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 Madison 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.
