Thinking about going solar in Prescott Valley but want to know the real costs and savings for 2026? The great sun exposure here makes solar a powerful option, but the financial outcome now depends heavily on your utility's rules. With Arizona Public Service (APS), the key is to use the energy you produce, as selling it back to the grid isn't as lucrative as it once was. This guide breaks down the current costs, savings, and incentives available to you.

2026 Solar Panel Costs in Prescott Valley
For an average home in the area, a 6.0 kW solar system is a common size. The estimated upfront cost in 2026 is $13,500. After applying Arizona's $1,000 state tax credit, the final net cost is around $12,500.
Many homeowners also consider adding a battery to store energy. A 6.0 kW system paired with a 10 kWh battery has an estimated gross cost of $28,500. The net cost after the state credit would be approximately $27,500. This setup provides backup power and helps you use more of your own solar energy, which is critical under current APS rules.
Incentives & Tax Credits
State & Local Solar Incentives for 2026
With the 30% federal residential solar tax credit no longer in effect, Arizona's state-level incentives are more important than ever for making solar affordable:
- $1,000 Arizona Tax Credit: Homeowners can claim a one-time state tax credit for 25% of the system cost, up to a maximum of $1,000.
- No Sales Tax: Solar equipment and installation are exempt from state sales tax, reducing your total cost by thousands of dollars.
- No Property Tax Increase: An owned solar system adds value to your home without increasing your property tax bill. This makes it a valuable home improvement that can also enhance resale appeal for future buyers.

How APS Net Billing Affects Your Solar ROI
In Prescott Valley, APS uses a 'net billing' system. This means when your panels produce more electricity than your home is using, the excess power is sent to the grid. However, APS only credits you about 6.2 cents per kWh for that exported power. Since you pay more than double that—around 15.6 cents per kWh—to buy electricity from them, the math is clear: using your own solar power is worth twice as much as selling it. This is the primary reason battery storage is now strongly recommended, as it allows you to keep that valuable energy for yourself.
Projected Savings
Projected Annual Savings
The value of solar is no longer just about generating power—it's about replacing your most expensive grid power. With electricity rates from APS around 15.6 cents per kWh, every kilowatt-hour you generate and use at home is direct savings.
- A 6.0 kW solar-only system is projected to save about $1,004 annually, with an estimated payback period of 11.5 years.
- By adding a 10 kWh battery, you can store midday solar power for use in the evening. This increases the modeled annual savings to $1,256. The payback period extends to about 16.0 years due to the higher initial cost, but you gain greater control over your power bill.
Furthermore, locking in your energy costs with solar provides a hedge against rising utility rates. If grid power becomes more expensive in the future, your savings will grow over time.
