Licensing of solar installers and equipment standards for solar power installations in Arizona
The licensing of solar installers and solar panelinstallations are different from state to state and even county to county, but they generally cover these three things;
- Interconnection Regulations
- Licensing and or qualifications of Solar Installers
- Equipment Standards or Certification
Arizona has no specific licensing requirements for those wishing to install solar power systems except for the fact that the installation of solar power is considered electrical work and so normal state based licensing would require that the installer be a licensed electrical contractor in Arizona. Also there is no specific state wide standard for solar power equipment in Arizona but equipment would need to meet general requirements for electrical equipment in that state. Most states that have no standards rely on the California Energy Commissions approved products list. However, utilities and counties may have their own standards for equipment that they require and so it would be prudent for you to first check with your local electricity utility before purchasing any equipment. Alternatively, if you request quotes from local installers through this site they will be able to advise you of any applicable local equipment standards.
Interconnection Standards or Regulations
There are no complete system installation requirements. There are, however, some component and subsystem installation requirements The Registrar of Contractors requires an electrical contracting license for installation of many solar photovoltaic systems. All installations must meet or exceed the UBC and NEC at a minimum, and any code(s) adopted by the municipality in which the device is being installed. There are subsystem installation and component certification requirements for photovoltaic modules and battery systems as required by the specific application. The installer is responsible for ensuring that the subsystem and product installed meets or exceeds all applicable requirements. The photovoltaic (PV) modules and installation must meet or exceed the following testing/safety/performance standards as required by the specific installation (asterisk * denotes required for all modules and installations): All applicable NEC requirements*, U.L. 1703*, JPL Block V,CEC Specification 503, IEC 904-3, IEC 1215. In addition, the PV modules and related components must meet or exceed the following testing/safety/performance standards as required by the specific installation:USHUD approval, RVIA approval. All connections to the electric utility grid must be made with the permission, approval and cooperation of the utility owning, operating and/or maintaining the distribution system. All components and their installation must be capable of protecting the existing grid and its operators and maintenance personnel from damage and injury per the instruction and approval of the utility responsible for the line access.
