Bill-to-size
What size system does your Ashburn bill need?
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 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 companies in Ashburn: what is different here
Ashburn sits at the centre of the largest concentration of data centres on the planet, and that has a direct bearing on why a homeowner here might be reading a solar page at all. Load growth on Dominion Energy Virginia’s system is a documented pressure on rates, which means the bill climbing on your kitchen table is connected to the buildings a few miles down the road. Solar is one of the few responses available to a household that has no say in that. What makes it work here rather than merely appealing is the policy: Virginia kept one-for-one retail net metering when the State Corporation Commission ruled on Dominion’s NEM 2.0 filing on 30 April 2026, so an array sized to your annual consumption captures close to full value.
Ashburn is master-planned, which cuts both ways and mostly in your favour. Thousands of near-identical modern roofs mean the structural work is predictable and the shading survey is quick, and most of them are open rather than under canopy. Against that, almost every community here has architectural guidelines. SB 504 limits what an association may restrict, with a cost increase above 5% or a generation loss above 10% being unreasonable, which turns the usual argument about street-facing panels into a numerical question. Loudoun County has also adopted a solar equipment tax exemption, scaled to nameplate capacity in DC watts and processed only once the system is operating and fully permitted.

- Only 37% of homes are single-family detached. In townhomes and condos the association or shared roof decides first, so we check governing documents before anything else.
- 11,694 Ashburn households own their home, the ones who can install and claim the system as an asset.

Ashburn specifics
What installing in Ashburn actually involves
Six things shape a Ashburn design. Getting them right is most of the job.
- 01
Your utility, confirmed per address
Most of Ashburn is on Dominion Energy Virginia, but NOVEC serves some Loudoun County addresses. Your utility sets what you are paid for exported power.
- 02
What shades your roof here
Ashburn is master-planned and largely open, with thousands of near-identical modern roofs. That uniformity is a genuine advantage: the shading survey is quick and the structural work is predictable.
- 03
Mounting and structural review
Inland Mid-Atlantic. No salt exposure, with snow loading a real racking input. The roof stock is recent enough that framing is rarely the constraint; the care goes into flashing detail and freeze-thaw.
- 04
Architectural review and HOAs
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%.
- 05
Outages and climate
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.
- 06
Permits in Loudoun County
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
How to choose a solar company in Ashburn

The licence covers the work

About 11,600 kWh a year, in writing
That is the unshaded ceiling for a 9.5 kW system in Ashburn. A quote far above it, or one with no kWh figure, is guessing.
- 4
Dominion Energy, by name
The quote should assume Dominion Energy's retail crediting, or the terms of whichever utility your bill names, not a national average.
- 5
The 6 Loudoun County approvals
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.

- 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
- An additional electrical permit where battery storage is included
- A county application for the solar equipment tax exemption once the system is operating and fully permitted
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.

Ashburn solar FAQ
Common questions from Ashburn homeowners
Who is my electric utility in Ashburn?
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.
What is the best solar company in Ashburn, VA?
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.
How much do solar panels cost in Ashburn?
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 Ashburn that 9.5 kW system makes about 11,600 kWh a year unshaded; your quote depends on roof, shade and usage.
Does Ashburn have net metering?
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.
Will solar raise my property taxes in Ashburn?
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.
Should I lease or buy solar in Ashburn?
69% of Ashburn 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.
Do Ashburn HOAs allow solar panel installation?
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.
What permits does solar panel installation in Ashburn need?
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.
