Billings and Bozeman homeowners in Big Sky Country face brutal winter heating costs stretching from November through March.
If you’ve been researching solar tax credits 2026, here’s what you need to know upfront: the rules changed significantly, but the savings opportunity for smart homeowners is still very real.
The Residential Clean Energy Credit (Section 25D), the homeowner 30% federal tax credit, expired on December 31, 2025. Homeowners purchasing or financing a solar system in 2026 cannot claim it on a personal tax return.
However, solar companies using third-party ownership models still access the commercial federal solar tax credit 2026 (Section 48E, active through 2027) and pass those savings directly to homeowners through lower monthly rates.
Combine that with powerful state incentives, and 2026 remains one of the smartest years to go solar if you approach it correctly.
What Changed with Solar Tax Credits in 2026?
The One Big Beautiful Bill Act, signed in July 2025, accelerated the sunset of the residential solar credit. Starting January 1, 2026:
- Homeowners cannot file IRS Form 5695 for a new solar installation.
- The direct solar panel tax deduction for residential purchases no longer exists.
- The commercial energy credit, Section 48E, remains active through 2027.
This shift doesn’t eliminate solar savings; it changes how you structure the deal. Understanding this distinction is the difference between a smart solar investment and a frustrating surprise at tax time.

Third-Party Ownership: How Homeowners Still Benefit

- The solar company owns the system installed on your roof.
- They claim the Section 48E commercial credit and factor those savings into your contract rate.
- You pay a fixed, lower monthly rate for the power your system produces, often well below your current utility bill.
- No large upfront investment is required in many cases.

FAQs about Solar Tax Credit
What is the federal solar tax credit for 2026?
The residential federal solar tax credit (Section 25D) expired on December 31, 2025, meaning homeowners who purchase or finance a solar system in 2026 cannot claim a personal federal tax credit.
However, the commercial solar credit (Section 48E) remains active through 2027. Solar companies using lease or PPA models still access this credit and pass those savings to homeowners through reduced monthly energy rates.
How much can solar panels save me?
Even without the residential federal credit, most Montana homeowners save $800–$1,500 annually through reduced utility bills, fixed-rate solar agreements, and available state incentives.
Over a 25-year system lifespan, total energy savings can realistically reach $20,000–$37,500, before accounting for Montana’s 10-year property tax exemption or the long-term protection against rising utility rates.
Do solar panels still work during snowy Montana winters?
Yes! It is a common misconception that solar requires hot weather. In fact, solar panels actually operate more efficiently in cold temperatures. While Billings and Bozeman experience heavy snowfall, Montana still averages 180–205 sunny days per year.
On cold, clear winter days, your panels will produce excellent power. Furthermore, because solar panels are installed at an angle and generate their own slight heat, snow typically slides right off, allowing your system to quickly resume generating electricity.
