Analyst Note: Bill-based model (~8.3 kW)

Cost and savings sections below are sized to a typical system for this city’s average utility bill (~8.3 kW modeled). Typical monthly bill here: $179.17.

At this bill level, modeled system sizes are often in the mid-to-high single-digit kW range. Use the calculator below to match your actual usage.

High summer electricity bills are a fact of life in Marana, driven by the intense cooling demand. While Arizona's sun provides an abundance of solar energy, the financial benefits in 2026 depend entirely on your utility's rules. For homeowners served by Trico Electric Coop, sending excess solar power back to the grid may not offer the value it once did. This changes the math, making it critical to use the solar energy you generate directly in your home.

The key is maximizing 'self-consumption'—using your own solar power to avoid buying expensive grid electricity. This is where adding a home battery can significantly improve the economics of your system.

Benchmark Cost Analysis

Estimated Solar System Costs in Marana (2026)

Below are modeled estimates for a typical home in Marana. The final price depends on your roof, equipment choices, and installer. These figures account for Arizona's sales tax exemption on solar equipment but do not include the now-expired federal tax credit.

  • Solar Only (8.3 kW System): The estimated gross cost is around $18,675. After applying Arizona's $1,000 state tax credit, the net cost drops to approximately $17,675.
  • Solar + Battery (8.3 kW System with 10 kWh Battery): This combined system has an estimated gross cost of $33,675. The net cost after the state credit is approximately $32,675. The battery adds backup power and increases your ability to use your own solar energy after sunset.

Incentives & Tax Credits

Arizona's 2026 Solar Incentives for Marana Homeowners

While the 30% federal solar tax credit is no longer available for systems installed in 2026, Arizona offers several valuable state-level incentives that help reduce the cost and improve the return on investment:

  • Arizona Solar Tax Credit: Homeowners can claim a one-time state income tax credit of 25% of the system's cost, capped at a maximum of $1,000.
  • Property Tax Exemption: Installing a solar system will not increase your property taxes. The added value of the solar panels is exempt from your home's assessed value.
  • Sales Tax Exemption: You will not pay state sales tax on the purchase of major solar equipment, which reduces the upfront cost of your system.

An owned solar system can also be an attractive feature for potential home buyers, potentially supporting your home's resale appeal in a market where energy costs are a major concern.

Understanding Export Rates with Trico Electric Coop

In Marana, your utility's policy for crediting excess solar power is a critical factor. Under many current co-op structures, the electricity you send to the grid is purchased at a rate significantly lower than the retail price you pay for electricity. Our model uses a conservative export rate of about $0.059 per kWh, while you pay Trico Electric around $0.156 per kWh.

This difference is why a battery is recommended. Storing a kWh of solar power to use later saves you from buying a $0.156 kWh from the grid. Exporting that same kWh only earns you about $0.059. By storing it, you capture nearly three times the value from every solar kWh you don't use immediately.

Projected Savings

How Solar Can Reduce Your Trico Electric Bill

With a solar-only system, you could see first-year savings of around $1,412, leading to a payback period of about 11.5 years. This system is designed to offset a significant portion of your daytime electricity usage.

Adding a battery changes the equation. By storing excess daytime solar energy, you can use it during evening peak hours instead of selling it to the grid for a low rate. This boosts your annual savings to an estimated $1,910. While the higher upfront cost extends the payback period to around 13.4 years, it provides greater energy independence and higher long-term value, especially if utility rates from Trico Electric continue to rise.

Local Questions Answered

Why is a battery recommended for solar in Marana?
A battery is recommended because the compensation rate for exporting excess solar power to Trico Electric's grid is modeled to be much lower than the retail electricity rate. A battery lets you store your surplus solar energy and use it in the evening, maximizing your savings by avoiding high-cost grid power instead of selling your energy for a low credit.
What happens to my payback period if Trico Electric rates go up?
If utility rates increase over time, your payback period will likely shorten. Each kilowatt-hour your solar system produces becomes more valuable because it offsets more expensive grid power. This protection against rising utility costs is a key long-term benefit of owning a solar system.
Does the $1,000 Arizona tax credit apply to the battery too?
Yes, the Arizona Residential Solar and Wind Energy Systems Tax Credit applies to the total cost of the solar energy device, which typically includes the panels, inverter, and associated battery storage equipment. The credit is 25% of the cost, up to a lifetime maximum of $1,000.
