EXPEDITED PERMIT PROCESS FOR SMALL-SCALE PV SYSTEMS MICRO-INVERTER The informarion in this guideline is intended to help local jurisdictions and contractors identiS./ when PV system installations are simple, needing only a basic revieq 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 suggesrcd to provide as a path to permit approval. Required InJormation for Pennit: 1. Site plan showing location of major componenls on the property. This drawing need not be exactly to scale, but it should represent relative locarion of components at site (see supplied example site plan). Pv afiays on dwellings with a 5'perimeter space at ridge and sides may not need separarc fire service review. 2. Electrical diagram showing PV array configuradon, wiring sysrem, overcurrent protection, inverter, disconnects, required signs, and ac connection to building (see supplied standard electrical diagram). 3. Specincarion shee6 and insnllation manuals (if available) [or all manufactured components including, but not limited to, PV modules, inverter(s), combiner box, disconnects, and mounting system. Step 1 : Structural Review of PV Anay Mounting System Is the aray to be mountâ‚¬d on a dehned, permittâ‚¬d roof structurâ‚¬? Ev"t nn" I No due to non-compliant rool or a ground mount, submit completed worhsheetJor the strucd]re WKSI. Roof Injonnation: 1. Is the roonng rype lightweighr Ges = composition, lighMeight masonry metal, etc...)Yes = Composition lf No, submit completed worksheet for roof sffucture WKSI (No = h 2. Does the roof have a single roof covering? pYes !no IJ No, bmit completed worhsheet for roof stracture WKSI. 3. Provide method and rype of weatherproofing roof penetrat M ount in g Sy st em I nfo rmation : ea'ty masonry, slate, etc . . .) ions (e.9. flashing. caulk)f lashing, caulking L Is the mounting srructure an glgineered product desrgned ro mount PV modules with no more than an 18" gap benearh the module frames? B[Yes I t,to If No, provide detail.s ol strucaral attachment cerdrted by a design proiessionat. 2. For manufactured mounting systems, fill out informa tion on the mounting syst em below a. Mounting Sysrem Manufacturer lronRidge uct Name and Model#Flash Fool b. Total Weig ht of PV Modules and Rails lbs c. Total Number of Attachment Points d. Weight per Attachment Point (b + c b s (if 72 greater than 45 lbs. see wKSl ) e. Maximum Spacing Between Attachment Points on a Rail inches (see product manual for maximum spacing allowed based on maximum desi gn wind speed) f. Total Surface Area of Pv Modules (square feeo 252 g. Distributed Weight of PV Module on Roof (b +2.47 lbs/frl Il distributed weight of the w system is geater than 5 lbslff , see wKSl. Step 2: Electrical Review o[ PV System (Calculations lor Electrical Diagram) In order for a Pv systâ‚¬m to be considercd for an exPâ‚¬dited permit process, the following must aPply: l. PV modules, utility-interacrive inverrers, 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 13,440 Watts or less 4. The ac interconnection point is on the load side of service disconnecting means (690.64(8)). 5. One of rhe standard electrical diagrams (El.l, El.l a, El.lb, or El.1c) can be used to accurately represent the PV system. Interactive PDF diagrams are availabie at www.solarabcs.org/permitting. Fitt out the standard electrical diagram completely. A guide to the electrical diagram is provided to help the arylicant understand each blank to jll in. Il the electrical system is more complq than the standard electrical diLgram can elJectiveu communicate, provide qn alternative diagram with awropriate detqil. 2 ExpEDtrED PEp.N4rr PRocESs FoR PV SYSTEMS - MIcRo-INVERTER
