EXPEDITED PERTTzIIT PROCESS FOR SITnEII-SCALE PV SYSTEMS STnNDARD STRINC SyslrpI The information in this guideline is intended to help local jurisdictions 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 quired Information for Permit : I . Site plan showing location of major components on the property. This drawing need not be exactly to scale, but it should represent relative location oi components at site (see supplied example site plan). PV arrays on dwellings with a 5' perimeter space at rid$e and sides may not need separate fire service review. 2. Electrical diagram showing PV array configuration, wirin$ system, overcurrent protection, inverter, disconnects, required signs, and ac connection to building (see supplied standard electrical diagram). 3. Specification sheets and installation manuals (il 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 defined, permitted roof structuret Elyes Eno IJ No due to non-compliant rooJ or a ground mount, submit completed worksheetJor the structure WKSI. Roof Information: l. Is the roofing type lightweight (Yes : composition, lightweight masonry, metal, etc YES If No,submitcompletedworksheetforroof structureWKS( (No = heavymasonry,slate,etc...). 2. Does the roof have a single roof coveringZ Eyes ! no If No, submit completed worksheet.for roof structure WKSI . 3. Provide method and type of weatherproohng roof penetrations (e.g. flashing, caulk)Flashing, geocell sealant M ounting Sy stem Information : I . Is the mounting structure an elgineered product designed to mount PV modules with no more than an 18" gap beneath the module frames? Ll yes Ll tlo $ No, provide details of structural attachment certirfied by a design professional. 2. For manufactured mounting systems, frll out information on the mounting system below: a. Mountind Svstem Manuflacturer Zep Procluct Name ancl Moclel# comp Mount Type c b. Total Weigh t of PV Modules and Rails 569 lbs c. Total Number of Attachment Poin tc 51 d. Weight per Attachment Point (b+c) 11.16 lbs (if greater than 45 lbs, see WKSI) 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 leet)472 tr' g Distributed Weight oF PV Module on Roof tO + f\ 1-2 lbs/[t2 If distributed weight of the PV system is greater than 5 lbslft2, see WKSI. Step 2: Electrical Review of PV System (Calculations for Electrical Diagram) In order for a PV system to be considered for an expedited permit process, the followingl must apply: I. 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 outpuL 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 electrical diagrams (El.l, El.la, El.lb, 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 completely. A guide to the electrical diagram is provided to help the applicant understand each blank tofill in. If the electrical system is more complex than the standard electrical diagram can effectively communicate, provide an alternative diagram with appropriate detail. 2 Exl,EDtrED l,ERMlr pRocESs FoR pv sysrEMS
