EXPEDITED PERMIT PROCESS FOR SMALL.SCALE PV SYSTEMS STANDARD STRING SYSTEM The information in this guideline is intended to help local jurisdictions and conrracrors identify when PV sysrem insrallations are simple, needing only a basic review, and when an installation is more complex. Ir is likely rhar 50% -75% of all residenrial sysrems will comply with rhese simple criteria. For projec6 that Fail ro meer the simple criteria, resolurion steps have been suggested to provide as a path ro permir approval. Required.
