. EXPEDITED PERMIT PROCESS FOR SMALL-SCALE PV SYSTEMS MICRO-INVERTER The inforynaion in rhis guideline is intended ro help local jurisdicrions and conrractors idenrity when pv sysrem installarions are simple' needing only a basic review and when an installarion is more complex tr is likely thar 50% -lLx of ^ll residenrial sysrems will comply with these simple crileria. For projecs rhar fail to meer the simple crirciia, resolution sreps have been suggested ro provide as a parh ro permit approval. Requireil InJormatiotr for P*mit: l. site plan showing location of major components on rhe property. This drawing need nor be exactly ro scale, bur ir should represenr relative location of componenrs ar sire (see supplied examplJ sire plan). pV arrays on dwellingswith a 3'perimeter space at ridge and sides may not need separate hre service review. 2 Electrical diagram showing Pv aray configuration, wiring system, overcurrent proteclon. inverter, disconnecls, required signs, and ac connection ro building (see supplied srandard electrical diagraml. 3. specihcarion sheets and installation manuals (if available) for all manufacrured componenrs including. bur nor limited to, PV modules. invener(s), combiner box, disconnects, and mounring sysrem.

Step 2: Electrical Review o[ PV System (Calculations lor Electrical Diagram) In order for a Pv s]6tem to be considercd for an expedited permit prccess, the following must apply:I PV modules, uriliry-interacrive inverters, and combiner boxes are identi6ed for use in pV systems. 2. The PV array is composed of 4 series strings or less per inverter. 3. The total inverter capaciry hasa continuous ac power ourput t3.440 Watts orless 4. The ac interconnecrion point is on rhe load side of service disconnecting means (690.64(8)). 5. One of rhe srandard elecrrical diagrams (E l I , E L I a, E 1 I b. or E L I c) can be used ro accurarely represenr rhe pV system. lnreractive PDF diagrams are available at www.solarabcs.org/permifting.
