EXPEDITED PERMIT PROCESS FOR SMALL-SCALE PV SYSTEMS STANDARD STRINC SYSTEM The information in this guideline is intended to help local jurisdictions and conrractors identify when PV system installations are simple, needing only a basic review, and when an installation is more complex. Ir is likely that 50%-75% of all residential 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 path to permit approval. Required Information for Permit: L Site plan showing location of major components on the property This drawing need not 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 f'perimeter space at ridge and sides may not need separate fire service review. 2. Electrical diagram showing PV array conhguration, wiring system. overcurrent prorection, inverter, disconnecrs, required signs, and ac connection to building (see supplied standard electrical diagram). 3. Specification sheets and installation manuals (if available) for all manufactured components including, but nor limited ro, PV modules, inverter(s), combiner box, disconnecrs, and mounring sysrem.

Step 2: Electrical Review of PV System (Calculations for Electrical Diagram) In order for a PV system to be considered for an expedited permit process, the followinE must apply: L PV modules, utility-interactive inverters, and combiner boxes are identifred for use in PV systems. 2. The PV array is composed of 4 series strings or less per inverter. 3.
