Is there still a solar tax credit for Cascade homeowners in 2026?
The 30% federal credit is gone for 2026 installations. What survives for Cascade: Montana's own incentives and tax treatment - verified against state sources.
The 30% federal solar tax credit ended for installations finished after December 31, 2025 - Cascade systems completed in 2026 get $0 from it.
Installed home solar for Cascade homeowners averages about $2.58 a watt across the U.S. marketplace - roughly $30,960 for a 12 kW system before incentives.
Cascade, Montana has about 579 residents, and its solar quotes are built from system size, roof complexity and export rules - not the town name.
The federal Residential Clean Energy Credit - the 30% one every solar ad still quotes - was repealed by the One Big Beautiful Bill Act signed July 4, 2025. Per the IRS, it is not available for any system placed in service after December 31, 2025, and 'placed in service' means the installation completion date, not the contract date.
If a salesperson in Cascade tells you a 30% federal tax credit applies to your 2026 installation, they are quoting a dead law. What may still exist: Montana's own incentives and tax treatment, listed below, and lease/PPA arrangements where a company claims commercial credits - in which case the credit belongs to them, not you.

Montana rules that decide your payback
| Rule | Montana status |
|---|---|
| Export compensation (net metering) | Montana statute requires utilities to offer net metering to customer-generators whose solar, wind or hydropower facility has a generating capacity of not more than 50 kilowatts (MCA 69-8-103), measuring net electricity each billing period and crediting excess kilowatt-hours on the following month's bill (MCA 69-8-603). |
| State incentive | Nonfossil Energy Generation property tax exemption (MCA 15-6-224) - up to $20,000 of capital investment value on a single-family residential dwelling, exempt for 10 years following installation; Montana's former residential alternative energy income tax credit (MCA 15-32-201) was repealed in 2021. |
| Sales tax on the system | Exempt |
| Property tax on added home value | Excluded |
Montana wipes the slate clean once a year: on January 1, April 1, July 1 or October 1, any remaining unused kilowatt-hour credit accumulated during the previous 12 months 'must be granted to the electricity supplier, without any compensation to the customer-generator' - unlike Wyoming, which at least pays avoided cost, Montana pays nothing, so an oversized system donates its surplus to the utility.

What this means for Cascade roofs
Whether solar still pays in Montana after the federal credit's end comes down to arithmetic, not ideology: installed cost (about $2.58 a watt at the marketplace average), what your utility pays for exports, and how much of your generation you use yourself. High self-consumption - daytime usage, EV charging, batteries - is now the biggest lever.

Getting Cascade quotes
Marketplace platforms collect bids from multiple MT installers against the same spec, which is the only clean way to compare - same roof, same size, different prices. Getting quotes is free and does not commit you to anything; prices come from the installers, never from this site.

Common questions
What happens if my installer goes out of business?
Panel and inverter warranties come from the manufacturers and survive, but the workmanship warranty usually dies with the company. That is a real risk in the post-credit shakeout - prefer installers with years of local history, and get manufacturer-backed workmanship coverage where offered.
What is net metering and why does it decide everything?
It is the rule for how your utility credits electricity you export. Full retail net metering credits exports at the same rate you pay - the grid works like a free battery. Net billing or avoided-cost rules pay far less per exported kWh, which lengthens payback and strengthens the case for a home battery.
Is my roof even suitable for solar?
Three things decide it: orientation (south-facing is best in the U.S., east-west workable), shade (trees or taller buildings across midday hours can sink the math), and roof age (if the shingles have under 10 years left, reroof first - removing and reinstalling panels later costs thousands). Any honest installer assesses all three before quoting a number.
How long do solar panels actually last?
Panels are typically warrantied for 25 years of production and commonly outlive it, losing about 0.5% output per year. Inverters are the component that usually needs replacement - typically once, around year 12-15, at a few thousand dollars.
Is solar still worth it without the federal credit?
It depends mostly on your state's export rules and your daytime usage. Paybacks lengthened by roughly a third when the credit ended, but rising electricity rates and record-cheap hardware keep the math workable in states with decent export compensation - and marginal where exports pay avoided cost only.
