Chicago has a humid continental climate with cold harsh winters frequently dipping below 0 °F during polar vortex events, and hot humid summers. Lake Michigan moderates extremes but adds spring snow and fall storms. Illinois peak sun hours run 3.9-4.2/day - moderate but workable given the strong incentive stack.

Chicago residential work is heavily unionized for major trades (IBEW Local 134 electrical, UA Local 130 plumbing, Pipefitters Local 597, Carpenters Local 13); union labor drives premium pricing 25-40% above non-union markets Illinois requires solar installers to register with IDFPR; electrical work requires a NICET-certified or local-licensed electrician. NABCEP certification is voluntary but valued by Illinois Shines for SREC program participation.
Battery storage is increasingly attractive in Chicago given grid reliability concerns and Illinois Shines bonus payments for battery-paired systems. The 30% federal credit covers batteries. A 13.5 kWh battery delivers 8-12 hours of essential-loads backup - important during polar vortex outages when grid stress is highest.
Choosing a Chicago contractor: Illinois licensing layers state IDFPR registration with city-specific (especially Chicago) credentials - IDFPR HIC + IDFPR Electrical License + NABCEP voluntary.
