Fairfax County is Virginia’s largest and most populous jurisdiction, and its housing stock reflects it: from Fair Oaks and Fairfax Corner colonials with generous south-facing roof planes to City of Fairfax bungalows near George Mason University, county homes tend to support larger systems (10–15 kW) than the denser inner suburbs. Virginia Code § 58.1-3661 exempts a certified solar installation’s added value from local property tax, Dominion Energy’s 1:1 net metering tariff covers the whole county, and the Virginia Solar Freedom Act protects your right to install even where an HOA might otherwise object. With the Virginia SREC market layered on, Fairfax County remains one of the highest-volume solar markets we serve — economics that no longer depend on the residential federal tax credit, which expired at the end of 2025.

Fairfax Solar FAQs
How much do solar panels cost in Fairfax County, VA?
Fairfax County’s larger lots and roof planes typically support 10–15 kW systems, generally $28,000–$42,000 before incentives — offset by the county property tax exemption and Virginia SREC income. The residential federal credit (Section 25D) expired December 31, 2025; only business installations still claim a federal credit.
Can my HOA block solar panels in Fairfax County?
No, not outright. The Virginia Solar Freedom Act limits how much an HOA can restrict solar installations — they may set reasonable placement rules, but cannot prohibit solar entirely. We help homeowners navigate HOA approval requests as part of the process.
What is the Fairfax County solar property tax exemption?
Under Virginia Code § 58.1-3661, a certified residential solar energy system’s added value is exempt from local property tax assessment, so going solar won’t raise your property tax bill.
