How do SRECs actually save you money?
SRECs (Solar Renewable Energy Credits) are payments you receive for generating clean energy. For a typical Illinois home, that means thousands of dollars back in your pocket.
Starting June 1, residential SRECs increased from 30% to 40%. Add the 10% smart inverter rebate, and homeowners get 50% off total.

What does 50% off solar actually mean for Illinois homeowners? Let's break it down. 👇
A typical 8 kW system costs about $24,000 before incentives.
• 40% SRECs = $9,600 back (paid 12-18 months after install, then quarterly payments for six years)
• **10% smart inverter rebate** = $2,400 back (paid 3-6 months after install)
Total incentives: $12,000
Your net cost after all incentives: $12,000 – half off.
Important to know: These rebates come after installation, not at the time of purchase. But when they arrive, they add up to significant savings.

Why local matters in solar.
When it comes to solar, every state is different. Incentives, utility programs, permitting requirements, weather conditions, and regulations can vary dramatically from one market to another.
That's why working with a local installer makes all the difference.
As one of our customers shared:
"The day of installation was a cakewalk. They came in, communicated exactly what they were going to do, did the work, and I was up and running in no time."
At Windfree Solar, we combine local expertise with a seamless installation experience helping Illinois homeowners and businesses navigate solar with confidence from consultation to commissioning.
