EXPEDITED PERMIT PRoCESS ,o* ,"o...,.0Til,,ii", .. U- STANDARD STRING SYSTEM The information in this guideline is intended ro help local jurisdictions and conrracbrs identify when Pv sysrem ins[alladons are simPle, needing only a basic review and when an installarion is more complex. lr is likely rhar 50%-75 % of all residenrial systems will comply wirh these slmple ffiteria. For projects thar fail ro meet the simple ffiteria, resolution sreps have been suggested lo provide as a pat}l to permit appmval. Regubed Informatlott for Permit: I Site plan showing locarion of major components on the propeny. This drawing need nor be exactly to scale, bur it should represent relative location of componen[s ar sire (see supplied example site plan). PV arrays on dwellings with a 3' perimerer space ar ridge and sides may not need separare fire service review. 2. Electrical diagram showing Pv array configuration, wiring system, overcurrenr protection, invefter, disconnecrc. required signs, and ac connecrion ro building (see supplied sEndard elecrrical diagram). 3. sPecihcation sheers and installation manuals (if available) for all manufacrured components including, but nor limited to, PV modules, inverter(s), combiner box, disconnects, and mounring sysrem.
