The maximum height of panels, buildings, structures, and other components of a solar facility is 20 feet, as measured from the highest natural grade below each element.
- Maximum heightMaximum heightThe tallest a building may be, given in feet, in storeys, or both — whichever binds first. of lowest edge of ground-mounted PV panels10 ft
The maximum height of the lowest edge of all ground-mounted photovoltaic panels is ten feet as measured from the finished grade.
Lighting
- Outdoor lighting restrictions
Except for any outdoor lighting required by federal law: a. Outdoor lighting is permitted only during maintenance periods. b. Regardless of the lumens emitted, each outdoor luminaire must be fully shielded to the standard of section 4.17.

Accessory solar energy facilities, whether roof- or ground-mounted, are subject to the applicable structure setbacks of the zoning district in which the facility is located.
- Airport notice and glint/glare study
Any solar energy facility with greater than one acre of fenced area within five nautical miles of a licensed airport must provide the Chief Operation Officer of the airport with both (i) written notice stating the system's location, technology to be used, and total land coverage; and (ii) a glint/glare study.
- Battery energy storage setbacksSetbackThe distance a building must be held back from a lot line.
Battery energy storage facilities must have the following setbacks: a. 100 feet from adjacent parcels not under common ownership, and all public rights-of-way; and b. 300 feet from dwellings on adjacent parcels not under common ownership.

Notwithstanding any exemption in County Code Chapter 17, all ground-mounted energy facilities whose total land disturbance area, including the horizontal projected areas underneath panels, is at least 10,000 square feet, must comply with County Code Chapter 17.
- Decommissioning requirements
Solar facilities that have reached the end of their operation or have not been in active and continuous service for a period of six months must be removed at the owner's or operator's expense. Decommissioning must include removal of all electric systems, buildings, cabling, electrical components, security barriers, roads, foundations, pilings, and any other associated facilities, so that any agricultural ground upon which the facility and/or system was located is again tillable and suitable for agricultural uses.
- Fence heightMaximum heightThe tallest a building may be, given in feet, in storeys, or both — whichever binds first. range96 in
Any fencing on the interior of the buffer/screening area of ground-mounted energy facilities may not be at a height of less than 61 inches or greater than 96 inches (inclusive of razor/barbed wire).
- Fire access separation between rows
Energy facilities must maintain sufficient separation between rows of photovoltaic panels or battery energy storage facilities to provide fire access and meet clear zone requirements.
- SetbacksSetbackThe distance a building must be held back from a lot line. for facilities with >21 fenced acresacre43,560 square feet — about the size of an American football field without the end zones.
Ground-mounted solar energy facilities with greater than 21 fenced acres, are subject to the following setbacks: a. 100 feet from adjacent parcels, not under common ownership, and all public rights-of-way; and b. 300 feet from dwellings on adjacent parcels, not under common ownership.
- Maximum fenced area for by-rightBy rightPermitted outright: if the plans meet the written rules, permission cannot be withheld. solar in RA21 acresacre43,560 square feet — about the size of an American football field without the end zones.
By-right ground mounted solar energy facilities in the Rural Areas (RA) zoning district are limited to a maximum of 21 acres of fenced area on any parcel in existence at the time of adoption of this ordinance.
- Prime farmland disturbance limit10 acresacre43,560 square feet — about the size of an American football field without the end zones.
By-right projects must not disturb either (a) more than 10 acres of prime farmland (as determined/identified by the United States Department of Agriculture's Natural Resources Conservation Service) and/or (b) areas used for an agricultural activity within the five years preceding an application, unless portions of the parcels used for the facility will continue to be used for an agricultural activity.
- Screening for facilities with >=10 acresacre43,560 square feet — about the size of an American football field without the end zones.
Energy facilities with a fenced area of at least ten acres must be screened from public streets and abutting parcels not under common ownership. Screening provided must meet the screening level provided by a triple staggered row of evergreen trees and screening shrubs planted 15 feet on center with screening shrubs making up not more than 33 percent of the plantings and equally dispersed.
- Site plan exemption
Notwithstanding section 32.2, a site plan is not required for an energy facility, but the energy facility is subject to the requirements of section 32.
- Transmission line placement
Any new associated electrical transmission lines, whether connecting internal portions of the project or connecting to a switchyard, substation, or point of interconnection, and whether above or below ground, must be located in a manner to minimize intrusiveness and mitigate their impact to surrounding parcels.
From the ordinance
