Solar Panels in Arlington, VA: 2026 Cost, Dominion Energy Virginia Net Metering & Savings

Arlington and the bill

Arlington is Dominion Energy Virginia, not Pepco. The District line does not import DC programs. Arlington roofs are small, often shaded, and sometimes commonly owned in condominiums. Detached houses with a clear plane are the realistic projects. Dominion's net metering schedule is the export rule. Maryland and DC credit sheets do not apply. The resource is a bit lower than Hampton Roads in our table. The 2025 EIA residential average for Virginia was 15.28 cents per kWh. That statewide figure is what our calculator uses. It is not the Dominion Energy Virginia tariff. A rounded solar resource for this metro is about 4.5 peak sun hours a day.

Export credits and any SREC or REC

Dominion Energy Virginia is the usual utility for Arlington. Net metering is Dominion's schedule, not a permanent statewide statute frozen in a sales chart. Appalachian Power, which serves Roanoke and much of the southwest, is a different company. Virginia certificates can be created, and ownership should be written into the contract rather than assumed. No certificate price is quoted here because it moves.

Roofs, climate, permits, and HOAs

Colonials on small lots, townhouses, and condos. Townhouses and condos usually fail the roof-rights test. Older detached houses may need a service upgrade. A Arlington permit comes from the local building department, not from Dominion Energy Virginia. An HOA can add its own review. This page does not quote a VA permit fee or an approval, because both depend on the address. Start with roof ownership. Name Dominion, not Pepco. Ask for shade if neighboring houses or trees cover the south plane.

Estimated cost range

Estimated cost range for Arlington, labeled as an estimate and not a local quote: Berkeley Lab's August 2026 update put 2025 host-owned residential systems at about $3.60 per watt before incentives, about $3.00 per watt in the cash subset, and about $4.50 per watt in the loan subset. The median size in that set was 7.7 kW. Arlington is about 4.5 peak sun hours a day, against about 4.5 statewide. The federal residential credit under 26 U.S.C. § 25D ended for systems placed in service after December 31, 2025. The IRS treats that expenditure as made when the original installation is completed.
