County incentives
Permits, exemptions and the City of Fairfax
Fairfax County waives its permit fee for residential solar and offers a five year property tax exemption on the solar equipment. Inside the City of Fairfax, a separate ten year exemption applies. Statewide, Virginia also exempts residential systems up to 25 kW from property tax and exempts solar equipment from sales tax.
We check which jurisdiction your address falls under before pricing, since the city and county handle permits separately.
Which utility
Dominion or NOVEC
Most of Fairfax County is Dominion territory, where Virginia's April 30, 2026 order kept one-to-one net metering and applications approved before May 1, 2027 stay on current terms. In the western part of the county, NOVEC serves customers with its own net metering program and its own paperwork.
Your bill tells us which one applies. We file with the right utility and design the system around that utility's rules.
How a job runs
From the permit desk to Dominion or NOVEC

After installation and inspection, the utility grants permission to operate and we set up monitoring and register the system's Virginia credits.
