Solar Panel Installation in Flagstaff FAQs
Is solar worth it in Flagstaff?
The sun is strong (about 1,620 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 Arizona 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. Arizona’s own credit (25% of cost, up to $1,000) is separate.

Usually yes, and the utility may need to approve solar and batteries. City of Flagstaff Building Permits handles permits in Flagstaff; see the permit information above.
