Solar Panel Installation in Idaho Falls FAQs
Is solar worth it in Idaho Falls?
The sun is strong (about 1,330 kWh a year per kW, our estimate), but export credits are low, so solar pays most when sized to what you use at home or paired with a battery. See the Idaho incentives for the state credit.
Is there a federal solar tax credit in 2026?
No. The federal 25D credit ended for expenditures after December 31, 2025. Idaho has no state solar credit, but it allows an income tax deduction of 40 percent of cost in year one and 20 percent for three more years, capped at $5,000 a year.
Do I need a permit for solar panels in Idaho Falls?
Usually yes, and the utility may need to approve solar and batteries. Building Division, City of Idaho Falls handles permits in Idaho Falls; see the permit information above.
