The only requirement to appear on this page is a checked state electrical license, confirmed against the state licensing board as part of our approval process, that's why every listing above shows "License checked." Installers are listed alphabetically by default, not ranked by quality, and no installer pays for placement in that order. LumoWatt does not sell ranking. If paid placement is introduced, it will be clearly labeled and will not change the standard list order. Use the sort dropdown above to re-order the list yourself by years in business or how recently we checked a listing. See our editorial policy and listing standards & verification methodology for the full details.

Wisconsin's outage risk is driven by severe winter weather and summer storms rather than hurricanes: heavy lake-effect snow and ice storms off Lake Michigan create extended outages around Green Bay and the Fox Valley, while Milwaukee and Madison face summer derecho and severe-thunderstorm wind events plus occasional tornado-corridor risk typical of the upper Midwest.
