Is investing in rooftop solar still a smart move for homeowners in Maricopa in 2026? With intense summer heat driving up air conditioning costs, generating your own electricity is appealing. However, the financial return now depends heavily on which electric utility serves your specific address and how much they credit you for surplus power.
The straightforward 1-for-1 net metering of the past is gone, and the 30% federal tax credit has expired for new systems. Success with solar in 2026 is about designing a system that helps you use as much of your own power as possible, often with the help of a battery.

How Much Do Solar Panels Cost in Maricopa? (2026 Estimates)
The figures below are modeled for a typical Maricopa home and are intended as a starting point. They already factor in Arizona's sales tax exemption but do not include any federal tax credits.
- Solar Only (8.5 kW System): The estimated gross cost is $19,125. After applying Arizona's $1,000 state tax credit, the net cost is approximately $18,125. This system is designed to cover a large portion of your daytime energy needs.
- Solar + Battery (8.5 kW System with 10 kWh Battery): Adding storage brings the estimated gross cost to $34,125, or a net cost of $33,125 after the state credit. This configuration provides backup power and maximizes the value of your solar production by letting you use it at night.
Incentives & Tax Credits
Key Arizona Solar Incentives for 2026
Even without the federal ITC, Arizona provides strong local incentives that make solar a viable investment. Homeowners in Maricopa can benefit from:
- $1,000 State Tax Credit: Arizona offers a personal income tax credit for 25% of the cost of a solar system, capped at $1,000 for each residence.
- No Property Tax Increase: The value added to your home by an owned solar system is exempt from property taxes, so your tax bill won't go up.
- Sales Tax Exemption: Major solar components are exempt from state sales tax, lowering your upfront investment.
Beyond the direct financial perks, an owned solar system can be a significant asset when selling your home. It demonstrates lower, more predictable energy costs, which is a powerful selling point for buyers.

Navigating Export Rates in Maricopa
A critical detail for Maricopa homeowners is that different neighborhoods may be served by different utilities, such as Arizona Public Service (APS) or Electrical District No. 3. Each has its own specific rates and rules for crediting customers for excess solar generation.
Generally, the power you export to the grid is valued at a wholesale or 'avoided cost' rate, which is much lower than the retail rate you pay. Our model uses a conservative estimate of $0.059 per kWh for exported energy. Because this is significantly less than the ~15.6 cents per kWh you pay to buy electricity, simply producing excess power isn't enough. The goal is to use your solar power yourself, which is why a battery is often the most effective solution.
Projected Savings
Projected Electricity Bill Savings
A solar-only system can generate significant savings, estimated at around $1,412 in the first year. The estimated payback period for this setup is approximately 11.7 years. Your savings come from directly offsetting the power you would have bought from the grid during sunny hours.
Pairing solar with a battery increases your energy independence and your savings. By storing excess solar energy generated during the day, you can power your home through the evening and avoid buying expensive electricity. This strategy boosts the estimated first-year savings to $1,910. The higher initial investment results in a longer payback of around 13.5 years, but it offers better protection against rising utility rates and provides valuable power outage security.
