EXPEDITED PERMIT PROCESS FOR SMALL.SCALE PV SYSTEMS STANDARD STRING SYSTEM The information in this guideline is intended to help local jurisdict ions and conlraclors identity when PV syslem inslallarions are simple, needing only a basic review and when an installation is more complex. ll is likely that 50%-75% of all residential systems will comply with these simple criteria. For projects that fail to meet the simple crileria. resolulion sleps have been suggested to provide as a path to permit approval Requireil Information fot Perinit : L Site plan showing location of ma]or components on the property. This drawing need not be exactly lo scale, but it should represent relative location oI components at site (see supplied example site plan). PV arrays on dwellings with a 3'perimeter space at ridge and sides may not need seParate nre service review. 2. Electrical diagram showing PV array configuration. wiring system. overcurrenl protection, Invertet disconnecls. required signs, and ac conneclion to building (see suPPlied standard eleclrical diagram). 3 Specihcarion sheers and insralla(ion manuals (if available) lor all manufactured components including. but not limired ro. 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. permitted rcof sructure?

Step 2: Electrical Review o[ PV System (Calculations lor Electrical Diagrar) ln order for a Pv system to be considerâ‚¬d for an expedited permit process, the following must apply: l. PV modules, utiltty-interactive inverters, and combiner boxes are identified For use in PV systems. 2. The PV array rs composed of 4 series strings or less per inverter. l. The toml inverter capacity has a con(inuous ac power outpul 15,440 watts or less 4 The ac interconnection point is on the load side of service disconnecting means (690.64(B)). 5. One ofthe standard electrical diagrams (El. i, El.la, El.lb, or El.lc) can be used to accurately represent the PV system. ln(eractive PDF diagrams are available at www.solarabcs.org/Permirting. Fill out the standard electrical diagram completely. A guide to the electrical diagram is provided to help the applicant understand each blank to fll in. f the electical system is more complex than the standard electrical diagram can elrectively communicote, provide an alternotive diagram with appropriate detail. 2 ExlEDtrED lERMlr PRocEss roR PV sysrEMs c Total Number of Altachment Points 86
