. EXPEDITED PERMIT PROCESS FOR SMALL-SCALE PV SYSTEUS MICRo-INVERTER The informarion in this guideline is intended ro help local jurisdicrions and contractors idenrify when pV sysrem installarions are simple, needing only a basic revieq and when an insallation is more complex. Ir is likely thar SOX -liX of all residenrial systems will comply wirh these simPle criteria. For projec6 that fail to meet the simple criteria. resolurion steps have been suggesred ro provide as a parh ro permir approval. Required Information Jot Perrnit: l. Site Plan showing locarion of major components on the propeny. This drawing need not be exacrly ro scale, but ir should represent relarive location of components ar sire (see supplied exampla sire plan). pV arrays on dwellings with a 3 perimeter space a( ridge and sides may not need separate fire service review. 2 Electrical diagram showing PV array configuration. wiring system, overcurrent protection, invene( disconnects, required signs, and ac connection ro building (see supplied sandard elecrrical diagram). 3. specifrcation sheets and installation manuals (if available) for all manufactured components including, but not limited fo, PV modules. inverter(s), combiner box, disconnects, and mounting system Step 1 : Structural Review o[ PV Array Mountins System ts tllc array to be mountcd on a dcfined, permittcd mof structutr?
