NapervilleSolar Incentives 2026: Rebates, Tax Credits & Net Metering
Naperville homeowners stack the 30% federal tax credit and ComEd / Naperville Electric net metering. At 4.4 peak sun hours a day, a home with a $115/month bill (about 821 kWh) needs roughly a 7.8 kW system — 20 panels — and pays back in about 4.7 years.
Solar Incentives Available in Naperville
Solar incentives in Naperville come in three layers. First, every homeowner qualifies for the 30% federal Residential Clean Energy Credit on the full installed cost, claimed on IRS Form 5695. Illinois does not add a state income tax credit, so the federal credit is the main up-front incentive. Third, ComEd / Naperville Electric sets the local rules for crediting the solar power you export.
Naperville runs a municipal electric utility, so its net metering and Illinois Shines SREC participation differ from neighboring ComEd towns.
