. EXPEDITED PERMIT PROCESS FOR SNAALL-SCALE PV SYSTENAS MICRO-INVERTER The informarion in rhis guideline is intended ro help local jurisdictions and contractors identify when PV system installations are simple. needing only a basic review and when an insEllation is more complex. It is likely that 50%-75% of all residential sysrems will comply wirh rhese simple crireria. For projects that fail to meet the simple criteria. resolution steps have been suggested to provide as a path to permit approva!. Requireil Information fot Perfiit: 1. Sire plan showing locarion of major componenrs on the property. This drawing need not be exactly to scale, but it should represent relarive location of componenrs ar site (see supplied example site plan). PV arrays on dwellings with a 3' perimeter space at ridge and sides may not need separate fire service review. 2. Electrical diagram showing PV array configuration. wiring system, overcurrent protection. inverter, disconnecrs, required signs, and ac connection to building (see supplied standard electrical diagram). 3. Specifrcarion 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 Nulounting System Is the array to be mounted on a defined, permitted roof structure?ves n No U No due to non-compliant rooJ or a ground mount, submit completed worksheet Jor the structure wKSl Roof Inforfiation: COI,4P,SHINGLE1. ls rhe roofing type lightweight (Yes = composition, lightweighl masonry, metal, elc...) lj No, submit completed worksheet jor rooJ structure WfiSl (No = hel.vy masonry, slate, etc...) ves Er,lo IJ No, submit completed worksheetJor rooJ structurc WNSI 2. Does the roof have a single rooF covering? FLASHING Y CAULK ineered product designed to mounr PV modules with no rnore than an 18" gap OUICK I\4OUNT 3.

For manufactured mounting systems, fill out information on the mounting system below roduct Name and Mode 1g CLASSIC COMPOSITION MOUNIa. N4ounting System Manufacturer b. Toral Weighr c Total Number of Attachment Poinrs 26 f. Total Surlace Area of PV Modules (square feet) g. Distributed Weight of PV N4odule on Roof (b : D of pV N4odules nn6 no11r 1,159.6 lbs d. Weighr per Attachment Point (b + c) 44 6 lbs (if greater than 45 lbs. see wKSl ) e. Maximum Spacing Between Attachment Points on a Rait 72 inches (see producl manual for maximum spacing allowed based on maximum design wind speed) 677 fi'? 1 .71 IJ distributed weight of the Pv system is greater than 5 lbstt'1, see wRSl . Step 2: Electrical Review o[ PV System (Calculations lor Electrical Diagram) In order for a Pv system to be considered for an expedited permit process, the foltowing must apply: t. PV modules, utility-inreractive invefters. and combiner boxes are identihed for use in PV systems. 2. The PV array is composed o[ 4 series slrings 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 ol the srandard electrical diagrams (81.1. E l.la, E l.lb, or El.lc) can be used to accurately represenr the PV system. Interactive PDF diagrams are available at www.solarabcs.org/permitting. Fill out the standard electrical diagram comptetely. A guide to the electrical diagram is ptovided to help the applicant underctand each blank to frll in. IJ the electrical system is more complex than tlrc standard electrical diagram can ejfectively communicate, provide an alternative diagram with appropriate detail. 2 EXPI]DITIJD PERMIT PROCESS FOR PV SYSTEMS - MICRO-INVERTER lbs/fu1
