ComEd Smart Inverter Rebate

The ComEd Smart Inverter Rebate is a rebate tracked in the federal DSIRE database as one of Illinois's solar policy levers. Eligibility is scoped to residential customers, with a stated benefit of Up to $300. The program does not carry a scheduled sunset in DSIRE, though appropriations and enabling legislation can still be revised year to year. Like every state-level incentive, it is designed to stack on top of the federal 30% Investment Tax Credit rather than replace it.

Layered onto Illinois's underlying economics, this matters more than it might look in isolation. The state averages 4.3 kWh/m²/day of usable sunlight and residential rates of 16.5¢/kWh, producing an estimated 7,534 kWh/year and $1,243 in annual utility offset on a typical 6kW system costing $17,400. Without incentives that baseline already implies a 14-year simple payback — every dollar this rebate delivers compresses that payback further and improves 25-year net returns, currently modeled at roughly $13,675 before accounting for the ComEd Smart Inverter Rebate itself.

This program is not the only option. Illinois has 5 solar incentive programs indexed in DSIRE, including adjacent options like IL Solar Property Tax Exemption, IL Net Metering, Illinois Shines (Adjustable Block Program). The state's net metering policy is classified as full, which governs how excess generation is credited and often determines whether a given program is worth claiming for a specific household. Before applying, verify current terms on the official program page, confirm your utility participates, and consult a qualified tax professional about how state credits interact with the federal ITC on your return.
