What Montana pays for your exported solar power
Export compensation is the single biggest payback lever in 2026. Here is Montana's current rule in plain words, with the official source.
Under Montana's export rules, compensation for surplus power decides the payback - which typically runs 10-14 years on unsubsidized 2026 math.
Installed home solar for Townsend homeowners averages about $2.58 a watt across the U.S. marketplace - roughly $30,960 for a 12 kW system before incentives.
Townsend, Montana has about 2,209 residents, and its solar quotes are built from system size, roof complexity and export rules - not the town name.
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.
The honest 2026 answer for Townsend: solar pays back slower without the 30% credit - paybacks that ran 7-10 years often now run 10-14 - but electricity rates keep rising and hardware is the cheapest it has ever been. The deciding factor is Montana's export compensation, covered in the net metering section.
The 2026 numbers
| System size | Installed price (marketplace avg) | Notes |
|---|---|---|
| 6 kW | $15,480 | Small roof / low usage |
| 8 kW | $20,640 | Typical starter system |
| 10 kW | $25,800 | Family home with AC |
| 12 kW | $30,960 | Large home / EV charging |
| Home battery (optional) | $12,000-$16,000 | Backup power + self-consumption |

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10 years following installation; Montana's former residential alternative energy income tax credit (MCA 15-32-201) was repealed in 2021.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.

Getting Townsend quotes
Same-day contracts are a red flag in this industry. Legitimate MT installers expect you to compare bids, check licenses, and read the interconnection terms. Anyone pressuring you to sign at the kitchen table is pricing in your haste.

Common questions
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 do I check if a solar quote is fair?
Divide the total price by the system's wattage. The U.S. marketplace average is about $2.58 per watt installed; $2.30-3.00 covers most fair quotes depending on roof complexity. Above that, ask exactly what you are paying extra for - in writing.
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.
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.
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.
