Licensing Requirements for solar panels and other solar power equipment in Wisconsin
There is no specific legislation or registration requirement for solar power equipment in Wisconsin. However, systems must comply with the National Electrical Code (NEC), Institute of Electrical and Electronic Engineers (standard IEEE 1547), and Underwriters Laboratories (UL) safety and equipment standards. You can tell if a product meets these standards by searching for the products on the Californian Energy Commissions list of approved solar panels (and approved solar inverters) because to be on this list equipment must meet the above standards. Customers should note that the interconnection standards in Wisconsin may require you to carry indemnity insurance.
