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

Minnesota's solar market grew 45% in 2024 alone, driven by the state's Community Solar program, utility incentives, and the federal Investment Tax Credit. That growth has brought both reputable and questionable solar companies into the state. Understanding what licenses Minnesota requires — and how to verify them — is essential before you commit to a multi-thousand dollar installation.

Does Minnesota require a license for solar installers?

Yes. Solar installation in Minnesota requires a Residential Contractor or Residential Remodeler license from the Department of Labor and Industry (DLI) when the work involves roof attachment or structural modification of a residential property. All electrical work — including inverter installation, panel connections, and utility interconnection — requires a separate license from the Minnesota Board of Electricity. Both licenses must be verified before work begins.

Minnesota's DLI Residential Contractor license applies to construction on one-to-four unit dwellings. Roof-mounted solar installation falls within this scope because it involves attachment to and potential modification of a residential structure. The electrical component requires a separate licensed electrical contractor. Many Minnesota solar companies hold both credentials.

How do you verify a Minnesota solar contractor's license?

Search residential contractor licenses at dli.mn.gov/license-search. Enter the contractor's name or license number. The database shows the license type, status, expiration date, and any disciplinary actions. For the electrical component, verify the electrical contractor's license through the Minnesota Board of Electricity, also accessible through the DLI licensing portal.

Ask the solar company for both license numbers before you sign anything. Verify each independently. A company that holds both a residential contractor license and an electrical contractor license can perform all phases of a solar installation within a single contract. If they subcontract the electrical work, get the subcontractor's license number and verify it directly.

What role does utility approval play in Minnesota solar installation?

Xcel Energy and other Minnesota utilities have specific interconnection requirements that must be met before a solar system can be connected to the grid. Minnesota's Net Metering law allows solar customers to receive credit for excess power exported to the grid, but the system must pass utility inspection and interconnection approval first. A licensed solar contractor will manage the utility interconnection application process.

Xcel Energy's interconnection process requires a licensed electrical contractor to complete the installation and sign off on the electrical work. Projects that are not properly connected by a licensed electrician will not pass Xcel's inspection, meaning the system cannot legally produce power for export. This is a practical enforcement mechanism that makes electrical licensing verification particularly important in Minnesota.

What permits are required for solar installation in Minnesota?

Minnesota requires a building permit for roof-mounted solar installations and an electrical permit for all wiring work. Both are issued by local building departments. Inspections are required at the electrical rough-in stage and at final completion. In Minneapolis, Saint Paul, and other larger cities, the building department has specific solar permitting procedures that licensed contractors should be familiar with.

Minnesota also requires compliance with structural load calculations for roof-mounted systems. A licensed solar installer should conduct a roof assessment and provide load calculations demonstrating the roof can support the panel array. This is both a code requirement and a practical quality check that protects your home.

What insurance should a Minnesota solar contractor carry?

Minnesota DLI requires residential contractors to maintain general liability insurance and workers' compensation. For a solar installation project, require at least $300,000 per occurrence in general liability. Solar installers work at height on rooftops — workers' comp coverage is especially important. Request Certificates of Insurance and verify both policies are active with the insurers before work begins.

Minnesota solar installations have grown 45% recently, and this rapid growth has brought less-established companies into the market. Insurance verification is more important in a fast-growing market, not less.
