IIT } EXPEDITED PERMIT PROCESS FOR SMALL-SCALE PV SYSTENAS . STANDARD STRING SYSTEN^ The informarion in this guideline is inrended ro help local jurisdictions and contractors identify when PV system installations are simple, needing only a basic review and when an insrallation is more complex. It is likely rhat 50 % -7 5% of all residential sysrems 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. Reqaired InJormation for Pefinit: 1. Site plan showing location of major components on the property. This drawing need not be exactly to scale, but it should represent relarive location of componenis aL site (see supplied example site plan). PV arrays on dwellings with a 5'perimeter space ar ridge and sides may not need separate fire service review. 2. Elecrrical diagram showing PV array conhguration, wiring sysrem, overcurrenr prorecrion. inverter, disconnecrs, required signs. and ac connection to building (see supplied standard electrical diagram). 3. Specification sheers and installation manuals (if available) for all manulactured components including. but not limited to, PV modules, inverrer(s), combiner box. disconnects, and mounting system. Step 1: Structural Review of PV Array Mounting System Is the array to be mounted on a defined, permitted roof structure?ves E no U No due to non-compliant rooJ or a ground mount, submit completed worksheet lor the structure wKSl Roof InJonnation: CON,IP SHINGLEl Is the roofing rype lightweight (Yes = composition, lighrweight masonry, metal, etc...)

Step 9: Electrical Review o[ 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, utiliry-inreractive 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. 3. The rotal inverter capacity has a continuous ac power output 13.440 Watrs or less 4. The ac interconnection point is on rhe load side of service disconnecting means (690.64(B)). 5. One of the srandard electrical diagrams (E1.1, El.la, E l.lb, or El.lc) can be used to accurately represenr the PV system. lnteracrive PDF diagrams are available at www.solarabcs.org/permitting. Fill out the standard electrical diagrum completely. A guide to the electrical diagram is provided to help the appltcant understand each blank to rtll in. IJ the electrical system is more complex than the standard electr'lcal dtagram can elrectively communicate, provide an alternative diagram Nith approprlate detail. 2 Exp[DrrED PERMTT PRocESs FoR PV Sysrr,Ms
