Arizona does not consider renewable energy generating devices to add value to property—which means consumers don’t get taxed on the value added to the property by the energy installation.


Under Arizona’s law, both “active” and “passive” systems are eligible for the credit. 

The exemption was created under state law HB-2429 and expanded by HB-2332 defines “energy equipment” as equipment that harness energy equipment to produce energy primarily for on-site consumption from renewable resources, including wind, forest thinning, agricultural waste, biogas, biomass, geothermal, and low-impact hydropower. It also includes high performance building components in buildings or building components that meet or exceed the energy efficiencies of programs including Energy Star or LEED. 


To qualify for the exemption, property owners need to provide their county assessor with documentation of the purchase and installation of the equipment within six months. There’s no limit on this exemption—consumers can install as much qualifying equipment as they want, property tax-free.
