EXPEDITED PERIVTIT PROCESS FOR SMALL-SCEIE PV SYSTEMS STANDARD STRING SYSTEM The informarion in this guideline is inrended to help local jurisdictions and contractors identify when PV system installations are simpJe, needing only a basic review and when an installation is more complex. lt is likely that 5O%-75% of all residential sysrems will comply with these simple criteria. For projects thal fail to meet the simple criteria, resoludon steps have been suggested to provide as a path to permit approval. Reguireil Information for Permit: 1. Site plan showing location of major components on the property. This drawing need not be exactly to scale, but it should represent relarive ]ocation 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. Electrical diagram showing PV array connguration, wiring sysrem. overcurrent protecrion. Inverter, disconnects, required signs, and ac connection to building (see supplied snndard electrical diagram). j. Specification sheers and installarion manuals (if available) for all manufaclured componenrs including, but not Iimited to, PV modules, inverLer(s), combiner box. disconnects, and mounting sysrem.

The PV array is composed of 4 series strings or less per inverter. 3. The toral inverter capacity has a continuous ac power output l3'440 Watrs or less 4. The ac inlerconnection point is on the load side of service disconnecting means (690.64(8)). 5. One of rhe srandard electrical diagrams (81.1 , E l.la, E1.1b, or El.lc) can be used to accurately represent the PV system. Inleractive PDF diagrams are available at wwwsolarabcs.org/permitting.
