These are recommended guidelines for solar PV generated by the Maricopa Association of Governments (MAG) Code Committee in order to institute a common standard among all building departments of communities in Maricopa County. The standard is not mandatory but its inclusion in local jurisdiction codes will provide a common basis for solar PV installations in Maricopa County. This info was provided by Anthony Floyd, City of Scottsdale, and member of the MAG Building Codes Committee.
Permit Submittal Requirements - Commercial Solar Photovoltaic (PV) Systems For Utility Grid-Tie Connection
In an effort to promote uniformity through MAG jurisdictions under the purview of life safety (NEC Article 690), the following submittal requirements are proposed as a MAG standard for securing necessary electrical/building permits for commercial solar photovoltaic (PV) systems:
-
Location of PV installation indicated on plans (roof plan and elevation).
-
Mounting details for PV panel installation.
-
Structural plans prepared and sealed by a State of Arizona registered engineer for support and uplift of PV panels.
-
Electrical one-line and three-line (showing phases, neutral and ground) diagram.
-
Electrical plans prepared and sealed by a State of Arizona registered electrical engineer.
-
Cut sheet and listing for inverter (DC to AC conversion).
-
Note on plans that PV equipment shall be installed in accordance with NEC 690 and posted with applicable warnings, signage & plaques per NEC 705-10, 690-17 & 690-64(b)(5).
-
Acknowledgement letter from utility company for grid-tie PV systems. Grid-tie encompasses not only paralleled inverters but also inverters that constitute a potential back feed source, (i.e. - those that are connected to the utility and are programmed in the "non-utility interactive mode" but have the capability of being re-programmed to back feed in the "utility interactive mode")
NOTE:
Local planning and zoning regulations involving such requirements as setback, height limitations, color, reflectivity or other design considerations, may apply.
See the local governing jurisdiction for further information.
