Pon+<la s(AfiuaL( <br />EXPEDITED PTRMIT PROCESS FOR SMALL-SCALE PV SYSTEMS <br />MICRo-INVERTER <br />The informauon in this guideline is intended to help loca.l jurisdictions and contractors identity when PV sysrem insBllarions <br />are simple, needing only a basic review and when an insra.llation is more complex. It is likely that 50 %-75 % of all residential <br />sysEms will compty wirh these simple criteria. For projects rhat fail ro meet the simple criteria, resolution sreps have been <br />suggested !o provide as a pati to permil approval. <br />Required Infonnation Jor Peflnit: <br />l. Sire plan showing location of major components on rhe property. This drawing need not be exacrly to scale, but it <br />should represenr relative locarion of components at site (see supplied example site plan). PV arrays on dwellings <br />with a 3'perimeter space at ridge and sides may not need separate nre service review. <br />2. Electrical diagram showing Pv array confrguration, wiring system, overcurrent protec on, inverter, disconnecB. <br />required signs, and ac connection to building (see supplied standard electrical diagram). <br />3. Specifrcaion sheeG and insallation manuals (if available) for all manufactured componenrs lncluding, but not <br />limited to, PV modules, inverter(s), combiner box, disconnects, and mounting system. <br />Step 1 : Structural Review o[ PV Array Mounting System <br />ts tlre array to be mounted on a defined, permitted roof structure t N"" Eno <br />IJ No due to non-compliant rooJ or a ground mount. submit completed w6rhsheet Jor the srructure WKSI . <br />Roof InJormation: <br />(Yes = com osition, I ighrweight masonry, melal, erc. .)t+ rr)r <br />Il No,rool strucfire I (No = heavy masonry, slate, etc.. .) <br />En"2.

PV modules, utility-interactive inverters, and combiner boxes are identifled for use in PV systems. <br />2. The Pv array is composed of 4 series strings or less per inverter. <br />3. The total inverter capaciry has a continuous ac power output 15,440 Watts or less <br />4. The ac interconnection point is on rhe load side of service disconnecting means (690.64(8)). <br />5.
