EXPEDITED PEI{MIT PIIOCESS FOR SMALL-SCALE PV SYSTEMS STANDARD STRINC SYSTEM The informarion in rhis guideline is intended to help local jurisdicrions and contractors identify when Pv system installarions are simplg needing only a basic review, and when an installalion is more complex. It is likely that 50 %-759 of all residential sysEms will comply with these simple crireria. For projects that fail to meet the simple crireria, resolu on sreps have been suElgested to provide as a path to permit approval. Requbed lr{oflnation for Permit: l. Ste plan showing location of major components on the properry. This drawing need not be exacdy to scale, but it should represent relative location oF components at site (see supplied example site plan). PV arrays on dwellings with a 3' perimeter space at ridge and sides may not need separate hre service review. 2. Electrical diagram showing PV array conhguration, wiring system, overcurrent prorection, inverter, disconnects, required signs, and ac connefiion to building (see supplied srandard elecrrical diagram). 1. Specificarion sheets and inshllation manuals (if available) for all manufactured components including. but not limi[ed to, PV modules, invener(s). combiner box, disconnects. and mounting system.
