Solar Incentives in Idaho (2026)
Idaho's generous state tax deduction helps offset its low electricity rates for a workable payback. Here are Idaho's 2026 solar incentives, electricity rates, net metering rules and typical payback — plus tools to run your own numbers.

Is solar worth it in Idaho?
Idaho's generous state tax deduction helps offset its low electricity rates for a workable payback. At an average residential rate of about ~11¢/kWh, every kilowatt-hour your panels produce is a kilowatt-hour you don't buy from the utility — and that avoided cost is what drives your payback. Combined with good sunshine, a standard 7 kW system in Idaho generally pays for itself in 15–19 years with no federal tax credit, then delivers a decade or more of nearly free power.
To see your own number rather than this state average, plug your actual electric bill into the Solar Payback Calculator. If you're weighing how to pay, the Financing Calculator compares cash, loan and lease side by side.
Idaho solar incentives in 2026
The federal 30% credit ended for systems installed after Dec 31, 2025, so Idaho's own incentives now carry more weight:
- Residential Alternative Energy Tax Deduction: deduct up to 40% of cost the first year (capped), then 20%/yr
- Net metering through Idaho Power and others
- Low install costs in a growing market
State programs change frequently. Always confirm current details and eligibility on the DSIRE database and with a licensed local installer before you sign anything.
Buying vs leasing solar in Idaho in 2026
With the homeowner credit gone, the math has shifted. If you buy (cash or loan), you now pay the full installed price — about $21,000 for a typical 7 kW system — minus only Idaho state and utility incentives. If you lease or sign a PPA, the company that owns the panels may still claim a commercial clean-energy credit (Section 48E) for projects that begin construction by July 4, 2026 or are placed in service by the end of 2027, and some pass part of that saving to you as a lower monthly rate. Get one cash quote and one lease/PPA quote, then compare 25-year cost in the Lease vs Buy Calculator.
Net metering in Idaho
Idaho uses Net metering (utility-specific). Net metering is the second-biggest factor in your solar economics after your electricity rate, because it determines how much credit you earn for the excess power your panels send back to the grid. Generous, full-retail net metering shortens payback; reduced export rates lengthen it and increase the value of pairing your system with a home battery.
