For homeowners in Goodyear, the intense Arizona sun makes rooftop solar a powerful tool for managing high summer electricity bills. As of early 2026, the economics of solar have shifted. While the main federal tax credit for homeowners is no longer available for new systems, strong state-level incentives in Arizona combined with high solar production keep it a compelling investment. The key is designing a system that works intelligently with local utility export rules to maximize your savings.

Solar & Battery System Costs in Goodyear (2026)
Here’s a look at the estimated costs for a typical 8.5 kW solar installation, designed to offset a significant portion of a home's electricity needs. These figures include Arizona's state tax credit.
- Solar-Only System (8.5 kW): The estimated net cost is around $18,125 after applying the $1,000 Arizona state tax credit.
- Solar + Battery System (8.5 kW solar with 10 kWh battery): The estimated net cost is approximately $33,125 after the state credit. Adding a battery increases the upfront cost but significantly improves how much of your own solar power you can use, boosting annual savings.
These costs are modeled estimates and can vary based on equipment, installer, and roof complexity. An owned solar system may also support your home's resale appeal in the long run.
Incentives & Tax Credits
Arizona's Solar Incentives for 2026
Even without the federal tax credit, Arizona offers some of the best state-level support for homeowners going solar.
- State Income Tax Credit: Arizona provides a personal tax credit of 25% of the system's cost, capped at a lifetime maximum of $1,000. This directly reduces your state tax liability.
- Sales Tax Exemption: You won't pay any state sales tax on the purchase of your solar equipment, which saves a significant amount on the total project cost.
- Property Tax Exemption: Installing solar panels increases your home's value, but thanks to a state exemption, your property taxes will not go up as a result.

Understanding Export Rates and the Value of a Battery
In this area, the value of electricity you send back to the grid is much lower than the price you pay for electricity you pull from it. We've modeled the export rate at around 6 cents per kWh, while the retail rate is over 15 cents per kWh. This difference is why a battery is highly recommended.
Instead of exporting your excess solar energy for a small credit, a battery stores it. You can then use that stored energy during the evening or on cloudy days, avoiding the need to buy expensive power from Roosevelt Irrigation District. This strategy, known as self-consumption, dramatically increases your system's value and your control over your monthly electricity bill.
Projected Savings
How Much Can You Actually Save on Your Electric Bill?
Savings depend heavily on whether you add a battery. With lower export compensation rates from utilities like Roosevelt Irrigation District, using your own solar power is far more valuable than selling it back to the grid.
- A solar-only system is modeled to save around $1,412 annually, leading to a payback period of about 11.7 years.
- Pairing solar with a battery increases the estimated annual savings to $1,910. While the payback period extends to 13.5 years due to the higher initial cost, the system provides greater bill reduction and energy independence from day one.
If grid electricity becomes more expensive over time, rooftop generation can offset costlier power in future years, making the investment even more valuable.
