- Install conventional rooftop or ground-mount solar through the standard interconnection process.
✕ Not yet / not allowed

Before you plug in: North Dakota checklist
- The rule that applies is North Dakota Public Service Commission (IOUs only)'s interconnection process: N.D.A.C. 69-09-07 net energy billing (1991).
- A plug-in kit falls in the smallest tier (<=100 kW). Not verified ($100 per third party).
- Permits: State Electrical Board inspects statewide; 2026 NEC.
