NapervilleSolar Incentives 2026: Rebates, Tax Credits & Net Metering
Naperville homeowners installing in 2026 cannot claim the federal residential credit. What remains is 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 8.9 years.
Solar Incentives Available in Naperville
The federal residential credit does not apply to a Naperville system installed in 2026. Illinois does not add a state income tax credit in this dataset. 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.
