Solar & Wind Equipment Certification

Collectors, heat exchangers, and storage units of solar energy systems -- and the installation of these systems -- sold or installed in Arizona must have a warranty of at least two years or guarantee the energy production output for two years. The remaining components of the system and their installation must have a warranty of at least one year. Solar energy systems are subject to random inspections by the state's registrar of contractors.

Any person manufacturing, furnishing for installation, or installing a solar energy system must provide a written statement of warranty, responsibilities assumed or disclaimed, and performance data as part of the agreement for the financing, sale, or lease of the system. Installers must also comply with any state and federal consumer protection, rating, certification, performance, marking, installation, and safety standards. 

With the exception of systems installed by the final owner, systems installed in Arizona must be installed by licensed solar contractors. Furthermore, the installation of a solar energy system must meet the requirements of all applicable fire, safety, and building codes.
