. EXPEDITED PERMIT PROCESS FOR SMALL-SCALE PV SYSTEMS MICRO-INVERTER The information in rhis guideline is intended to help local Jurisdictions and contractors identify when Pv system installations are simple. needing only a basic revierv. and when an installation is more complex. lr is likely that 50%-75% of all residential systems will comply with these simple criteria. For projects that fail to meer the simple criteria, resolution steps have been suggested ro provide as a path to permit approval. Required Infonnatlon fot Pefinit: l. Site plan showing location of ma.jor componen6 on the propeny. This drawing need nor be exacrly ro scale, but it should represenr relarive Iocarion of components at site (see supplied example sire plan). Pv arrays on dwellings with a 5' perimeter space at ridge and sides may not need separate frre service review. 2. Electrical diagram showing PV array confrguration, wiring system, overcurrent protection. inverter. disconnects. required signs. and ac connecrion ro building (see supplied standard electrical diagram). 5, Specihcation sheers and installation manuals (if available) for all manufacrured components including. but not limired to. Pv modules, inverter(s), combiner box, disconnects, and mounting sysrem. Step 1 : Structural Review o[ PV Array Mounting System Is the array to be mounted on a defined, permltted rcof structuref Eres Euo IJ No due to non-comp[iant rooJ or a ground mount, submit compteted worksheet Jor the stntcture wKsl.

Pv modules. utility.interactive inveners, 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 invener capacity has a continuous ac power output 15.440 Wafts or less 4. The ac interconnecrion point is on the load side of service disconnecting means (690.64(8)). 5. Oneofthe standard electrical diagrams (El.1, El.la, El.lb, orEl .lc) can be used to accurarely represent the Pv system. lnteracrive PDF diagrams are available at www.solarabcs.org/permitting. Fill out the standard electrical diagram completety. A gutde to the electrical diagram is provlded to help the applicant understand ea(h blank to ltl in. IJ the electrical system is more complex than the standard electrid diagram can effectively communicate. proride an altemative diagram with appropriate detail. 2 ExpEDrrED PERMIT PRocEss toR PV sysrEMs - MICRo-INVERTER
