. EXPEDITED PERATIT PROCESS FOR SMALL-SCALE PV SYSTEiIIS STANDARD STRINC SYSTENT The information in rhis guideline is intended ro help local jurisdictions and contraclors identify when PV sysrem installations are simple, needing only a basic review, and when an installaflon is nrore complex Ir is likely rhar 50%-75% ofall residential systems will comply with these simple cri(eria. For projecB rhat fail to meet rhe simple criteria. resolution steps have been suggested to provide as a path to permit approval. Requi"ed hformdtion Io?
