BillingsSolar Incentives 2026: Rebates, Tax Credits & Net Metering
Billings homeowners stack the 30% federal tax credit and NorthWestern Energy net metering. At 4.5 peak sun hours a day, a home with a $100/month bill (about 714 kWh) needs roughly a 6.6 kW system — 17 panels — and pays back in about 10 years.
Solar Incentives Available in Billings
Solar incentives in Billings come in three layers. First, every homeowner qualifies for the 30% federal Residential Clean Energy Credit on the full installed cost, claimed on IRS Form 5695. Montana does not add a state income tax credit, so the federal credit is the main up-front incentive. Third, NorthWestern Energy sets the local rules for crediting the solar power you export.
NorthWestern Energy offers net metering in Billings, and Montana's high plains deliver strong summer production.
