EXPEDITED PERMIT.PROCESS FOR SMALL-SCALE PV SYSTEMS STANDARD STRING SYSTEM 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 5O%-75% of all residential systems will comply with these simple criteria. For projecm that Fail to meet the simple criteria, resolution steps have been suggested to provide as a path to permit approval. Required h{ormation Jor Permit: 1. Site plan showing location of major components on the property. This drawing need nor be exactly ro scale, but ir should represent relative location of components at site (see supplied example site plan). PV arrays on dwellings with a 3'perimeter space at ridge and sides may not need separate nre service review 2. Electrical diagram showing PV array conflguration, wiring system. overcurrent protection. invertet disconnects, required signs, and ac connection to building (see supplied sEndard electrical diagram). 5. Specincation sheets and installation manuals (if available) for all manufactured components including, but not limited to, PV modules, inverter(s), combiner box, disconnects, and mounting system. Step 1 : Structural Review o[ PV Array Mounting System Is the aray to be mounted on a defined, permittrd roof structurâ‚¬?Yes ENo U No due to non-compliant roof or a ground mount, stbmit completed worksheet for the structure WKSI Roof Infonnation: 1. Is the roofrng type lighMeight (Yes = composition, lightweight masonry, meral, erc...)YES It weighs over 9lbs If No, submit completed worksheet lor rool stn)cture WXSI fNo = heavy masonry, slate, etc. . .) 2. Does the roof have a single roof covering? Eyes ntlo U No, submit completed worksheet fot roof stn)cture WNSI . 3. Provide method and type of weatherproofing roof penetrations (e.g. flashing, caulk)Caulk, Flashings M ountifi g Sy s t ern Inf orm at ion : 1. Is the mounting structure an benearh the module frames? ineered product designed to mount PV modules with no more than an 18'' gape Yes tr No Mounting Sys rem Manufacturer UNIMC producr Name and p1s6.1g SOLARHOOK UNIV 004CT5S Total Weigh t of PV Modules un6 nu1lt 1535.75 lbs Total Number of Atnchment Points 79 Weight per Attachment Point (b + c)19.43 bs (if greater than 45 lbs, see WKS I ) Maximum Spacing Berween Atrachmen!

Distributed Weighr of PV Module on Roof (b + l)3.22 lbs/[t'z Il distributed wâ‚¬ight oI the PV system is geater than 5 lbslft'z, see WRSI . Step 2: Electrical Review of PV System (Calculations lor Electrical Diagram) In order for a PV system to be considered for an expedited permit process, the following must apply: l. 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 output 13,440 WatB or less 4. The ac interconnection point is on the load side of service disconnecting means (690.64(8)). 5. One ofthe standard electrical diagrams(81.1, E1.1a, El.1b, orEl.1c) can be used to accurately represent rhe PV system. Interactive PDF diagrams are available at www.solarabcs.org/permitting. Fill out the standard. electrical diagram completely. A guide to the electical diagram is Wovided. to help the aryticant understand each blank to ftt in. If the electrica[ system is more complex than the standard electrical diagram can elJectively communicate, provide an alternative diagram with approprio.te detail. 2 ExpEDITED PERMIT PRocEss FoR PV SysrEMs a. b.
