The'information in this guideline is inrended to help local jurisdictions and contractors identify when PV sysrem installations are simple, needing only a basic review and when an installarion is more complex. It is likely that 50%-75% of all residential systems will comply with these simple crireria. For projec6 thal fail to meet the simple criteria. resolution steps have been suggested to provide as a path ro permit approval. lle q uir ed I nJ ortnat i ott J o r f'ermi t : L Site plan showing location of major componenE on the propeny. This drawing need not be exactly to scale, but it should represent relative location of components at site (see supplied example site plan). PV arrays on dwellings with a f' perimeter space at ridge and sides may not need separale hre service review. 2.
