EXPEDITED PERMIT PROCESS FOR SMALL-SCALE PV SYSTEMS <br />STANDARD STRINC SYSTEM <br />The information in this guideline is inrended ro help loczl jurisdictions and contractors identify when PV system insEllations <br />are simple, needing only a basic review and when an insEllation is more complex. It is likely thar 50 % -75 % ot all residential <br />systems will comply wirh these simple criteria. For projects that fail to meet the simple criteria, resolution sreps have been <br />suggested to provide as a path to Permit approval. <br />Requbed Information Jot Pefinit: <br />l. Sire plan showing location of major components on the property. This drawing need nor be exacdy to scale, but it <br />should represent relative location of components at site (see supplied example site plan). PV arrays on dwellings <br />with a 3'perimeter space at ridge and sides may not need separate nre service review. <br />2. Electrical diagram showing PV array conhguration. wiring system, overcurrent protection, inverter, disconnects, <br />required signs. and ac connection to building (see supplied standard electrical diagram). <br />3. Specificalion sheers and installation manuals (if available) for all manufactured components including, but not <br />limited to, PV modules, inverter(s). combiner box. disconnects, and mounting sysrem. <br />Step 1 : Structural Review o[ PV Array Mounting System <br />Is the array to be mounted on a defined, permitted roof structure?

PV modules, urility-interactive inverters, and combiner boxes are identihed for use in PV systems. <br />2. The PV array is composed of 4 series strings or less per inverter. <br />3. The total inverler capacity has a continuous ac power output 13,440 Watts or less <br />4. The ac interconnection point is on the load side ol service disconnecting means (690.64(8)). <br />5. One ofthe smndard electrical diagrams (E L t , E | . I a, E I . 1 b, or E I .

A guide to the electrical diagram is provided to help the applicant <br />understand each btank to lll in. t! the electrical system is more complex thdn the standard electrical diagram can elJectively <br />communicate, provide an alternative diagram with approPriate detail. <br />2 EXPEDITED PERMIT PRocTss FoR PV SYSTEMS <br />f. <br />g
