{ EXPTDITEO PERMIT PNOCESS FOR SUNII-SCALE PV SYSTTUS SIRNoRno SrRrNc Sysre pr The information in this guideline is intended to help localjurisdictions and contractors identify when PV system installations are simple, needing only a basic review and when an installation is more complex. It is likely that 50%-75% of all residential systems will comply with these simple criteria. For projects that fail to meet the simple criteria, resolution steps have been suggested to provide as a path to permit approval. Re quire d Information for Permit : 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 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 configuration, wiring system, overcurrent protection, inverter, disconnects, required signs, and ac connection to building (see supplied standard electrical diagram). 3. Specifrcacion sheets and installation 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 Array Mounting System Is the array to be mounted on a dehned, permitted roof structuret Eyes Er.lo IJ No due to non-compliant roof or a ground mount, submit completed worksheet Jor the stucture WKSI. Roof Information: l. ls the roofing type lightweight (Yes = composition, lightweight masonry, metal, etc.) Composition Shingles I If No,submitcompletedworksheetJorroof structureWKS| (No = heovymasonry,slate,etc...). 2. Does the roof have a single roof coveringz Elves E uo If No, submit completed worksheetJor roof structure WKSI . 3. Provide method and type of weatherproofing roof penetrations (e.9. flashing. caulk)Flashing M ounting Sy stem Information : 1 . Is the rnounting structure an beneath the module frarnes? Name and Model# SNAPNRACK ULTRA "ffil"."E1ljoduct designed to mount PV modules with no more than an 18" gap If No, provide details of structural attachment certified by a design professional. 2. For manufactured mounting systems, fill out information on the mounting system below: a. Mounting Systern Manufacturer SNAPNRACK Product b. Total Weight of PV Modules an{d Rails 1387 165 c. Total Number of Attachment Points 4 d. Weight per Attachment Point (b *346 s (if greater than 45 lbs, see WKS I ) e. Maximum Spacing Between Attachment Points on a Rail 24 inches (see product manual for maximum spacing allowed based on maximum design wind speed) f. Total Surface Area of PV Modules (square feeQ 544'16 Jrz g Distributed Weight of PV Module on Roof (b +2.5 lbs/ft2 If distributed weight of the PV system is greater than 5 lbslfP, 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 process, the following must apply: l. 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 continuous ac power output 13,44O Watts or less 4. The ac interconnection point is on the load side of service disconnecting means (690.64(B)). 5. One of the standard electricaldiagrams (E1.1, El.la, El.1b, or El.lc) can be used to accurately represent the PV system. Interactive PDF diagrams are available at www.solarabcs.org/permitting. Fill out the standard electrical diagram cornpletely. A guide to the electrical diagram is provided to help the applicant understand each blank to fill in. If the electrical system is more complex than the standard electrical diagram can efJectively communico,te, provide an alternative diagram with appropriate detail. 2 EXI,EDITED PERMIT PROCESS FOII.
