EXPEDITED PERJVTIT PROCESS FOR SMALL-SCALE PV SYSTEMS. STANDARD STRING 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 installation 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 crileria, resolution s[eps have been suggested to provide as a path to permit approval. Requireil Inlonnation Jor Pet'mit : t. Site plan showing location of major components on the property. This drawing need not be exacdy to scale, but it should represent relative locarion 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 separale fire service review. 2 Electrical diagram showing PV array configuration, wiring system, overcurrent protecrion, inverter, disconnects, required signs, and ac connection to building (see supplied standard electrical diagram). 3. Specification sheers and installation manuals (if available) for all manuFactured componenrs including, but not limited ro, PV modules. inverter(s), combiner box. disconnects, and mounting system.

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 following must apply: l. PV modules, utility-interacrive inverters, and combiner boxes are identiEed for use in PV systems. 2. The PV array is composed of 4 series strings or less per inverter 3. The total inverter capacity has a conrinuous ac power output 13,440 WaIts or less 4. The ac interconnection point is on the load side of service disconnecting means (690.64(8)). 5. One of the standard electrical diagrams (El.l. El.la, El.lb, or El.lc) can be used to accurately represent the PV system. lnteractive PDF diagrams are available at www.solarabcs.org/permifting. Fill out the standard electical diagram completely. A guide to the electrical diegram is provided to help the applicsnt understand eqch blsnk to jll in. If the electrical system is more complex than the standard electical diagram con efJectively communicate, provide an alternative diagram with awropritte detail. 2 ExpEDtrED PERM|T PRocEss FoR PV SysrEMS
