Licensed Solar Contractor in Montana: How to Verify Before You Hire

April 8, 2026 — 6 min read

Does Montana Require a License for Solar Installation?

Montana does not require a statewide general contractor license for solar installation. However, the electrical work that is central to every solar panel system must be performed by a licensed electrician under the authority of the Montana Board of Electrical Contractors. Local building permits are also required in virtually every jurisdiction across the state.

Montana's solar market has grown significantly as the state pursues renewable energy goals. The Solar Energy Industries Association ranks Montana among states with growing residential solar adoption, with thousands of systems installed in recent years. As more contractors enter the market, understanding who is legally qualified to do the work becomes increasingly important for consumers.

Which Board Licenses Electricians for Solar Work in Montana?

The Montana Board of Electrical Contractors, housed within the Montana Department of Labor and Industry's Business Standards Division, licenses electricians and electrical contractors throughout the state. This board oversees the licensing of journeyman electricians, master electricians, and electrical contractors—all of whom may be involved in solar installation work.

Montana issues several tiers of electrical licenses. A journeyman electrician license allows a person to perform electrical work under supervision. A master electrician license allows independent electrical work and the ability to pull permits. An electrical contractor license is required for a business entity to contract for electrical work. For solar installation, the company you hire should hold a valid electrical contractor license, not just an individual journeyman credential.

The board requires applicants to pass a written examination, demonstrate relevant work experience, and pay licensing fees. Licensed contractors are also subject to ongoing continuing education requirements to maintain their license. This structure is designed to ensure that only qualified professionals are performing electrical work, including the complex DC and AC systems involved in grid-tied solar installations.

How Do You Verify a Solar Contractor's License in Montana?

You can verify an electrician's or electrical contractor's license through the Montana Department of Labor and Industry's online license lookup at boards.bsd.dli.mt.gov/elec. The database allows you to search by name or license number and see current license status, license type, expiration date, and any disciplinary history.

When checking the database, confirm that the license is marked as active and not expired, suspended, or revoked. Also verify that the license type matches the work being performed. A journeyman license is not sufficient for a contractor operating a business—look for an electrical contractor license for the company name.

In addition to the state electrical license, confirm that your contractor is pulling the required local building permits. Montana municipalities and counties each administer their own building permit systems. In Billings, Missoula, Great Falls, Bozeman, and other communities, building permits are mandatory for solar installations. Contact your local building department to confirm permit requirements before work begins.

What Insurance Requirements Apply to Montana Solar Contractors?

Montana does not impose a single statewide bond requirement for general contractors, but the Montana Board of Electrical Contractors requires electrical contractors to carry insurance as a condition of licensure. Reputable solar contractors in Montana should carry general liability insurance and workers' compensation coverage as a matter of course, whether or not a specific minimum is mandated by local rules.

General liability coverage protects homeowners if installation work causes property damage. Workers' compensation coverage protects against liability if a worker is injured on your property. Montana's workers' compensation system is administered through the Montana State Fund, and contractors are required by state law to carry coverage if they have employees. Always request certificates of insurance and verify them with the issuing insurer.

What Are the Risks of Hiring an Unlicensed Solar Contractor in Montana?

Hiring an unlicensed solar contractor in Montana creates significant risks across safety, financial, and legal dimensions. Solar systems involve high-voltage direct current electricity, which presents serious electrocution and fire hazards when installed by unqualified workers. The National Fire Protection Association has identified improper wiring as a leading cause of solar-related electrical fires, with unlicensed work disproportionately represented in incident reports.

Financially, an unpermitted or improperly installed system may not qualify for federal investment tax credits or Montana's state renewable energy tax incentives. Montana offers a residential alternative energy system tax credit, and systems must meet code requirements to qualify. An unlicensed installation that fails inspection could disqualify you from these benefits, costing thousands of dollars.

Additionally, unlicensed contractors frequently operate without adequate insurance. If something goes wrong—a roof leak from improper mounting, a wiring fault causing a fire, or a worker injury—you may have no recourse and face the costs yourself. Montana courts provide limited protection for homeowners who hired unlicensed contractors knowingly.

What Should You Ask a Montana Solar Contractor Before Signing?

Before committing to any solar installation in Montana, ask your contractor to confirm their electrical contractor license number so you can verify it at boards.bsd.dli.mt.gov/elec. Ask whether they will obtain all required local building permits, and who is responsible for scheduling inspections. Request current certificates of general liability and workers' compensation insurance.

Also ask about their experience with Montana utility interconnection requirements. Utilities like NorthWestern Energy have specific interconnection application processes for net metering, and a contractor who is unfamiliar with these requirements could delay your system going live. Experience with the specific utility serving your property is a meaningful differentiator between contractors.
