Herndon, VA Solar Energy: HOA Restrictions (2026)

The relationship between Herndon homeowners and HOAs regarding solar is governed by the Virginia Solar Freedom Act (VA Code §67-701 et seq.), the Virginia Property Owners Association Act (§55.1-1800 et seq.), and the Virginia Condominium Act (§55.1-1900 et seq.). Section 67-701 states that no community association may prohibit an owner from installing a solar energy collection device on his own property, with narrow exceptions. An association may impose reasonable restrictions concerning the size, place, and manner of placement that do not significantly increase the cost of the solar energy collection device or significantly decrease its efficiency or performance. A reasonable restriction might include requiring panels on rear or side roof slopes if solar access is equivalent, requiring dark-colored mounting hardware and frames, or requiring ground-mount systems to be screened with landscaping. Restrictions that would force panels to an inefficient orientation, require expensive custom solutions, or prohibit solar entirely are not enforceable. Many Herndon HOAs have updated their covenants to include solar standards that comply with state law. Homeowners should submit solar plans to their architectural review committee with specifications (panel dimensions, mounting location, estimated production) before installation. If an HOA unreasonably denies an application, homeowners can escalate to the HOA board, request mediation through the Virginia Common Interest Community Board, or pursue civil litigation. HOAs that prohibit solar outright or impose onerous restrictions risk liability for attorney's fees if they lose. Documentation of solar production impact from proposed restrictions (e.g., shading analysis) strengthens homeowner positions.
