EXPEDITED PER]VIIT PROCESS FOR SMALL.SCALE PV SYSTEMS NA ICRo-I NVERTE R The information in this guideline is inrended ro help local jurisdictions and contractors idenrify when PV system installations are simple, needing only a basic review and when an installation is more complex. It is likely that 50%-75 % of all residential systems will comply with these simple criteria. For projects that fail to meet the simple criteria, resolulion steps have been suggested to provide as a path to permit approval. Required Information Jor Permit: l. Sire plan showing location of major componenB on the properry. This drawing need not be exactly to scale, but it should represent relative locarion of components at site (see supplied example site plan). PV arrays on dwellings with a 3'perimeter space at ridge and sides may nor need separare fire service review. 2. Electrical diagram showing PV array conhguration, wiring system, overcurrent protection, inverter, disconnects, required signs, and ac connecrion to building (see supplied standard electrical diagram). 3. Specificarion sheets and insrallarion manuals (if available) for all manufacrured components including. but not limired ro. PV modules, inverter(s), combiner box, disconnects, and mounring sysrem.
