How much do solar panels really cost in Drexel Heights, and what kind of savings can you expect in 2026? With Tucson Electric Power (TEP) providing electricity and Arizona's abundant sunshine, the potential for solar is strong. However, the financial outcome depends heavily on system design, current incentives, and TEP's rules for crediting exported energy.

For many homeowners, the key to maximizing solar value is focusing on self-consumption—using the power you generate directly in your home. This approach helps offset the most expensive electricity and provides a buffer against future rate hikes from TEP.

Benchmark Cost Analysis

Solar Panel System Costs in Drexel Heights (2026)

The following estimates are for an 8.3 kW solar system, sized to meet the needs of a typical Drexel Heights home with an average monthly electric bill of around $179.

  • Solar Panels Only: The estimated upfront cost is $18,675. After applying the available Arizona state tax credit, the net cost is reduced to approximately $17,675.
  • Solar Panels + 10 kWh Battery: A combined system with storage has an estimated gross cost of $33,675. The net cost after the state incentive is about $32,675.

Adding a battery increases the initial investment but provides greater long-term financial benefits and the security of backup power, which is especially useful given TEP's export compensation structure.

Incentives & Tax Credits

Available Solar Incentives for Drexel Heights Residents

As of 2026, the primary incentives for going solar are at the state level. The federal tax credit for homeowners is no longer in effect for new installations, but Arizona provides a solid support structure:

  • $1,000 State Tax Credit: Arizona offers a personal income tax credit for 25% of the cost of a solar system, up to a lifetime maximum of $1,000.
  • Property Tax Exemption: The value added to your home by a solar installation is exempt from property taxes, so your tax bill won't go up.
  • Sales Tax Exemption: The purchase of major solar energy equipment is exempt from Arizona's state sales tax, lowering your total out-of-pocket cost.

How TEP's Export Rate Affects Solar ROI

Tucson Electric Power uses a net billing program where surplus solar energy sent to the grid is credited at a low, avoided-cost rate. This analysis models that export rate at just 5.1¢ per kWh—roughly a third of the price you pay to buy electricity from TEP.

This is the central reason a battery is recommended. Instead of selling your valuable solar power for pennies, a battery lets you store it and use it later to offset power that would have cost you over 15¢ per kWh. This self-consumption strategy is the most effective way to maximize your savings and reduce your dependence on the grid.

Projected Savings

Projected Monthly and Annual Savings

A solar system saves you money by producing power that you would otherwise have to buy from TEP at their full retail rate (around 15.6¢ per kWh). The more solar energy you use onsite, the greater your savings.

Because TEP's export credits are low, pairing solar with a battery is recommended to store excess daytime energy for use at night. This strategy significantly increases the value you get from your system.

  • A solar-only system (8.3 kW) is modeled to save a homeowner about $1,335 per year, leading to a payback period of approximately 12.0 years.
  • By adding a 10 kWh battery, the estimated annual savings jump to $1,910. While the payback period extends slightly to 13.4 years due to the higher cost, the system delivers nearly $600 more in savings each year and protects you from outages.

Furthermore, an owned solar system is a long-term asset that can improve your home's resale appeal to future buyers.

Local Questions Answered

Is solar still a good investment in Drexel Heights without the federal tax credit?
Yes, it can be. The financial return now relies more on maximizing self-consumption, especially with TEP's low export rates. Arizona's state incentives, like the $1,000 tax credit and sales tax exemption, still help make it affordable. An owned system also protects you from future TEP rate increases.
How much does a solar battery add to the cost?
Based on this 2026 estimate, adding a 10 kWh battery costs approximately $15,000. While this increases the payback period, it also boosts annual savings by over 40% (from $1,335 to $1,910) and provides valuable backup power.
