Arizona law contains detailed consumer protection provisions, including regulations on door-to-door sales, advertising requirements, prohibition of deceptive practices, and a construction recovery fund.
Specific to the solar industry, A.R.S. § 44-1763 details contract requirements and disclosures for distributed generation. Companies who lease or sell solar systems to consumers in Arizona must provide a certificate that the system complies with Arizona law and must receive specific acknowledgment from customers on contract terms, including warranty information, cost, payment schedule, utility rates, and others.
Arizona is a leading energy storage market, supported by rapid solar expansion and strong market fundamentals.
Streamlined interconnection processes and supportive policies are enabling faster deployment, while utilities continue to procure storage to maintain reliability as solar penetration increases. Arizona’s hundreds of solar and storage companies invest billions in the state annually, positioning the state as a key hub for both deployment and manufacturing.
