The average cost to install a solar energy system is $18,200 in Idaho after the full federal solar investment tax credit, which is more expensive than the national average of $16,715. Still, you can take advantage of a solar tax deduction, rebates and a low-interest loan to make a new system more affordable.

Key insights

  • You can take advantage of solar tax breaks, rebates and loan programs in Idaho.
  • The average federal tax credit value is $7,800 in Idaho.
  • Idaho residents who install solar panels save an estimated $11,478 over 25 years.

Solar incentives in Idaho

The federal solar investment tax credit (ITC) is the biggest factor in reducing the cost of going solar in Idaho. If you install a residential solar panel system by the end of 2032, you will receive a federal income tax credit equal to 30% of the system's total cost, including equipment, labor and permits.

The federal solar investment tax credit drops to 26% in 2033 and 22% in 2034

For example, in Idaho, a solar system costs $26,000 on average. At that price, you can get a $7,800 credit when you file your taxes.

The solar tax credit is not a rebate or refund — you must claim it when you file federal taxes in the year that your solar panel system becomes operational. To do this, you have to complete Form 5695. The credit is also nonrefundable, so any unused portion rolls over into the next tax year.

Statewide residential solar incentives in Idaho

Idaho has three ways to save on solar systems. Homeowners can take advantage of tax breaks, rebates and a low-interest loan program.

Residents can get a state income tax deduction of 40% of the cost of their solar system the first year it's operational. Then they can get an additional 20% each year for the next three years. The deduction is capped at $5,000 each year and $20,000 total.

Idaho customers of Dominion Energy can also get a $750 rebate for solar water heaters. This includes solar pool heaters as well as indoor water heaters. To qualify, customers must apply on the electric company’s online rebate page, by email or by mail.

Through the Idaho Office of Energy and Mineral Resources, residents can get a solar loan of up to $30,000. Homeowners can choose between three types of loans:

  • 3% interest with a 36-month term
  • 5% interest with a 60-month term
  • 7% interest with an 84-month term

What to know about net metering in Idaho

When your solar system produces more energy than you can use and you don’t have a solar battery to store it in, there’s another option. Through net metering, you can sell the excess energy to your local electric company.

Idaho doesn’t have a statewide net-metering policy, but Avista Utilities, Idaho Falls Power, Idaho Power and Rocky Mountain Power offer net metering for residential customers with systems up to 25 kilowatts (kW). Since there are no state policies, net metering terms will vary from one power company to another.
