EXPEDITED PERIV1IT PROCESS FOR SMALL-SCALE PV SYSTEMS <br />STANDARD STRINC SYSTEI"I <br />The information in rhis guideline is intended to help local jurisdicrions and conrracrcrs identify when PV sysrem insrallarions <br />are simple. needing only a basic review, and when an insEllarion is more complex. lt is likely rhat 50%.75% of all residenrial <br />systems will comply with these simple crireria. For projecrs rhat fail to meet !he simple criteria. resolurion steps have been <br />suggesred ro provide as a parh (o permir approval <br />Required InJormation Jor Pennit: <br />l. Site plan showing locarion of major components on rhe property. This drawing need not be exacdy ro scale, bur it <br />should represent relat,ve location of componenrs ar site (see supplied example sire plan). PV arrays on dwellings <br />wirh a 5 perimeter space at ridge and sides may not need separate fire service review. <br />2. ElecLrical diagram showing Pv array connguration. wiring system. overcurrent protection, inverrc( disconnects, <br />required signs. and ac connecrion ro building (see supplied srandard elecrrical diagram). <br />5. Specihcation sheets and installation manuals (iF available) For all manufactured components including, but not <br />limited to, Pv modules, inverter(s), combiner box. disconnecrs. and mounring system. <br />Step 1 : Svuctural Review o[ PV Array Mounting System <br />Is the aray to be mounted on a defined, permitted rcof structur€?
