Montana FAQ
Does Montana have a solar tax credit in 2026?
Montana does not offer a state income tax credit for residential solar in 2026. The federal residential credit (Section 25D) expired Dec 31, 2025 and does not apply to 2026 installations.
What is net metering like in Montana?
Montana uses full retail net metering. This means every exported kWh is credited at your retail rate — the most favorable setup for solar.
Is solar worth it in Montana after the federal credit ended?
At a typical 2.85/W installed cost and 13.6¢/kWh electricity, a 6 kW system in Montana has an estimated payback of about 15.4 years (rank #31 of 51 states). That is a long payback — solar is hard to justify unless strong state incentives apply to your situation.
