Quick answer
Virginia solar economics depend on your roof, utility and quote. This page uses illustrative assumptions of 4.7 peak sun hours, $2.9/W and 13.0 cents/kWh; these are not verified current market averages or account rates.
Notes updated 2026-07-24
- Best for
- Virginia homeowners comparing solar costs, incentives, and payback assumptions.
- Inputs needed
- annual kWh usage, utility rate, installed $/W, net-metering policy
- Formula used
- Planning production = system kW x peak sun hours x 365 x (1 - 14.08% losses). Retail-value ceiling = production x assumed retail price; actual export value can be lower.
- Method references
- state incentive data, utility tariff checks, Wattcrunch price benchmarks
Key fact about Virginia solar
Virginia's Clean Economy Act mandates full retail net metering and sets aggressive renewable energy standards, creating a stable policy environment. Northern VA's high home values boost the financial case for solar.

Illustrative 8 kW system in Virginia
Annual production

Retail-value ceiling, not savings
$1,533
System cost (est.)
$23,200
Includes 14.08% planning losses. Valuing all production at retail is a ceiling, not a net-billing savings estimate; actual self-use, export rates and ownership costs change the result. No new Section 25D homeowner credit in 2026.
Worked example
Virginia: a transparent 8 kW planning example
This example shows how the published Virginia assumptions flow through a simple first-pass calculation.
Example household usage
10,800 kWh/year
Estimated production
11,792 kWh/year
Rate used in the example
13.0 cents/kWh
Retail-value ceiling, not bill savings

Virginia Net Metering Policy
Full retail net metering
Virginia mandates full retail net metering under the Clean Economy Act (2020). Dominion Energy and Appalachian Power must credit exports at retail. Annual true-up with net excess paid at avoided cost.
Virginia Solar Incentives
Programs require eligibility checks and cannot always be combined. Federal 25D credit is $0 for new homeowner-owned systems in 2026.
- ✓Property tax exemption on added home value (localities may opt in)
- ✓Sales tax exemption
- ✓Dominion Energy solar programs

State-specific decision guide
What to verify before signing a Virginia solar quote
In Virginia, the financial result depends on more than sunshine or the headline installation price. Confirm the export rule, program eligibility date, and interconnection timeline for your exact utility before treating a payback estimate as a promise.
Export value
This page models full retail net metering. Ask which tariff and export credit apply to your account, not only which program name appears in the proposal.
Incentive eligibility
Check equipment, income, installer, application, and placed-in-service rules before subtracting an incentive from the quote. Programs can close or change terms.
Interconnection
Budget for the published 6–12 weeks and confirm who pays for a required meter, service upgrade, or engineering review.
Source trail: production assumptions use NREL PVWatts; incentive discovery should be checked against DSIRE; electricity-market context is available from the EIA. Confirm final tax treatment with the IRS and your utility.
