EXPEDITED PERMIT PROCESS FOR SMALL_SCALE PV SYSTEMS SIANDARD STRING SYSTEM The information in this guideline is inrended to help local jurisdictions and contractors identify when PV system installations are simple, needing only a basic review and when an installation is more complex. Ir is likety rhat 50%-75% of all residential systems will comply with lhese simple criteria. For projects that fail to meet the simple criteria, resolution steps have been suggested to provide as a path to permit approval. Required Inforrnation Jor Permit: 1. Site plan showing location of major componenrs on the property. This drawing need not be exactly to scale, but it should represent relative location of components at siLe (see supplied example site plan). PV arrays on dwellings with a 5' perimeter space at ridge and sides may not need separate hre service review. 2. Electrical diagram showing PV array connguration, wiring system, overcurrenr protection, inverter, disconnects, required signs, and ac connection to building (see supplied srandard elecrrical diagram) 3. Specifrcation sheets and installarion manuals (if available) for all manufactured components including, bur nor limiled rc, PV modules. inverter(s), combiner box, disconnects, and mounting system.

Step 2: Electrical Review o[ PV System (Calculations for Electrical Diagram) In order for a Pv system to be considercd for an expedited permit process, the following must apply: t. PV modules, utility-interactive 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 total inverter capacity has a conLinuous ac power output 13,440 Wat6 or less 4. The ac interconnection point is on the load side of service disconnecting means (690.64(8)). 5. One of the standard elecrrical diagrams (E l I , E l I a, E I I b, or E 1 . I c) can be used to accurately represent the PV sysrem. Interactive PDF diagrams are available at www.solarabcs.org/permirting FiLL out the standard electical diagram completely. A guide to the elecfficat diagram is provid.ed to help the applicant understand each blanh to ill in. If the electricql system is more complex than the standard electricsl diagram can e.ffectiyely communicote, provide an altematiye diagram with sppropriate detail. 2 txprDlltD pERMtr pRocESs FoR I,v sysrEMS
