EXPEDITED PERMIT PROCESS FOR SMALL-SCALE PV SYSTEMS STANDARD STRINC SYSTEM The information in this guideline is in:ended ro help local jUrisdictions and connactors rdentrfy when PV system insrallarions are simple, needing only a basic review and when an installation is more complex. lt is :ikely that fi%-75% of all residenrial systems will comply wiLh these sirnpls criteria. For projects that fail to nleet the simple criterfa. resolution steps have been suggested to provide as a parh ro permit approval. Reqdteil InJonnttion fot Pennit: l. Slte plan showing locarion of major components on the properry. This drawing need not be exacrty to scale, bur it should represent .elative location of components at sire (see supplied example site plan). PV arrays on dwelllngs with a 3' perimeter space at ridge and sides may not need separare hre service review. 2. Electrical diagram showlng PV array conhguration, wiring system, overcurrenL protection, inverteC disconnec6, required signs, and ac connection to building (see supplied standard elecrrical diagram). 3 specihcation sheeB and insrallarion manuals (if available) for all manufactured components including, bur nol limired ro, PV modules, invefier(s), combiner box disconnects, and mounring sysrem.

Step 2: Electrical Review o[ PV System (Calculations lor Electrical Diagram) tn order for a PV system to be considercd for an expedited permit process, the followtng must apply: 1 PV modules. utiliry-interactive inver(ers. and combiner boxes arc identifred for use in PV systems. 2. The Pv array is composed of 4 senes strings or less per inverter 3. The total inverter capacity has a continuous ac powcr oulput :3.440 Watts or less 4.' The ac interconnection point is on the load side of service disconnecring means (690.64(B)). 5. One ofrhesrandard electrical diagrarns (El.l.
