How does Chicago's winter climate affect solar system size and configuration selection?

What red flags should I watch for hiring a solar installer in Chicago?
Check that any Chicago contractor doing solar installation carries both general liability insurance ($1M minimum) and workers' compensation. Request certificates directly from the insurer, not just copies the contractor provides. In Chicago, 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. In Chicago, solar installation on homes over 40 years old should include a contingency line item (10-15% of total). Contractors who guarantee fixed pricing on old-home work either haven't looked closely enough or plan to cut corners when surprises appear.
