Permit required
Do you need a permit for Solar Panel Installation in Mower County?
In Minnesota, a Solar Panel Installation requires a building and electrical permit.
Installing solar panels requires a building permit for the roof load and attachment and an electrical permit for the wiring and inverter, plus a utility interconnection agreement (Permission to Operate) before a grid-tied system can be switched on. Many jurisdictions now issue instant permits online through SolarAPP+. Off-grid standalone systems are exempt in some areas. Plans are reviewed under the Statewide code (IRC 2018); apply through Mower County Planning & Zoning before work begins.
