EXPEDITED PERMIT PROCESS FOR SMALL.SCALE PV SYSTEMS <br />STANDARD STRING SYSTEM <br />The information in this guideline is intended to help local jurisdict ions and conlraclors identity when PV syslem inslallarions <br />are simple, needing only a basic review and when an installation is more complex. ll is likely that 50%-75% of all residential <br />systems will comply with these simple criteria. For projects that fail to meet the simple crileria. resolulion sleps have been <br />suggested to provide as a path to permit approval <br />Requireil Information fot Perinit : <br />L Site plan showing location of ma]or components on the property. This drawing need not be exactly lo scale, but it <br />should represent relative location oI 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 seParate nre service review. <br />2.

PV modules, utiltty-interactive inverters, and combiner boxes are identified For use in PV systems. <br />2. The PV array rs composed of 4 series strings or less per inverter. <br />l.
