Solar incentives in Arizona
What type of solar incentives are available?
Several types of incentives can help you go solar. This section covers the solar incentives available in the Arizona, but you can learn more about the national context of solar incentives on our national solar incentives page.
State tax credits
Arizona offers an individual tax credit of 25% of the cost of the installation of a solar energy system, worth up to $1,000. The credit can be claimed the year of the installation of your solar system. If your tax liability is under the amount of the credit, you can roll over the credit into subsequent tax years, up to five years from your installation. The credit is not available to taxpayers who lease solar systems or enter into power purchase agreements with third parties.
State property tax exemption
Installing solar adds value to your property. However, Arizona law exempts solar installations from increasing your property tax liability. Contact your county assessor for how and when to submit the proper paperwork to qualify for the exemption.
State sales tax exemption
Arizona offers a state sales tax exemption to registered sellers of solar and related equipment. City sales tax may still apply.
Arizona Public Service
Arizona Public Service (APS) has a solar communities program that installs solar for free on qualified homes of limited to moderate income. The program provides a $30 monthly credit on your electric bill for 20 years. APS will own the solar panels and all of the power generated. While this may help some customers with the upfront cost of solar, studies show utility-owned rooftop solar programs disproportionately benefit utilities when compared to self-ownership of solar by customers.
Salt River Project
SRP offers a Battery Storage Incentive Program for its customers. The first 4,500 SRP customers to qualify can receive a rebate of $300/kWh of storage capacity, worth up to $3,600 for installing a residential battery storage system. The program lasts 36 months beginning on May 1, 2018 and ending April 30, 2021.
SRP has a $250 rebate for systems, like smart thermostats, known as demand management systems. These can help you lower your energy use during times of high energy usage and in doing so, avoid expensive demand charges. The utility also offers incentives for installing solar hot water systems.
Tuscon Electric Power
Tucson Electric Power does not currently offer any incentives for rooftop solar, but it does offer rebates for a variety of energy efficiency measures.
Local government incentives
The City of Mesa offers solar incentives worth up to $1,000 for residential customers of the city’s municipal electric utility. Incentives for commercial solar projects are worth up to $10,000.
The City of Tempe offers a residential rebate program to refund permitting and some related fees.
