Incentives & Tax Credits
Key Arizona Solar Incentives for 2026
Without a default federal credit, leveraging state benefits is more important than ever. Buckeye homeowners can take advantage of several key Arizona perks:
- Residential Solar Tax Credit: Arizona offers a personal tax credit of 25% of the system's cost, capped at a maximum of $1,000. This is a direct, one-time reduction of your state tax liability.
- Sales Tax Exemption: You pay zero sales tax on the purchase of solar panels and related equipment, which is already factored into the cost estimates. This provides significant upfront savings.
- Property Tax Exemption: Installing solar panels increases your home's value, but thanks to Arizona law, that added value will not increase your property taxes.

How Your Utility Handles Extra Solar Power
In most modern utility structures in Arizona, including those around Buckeye, the value of power you export to the grid is lower than the price you pay for power you import. You might pay $0.16 per kilowatt-hour (kWh) for electricity but only receive a credit of around $0.06 per kWh for your surplus solar energy.
This difference is why battery storage is highly recommended. A battery stores your excess solar energy generated during the sunny afternoon. Instead of selling it to the grid for a low credit, you can use that stored energy to power your home in the evening, avoiding the need to buy expensive electricity. This strategy maximizes the value of every kilowatt-hour your panels produce.
Projected Savings
Projected Energy Savings in Buckeye
A solar installation directly reduces how much power you need to buy from the grid. With Buckeye's climate driving heavy air conditioner use, those savings add up quickly.
- The solar-only system is modeled to save approximately $1,324 in the first year, with a payback period of about 11.7 years.
- Pairing panels with a battery increases your self-consumption, boosting first-year savings to around $1,910. While this configuration has a longer payback of 16 years due to the battery's upfront cost, it provides greater long-term bill reduction and the crucial benefit of backup power during grid outages.
