How to Verify a Nashville Solar Company's License

Q: Is a special solar license required in Tennessee?

Tennessee does not have a separate standalone 'solar-only' license. Instead, rooftop solar installations exceeding $25,000 must be contracted through a state-licensed electrical contractor holding a CE or CMC-E license issued by the Tennessee Board for Licensing Contractors.

Q: What happens if an unlicensed contractor installs solar on my home?

Hiring an unlicensed installer poses severe risks: 1) Metro Nashville Codes and local utilities (NES, MTE) will not approve your electrical inspection, preventing your system from receiving Permission to Operate; 2) If roof leaks or electrical fires occur, homeowner insurance policies may deny claims caused by unpermitted work; 3) Unlicensed contractors have no legal standing to pull permits in Tennessee.

Q: Can an out-of-state solar company work under a local electrician's license?

This practice—sometimes called 'license renting'—is a major red flag. Tennessee contractor law requires the licensed entity to maintain direct supervisory control over the installation. You should always enter into a contract directly with the licensed Tennessee entity performing the work.

Never let an unverified salesperson onto your roof. Here is the exact process to verify state contractor licensing, CE electrical classifications, and insurance coverage in Tennessee.

The 6-Step Tennessee License Verification Checklist

Takes less than two minutes on the official Tennessee Department of Commerce & Insurance portal.

Step 1: Visit verify.tn.gov

Navigate to the official Tennessee Department of Commerce and Insurance licensing portal at verify.tn.gov. Select 'Contractors, Home Improvement, Residential Limited Plumbers' from the profession drop-down menu.

Step 2: Search the Exact Legal Business Name

Search the legal corporate entity name listed on your written contract, not just a marketing trade name. Confirm that the licensee status is listed as 'ACTIVE' with an expiration date in the future.

Step 3: Confirm the Required Classification (CE or CMC-E)

Under Tennessee law, a contractor installing solar must hold a CE (Electrical) classification or CMC-E (Mechanical with Electrical Specialty). A general building contractor (BC) license alone does not authorize high-voltage electrical grid connections.

Step 4: Check the Monetary Limit

Tennessee contractor licenses carry a specific monetary project limit (e.g. $100,000, $500,000, or Unlimited). Ensure the contractor's monetary limit exceeds the total contract value of your solar array and battery project.

Step 5: Verify General Liability & Workers' Compensation Insurance

Confirm that the contractor maintains active Commercial General Liability insurance (minimum $1,000,000 recommended) and active Tennessee Workers' Compensation coverage for all rooftop technicians.

Step 6: Confirm Metro Nashville or County Electrical Permits

Check that the contractor will pull the electrical permit under their own license number. In Davidson County, permits are pulled through the Metro Nashville Codes Department. Never allow a company to ask you to pull a 'homeowner permit'.
