For a standard single-family home in Illinois requiring an 8kW system, the gross cost typically ranges between $24,000 and $29,000. Let's break down the actual net cost after applying the 30% federal tax credit.

*CRITICAL NOTE: An 8kW system in Illinois will generate massive SREC payouts through the Illinois Shines program. These payouts often amount to $6,000 to $10,000+ depending on the utility zone and system size, radically driving down the final lifetime cost of your system to pennies on the dollar.
