EXPEDITED PERMIT PROCESS FoR SMALL-SCALE PV SYSTEMS STANDARD STRINC SYSTEM The information in this guideline is inlended ro help local jurisdicrions and conrractors identify when pv sysrem insmllations are simple, needing only a basic review. and when an inshllation is more complex. Ir is likely thar 50 % -75 % of all residential systems will comply with these simple criteria. For projecrs that fail ro meer the simple crireria, resolution steps have been suggesled to provide as a parh ro permit approval. Required. Infonnation for Pemit: l. Sire plan showing location ol malor components on rhe properry. Thjs drawing need not be exacrly ro scale, but ir should represent relative locarion of componenrs ar sire (see supplied example sire plan). pV arrays on dwellings with a 3'perimeter space at ridge and sides may nor need separate frre service review 2 Electrical diagram showing PV array conhguration, wiring system, overcurrent prorection, invertet disconnecrs, required signs, and ac connecrion to building (see supplied standard electrical diagram) 3 Specification shee6 and installation manuals (if available) lor all manufactured components including. but nor limited to, PV modules, inverter(s), combiner box, disconnects. and mounring system.
