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 Glendive homeowners averages about $2.58 a watt across the U.S. marketplace - roughly $30,960 for a 12 kW system before incentives.

Glendive, Montana has about 4,760 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 Glendive: 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.

Montana rules that decide your payback

RuleMontana 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 incentiveNonfossil 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10 years following installation; Montana's former residential alternative energy income tax credit (MCA 15-32-201) was repealed in 2021.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 systemExempt
Property tax on added home valueExcluded

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.

Common questions

Do I need a battery with my solar?

Not necessarily. Under full retail net metering, the grid effectively stores your surplus for free. Batteries earn their $12,000-16,000 price where export rates are low, outages are common, or time-of-use rates make evening self-consumption valuable.

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.

Does solar raise my property taxes?

It depends on the state - many exempt solar's added home value from property tax, others do not, and some exemptions have expiration dates. This guide's state page lists the verified rule and source for your state.

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.
