Arizona licensing & incentives context
Arizona state tax credit was limited — rely primarily on 30% federal ITC. SRP and APS export credits differ significantly.
Arizona combines excellent sun (6+ peak sun hours) with mature installer competition in Phoenix and Tucson. APS and SRP have different net billing rules — critical to model savings accurately.
