County-Specific Requirements
Mecklenburg County (Charlotte) requires both a building permit and a separate electrical permit for solar — submit both simultaneously at mecknc.gov. Duke Energy Carolinas requires a Conditional Approval Letter (CAL) before installation can begin. Submit Duke's Distributed Energy Resource Interconnection Application at duke-energy.com at the same time as county permits. The CAL typically arrives within 15–20 business days of a complete application.
Required Permit Documents
- Completed permit application — from Mecklenburg County Land Use and Environmental Services Agency (LUESA)
- Site plan — overhead drawing, to-scale, showing panels, north arrow, setback dimensions
- Roof plan with panel layout — IFC fire setbacks (18-inch perimeter; 36-inch hip-to-ridge on hip roofs)
- Single-line electrical diagram (SLD) — all equipment by make, model, and ratings
- Equipment spec sheets — panels, inverter, racking
- Structural engineering letter — typically required over 10kW; confirm with your AHJ
- Permit fee — $200–$500 (verify current schedule with AHJ before submitting)
Utility Interconnection
Duke Energy Carolinas interconnection: submit at duke-energy.com. The CAL must be in hand before the county issues your final inspection — timeline this carefully. Duke Energy Carolinas net metering credits excess at retail rate under a 2-year minimum contract. Systems over 20kW require a supplemental engineering review.
Filing your utility interconnection application the same day as your AHJ permit application runs both reviews in parallel — saving 3–6 weeks of total timeline to Permission to Operate.

Ask your installer for the permit application or record number. Use that number to search the permit status at the Mecklenburg County Land Use and Environmental Services Agency (LUESA) online portal, or call (980) 314-2633. You want to see the permit listed as "issued" (approved) and eventually "finaled" (final inspection passed). The utility will not issue PTO until the permit is finaled — a permit stuck at "issued" means the process is not complete.
This is an unfortunately common situation. As the permit holder (the permit is in your name as property owner), you can contact Mecklenburg County Land Use and Environmental Services Agency (LUESA) directly to understand the permit's status and options for completing the required inspections with a different licensed contractor. You will need a licensed electrician or solar contractor to complete any outstanding work and schedule the remaining inspections. Keep all original permit documents and equipment spec sheets — you'll need them for the replacement contractor.
No — adding battery storage after the initial solar installation requires a new permit in most jurisdictions, including Mecklenburg County (Charlotte Metro). Battery energy storage systems require their own permit under NEC Article 706 covering the battery enclosure, electrical connections, and ventilation requirements. If you anticipate adding storage within a few years, discuss this with your installer upfront — some jurisdictions allow a combined solar + storage permit that can reduce total permitting cost and complexity.
