EXPEDITED PERMIT PROCESS FOR SMALL-SCALE PV SYSTEMS MICRo-INVERTER The informalion in this guideline is intended to help localjurisdic ons and conrracbrs identify when pv sysrem insallarions are simPle, needing only a basic re1,iew, and when an installadon is more complex. tt is likely rhar 50 % -75 % of all residenrial systems will comply wirh lhese simple criteria. For projecrs rhat fail o meer rhe simple criteria, resolution sreps have been suggested ro provide as a parh ro permir approval. Required Infonnation for Permit: l. Site plan showing location of major components on the properry. This drawing need not be exacrly ro scale, bur ir should represent rclative location of components ar site (see supplied example si!e plan). Pv arrays on dwellings with a 3' perimeter space ar ridge and sides may nor need separate hre service review. 2. Electrical diagram showing PV array conhguration, wiring system. overcurrent protection, inverre( disconnects, required signs, and ac connecrion ro building (see supplied standard elecrrical diagram). 3. Specincation sheets and installation manuals (if available) for all manufactured components including, bur nor limited to, PV modules, invener(s), combiner box. disconnec6, and mounting system. Step 1 : Structural Review of PV Array Mounting System Is the aray to be mounted on a defrned, permltted rcof srructurc? Ey.s EIno lf No due to non-compliant roof or a ground mount. submit completed worhsheet Jor the structJre WKSI . Roof Injonnation: l. Is the roofing rype lighrweighr (Yes = composirion, Iighrweighr masonry metal. erc ..)Yes 3. Provide method and rype of weatherproohng roof penerrarions (e.9. flashing. caulk)Flashing M ounting Syst ern Infonnat ion : l. Is the mounting srructure an benearh the module frames? e neered product desi gned to mount PV modules with no more rhan an I8" gap Yes No IJ No, prwide detaik of structural attachmmt certiled by a design proJessional. 2. For manufacrured mounting sysrems, hll out information on the mounting sysrem below a. Mounting Sysrem Manufacturer SWH product Name and 1,t4o6"1x Solar Mount b. Toral Weight of PV Modules and Rails 't478.40 bs c. Total Number of Attachment Poinrs 66 d. Weight per Attachmenr Poinr (b + c) 22.40 bs (if greater than 45 lbs. see WKSI ) e. Maximum spacing Berween Atachment Points on a Rail 72 inches (see producr manual for maximum spacing allowed based on maximum design 563.77 wind speed) f. Tolal Surface Area of Pv Modules (square feet) g. Distribured Weighr of PV Module on Roof (b + f)2.62 lbs/fF Il dis*ibuted weight of the PV system is geater than 5 lbsttr, see WKSI . Step 2: Electrical Review o[ PV System (Calculations for Electrical Diagram) In order for a PV system to be considered for an expedited permit pmcess, the following must apply: l. PV modules, urilily-inreractive inverters, and combiner boxes are idenrihed for use in PV systems. 2. The PV array is composed of 4 series strings or less per invener 5. The roral inverter capacity has a continuous ac power output 13,440 Watts or less 4. The ac interconnecrion poinr is on the load side of service disconnecring means (690.64(8)). 5. one of the sandard elecrrical diagrams (E I . I . E L I a, E I . I b, or E ]. I c) can be used ro accurarely represent rhe pV system. Interactive PDF diagrams are available al wwwsolarabcs.org/permitting. Fill out the stondard electrical diagram completely. A guide to the electical diagram is prottided. to help the applicant understand each bllnk to lll in. Il the electrical system is morc complex than the standard electrical diagran can efJectiveb, communicate, provide an alterfiative diagram with awropriate detail. 2 rxpEDrrED PERMIT pRocEss FoR pv SysrEMs - MrcRo-INVERTER IJ No, submit completed worlrsheetJot rooJ structure WKSI (No = heavy masonry, slate, etc.. .). 2 Does rhe roof have a single roof coveringz Elyes Effo IJ No, submit completed worksheetlor rcoJ structure WKSI .
