Illinois Solar Information

Illinois isn't a bad state for solar but far from the strongest. There is a state tax credit that reduces your income tax. Along with basically wiping out your state income tax although not required by the state the three major utilities servicing all of Illinois offer net metering. As always in Illinois you are entitled to the 30% federal tax credit.

I am claiming the 30% Federal Tax Credit (ends 2019) i

When you install your solar system, 30% of your project expenses apply toward a credit to offset any taxes you owe that year. This federal tax credit is a major incentive to go solar, but it is being phased out by 2022.

Most people are eligible to claim this credit (you must owe federal taxes to be eligible).
