How can I tell if my solar contractor is licensed in Wisconsin?
Ask the solar contractor for their Wisconsin Department of Safety and Professional Services (DSPS) license number, then verify it at the board's public lookup. The license must be Active, the class must include Master / Journeyman Electrician / Electrical Contractor, and there must be no open disciplinary actions. Groundcheck (earthmove.io/trust) does this in under 90 seconds and cross-checks court, OSHA, and BBB records simultaneously.
Confirming a solar contractor's license in Wisconsin is a 3-step process. First, get the license number from the contractor — every legitimate solar contractor working in Wisconsin should have one and should give it on request. If they refuse or hedge, walk away. Second, plug it into the Wisconsin Department of Safety and Professional Services (DSPS) public lookup at https://dsps.wi.gov/Pages/Professions/ElectricalContractor/Default.aspx. Third, verify three fields on the lookup result: license status (must read "Active"), expiration date (must be in the future), and disciplinary history (must be clean).
What classification matters: Master / Journeyman Electrician / Electrical Contractor. Wisconsin solar contractors working under any other classification are not authorized for the installs photovoltaic systems, solar thermal systems, battery storage, and related electrical interconnection on residential and commercial buildings you're hiring them for. Confirm the license covers the type of work being performed.
Red flags that the license isn't legitimate or the solar contractor is misrepresenting: the license number doesn't return a result, the lookup returns a different name or business than you were given, the status is "Suspended" or "Inactive," the license is in another contractor's name (the solar contractor is using someone else's license — illegal in every state), or the disciplinary history shows multiple open complaints.
What if the solar contractor won't share their license number? In Wisconsin, every licensed solar contractor is required to display the license number on all advertising, business cards, contracts, and vehicles. If they can't or won't provide it, they're either unlicensed or hiding something.
