Solar Incentives for Belleville Homeowners

Belleville homeowners can combine Illinois Shines REC incentives with Ameren Illinois's $300-per-kW Distributed Generation Rebate and Illinois' solar property tax alternate valuation, filed with the St. Clair County assessor on form PTAX-330. Income-eligible households may qualify for Illinois Solar for All.

Roof First, Then Solar

Solar panels stay on a roof for 25 years or more, so the roof under them should last as long. Through Cox Roofing & Restoration, we can inspect your roof, repair or replace it, and install solar as one coordinated project, which avoids paying to remove and reinstall panels later.

Battery Backup for Storms and Outages

Severe summer storms and winter weather can knock out power across St. Clair County. A home battery keeps essentials like the sump pump, refrigerator, furnace blower, and Wi-Fi running, and lets you use more of your own solar in the evening.
