The Local Government Outreach Group (LOG), convened by the Virginia Department of Environmental Quality, developed two model zoning ordinances: the first for smaller-scale solar energy projects and the second for larger-scale projects. These ordinances define both smaller- and larger-scale projects as (1) those that generate electricity from sunlight using one or more photovoltaic systems and other appurtenant structures and facilities onsite, OR (2) those that utilize sunlight as an energy source to heat or cool buildings or water or produce electrical or mechanical power by collecting, transferring, and/or converting solar-generated energy. The model ordinances’ definitions also delineate how these projects differ. A smaller-scale project is defined as one that (1) has a disturbance zone equal to or less than two acres, (2) is mounted on or over a building or parking lot or other previously-disturbed areas, OR (3) utilizes integrated photovoltaics only. A larger-scale project is defined as any solar energy project that does not meet these criteria.
