EXPEDITED PERMIT PROCESS FOR SMALL-SCALE PV SYSTEMS STANDARD STRINC SYSTEM The information in this guideline is intended to help local jurisdictions and contractors identify when PV system installations are simple, needing only a basic review and when an insEllation is more complex. lt 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 suggesled to provide as a path to permir approval. Required Infornation for Pennit: 1. 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 3'perimeter space at ridge and sides may not need separate nre service review. 2. Electrical diagram showing PV array confrguration, wiring system, overcurrent protection, invertet disconnects, required signs, and ac connection to building (see supplied standard electrical diagram). 3 Specification sheets and installation manuals (if available) for all manufactured componenm including, but not limited to, PV modules, inverter(s), combiner box, disconnects, and mounting system. Step 1 : Structural Review o[ PV Array Mounting System Is the array to be mounted on a defined, permitted rcof structure?

Step 2: Electrical Review o[ PV System (Calculations for Electrical Diagram) tn order for a Pv s]Etem to be consider€d for an expedited permit process, the following must apply: 1. PV modules, utility-interacrive inverters, and combiner boxes are identihed for use in PV systems. 2. The PV array is composed of 4 series strings or less per inverter. 3. The toml inverter capacity has a continuous ac power output 13,440 Watts or less 4. The ac inrerconnec[ion point is on the load side of service disconnecting means (690.64(8)). 5. One of rhe srandard elecrrical diagrams(El.l,El.la,El.lb,orE1.lc)canbeusedtoaccuratelyrepresentthePV system. lnteractive PDF diagrams are available at www.solarabcs.org/permitting. Fill out the standard electical diagram compleiety. A guide to the electrical diagram is provid.ed to help the appltcant understand each blank to ltl in.
