Arizona’s Credit for Solar Energy Devices is a state tax credit that helps homeowners save money when they install solar panels on their Arizona residence. This nonrefundable tax credit reduces the amount of state income tax you owe, dollar-for-dollar, making solar energy more affordable for Arizona families.

To qualify for this credit, you must be an individual taxpayer who installs a solar energy device at your primary or secondary residence located in Arizona. The credit is nonrefundable, which means it can reduce your Arizona state tax liability to zero, but any unused credit amount cannot be refunded to you as cash. You’ll need to file Form 310 with your Arizona state tax return to claim this benefit.

While the official source doesn’t specify the exact credit amount or percentage, this incentive has been available for many years and continues to be offered for recent tax years through 2024. The credit applies to solar energy devices installed at your Arizona home, helping offset the upfront costs of going solar while supporting the state’s clean energy goals.

Arizona’s Property Tax Exemption for renewable energy equipment allows homeowners to exclude the added value of their solar panel system from their property tax assessment. This means that while your solar installation may increase your home’s overall value, you won’t pay additional property taxes on that increased value. The exemption applies to the full value of qualifying renewable energy equipment, including solar panels, inverters, and related components.

To qualify for this exemption, your renewable energy system must be installed on residential property in Arizona and meet state requirements for renewable energy equipment. Property owners must file the appropriate forms with the Arizona Department of Revenue to claim this exemption. The exemption continues for as long as you own the qualifying renewable energy equipment, providing ongoing tax savings throughout the life of your solar system. This incentive helps make solar more affordable by ensuring homeowners don’t face higher property tax bills simply for investing in clean energy technology.

Arizona’s Solar and Wind Sales Tax Exemption removes state sales tax from the purchase and installation of solar and wind energy systems for your home. This means you won’t pay the standard Arizona sales tax (which varies by location but is typically around 5-10%) on your solar panels, inverters, batteries, and other system components, as well as the contractor’s installation services.

This exemption applies to all residential solar and wind energy devices sold at retail in Arizona, with no income limits or system size restrictions. The tax savings are automatic at the point of sale – you simply won’t be charged sales tax when you purchase your system. There are no application deadlines or expiration dates for this ongoing state policy. Keep in mind that while state sales tax is exempted, local sales taxes may still apply depending on your city or county, so check with your installer about the total tax savings you can expect in your specific location.

Net Billing in Arizona is a compensation system where solar homeowners receive credits for excess electricity their panels send to the grid. Unlike traditional net metering where you get full retail credit, net billing pays you a lower wholesale rate for your excess solar power. The credit rates vary by utility company, ranging from about 3.5 cents to 6.9 cents per kilowatt-hour, which is significantly less than what you pay for electricity from the grid.

Most Arizona utilities lock you into your export credit rate for 10 years once you connect your solar system, providing rate stability. However, you’ll typically need to switch to a time-of-use rate plan, and some utilities charge additional monthly fees for solar customers. At the end of each year, most utilities will either pay out excess credits above a certain threshold (usually $10-$25) or reset your account to zero, though some allow credits to roll over indefinitely. This system means your solar savings come primarily from using the power you generate during the day rather than from selling excess power back to the utility.
