EXPEDITED PERMIT PROCESS FOR SMALL-SCALE PV SYSTEMS M ICI{O- INVE RTER The information in this guideline is intended to help local jurisd icrions and contracrors idenrify when PV sysrem insrallarions are simple. needing only a basic review. and when an installation is more complex. lt is likely thar 50%-75% of all residenrial 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. Required InJormation fot Pennit: ) Sile plan showing location of major componenrs on rhe property. This drawing need nor be exacrly ro scale, bur it should represent relative location of components at site (see supplied example site plan). PV arrays on dwellings wirh a 3'perimeter space ar ridge and sides may not need separate hre service review. Electrical diagram showing PV array conflguration, wiring system, overcurrent protection, inverter, disconnecrs. required signs. and ac connecrion ro building (see supplied srandard elecrrical diagram). Specification sheets and installation manuals (if available) for all manufactured componenrs including, bur nor limited to, PV modules, inverter(s), combiner box. disconnects. and mounting system. : Structural Review oI PV Array Mounting System ) Step 1 ls the array to be mounted on a defined, permitted roof structure?Yes lNo U No due to non-compliant roof or a ground mount. submit completed worksheet.fot the stuctute WKS I RooJ Infonnation: 1 . ls the roofing type lightweight (Yes = composirion, lighrweighr masonry, meral, erc...)

Does the roof have a single roof coverrngl @ves !r,lo Il No, submit completed wothsheet Jor rooJ structure WKSl. l. Provide method and type of weatherproofing roof penetrarions (e.g. nashing. caulk)flashing, m1 M ounting Sy stem Inforlnation l. Is lhe mounting structure an en ineered product designed to mount PV modules with no more than an l8'gap beneath the module frames?Yes ! t,to I! No, provide detaib of sffuctural attachment certiled by a design proJessional. 2. For manufactured mounting systems, hll our informarion on the mounting system below a.

Step 2: Electrical Review o[ PV System (Calculations lor Electrical Diagram) ln order for a PV system to be consldered for an expedited permit process, the following must apply: 1. Pv modules, utility-interactive inverters, and combiner boxes are idenrihed for use in PV systems. 2. The PV array is composed of 4 series srrings or less per inverter. 3. The total inverter capacity has a continuous ac power output I5,440 Watts or less 4. The ac interconnection point is on the load side of service disconnecting means (690.64(B)). 5. One ofthe standard electrical diagrams(El.l. El.la. El.lb. or El.lc) can be used ro accurately represenr rhe PV system.
