EXPEDITED PERMIT PROCESS FOR SMALL-SCALE PV SYSTEMS STANDARD STRINC SYSTEM The information in this guideline is intended to help local jurisdictions and contractors identifi/ when PV system installations are simple. needing only a basic review and when an insEllation is more complex lt is likely rhat 50%-75% of all residenrial systems will comply with these simple criteria. For proJects that fail to meet the simple criteria, resolution steps have been suggested to provide as a parh to permit approval Required InJormation for Permit: I Site plan showing location of major components on the property. This drawing need not be exactly ro scale. bur ir should represent relative location of components at site (see supplied example site plan). PV arrays on dwellings with a 3 perimeter space al ridge and sides may not need seParate fire service review. 2 Electrical diagram showing PV array conhguration. wiring systern, overcurrenr proleclron, rnverte( disconnects, required signs, and ac connection ro building (see supplied standard electrical diagram) 3 Specihcation sheets and insrallarion manuals (if available) For all manufacrured componenrs including. but nol Iimited to, PV modules, inverter(s), combiner box, disconnects. and mounring system.

Step 2: Electrical Review o[ PV System (Calculations for Electrical Diagram) ln order for a PV system to be considered for an expedited permit process, tlle following must apply: I PV modules. utility-interactive inverlers. and combiner boxes are identified for use in PV systems. 2 The PV array is composed of 4 series strings or less per invertel 3. The total invener capacity has a continuous ac power output 11,440 Watts or less 4 The ac interconnection point is on the load side of service disconnecting means (690.64(B)). 5. One of rhe standard electrical diagrams (El l. El.la. El.lb. or El.lc) can beused to accurately represent the PV system. Interacrive PDF diagrams are available at www.solarabcs.org/permitting.
