When you need this permit
- Zoning: Accessory solar generators are a permitted (by-right) accessory use in ALL zoning districts per Natrona Next Zoning Resolution § 4.10.13 — no special use / conditional use permit needed for a single-property system serving up to that property
- Ground-mounted systems: must meet the applicable zoning district's minimum accessory-structure setback (or principal-structure setback if no accessory setback is specified)
- Ground-mounted systems: maximum height 25 feet
- Ground-mounted systems within 300 ft of an abutting ground-floor residential use require a Type A landscape buffer (per Zoning Resolution § 3.03 Buffering and Screening)
- All ground-mounted panels/equipment (except utility connection fencing/poles/wires) must be enclosed by a fence at least 6 ft high, with clearly visible voltage-hazard warning signs and wildlife-fencing style options
- Community/shared ground-mounted generators serving up to 10 property owners require a Special Use Permit from Natrona County Planning
- Electrical interconnection requires a county Electrical Permit — select 'Solar/PV Installation' as the Nature of Project
- Decommissioning: any accessory solar generator no longer producing energy or abandoned must be physically removed (all panels, structures, equipment) within 150 days of discontinued operation

Tips
- Rooftop residential solar is a permitted accessory use countywide — you do not need a zoning approval for a standard roof-mounted residential system, only the electrical permit.
- Ground-mounted systems trigger more zoning requirements: 25 ft max height, accessory-structure setbacks, a 6 ft security fence with warning signage, and a landscape buffer if within 300 ft of a neighboring residential use.
- Plan for decommissioning: an abandoned or non-producing ground-mounted system must be fully removed within 150 days per § 4.10.13(E).
Frequently asked questions
- Is a zoning permit required for rooftop solar panels in unincorporated Natrona County?
- No separate zoning/conditional use permit is required for accessory solar generators — Zoning Resolution § 4.10.13 lists 'Solar Generator, Accessory' as a Permitted (P) use in every zoning district. You still need the county's standard Electrical Permit for the interconnection work.
- Are there setback rules for a ground-mounted solar array in Natrona County?
- Yes. Per § 4.10.13(B), ground-mounted solar panels and equipment must meet the applicable zoning district's minimum accessory-structure setback (or principal setback if no accessory setback applies), cannot exceed 25 ft in height, and require a Type A landscape buffer if located within 300 ft of an abutting ground-floor residential use.
