EXPEDITED PERTilIT PROCESS FOR SMALL-SCALE PV SYSTEMS MICRO-INVERTER The informarion in this guideline is intended to help local jurisdictions and contracbB identify when Pv s)6rem insrallarions are simple, needing only a basic review and when an installation is more complex. It is likely that 50 %-75 % of all residenrial systems will comply with these simple criteria. For projecrs that fail ro meet rhe simple criteria, resolurion sreps have been suggested to provide as a path to permit approval. Requi/ed Infonn^tion for Pennit: l. Site plan showing location of major components on rhe properry. This drawing need not be exacrly to scale, bur ir should represent relative location of componen!s at sire (see supplied example sire plan). Pv arrays on dwellings with a 3'perimeter space at ridge and sides may not need separate nre service review. 2. Elecrrical diagram showing PV array conngurarion, wiring system, overcurrent protection, invenet disconnects, required signs, and ac connecrion ro building (see supplied standard electrical diagram). 3. Specihcation shee$ and installarion manuals (if available) for all manufactured componenrs including, but not limited to. PV modules. inverter(s), combiner box, disconnects, and mounting sysrem. Step 1 : Structural Review of PV Array Mounting System Is the array to be mounted on a dehned, permitted roof structure?Yes E r,lo U No due to non-compliant roo.f or o. ground mount. submit completed worl.sheet Jor the structure WKS I Roof Informatioa: 1.

Does the roof have a single roof covering? EVes Eno II No, submit conryleted worhsheetlor roof stucture WNSI. 5.

Step 2: Electrical Review o[ PV System (Calculations lor Electrical Diagram) In order tor a PV system to be considercd for an expedited permit process, the following must apply: l. PV modules, utility-inreractive inverters, and combiner boxes are identihed for use in PV sysrems. 2. The PV array is composed of 4 series strings or less per inverter. 3. The loral invener capaciry has a continuous ac power ourpur I f,440 Watts or less 4. The ac interconneclion point is on the load side of service disconnecring means (690.64(8)). 5. One ofthe sEndard electrical diagrams (E I . 1 , E 1 . I a. E I . I b, or E I .
