Are Solar Panels Worth It in Illinois? (ROI & Home Value)

SBI Editorial DeskUpdated Q1 · 20262 sections

When deciding to transition to renewable energy, the math must make sense. For Illinois homeowners, the answer to "Are solar panels worth it?" is an overwhelming yes, driven by a unique combination of federal incentives, state-level payouts, and rising utility costs.

01

The Rapid Payback Period

Because of the Illinois Shines (SREC) program, the average solar payback period in Illinois is significantly lower than the national average. When you combine the 30% Federal Investment Tax Credit with SREC payouts, most Illinois homeowners break even on their solar investment within 5 to 7 years. After that breakeven point, the electricity your system produces is entirely free, resulting in tens of thousands of dollars in lifetime savings.

02

Increasing Your Home's Value

Data from Zillow and the National Renewable Energy Laboratory (NREL) indicates that homes with solar panels sell for an average of 4.1% more than comparable non-solar homes. In Illinois, you get the benefit of this increased equity without the penalty of higher property taxes, thanks to the state's 100% Special Assessment exemption for solar energy systems.
