Virginia Property Tax Exemption for Solar Energy Systems

Virginia's property tax exemption for solar energy systems removes a significant financial barrier to residential and commercial solar adoption by ensuring that the added value a solar installation contributes to a property does not increase the owner's annual property tax bill. Authorized under Virginia Code § 58.1-3661, the exemption applies to certified solar energy equipment, facilities, and devices. Understanding how this exemption is structured, who qualifies, and where its limits lie is essential for any property owner evaluating the full economic picture of a solar investment in the Commonwealth.

Definition and scope

Virginia Code § 58.1-3661 classifies solar energy equipment, facilities, and devices as a separate category of property and grants localities the authority to exempt or partially exempt them from local real property taxation. The statute defines qualifying equipment as machinery and equipment used primarily for the purpose of transforming solar energy into thermal, mechanical, or electrical energy.

The exemption is structured as a local option, meaning individual counties, cities, and towns must adopt an ordinance to activate the benefit for their residents. As of the most recent Virginia Department of Taxation guidance, the majority of Virginia's localities have enacted such ordinances, but coverage is not universal. Scope and coverage limitations are therefore geographically bounded: a property owner in a locality that has not passed an enabling ordinance receives no automatic state-level exemption on real property tax, even though the state statute permits it.

What falls outside this exemption's scope includes:

1. Personal property taxes, which are governed by separate locality rules
2. Sales and use taxes on solar equipment purchases (addressed separately under sales tax exemption for solar equipment in Virginia)
3. Federal tax obligations, which are governed entirely by Internal Revenue Code provisions, not Virginia law
4. Utility-scale solar projects assessed under the Virginia Department of Taxation's Public Service Corporation procedures rather than local real property assessment rolls

The page does not address interconnection requirements, net metering agreements, or utility tariff structures. Those topics are covered in resources such as the regulatory context for Virginia solar energy systems.

How it works

When a qualifying solar installation is added to a property, the locality's assessor normally would increase the assessed value of the parcel to reflect the improvement — just as a new deck or finished basement would raise the taxable value. Under § 58.1-3661, localities that have adopted the enabling ordinance instead exclude the value attributable to the certified solar system from the taxable assessment, holding the property's taxable value at the pre-installation baseline.

The mechanism operates in a structured sequence:

1. Installation and inspection: The solar system is installed and passes all required electrical and building inspections under the Virginia Uniform Statewide Building Code (USBC), administered by the Virginia Department of Housing and Community Development (DHCD). Permitting concepts specific to solar installations are detailed at permitting and inspection concepts for Virginia solar energy systems.
2. Certification application: The property owner submits documentation to the locality demonstrating that the equipment meets the statutory definition of solar energy equipment under § 58.1-3661.
3. Assessor review: The local assessor confirms eligibility, determines the value attributable to the solar system (often using contractor invoices, appraisal data, or a set methodology established by the locality), and excludes that value from the taxable assessment.
4. Annual reassessment: In localities conducting annual or biennial reassessments, the exempted value is reviewed on the same cycle as the rest of the property assessment.

The exemption applies to both rooftop photovoltaic systems and ground-mounted arrays, provided the equipment serves the property in question. Battery storage systems may qualify if they are integral to the solar installation and documented as part of the same energy facility; standalone storage additions require separate review. For context on how solar energy storage fits into the broader system design, see solar energy storage batteries in Virginia.

Common scenarios

Residential rooftop system, participating locality: A homeowner in Fairfax County installs a 10-kilowatt rooftop photovoltaic system. Fairfax County has adopted an ordinance under § 58.1-3661. The assessor receives the certification documentation, values the system at approximately $25,000 based on installed cost, and removes that $25,000 from the property's taxable assessed value. At Fairfax County's 2024 residential tax rate of $1.135 per $100 of assessed value (Fairfax County Department of Tax Administration), the homeowner avoids roughly $284 in annual property tax on the solar equipment.

Commercial ground-mount system, participating locality: A small business installs a 100-kilowatt ground-mounted array. Because commercial properties are assessed at the same local rates as residential properties under Virginia's unified real property assessment framework, the commercial owner applies the same § 58.1-3661 process. Commercial systems generate larger absolute tax savings due to higher system values, making the exemption proportionally significant for business-case modeling alongside options such as solar financing options in Virginia.

Residential system, non-participating locality: A homeowner in a locality that has not enacted an enabling ordinance installs the same 10-kilowatt system. Virginia Code § 58.1-3661 authorizes but does not mandate the exemption. The assessor in a non-participating locality will include the solar system's added value in the taxable assessment. The homeowner has no statutory right to an exemption unless the locality subsequently adopts an ordinance.

Agricultural installation: A farm operator installs solar panels on agricultural land. Depending on locality-specific ordinance language, agricultural solar may qualify under § 58.1-3661 or may be subject to separate land-use assessment rules under Virginia's Agricultural and Forestal Districts framework. Agricultural solar installations in Virginia provides additional classification guidance for farm-based systems.

Decision boundaries

Three primary classification boundaries determine whether a property owner receives the full exemption, a partial exemption, or no exemption:

Locality participation vs. non-participation: The threshold condition is whether the property is located in a locality with an active § 58.1-3661 ordinance. Property owners should confirm ordinance status directly with their county or city assessor's office before purchase decisions.

Qualifying equipment vs. non-qualifying equipment: Equipment must primarily serve the function of transforming solar energy into usable energy as defined by the statute. Decorative solar features, solar-powered landscape lights hardwired to a separate low-voltage system, or solar pool heaters may or may not qualify depending on how the locality interprets the primary-purpose standard. Equipment must pass inspection under the USBC and hold a valid building permit to be documentable as a certified installation.

Full exemption vs. partial exemption: Some localities have adopted ordinances that grant only partial exemption — for example, exempting 80% or 50% of the solar system's assessed value rather than 100%. The Virginia Department of Taxation (tax.virginia.gov) publishes guidance on locality-level ordinance variations. Checking the specific ordinance language, rather than assuming full exemption, is the operationally correct approach.

The property tax exemption interacts with other Virginia incentive structures. It is distinct from the federal Investment Tax Credit (ITC) administered under Internal Revenue Code § 48 or § 25D, which is a federal income tax credit with no state property tax component. It is also separate from the Virginia income tax subtraction for solar equipment, and from the Virginia Clean Economy Act compliance mechanisms that apply to regulated utilities.
