Solar in Virginia
Virginia has rapidly transformed into one of the most promising solar markets on the East Coast, catalyzed by the Virginia Clean Economy Act (VCEA) of 2020 and the Solar Freedom Act, which removed many of the regulatory barriers that previously limited residential solar adoption. The state adopted a Virginia-specific edition of NEC 2018, which includes amendments tailored to local construction practices and climate conditions. Dominion Energy, the state's largest utility, serves most of northern and eastern Virginia, while Appalachian Power covers the western and southwestern regions — and each utility has distinct interconnection processes, rate structures, and solar program offerings. Northern Virginia's proximity to Washington, D.C. creates a unique market dynamic with high electricity rates, affluent homeowners, and strong environmental motivation driving adoption. PE stamps are required for most residential PV systems, and permitting is handled at the county or city level with significant variation in review timelines and submittal requirements across the state's independent cities and counties.
Top Jurisdictions in Virginia
| Jurisdiction | Key Requirements | Turnaround |
|---|---|---|
| Fairfax County | Fairfax County is Virginia's most populous jurisdiction and one of its most active residential solar markets. The county requires building and electrical permits with PE-stamped plan sets including site plans, structural calculations, electrical single-line diagrams, and equipment specifications. Fairfax uses an online permitting portal (FIDO) and plan review typically takes 10-15 business days. The county has been progressive in supporting solar and has dedicated staff familiar with PV plan review. | |
| Virginia Beach | Virginia Beach is an independent city with its own permitting department. Solar installations require building and electrical permits with complete plan sets. Due to its coastal location, structural calculations must account for elevated wind loads (up to 150 mph design wind speed in some areas). The city's Development Services Center handles plan review, which averages 10-14 business days. Flood zone considerations apply to ground-mount systems in low-lying areas. | |
| Norfolk | Norfolk requires building and electrical permits for all residential solar installations. As a coastal independent city, wind load requirements are significant and structural PE review is mandatory. Norfolk has been investing in permit process modernization and accepts electronic submittals. Plan review typically takes 10-15 business days. Some historic neighborhoods have additional design review requirements that can affect panel placement. | |
| Richmond | Richmond, Virginia's capital, is an independent city with a growing residential solar market. The city requires PE-stamped plans including structural and electrical drawings. Richmond's historic districts — including the Fan, Church Hill, and Monument Avenue areas — have Commission of Architectural Review (CAR) oversight that may restrict solar panel visibility and placement. Standard plan review takes 10-15 business days, with CAR review adding additional time. | |
| Arlington County | Arlington County is a dense, affluent jurisdiction adjacent to Washington, D.C. with strong solar adoption driven by high electricity rates and environmental awareness. The county requires PE-stamped plans and processes permits through its online portal. Plan review averages 7-10 business days, making Arlington one of the faster jurisdictions in Virginia. The county has been supportive of solar and has clear, well-documented submittal requirements. |

Virginia Solar Permitting FAQ
What did the Solar Freedom Act change for Virginia solar installers?
The Solar Freedom Act of 2020 made several critical changes: it lifted the 1% aggregate cap on net-metered systems (which had been limiting new installations), increased the residential net metering system size limit to 25 kW, authorized third-party power purchase agreements (PPAs) statewide, allowed community solar projects, and exempted small rooftop systems from local zoning restrictions. For installers, the most impactful changes were the PPA authorization (enabling new financing models) and the removal of the aggregate cap (eliminating the risk that net metering would become unavailable).
Does Virginia use the standard NEC or a modified version?
Virginia adopts a state-specific edition of the NEC through the Virginia Uniform Statewide Building Code (USBC). The current edition is based on NEC 2018 with Virginia-specific amendments. These amendments can affect solar installation requirements, so installers and engineers must reference the USBC — not just the base NEC. The Virginia Department of Housing and Community Development publishes the current code edition and all amendments on its website.
How does the interconnection process differ between Dominion Energy and Appalachian Power?
Dominion Energy and Appalachian Power each have their own interconnection application, technical requirements, and timelines. Dominion Energy has an online interconnection portal and generally processes residential applications within 30-45 days. Appalachian Power's process is less standardized and may take longer. Technical requirements — including approved inverter lists, metering configurations, and disconnection switch placement — differ between the utilities. Installers operating in both territories need separate workflows and should verify current requirements directly with each utility.
Are there wind load requirements for coastal Virginia solar installations?
Yes. Coastal Virginia jurisdictions including Virginia Beach, Norfolk, Hampton, and Newport News require elevated design wind speeds per ASCE 7, ranging from 130-150 mph depending on the exact location and risk category. Structural PE calculations must account for these loads, which affect racking selection, attachment spacing, and roof structural adequacy. Some racking systems may not carry ratings for coastal Virginia wind speeds, so equipment selection must be coordinated with the structural engineering review.
Do historic districts in Virginia restrict solar panel installation?
Yes. Virginia's historic districts — including areas in Richmond, Alexandria, Fredericksburg, Williamsburg, and other cities — may have architectural review boards that regulate exterior modifications including solar panels. Restrictions can include prohibitions on street-visible panels, requirements for specific mounting methods, or limits on panel coverage area. In Richmond, the Commission of Architectural Review (CAR) must approve solar installations in designated historic districts. Installers should check for historic district overlay zoning early in the project and factor potential design restrictions into their proposals.
What property tax treatment applies to solar installations in Virginia?
Virginia state law authorizes local governments to exempt solar energy equipment from property taxation, but each locality must individually adopt this exemption. Many jurisdictions — including Fairfax County, Arlington, Alexandria, and others — have done so. However, some localities have not adopted the exemption, meaning solar equipment could increase the assessed value of the property and result in higher property taxes. Installers should verify the property tax treatment in each project's specific locality and only include the exemption in savings calculations when it has been formally adopted.
