Installers, contractors and solar service companies whose service area covers Montana.
Montana already runs mostly on clean power — hydropower and wind supply well over half the state's electricity — and solar is the piece of that mix a homeowner can own outright. Big Sky Country's long summer days make panels produce strongly from spring through fall, and utility-scale solar has arrived too: the 80-megawatt MTSUN project north of Billings, the largest solar facility in the state, has been selling power to NorthWestern Energy since 2022.
Montana's net metering law has been on the books since 1999 and is refreshingly simple: customers of investor-owned utilities can install systems up to 50 kilowatts — far more than a home needs — with no cap on how many customers can take part, and the extra power you generate rolls onto your next bill as kilowatt-hour credits. You even choose which month your 12-month credit cycle starts, so summer sunshine can be banked against winter heating bills. Every electric cooperative in the state has voluntarily adopted net metering as well, so co-op members should ask their co-op for its terms.
State incentives are modest in Montana, so solar here pencils out on sunshine, space, and self-reliance.
