Planning a solar panel installation in Arizona in 2026 starts with understanding available incentives. These programs can reduce upfront costs and increase long-term savings.
Federal, state, and utility incentives are evolving, and major changes are expected in 2026. This guide explains what is currently available so Arizona homeowners and businesses can make informed decisions.
What’s Happening with the Federal Solar Tax Credit in 2026?
The most widely known incentive for solar has been the federal investment tax credit (ITC), officially called the Residential Clean Energy Credit. For years, this credit allowed homeowners to reduce their federal tax bill by 30 percent of the cost of a qualifying solar system.
Changes Coming in 2026
Under current federal law, the 30 percent residential solar tax credit is set to expire after December 31, 2025 unless Congress extends it.
- Systems installed and operational before this date typically qualify for the full credit.
- Systems installed in 2026 are not expected to receive the same 30 percent benefit.
- Any extension or modification of this credit is subject to new legislation and IRS rulemaking, so homeowners should monitor for updates.
Because policies can change, homeowners should check IRS updates or consult a tax professional before installing solar in 2026.
State Incentives Available in Arizona in 2026
Arizona still offers state tax incentives and exemptions that apply regardless of federal changes.
Arizona Residential Solar and Wind Energy Systems Tax Credit
Arizona offers a state income tax credit of up to 25 percent of the installed cost of a qualifying solar system, with a maximum credit of $1,000 per taxpayer.
Key points:
- The credit applies when you file your Arizona state return.
- If your tax liability is less than the credit, some or all of the unused portion may be carried forward for future years, subject to Arizona tax rules.
- This incentive continues to provide meaningful savings on state income taxes.
Sales Tax Exemption for Solar Equipment
Solar panels and related equipment that qualify under Arizona law are exempt from state sales tax, which reduces the upfront cost of a system purchase and installation.
Property Tax Exemption for Solar Value
Installing solar panels can increase your home’s value. Arizona offers a property tax exemption on that added value.
This means your property taxes will not increase due to your solar system.
Utility Incentives and Programs in 2026
Many Arizona utilities offer solar-related credits and programs. These may still be available in 2026, but details can change over time.
Common utility incentives include:
- Net Billing Credits: Many utilities offer net billing, where excess solar energy exported to the grid earns credits that offset future energy use.
- Battery Storage Incentives: Some utilities provide additional incentives or credits for pairing batteries with solar, especially if the system can support grid reliability.
- Time-of-Use (TOU) Credits: Solar systems may benefit from TOU billing if they generate during high-value hours of the day.
Utilities like APS and SRP offer these programs. However, credit rates and rules can change. Homeowners should check with their provider for the latest details.
Why 2026 Is a Turning Point for Solar Incentives
Several factors make 2026 an important year for solar incentives in Arizona:
- The federal solar tax credit may expire or change.
- State incentives will remain but offer smaller savings.
- Utility billing structures may shift and affect solar value.
Because these factors vary by system and provider, homeowners should review all options before installing solar.

Can utility net billing still reduce my electric bills?
Yes. Net billing and related utility credits generally remain available, though each utility may adjust rates, program rules, and valuation of exported solar energy.
Is solar still worth it in Arizona without the federal tax credit?
Many Arizona homeowners still find solar valuable due to high sunlight, rising electricity prices, state incentives, property exemptions, and ongoing utility billing credits.
Should I install solar before federal incentives change?
Homeowners who want to capture the full federal solar tax credit should aim to have systems installed and commissioned by the end of 2025. Solar projects in 2026 should be evaluated based on current rules, available incentives, and expected long-term savings.
