Solar incentives in Ashburn, VA
Ashburn solar incentives start with Dominion Energy: it pays credited one-for-one at retail against your own annual usage for exported power. After that comes the property-tax rules, since Virginia has no state solar tax credit.
The 30% federal credit ended on December 31, 2025, and Virginia has no state solar income-tax credit.
The short answer · as of August 2026
Ashburn homeowners cannot claim a Virginia state tax credit, because Virginia does not offer one. What applies instead is the property-tax exemption for residential systems of 25 kW or less, any further exemption your locality has adopted, and retail net metering. Dominion Energy Virginia credits exported power at credited one-for-one at retail against your own annual usage under net energy metering under §56-594. The 30% federal credit is no longer available.

Local incentive reality
The incentive picture in Ashburn
The incentive here is the net metering, and it is worth naming the local irony: Ashburn sits at the centre of the largest concentration of data centres in the world, load growth on Dominion’s system is a documented pressure on rates, and the same policy environment that lets those buildings draw what they draw also preserved one-for-one retail crediting for the households around them in April 2026.
Loudoun County has adopted its own solar equipment tax exemption on top of the statewide position. The terms are specific: the amount and duration scale with nameplate capacity in DC watts, and the county will not process an application until the system is operating and has passed all required permits. Virginia offers no state income tax credit for residential solar and the federal residential credit expired for systems placed in service on or after 1 January 2026. What exists instead is the mandatory property-tax exemption for residential systems of 25 kW or less under §58.1-3661 as amended by SB 686, Loudoun County’s own adopted exemption scaled to nameplate capacity in DC watts, and the retail net metering the State Corporation Commission preserved in April 2026.

What Dominion Energy Virginia pays you for solar in Ashburn
In Ashburn, Dominion Energy Virginia's export terms are worth more over 25 years than any one-off credit: 11,600 kWh a year from a 9.5 kW system, every year.
| Item | Current position (August 2026) |
|---|---|
| Programme | net energy metering under §56-594 |
| Retail rate you avoid | the applicable residential retail rate, confirmed against your own bill for power you use as you generate it |
| Export credit | credited one-for-one at retail against your own annual usage for power you send back |
| Monthly rider | about $1 a month for customers connecting under NEM 2.0 |
| Upfront utility rebate | None. There is no residential cash-back programme in this territory. |
| Who confirms your territory | We do, at the assessment. In and around Ashburn, NOVEC serves some Loudoun County addresses, and terms differ. |
The practical consequence: the gap between the retail rate you avoid and the export credit decides whether a kilowatt-hour you export is worth as much as one you use yourself. We read both off your own bill and size to your consumption rather than to your roof area.

Local factors
What changes the net value of Ashburn solar incentives
- 01
Shade in Ashburn
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.
- 02
Approvals that shape the layout
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%.
- 03
When incentives will not rescue it
Mature hardwood shades your best roof planes for much of the day, which is common in the older parts of the county.
- 04
Also worth knowing
Your roof needs replacing within about five years.
