EXPEDITED PERM PROCESS FOR SMALL-SCALE PV SYSTEMS STANDARD STRINc SYSTEM The information in rhis guideline is intended to help local jurisdictions and conrracrors identify when PV system insrallations systems will comply with these simple criteria. For projecas that fail rc meet the simple criteria. resolution sreps have been suggested to provide as a parh [o permir approval. Requircd Inlormation lot Perrnit: l. Site plan showing locarion of major componenrs on the property. This drawing need not be exacrly to scale, bur it should represent relarive location of componenrs ar site (see supplied example sire plan). PV arrays on dwellings with a 5 perimeter space at ridge and sides may nol need separate hre service review. 2. Electrical diagram showing PV array conhguration, wiring system. overcurren! protecrion, inverre( disconnects, required signs. and ac connection to building (see supplied standard electrical diagram). 3. Specification sheets and installation manuals (if available) for all manufacrured components including, but not limited lo, PV modules, inverter(s), combiner box, disconnects, and mounring system.
