PV SYSI I.MS STAN I)AtTI) STiTING S\'5 TEM The information in this guideline is inrended to help Iocal jurisdict ions and contractors identify when PV system insrallarions are simple. needing only a basic review, and when an installation is more complex. lt is likely thar 50%-75% of all residenrial systems will comply with these simple criteria. For projects that fail to meer the simple criteria. resolurion sreps have been suggested to provide as a path to permit approval. Requirccl Information Jor Permit: L Site plan showing location of major components on the property. This drawing need nor be exacrly ro scale, bur ir should represent relative locarion of components at site (see supplied example sire plan). PV arrays on dwellings with a S perimeter space at ridge and sides may not need separate hre service review. 2.
