EXPEDITED PERMIT PROCESS FOR SMALL_SCALE PV SYSTEMS STANDARD 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. lt is likely that 50%-75% of all residenrial systems will comply with these simple criteria. For projec$ that fail to meet the simple criteria, resolution steps have been suglgested to provide as a path to permit approval. Required Inforrn4tion for Pennit: l. Site plan showing location of major components on the property. This drawing need not be exacdy to scale, but it should represent relative location of components at sile (see supplied example site plan). PV arrays on dwellings with a 3'perimeter space at ridge and sides may not need separate fire service review. 2. Electrical diagram showing PV array conf,guration. wiring system, overcurrent protection, invertet disconnects. required signs, and ac connecrion ro building (see supplied srandard elecrrical diagram). 3. Specification sheets and installation manuals (if available) for all manufactured components including, but not Iimited to, PV modules. inverter(s), combiner box, disconnecrs. and mounting system.

Weight per Auachment Point (b. c)j]:l-lbs (if greater than 45 lbs.seeWKSl) e Maximum Spacing Between Atrachment Points on a Rail 48 inches (see producr manual for maximum spacing allowed based on maximum design wind speed) Total Surface Area of PV Modules (square [eet)221 ft'f a Distributed Weight of PV Module on Roof (b + f)3.0 lbs/ftr I distributed wevht oJ the Pv system is greater than 5 lbstf , see WKSI . Step 2: Electrical Review of PV System (Calculations lor Electrical Diagram) In order for a PV system to be considered for an expedited permit prccess, the following mnst apply: l. Pv modules. utility-interactive inverters, and combiner boxes are identihed for use in PV systems. 2. The PV array as composed of 4 series strings or less per inverter. 5. The total inverter capacity has a continuous ac power output 13,440 Watls or less 4. The ac interconnection point is on the load side of service disconnecting means (690.64(8)). 5. One of the s(andard electrical diagrams (E I . 1 , E | . I a, E l I b, or E l I c) can be used to accurately represent the PV system. Interactive PDF diagrams are available at www.solarabcs.org/permining. FilI out the stand.ard. electrical diagram completely. A guide to the electrical diagram is provided to help the applicant understand each blank to fll in. f the electrical system is more complex than the standard electrical diagram can eflectiveu communicate, provide an alternative diagram with appropriste detqil. 2 ExprDrrED PrRMrr PRocrss [oR lv syslEMs
