Montana's solar-generated electricity was exclusively small-scale residential and business solar installations until 2017, when the state's first utility-scale solar power facilities came online. By late 2019, Montana had six utility-scale solar power farms with a combined generating capacity of 17 megawatts. Montana has a government program to provide technical, planning, and financial assistance for developing community solar projects.
When you install a solar system, 26% of your project expenses apply toward a credit to offset any taxes you owe that year. This federal tax credit is a major incentive to go solar, but it is going to be phased out by 2024.
To be eligible to claim this credit, you must owe federal taxes.
