Complete Guide to Solar Energy in Arizona
Your complete resource for solar energy. Everything you need to know about solar laws, solar costs, solar financing, and solar installation in Arizona.
Why Arizona is Perfect for Solar Energy
Exceptional Sunshine
Arizona receives over 300 sunny days per year and ranks #1 nationally for solar radiation, providing the most optimal conditions in the United States for solar energy generation year-round.
High Electricity Rates
With peak rates reaching $0.15-$0.22/kWh from major utilities (APS, SRP, TEP), solar provides substantial savings on monthly utility bills, with rates expected to increase 2-14% through 2026.
Strong Financial Incentives
Arizona offers 25% state credit up to $1,000 of installation cost as well as property tax exemption.
Robust Legal Protections
Arizona law (A.R.S. § 33-1816) protects homeowners’ rights to install solar systems. HOAs cannot prohibit solar installations and restrictions must not reduce efficiency by more than 10% or add over $1,000 in costs.
