. EXPEDITED PERAlIT PROCESS FOR SMALL_SCALE PV SY5TE^,{5 STANDARD STRIN\; sYsTEI.t The information in rhis guideline is intended to help local jurisd ictions and contractors identiry when PV system installations are simple, needing only a basic review, and when an installaron is more complex. lr ls likely rhar 50 % -75 % of all residential systems will comply with these simple criteria. For projects that farl to meer rhe simple criteria, resolurion sreps have been suggested to provide as a parh to permir approval. Requireil lnJormation fot Permit: l. Sire plan showing location oF major components on rhe properry. This drawing need nor be exacrly ro scale. but it should represent relative localion of components at site (see supplied example sire plan). PV arrays on dwellings wirh a S perimeter space at ndge and sides may not need separate nre servlce review. 2.
