. EXPEDITED PERMIT PROCESS FOR SMALL.SCALE I'V SYSTIN45 MICRO_INVERTER The information in rhis guideline is inrended to help local jurisdicrions and conrracrors idenriry when PV system insallations 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. Requireil InJormation for Permit: l. Site plan showing location of ma.;or componenrs on the propeny. This drawing need not be exactly to scale, but r( should represenr relative location of componenrs at sire (see supplied example site plan). Pv arrays on dwellings with a 3 perimerer space at ridge and sides may not need separare hre service review 2. Electrical diagram showing PV array conhguration, wiring sysrem, overcurrent protection, invertet disconnects, required signs, and ac connection to building (see supplied srandard electrical diagram). 3. specificarion sheets and insrallarion manuals (if available) for all manufactured components including. but not Iimired ro. PV modules. inverter(s). combiner box. disconnec(s. and mounting system. Step 1 : Structural Review o[ PV Array Mounting System Is tlre array to be mounled on a dehned, permitted mof structure? EYes ENo IJ No due to non-compbant rooJ or a ground mount, submit completed worhsheet Jor the structure wKS L Roof InJofination: l. Is the roofing rype lighNeight (Yes = composition. lightweight masonry metal, erc. .)Yes If No, submit completed worhsheetlor rooJ structure WKSI (No = heavy masonry, slate, etc...) 2. Does the roof have a single roof covenngi Eyes Eno IJ No, submit completed worhsheetfor roof stucture WKSI. 3. Provide method and rype of wearherproohng roof penetrations (e.9. nashing, caulk)Flashing t I ounting Sy st em I nJo nnation : l. ls the mounting strucure an elgrneered product designed ro mount PV modules with no more ahan an 18" gap beneath the module frames? EJves Euo II No, prwidc details ol structural attachment certiled W a design professional. 2. For manufactured mounting sysrems. hll out information on rhe mounting system below: a Mounting Sysaem Manufacturer SWH Product N ame and Model#Solar Mount b Toral weichr of PV Modules and Rarls 368 lbs c. Total Number of Attachment Pornts 18 d. Weighr per Atrachment Point (b + c)20.44 lbs (if greater than 45 lbs, see WKSI) e. Maximum Spacing Between Attachment Poin(s on a Rail inches (see product manual for maxrmum spacing allowed based on maximum design wind speed) f. Total Surface Area of PV Modules (square feet)141 19 ft2 g. Distribured weight of Pv Module on Roof (b + 0 2.61 lbs/ft'z IJ distributed weght of the Pv ststem is geater than 5 lbstf , see WKSI . Step 2: Electrical Review o[ PV System (Calculations for Electrical Diagram) ln order for a PV s!6tem to be considercd for an expedited permit pocess, the following must apply: l. PV modules, utiliry-interactive inveners, and combiner boxes are identihed for use in PV systems. 2. The Pv array is composed of 4 series strings or less per inverter 3. The total inverrer capacity has a conrinuous ac power output 15,440 watts or less 4. The ac interconnection point is on the load side of service disconnecring means (690.64(8)). 5. One of the sBndard electrical diagrams (E l.l. El.I a, E l lb. or E l.lc) can be used ro accurately represent the PV sysrem. lnteractive PDF diagrams are available ar www solarabcs.org/permifting. I-'ill out the standard electrical diogram completely. A guide to the electrical diagrsm is provided to help the L\)plicdtlt uiderstand each blank to jll in. If the electrical systetn is more conplex than the standard etectrical diagrati ./.tn effecti |t lt cotnmunicqte, provide an alternative diagram with aryropriate detail. 2 EXPEDITED PERMIT I'IIOCESS TOR IV SYSTEMS - MICRO.INVTIU I'IT
