Sunrun Complaints in Illinois — What Homeowners Report (2026)

Quick answer

Sunrun complaints in Illinois most commonly involve solar systems that underperform promised savings in Illinois's variable climate, high-pressure door-to-door sales operations in the Chicago metro and suburban communities, and 20-25 year lease agreements that complicate home sales in competitive Illinois real estate markets. Illinois homeowners have strong protections under the Illinois Consumer Fraud and Deceptive Business Practices Act.

Illinois has become one of Sunrun's most active markets as the state's solar incentives — including the Illinois Shines program and net metering through ComEd and Ameren — have made solar financially attractive for many homeowners. But the aggressive door-to-door sales operations that have moved into Chicagoland, the northern suburbs, and downstate communities have also generated a growing volume of complaints from homeowners who feel they were misled. Here's what Illinois law gives you.

What Illinois Sunrun Customers Are Reporting

Sunrun complaints from Illinois homeowners frequently involve the Illinois Shines program — officially the Adjustable Block Program — which provides Renewable Energy Credits (RECs) that improve solar economics. Illinois homeowners report that sales reps sometimes misrepresented the program's benefits, failed to explain that REC values change with each block, or made specific savings projections that didn't account for the time-limited nature of the REC payments.

Beyond the Illinois Shines issue, the standard pattern of complaints applies: production projections that don't reflect Illinois's actual solar irradiance (particularly in northern Illinois and Chicago's lakefront microclimate), savings that fell short on ComEd or Ameren bills, and long-term leases creating complications when homeowners try to sell in competitive suburban markets like Naperville, Schaumburg, and Orland Park.

The Illinois Consumer Fraud Act

The Illinois Consumer Fraud and Deceptive Business Practices Act (ICFA) is one of the strongest consumer protection statutes in the Midwest. It prohibits unfair or deceptive acts and practices in commerce, including false savings representations, misleading statements about government programs, and undisclosed fees. ICFA allows recovery of actual damages plus attorney's fees, and the Illinois AG actively pursues violations. See the Illinois solar consumer rights guide for more detail.

Illinois also has a Home Repair and Remodeling Act that applies to solar installations on existing homes, and the Illinois Attorney General has previously taken action against solar companies operating in the state. The AG's Consumer Protection Division (illinoisattorneygeneral.gov) is a strong enforcement partner for homeowners with legitimate complaints.

How to Document Your Illinois Sunrun Case

Pull your ComEd or Ameren bills from the 12 months before installation and compare to your post-solar bills. Pull your Sunrun monitoring data and compare actual monthly production to the projected production in your contract. If Illinois Shines RECs were part of your savings projection, request documentation of how the REC value was calculated and whether the current block value matches what was presented. File with the Illinois AG (illinoisattorneygeneral.gov), the ICC (Illinois Commerce Commission) for utility issues, the BBB, and the CFPB.
