EXPEDITED PERMIT PRoCESS ,o* ,"o...,.0Til,,ii", .. U- <br />STANDARD STRING SYSTEM <br />The information in this guideline is intended ro help local jurisdictions and conrracbrs identify when Pv sysrem ins[alladons <br />are simPle, needing only a basic review and when an installarion is more complex. lr is likely rhar 50%-75 % of all residenrial <br />systems will comply wirh these slmple ffiteria. For projects thar fail ro meet the simple ffiteria, resolution sreps have been <br />suggested lo provide as a pat}l to permit appmval. <br />Regubed Informatlott for Permit: <br />I Site plan showing locarion of major components on the propeny. This drawing need nor be exactly to scale, bur it <br />should represent relative location of componen[s ar sire (see supplied example site plan). PV arrays on dwellings <br />with a 3' perimerer space ar ridge and sides may not need separare fire service review. <br />2.
