. EXPEDITED PERMIT PROCESS FOR SMALL-SCALE PV SYSTEMS <br />STANDARD STRING SYSTEM <br />The information in this guideline is intended to help local Jurisdicrions and contractors identify when PV system installaoons <br />are simple, needing only a basic review, and when an insrallarion is more complex. lt is likely that 50%-75% of all residential <br />systems will comply with these simple criteria For projects rhat fail to meer the srmple criteria. resolution steps have been <br />suggested ro provide as a path ro permit approval. <br />Requtred InJofination for Pennit : <br />I Site plan showing location of ma.1or componen(s on the property This drawing need not be exactly to scale. but it <br />should represent relative location of components at site (see supplied example site plan). PV arrays on dwellings <br />with a 3 perimeter space at ridge and sides may not need separare hre service review <br />2 Electrical diagram showing PV array conhguration. wiring sysrem. overcurrent protection, inverter. disconnects. <br />required signs, and ac connection to building (see supplied srandard elecrrical diagram). <br />5. Specincarion sheets and installation manuals (if available) for all manufactured components including, but not <br />limited to. PV modules, inverrer(s), combiner box, disconnects, and mounting system. <br />Step 1 : Structural Review of PV Array Mounting System <br />ls the array to be mount€d on a defrned, permitted roof structure?

PV modules. utility-interacrive inverters. and combiner boxes are identified for use in PV systems. <br />2. The PV array is composed of 4 series strings or less per inverter <br />f. The rotal inverter capacity has a continuous ac power output 13.440 Watts or less <br />4. The ac inrerconnection point is on rhe load side of service drsconnecting means {690.64(B)). <br />5.
