EXPEDITED PERMIT PNOCTSS FOR SITZTNII-SCALE PV SYSTEMS <br />SrnNoRRo SrruNc Sysrrpt <br />The information in this guideline is intended to help localjurisdictions and contractors identify when PV system installations <br />are simple, needing only a basic review and when an installation is more complex. It is likely rhat 50%-75 % of all residential <br />systems will comply with these simple criteria. For projects that fail to meet the simple criteria, resolution steps have been <br />suggested to provide as a path to permit approval. <br />Re quire d Informatiott for Permit : <br />l. Site plan showing location of major components on the property. This drawing need not be exactly to scale, but it <br />should represent relative location of components at site (see supplied example site plan). PV arrays on dwellings <br />with a 3'perimeter space at ridge and sides may not need separate frre service review <br />2. Elecrrical diagram showing PV array conhguration, wiring system, overcurrent protection, inverter, disconnects, <br />required signs, and ac connection to building (see supplied standard electrical diagram). <br />3. Specifrcation sheets and installation manuals (if available) for all manufactured components including, but not <br />limited to, PV modules, inverter(s), combiner box, disconnects, and mounting system. <br />Step 'l : Structural Review of PV Array Mounting System <br />Is the array to be mounted on a defined, permitted roof structuref Eyes Ef,lo <br />IJ No due to non-compliant roof or a ground mount, submit completedworh,sheetfor the structure WKSI. <br />Roof Infoxmation: <br />l. Is the roofing type lightweight (Yes = composition, lighrweight masonry, metal,erc. )Yes = composition shingle <br />If No,submitcompletedworksheetforroof strttctureWRSI (No = heavymasonry,slate,etc...). <br />2. Does the roof have a single roof coveringz EIves !no <br />If No, submit completed worh"sheet for roof structure WKEI . <br />3. Provide method and type of weatherproohng roof penetrations (e.9. flashing, caulk). flashing <br />Mounting Sy stern Informatiqn : <br />I . Is the mounting structure an <br />beneath the module frames?"ffil"r"EX,ijoduct designed to mount PV modules with no more than an 18" $ap <br />If No, prwide detaib of strucfiral attachment certified by a design professional. <br />2. For manufactured mounting systems, fill out information on the mounting system below: <br />a. Mounting System Manufacture. Unirac Product Name and Model#SM Light rail 168" mill (Model# - 315168M), <br />b. Total Weight of PV Modules and Rails 653.64 lhc FLASHKIT PRO, MILL 1OPK (Model # - 004055M) <br />c. Total Number of Attachment Points22 <br />d. Wei(ht per Attachment Point (b + g130'5 lbs (if greater than 45 lbs, see WKSI ) <br />e. Maximum Spacing Between Attachment Points on a Rail 72 inches (see product manual for <br />maximum spacing allowed based on maximum design wind speed) <br />f. Total Surface Area of PV Modules (square feet)254.93 ftz <br />g Distributed Weight of PV Module on Roof tU + fl 2.49 lbs/ft2 <br />If distributed weight of the PV system is greater than 5 lbslff, see WKSI. <br />Step 2: Electrical Review of PV System (Calculations for Electrical Diagram) <br />In order for a PV system to be considered for an expedited permit process, the following must apply: <br />I. PV modules, utility-interactive inverters, and combiner boxes are idenrified for use in PV systems. <br />2. The PV array is composed of 4 series strings or less per inverter. <br />3. The total inverter capacity has a continuous ac power output 13,440 Watts or less <br />4. The ac interconnection point is on the load side of service disconnecting means (690.64(8)). <br />5. One of the standard electricaldiagrams (El.l, El.la, El.lb, or El.lc) can be used to accurately represent the PV <br />system. Interactive PDF diagrams are available at www.solarabcs.org/permitting. <br />Fill out the standard electrical diagram completely. A guide to the electrical diagram is provided to help the applicant <br />understand each blank tofill in. If the electrical system is more complex than the standard electrical diagram can effectively <br />communicate, provide an alternative diagram with appropriate detail. <br />2 Expe orre o PERMIT PRocEss FoR PV SysrEMS
