It is likely that 50%-75% of all residenrial systems will comply with these simple criteria. For projects that fail to meet the simple criteria, resolurion steps have been suggested to provide as a path to permir approval. Requircd It{ortnntion Jor I'ertntt : l. Site plan showing location of major components on the property. This drawing need nor be exactly 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 separaae hre service review. 2. Electrical diagram showing Pv array conhguration, wiring system, overcurrent protection, invener, disconnects, required signs, and ac connection to building (see supplied srandard elecrrical diagram). 3. Specihcation sheets and insEllation manuals (if available) for all manufactured components including, bur nor limited to, PV modules, inverrer(s), combiner box. disconnects. and mounting system.
