. EXPEDITED PERMIT PROCESS FOR SMALL-SCALE PV SYSTEMS STANDARD STRINC SYSTEM The informalion in this guideline is inrended to help local Jurisdicrions and conrractors identify when PV system installations are simple. needing only a basic review and when an insGllation is more complex. It is likely that 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 permu approval Required Information Jor Perrnit: I Site plan showing location of major components on the properry. This drawing need nor be exacrly to scale. bur it should represent relative location of components at sire (see supplied example site plan). PV arrays on dwellings with a S perimeter space at ridge and sides may not need separate nre service review. 2. Electrical diagram showing PV array configuration. wiring system, overcurrenr prorection. rnvertet disconnects, required signs, and ac connection to building (see supplied srandard electrical diagram). 3. Specihcation sheets and installation manuals (if available) for all manufacrured componenrs including, bur not limired ro, PV modules, inver|er(s). combiner box. disconnects, and mounring sysrem.

Step 2 ' Electrical Review of PV System (Calculations lor Electrical Diagram) In order for a PV system to be considered for an expedited permit process, the following must apply: l. PV modules, utility-interactive inverters, and combiner boxes are identified for use in PV sysrems. 2. The PV array is composed of 4 series strings or less per inverrer. l. The rotal inverter capacity has a conrinuous ac power output 15,440 Watts or less 4. The ac inrerconnecrion poinr is on the load side of service disconnecting means (690.64(B)). 5. One ofthe srandard electrical diagrams (El.l, ELla, El.lb, or El.lc) can be used ro accurarely represenr the PV system. Interactive PDF diagrams are available a( www.solarabcs.org/permirring.
