EXPEDITED PER,\1IT IROCESS FOR SMALL-sCALE PV SYSTEMS STANDARD STRINC SYSTEM The information in this guideline is intended to help local lurisdictions and contractors identih/ when PV system installations are simple. needing only a basic review and when an installation is more complex It is likely that 50 % '75 % of all residenrial systems will comply with these simple criteria. For projects that fail to meet the simple criteria, resolution steps have been suggested to provide as a path to permit approval Required InJormation fot Pennit: l Site plan showing location of ma.1or components on the property.
