EXPEDITED PERMIT PRoCESS FoR SMALL-SCALE PV SYSTEMS STANDARD STRINC SYSTEM The information in this guideline is inrended to help local jurisdicrions and contracrors idenrify when pv sysrem installarions are simPle. needing only a basic review and when an installation is more complex. It is tikely thar 50 % -l6x of ^ll residenrial s,stems will comPly with these simple criteria. For projects that fail to meer tlle simple crireria, resolurion steps have been suElgested to provide as a parh to permir approval. Required btfonnation for Perrnit: I Site plan showing location of major components on the property. This drawing need not be exactly ro scale, but it should represent relative location of components at site (see supplied example sire plan) pV arrays on dwellings with a 3'perimeter space at ridge and sides may not need separare nre service review. 2 Electrical diagram showing Pv array conhguration. wiring system, overcurrent protection, inverter, disconnecrs, required signs. and ac connection to building (see supplied srandard elecrrical diagram). 3. SPecihcation sheets and installation manuals (if available) for all manufactured components including, but nor limited to, PV modules. inverter(s), combiner box, disconnects, and mounting system.

Step 2: Electrical Review o[ PV System (Calculations lor Electrical Diagram) In order for a Pv system to be consldered for an expedtted permtt prccess, the followlng must apply: I PV modules, utility-interactive inverters, and combiner boxes are identihed for use in pV systems. 2 The PV array is composed of 4 series strings or less per inverter. 3. The roral inverter capacity has a conrinuous ac power ourpur I J,440 Watts or less 4. The ac interconnection point is on rhe load side of service disconnecring means (690.64(8)). 5. One of the standard electrical diagrams (El.l, EL la. EI.lb, or El.lc) can be used to accurately represenr rhe pV system. lnferactive PDF diagrams are available at www.solarabcs.org/permitting. Fill out the stdndard electrical diagro.m completely. A guide to the etectrical dlagram is provided to hetp the arylicant understand each blank tolll tn.
