What red flags should I watch for hiring a solar installer in Wheaton?
Check that any Wheaton contractor doing solar installation carries both general liability insurance ($1M minimum) and workers' compensation.

In Wheaton, verify your solar installation contractor pulls the permit themselves — never pull it in your own name. If they ask you to pull the permit, they may not be properly licensed to do the work.
