Solar Panel Installation in Rexburg FAQs
Is solar worth it in Rexburg?
The sun is strong (about 1,290 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 Rexburg?
Usually yes, and the utility may need to approve solar and batteries. Building Department, City of Rexburg handles permits in Rexburg; see the permit information above.
