EXPEDITED PERMIT PROCESS FOR SMALL-SCALE PV SYSTEMS STANDARD STRING SYSTEM The informarion in rhis guideline is intended to help Iocal jurisdictions and contractors identify when PV system inslallations are simple, needing only a basic review and when an installation is more complex. It 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 suggesred to provide as a path to permit approval. Reqtireil InJonnation for P*mit: 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 3'perimeter space at ridge and sides may not need separate hre service review. 2. Elecfttcal diagram showing PV array configuration, wiring system, overcurrent protection, inverter, disconnecls, required signs, and ac connec[ion to building (see supplied standard electrical diagram). 3. Specihcation sheets and installation manuals (if available) for all manufaclured components including, but not limited ro, PV modules, inverter(s), combiner box, disconnects, and mounring system.

Step 2: Electrical Review o[ PV System (Calculations lor Electrical Diagtam) In order for a Pv system to be considered for an expedited permit process, the following must apply: t. pV modules, utility-interactive inverters, and combiner boxes are identified for use in PV systems. 2. The PV array is composed of 4 series strings or less per inverter 5. The total inverter capacity has a continuous ac power output I 3,440 Watts or less 4. The ac interconnection point is on the load side of service disconnecting means (690.64(8). 5. One of rhe standard etecrrical diagrams (E I . I , E L I a, E 1 . 1 b, or E I . I c) can be used to accurately represent the PV system. Interactive PDF diagrams are available at www.solarabcs.org/permitting. Fill out the standard electrical diagram completely. A guide to the electrical diagram is provided to help the apPlicant understand each blank to lll in. IJ the electrical system is more complex than the standard electical diagram can elJectively communicate, provide an alternatite diagram with apProPriate detail. 2 EXPEDITED PERMIT PROCESS FOR PV SY5TEMS COMP SHINGLE fr'?
