- Complete wiring diagram required: number of modules/strings, conductor/conduit sizing at each stage (string to combiner, combiner to inverter, inverter to back-feed breaker), DC system grounding per NEC 250.166 and 690.47(c), and location of main service/inverter/PV output meter

Tips
- The PV disconnecting means must be OUTSIDE the building nearest the point of conductor entrance, per the City's NEC 690.13(A)(1) amendment — an interior-only disconnect location does not comply.
- A Unisource Electric Letter of Approval is a hard submittal requirement in Lake Havasu City — this is specific to the local utility interconnection process, not a generic NEC requirement.
- Most PV work is classified under the City's 'Miscellaneous' plan-review category at 10 business days per the published timeframes, consistent with Arizona's A.R.S. § 9-835 municipal time-frames requirement, though systems requiring main-panel de-rating or more complex structural review may take longer at the Building Official's discretion.
