Montana Solar Market Analysis
Montana's solar economics are increasingly favorable for homeowners. At the current market rate of $3 per watt, a typical residential system costs significantly less than five years ago. Combined with Montana's moderate utility rate of $0.13 per kilowatt-hour, residential solar installations achieve a payback period of 9–12 years after applying the 30% federal investment tax credit. Over a system's 25–30 year lifespan, this translates to substantial long-term savings and energy independence from rate increases.
Montana offers three meaningful incentive programs that enhance solar ROI. The state's net metering policy allows homeowners to receive full retail credit for excess electricity sent back to the grid, effectively doubling the value of peak sun production during Montana's 5.1 average peak sun hours daily. Additionally, the Alternative Energy Revolving Loan Program provides below-market financing for solar projects, while the Property Tax Exemption ensures residential solar installations do not increase property tax assessments. Together, these programs meaningfully reduce the effective cost of going solar.
