EXPEDITED PERMIT PROCESS FOR SMALL-SCALE PV SYSTEMS MICRo-INVERTER The informarion in this guideline is intended to help local jurisdictions and conrracrors idenrify when Pv sysrem insrallarions are simple, needing only a basic review and when an insmllaion is more complex. lr is likely rhar 50% -75% of all residenrial systenis will comply wirh these simple criteria. For projects lhat fail to meet rhe simple criteria, resolution steps have been su8lgested to provide as a parh ro permit approval. Reqrbed Information fot Pennit: 1. Site plan showing location of major components on the properry This drawing need not be exacrly ro scale. but ir should represent relative location of components at site (see supplied example site plan). PV arrays on dwellrngs with a 3'perimeter space at ridge and sides may not need separate frre service review 2. Electrical diagram showing PV array configuration, wiring system, overcurrenr protection, inverrer, disconnects. required signs. and ac connecrion ro building (see supplied srandard elecrrical diagram). 3. Speci6carion sheets and installation manuals (if available) for all manufactured components including, bur nor limired to, PV modules, inve er(s), combiner box, disconnects. and mounting system.

Step 2: Electrical Review o[ PV System (Calculations for Electrical Diagram) In order for a PV s!6tem to be considercd for an expedited permit process, tlle fouowing mtrst apply: l. PV modules, ulility-interactive inverters. and combiner boxes are identified for use in PV systems. 2. The PV array is composed of 4 series strings or less per rnverrer. 3. The total inverrer capacity has a continuous ac power ourput 13.440 Watts or less 4. The ac interconnection point is on the load side oF service disconnecting means (690.64(8)). 5. One of the standard electrical diagrams (El I , E l I a. E l. I b. or E l I c) can be used ro accurarely represenr rhe PV system.
