as of October 2026
Bill-to-size
Enter up to three recent bills. We average them, convert to kilowatt-hours at your own rate, and show the size band that covers your usage. Nothing is sent anywhere until you choose to send it.
Your size band will appear here.
Add one bill and your rate to start.
Your figures travel with the form, so you do not retype them.
An estimate for planning, not a quote. Real sizing depends on the roof planes, shade and the panel we can actually get, and we confirm it on site. The price band uses $2.90 per watt, a statewide figure. Tax treatment depends on your own liability. We are not tax advisers.
Solar in Sterling
Sterling sits in eastern Loudoun, served mainly by Dominion Energy Virginia with NOVEC on some addresses, and benefits from the same one-for-one retail net metering the State Corporation Commission preserved in April 2026. What makes it different from Ashburn or Brambleton is that it was not built all at once. The housing spans several decades, which means roof age, framing and shading all vary street by street rather than being uniform across a community.
The practical consequence is that the survey matters more here. Where a roof has under a decade left, the sensible sequence is the roof first or both together, because removing and resetting an array later is a cost paid twice. Established neighbourhoods carry mature trees while the newer development is open, so we survey rather than assume. Loudoun County permits the work outside any town limits and has adopted a solar equipment tax exemption, processed once the system is operating and fully permitted.

Sterling specifics
Six things shape a Sterling design. Getting them right is most of the job.
Most of Sterling is on Dominion Energy Virginia, but NOVEC serves some Loudoun County addresses. Your utility sets what you are paid for exported power.
A mix of established neighbourhoods with mature trees and newer open development, decided street by street rather than across the whole area.
Inland Mid-Atlantic. No salt exposure, snow loading a real racking input, and a housing stock spanning several decades so roof age varies more here than in the master-planned communities.
Loudoun County has adopted a solar equipment tax exemption, and the terms are worth knowing before you apply: the amount and duration are tied to the system’s nameplate capacity in DC watts, the equipment must be certified by the county as used primarily for collecting or generating energy, and the county will not process an application until the system is operating and has passed all required permits. Under SB 504 a Virginia association may impose only reasonable restrictions on rooftop solar, unreasonable being a cost increase above 5% or a generation loss above 10%.
Four genuine seasons, with summer cooling peaks aligned to peak production and lower winter output. Retail net metering smooths that across the year in a way an export-credit state cannot, which is the main reason a Loudoun system behaves better than its latitude suggests.
A building permit and a separate electrical permit from Loudoun County, or from the town where the address sits inside one. We pull all of it and manage the inspection sequence.
Before you sign
Look the business up with Virginia DPOR (Board for Contractors) before you sign, and ask which licence covers the electrical work in Loudoun County.
Ask who installs and who services the system in Sterling. Our own crews do both, travelling from South Carolina.
That is the unshaded ceiling for a 9.5 kW system in Sterling. A quote far above it, or one with no kWh figure, is guessing.
The quote should assume Dominion Energy's retail crediting, or the terms of whichever utility your bill names, not a national average.
A quote should say who files each one, starting with: a building permit and a separate electrical permit from loudoun county, or from the town where the address sits inside one.
How it works
We read 12 months of your Dominion Energy bills (or whichever utility your bill names) and check roof age, shade and orientation.
One Sterling design sized to your usage at the $2.90 per watt benchmark, with annual kWh sized to your annual use, since exports earn retail.
6 approvals in Loudoun County. We file all of them.
Standard structural attachment, then the Loudoun County inspections, which we book and attend.
Dominion Energy approves the interconnection and adds its about $1 a month for customers connecting under NEM 2.0 solar charge. We tell you the day you are live.
Dominion Energy also charges a standing monthly fee of about $1 a month for customers connecting under NEM 2.0 on solar accounts, which we include in payback.

Sterling solar FAQ
Most Loudoun addresses are served by Dominion Energy Virginia, with NOVEC on some. Both operate under Virginia’s net metering statute, but a cooperative runs its own programme within that framework rather than under a Commission-set tariff, so we confirm which serves your meter from your bill before designing.
The one whose licence checks out with Virginia DPOR (Board for Contractors), whose quote names Dominion Energy and states about 11,600 kWh a year for 9.5 kW, and who services what it installs. Ours does all three, with a lifetime full-system warranty.
At the $2.90 per watt benchmark, a 6 kW system is about $17,400 installed and a 9.5 kW system about $27,550. Virginia has no state solar tax credit, so there is nothing to subtract. In Sterling that 9.5 kW system makes about 11,600 kWh a year unshaded; your quote depends on roof, shade and usage.
Virginia still credits exported power one-for-one at retail against your annual usage; the State Corporation Commission preserved that for Dominion Energy Virginia customers in its 30 April 2026 NEM 2.0 ruling. Dominion Energy Virginia households paid about 14.1¢ per kWh on average in 2024, so a system sized to your own annual usage is the efficient design.
Residential solar of 25 kW or less is exempt from state and local property tax under §58.1-3661 as amended by SB 686, and many localities have adopted further exemptions by ordinance. Check with the Loudoun County assessor.
75% of Sterling homes are owner-occupied, and for owners the choice is real. Buying, with cash or a loan, means you own the system and add an asset to the house. With a lease or power purchase agreement the provider owns the panels and a buyer of your home has to take over the agreement.
Under SB 504 a Virginia association may impose only reasonable restrictions on rooftop solar, and the statute gives bright-line tests: a restriction is unreasonable if it raises project cost by more than 5% or cuts generation by more than 10%. In Loudoun’s master-planned communities that numerical test is what makes a street-facing-panel argument winnable. We prepare the review packet as part of every install.
A building permit and a separate electrical permit from Loudoun County, or from the town where the address sits inside one; An interconnection application to whichever utility serves your meter, Dominion Energy Virginia or NOVEC, on that utility’s own forms; Written confirmation of the standby-charge position for any system above 15 kW AC; HOA architectural review, which applies across most of the county’s master-planned communities, subject to the SB 504 limits. We pull every one through Loudoun County and book the inspections.

What "near me" usually means for a solar job
Distance matters less than three things: whether we are licensed in your state, which utility meters your house, and whether a crew can get back to you for service. All three are settled before we quote, not after.
