EXPEDITED PERMIT PROCESS FOR SMALL-SCALE PV SYSTEMS STANDARD STRING SYSTEM The information in this guideline is intended ro help local jurisdictions and contractors identify when Pv system installations are simple. needing only a basic review and when an inshllation is more complex. It is likely that 50%-75% of all residential systems will comply with these simple criteria. For projects rhat fail ro meet the simple criteria. resolution steps have been suggested to provide as a path to permit approval. Required Inlonnation for Pennit: l. Site plan showing location of major components on the property. This drawing need not be exactly to 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 separate fire service review. 2 Electrical diagram showing PV array connguration, wiring system, overcurrent protection, invertet disconnects, required signs, and ac connection to building (see supplied standard electrical diagram). 3. Specifrcation sheets and insrallation manuals (if available) for all manufactured components including. but not limited to, PV modules, inverter(s), combiner box, disconnects, and mounting system. Step 1 : Structural Review of PV A,,ay Mounting System Is the array to be mounted on a defined, permitted roof structurâ‚¬?ves E no U No due to non-compliant rooJ or a ground mount, submit completed worksheet Jor the struclure WKSI Roof Infotmation: L ls the roohng rype lightweight (Yes = composition. lightweight masonry, metal, etc...)YES lf No. submit completed. worksheetJor rooj structure WKSI (No = heavy masonry, slate. etc...) 2. Does the roof have a single roof coveringZ EVes ! no f No, submit completed worksheetlor rool structure WKSI . 3. Provide method and type of weatherproofing roof penetrations (e.g. flashing, caulk)Flashing, geocell sealant M ount ing Syst em Infonnation : l. Is the mounting structure an en ineered product designed ro nount PV modules with no more than an 18" gap benea(h the module Frames?ves E no IJ No, provide details of structural attachment certiied by a design proJessional. 2. For manufac[ured mounting systems. fill out information on the mounting system below a. Mounting Sy stem Manufacturer ZeP product Name and 64o6"14 Comp Mount Type C b. Total Weigh t of PV Modules sn6 P.2115 '1323 bs c. Total Number of Attachment Points 38 Weight per Attachment Point (b -: c)34.81 lbs (if greater than 45 lbs. see WKS I ) Maximum Spacing Between Attachment Points on a Rail 48 inches (see product manual for maximum spacing allowed based on maximum design wind speed) Total Surface Area of PV Modules (square fee$441 d e f.fr:' Disrribured Weighr of PV Module on Roof (b + l)3.0 Ibs/ft' If distributed weight oI the PV system is grcater than 5 lbs/ft', see WKSr . Step 2: Electrical Review o[ PV System (Calculations for Electrical Diagram) ln order for a PV system to be considered for an expedited permit process, the following must apply: l. PV modules. utility-interactive inverters. and combiner boxes are identifred 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 continuous ac power output 13,44O Watrs or less 4. The ac interconnection point is on the load side of service disconnecting means (690.64(8)). 5. One of the standard electrical diagrams (El.l. El.l a. El.1b. or El.lc) can be used to accurately represent the PV system. lnteractive PDF diagrams are available at wwwsolarabcs.org/permitting. Fill out the standard electrical dtagram completely. A guide to the electrical diagram is provided to help the dpplicant understand each blank to jll in. lf the electrical system is more complex than the standard electical diagram can elfectively communicate, provide an altemative diagram with appropriqte detail. 2 EXIEDI'TED PERMII' PROCTSS TOR PV SYSI'EMS
