EXPEDITED PER,\1IT IROCESS FOR SMALL-sCALE PV SYSTEMS <br />STANDARD STRINC SYSTEM <br />The information in this guideline is intended to help local lurisdictions and contractors identih/ when PV system installations <br />are simple. needing only a basic review and when an installation is more complex It is likely that 50 % '75 % of all residenrial <br />systems will comply with these simple criteria.
