Every solar quote starts with your electric bill — so start here. Enter your average monthly bill and your roof’s sun, and see your numbers run through the same honest math we published in our Homer Glen case study: right-sized system, real ComEd rates, Illinois Shines SRECs, and the net-billing split installers don’t show you. No email required — your numbers stay yours until you ask for quotes.
Ready for the real version of these numbers? Installers will model your actual roof free — get three quotes and make each one show the same split this calculator does.
