Estimated 2026 Solar System Costs in Sun City West
The price of a solar installation depends on whether you include battery storage. Here are the modeled costs for an 8.3 kW system, sized to cover a typical household's electricity needs, before applying Arizona's state tax credit.
- Solar Panels Only System: The estimated gross cost is $18,675.
- Solar Panels + 10 kWh Battery System: The estimated gross cost is $33,675.
After applying Arizona’s $1,000 state tax credit, the net costs become $17,675 and $32,675, respectively. Additionally, Arizona's sales tax exemption on solar equipment provides further savings on the initial purchase.

How APS Export Rates Affect Solar Economics
In 2026, APS operates under a net billing program where the value of exported solar power is much lower than the retail rate of electricity. You might pay APS over 15 cents for a kilowatt-hour (kWh) of electricity but only get a credit of around 6 cents for each kWh your system sends to the grid.
This economic reality is why a battery is recommended. Instead of selling your valuable solar energy for pennies, a battery lets you save it for when you need it most—typically in the evening after the sun goes down. This maximizes your savings by offsetting the most expensive power you would otherwise buy from APS.
Projected Savings
Projected Savings and Payback Period
Your total savings depend on how much of your own solar power you use directly. Because exporting surplus power to APS yields a low credit, using a battery to store and use that energy later significantly improves the system's financial performance.
- A solar-only system is modeled to save approximately $1,443 per year, leading to a payback period of around 11.3 years.
- Adding a battery boosts self-consumption. The solar-plus-battery system is estimated to save $1,910 per year. The higher upfront cost results in a longer payback of about 13.4 years, but it delivers greater savings over the life of the system and more independence from the grid.
An owned solar system can also support your home's resale appeal, making it an attractive feature for potential buyers concerned about future energy costs.
