How much is the Illinois Shines SREC check for a ComEd homeowner in 2026?
Under the Illinois Shines Adjustable Block Program (Group B — ComEd territory), a typical 8.5 kW to 10 kW residential solar array generates roughly 145 to 170 SRECs over 15 years, paid out as an upfront lump-sum check of $8,500 to $12,500 (after the 5%–10% Approved Vendor fee) within 6–10 months of interconnection.
Can I stack the ComEd $300/kW Smart Inverter Rebate and $300/kWh Battery Rebate?
Yes! Under Illinois CEJA (Climate and Equitable Jobs Act), ComEd residential customers installing a qualifying IEEE 1547-2018 smart inverter receive $300/kW DC on solar PLUS $300/kWh on a paired home battery (e.g., $2,700 for 9 kW solar + $4,290 for a 14.3kWh battery = $6,990 in direct ComEd utility rebates).
