If you are thinking about going solar in Illinois, you are not alone. With net metering policies, federal tax credits, and state-level incentives like Illinois Shines, solar panels have become more appealing to homeowners and small businesses across Chicago, Aurora, Naperville, Rockford, and beyond.
At the same time, not every solar installer operates with the same level of care. Some companies have built a reputation for aggressive sales tactics, confusing contracts, long installation delays, or poor customer support after the panels are installed. This article focuses on poorly reviewed solar providers in Illinois based on recurring customer complaints, contract disputes, warranty issues, and service problems reported across public review platforms and consumer forums.
The goal here is not to discourage solar adoption. It is to help you spot warning signs early and avoid costly mistakes that can follow you for 20 to 25 years, which is the typical lifespan of a residential solar system.

Each of the following sections explains why these companies often raise concerns for Illinois homeowners, with practical examples to help you understand what can go wrong.
Sunrun
Sunrun is one of the largest residential solar providers in the United States and has a noticeable presence in Illinois through direct sales and partnerships. Size, however, has not shielded the company from criticism.
A common issue reported by Illinois customers involves confusing pricing structures tied to solar leases and power purchase agreements. Homeowners often believe they are buying a system, only to later realize they signed a long-term agreement with annual rate escalators. Over time, this can make monthly payments higher than expected.
Other recurring complaints include:
- Sales representatives overstating savings based on ideal sun exposure rather than actual roof conditions
- Delays between contract signing and system installation
- Difficulty reaching customer support after installation
In Illinois winters, snow load and shading matter. Some homeowners report that system output projections did not account for seasonal weather patterns common in the Midwest, resulting in lower-than-expected production.
ADT Solar
ADT Solar entered the market after acquiring Sunpro Solar, bringing brand recognition but also inherited operational challenges. In Illinois, complaints often revolve around mismatched expectations.
Many customers say they were promised near-total electric bill elimination, only to discover their system offset a smaller portion of usage. This is especially problematic in homes with electric heating or older insulation common in parts of Illinois.
Key concerns include:
- Sales claims that conflict with final system capacity
- Long wait times for inspections and utility approvals
- Limited follow-up once installation is complete
Illinois utilities require strict interconnection approvals. Delays in paperwork submission have reportedly slowed system activation for some ADT Solar customers, leaving panels idle for weeks or months.
Vivint Solar
Vivint Solar, now operating under the Sunrun umbrella in many regions, still carries a history of customer dissatisfaction in Illinois.
The most frequent complaints involve billing disputes and contract confusion. Customers have reported being billed before systems were fully operational or receiving unclear explanations of escalator clauses in long-term agreements.
Other issues include:
- Installation timelines stretching beyond initial estimates
- Inconsistent communication during the permitting process
- Challenges canceling contracts within allowed periods
Illinois homeowners who moved or refinanced their homes sometimes faced complications transferring Vivint-related agreements, which added stress during real estate transactions.
Blue Raven Solar
Blue Raven Solar markets itself as customer-focused, but Illinois reviews tell a more mixed story.
Financing is a common sticking point. Some customers report confusion around loan terms, interest rates, and total system cost once incentives are applied. In Illinois, where Solar Renewable Energy Credits can significantly affect pricing, lack of clarity can lead to frustration.
Reported concerns include:
- Savings estimates that did not reflect actual energy usage
- Delays related to local permitting offices
- Limited responsiveness once payments began
While some customers report positive experiences, the inconsistency in outcomes raises caution for homeowners expecting a smooth, hands-off process.
Titan Solar Power
Titan Solar Power has expanded rapidly across multiple states, including Illinois, often relying on third-party sales dealers. This business model has led to uneven customer experiences.
One common issue involves subcontracted installation crews. Quality can vary depending on who performs the work, which impacts roof integrity and system reliability.
Illinois customers have noted:
- Roof damage due to improper mounting techniques
- Missed installation deadlines
- Slow resolution of system errors
Given Illinois’ freeze-thaw cycles, installation quality matters. Poor sealing or mounting can lead to leaks that appear months after installation, especially during spring thaws.
Trinity Solar
Trinity Solar has operated for years and maintains a strong East Coast presence, but Illinois homeowners have reported communication challenges.
Design accuracy is a recurring concern. Some customers say panel layouts did not match initial proposals, leading to reduced production or aesthetic issues.
Other reported problems include:
- Misalignment between sales and engineering teams
- Delays correcting design errors
- Unclear warranty responsibilities
In Illinois, roof pitch and orientation vary widely between older homes and new developments. Errors during system planning can significantly affect long-term output.
SunPower by Legacy Dealers
SunPower panels are known for efficiency, but experiences vary widely depending on the local dealer. In Illinois, some Legacy-affiliated installers have received criticism despite offering premium equipment.
Common complaints focus on cost versus service quality. Homeowners paying higher prices expect smoother project management and faster support, which has not always happened.
Issues reported include:
- Extended wait times for service calls
- Confusion around manufacturer versus installer warranties
- Delayed system monitoring setup
When problems arise, customers may feel caught between the panel manufacturer and the local installer, each pointing responsibility elsewhere.
Freedom Forever
Freedom Forever operates as an installation partner for various sales organizations, including some national solar brands. This setup can create accountability gaps.
Illinois homeowners often report that once installation is finished, communication drops sharply. Activation delays tied to inspections and utility approvals are common themes.
Other issues include:
- Incomplete documentation submissions
- Delays in turning systems on
- Difficulty scheduling service visits
In some cases, panels were installed correctly but sat unused due to missing paperwork, costing homeowners months of potential energy savings.
Momentum Solar
Momentum Solar is known for aggressive door-to-door sales, and Illinois is no exception. While some customers appreciate the convenience, others report feeling pressured into quick decisions.
Concerns often involve:
- Sales presentations that downplay long-term costs
- Limited explanation of financing terms
- Delays during peak installation seasons
Illinois summers are short, and missed installation windows can push projects into winter, when snow and freezing temperatures slow progress even further.
PowerHome Solar (Pink Energy Legacy Issues)
PowerHome Solar, later rebranded as Pink Energy, left a trail of unresolved issues that still affect some Illinois homeowners.
Customers have reported system failures, unfulfilled warranties, and difficulty obtaining repairs after company closures and restructurings.
Key issues include:
- Non-functional systems with no service support
- Confusion over warranty ownership
- Financial losses tied to unfinished projects
Although the company no longer operates under the same name, the impact on affected Illinois homeowners remains a cautionary tale about vetting company stability.

Conclusion
Solar energy can be a smart long-term investment in Illinois, especially with available incentives and rising electricity costs. Still, choosing the wrong installer can turn that investment into a financial burden that lasts decades.
The companies discussed above are legitimate businesses, but repeated customer complaints point to patterns that deserve attention. Common red flags include unclear contracts, inflated savings claims, rushed sales tactics, and weak post-install support.
If you are planning to go solar in Illinois, take your time. Read contracts line by line. Ask how system output estimates are calculated for Midwest weather. Confirm who handles permits, inspections, and utility coordination. Most importantly, check how service issues are handled after installation, not just before you sign.
Solar should reduce stress and monthly costs, not create new ones. A careful approach upfront can save you years of frustration down the road.
Frequently Asked Questions
How can I verify whether a solar company’s savings estimate is realistic for my Illinois home?
A realistic estimate should be based on your actual electric bills from the past 12 months, not an average household profile. In Illinois, seasonal usage swings matter because winters are long and solar output drops during shorter days. Ask the installer to show how they calculated system size, assumed panel production during winter months, and accounted for shading from trees or nearby buildings. If the estimate only shows best-case scenarios, that is a sign to slow down.
What happens if a solar company goes out of business while my system is under warranty?
This depends on how the warranties are structured. Equipment warranties usually come from the panel or inverter manufacturer, while labor warranties come from the installer. If the installer shuts down, labor coverage often disappears unless it was backed by a third party. Before signing, ask who services the system if the installer is no longer operating and whether monitoring access remains active without the original provider.
Are Illinois solar incentives applied automatically, or do I have to manage them myself?
In many cases, the installer handles incentive paperwork, but that is not always guaranteed. Programs like Illinois Shines and net metering require accurate documentation and timely submissions. If paperwork is delayed or incomplete, incentives can be reduced or missed entirely. Always confirm in writing who is responsible for filings, deadlines, and follow-up with the utility and state program administrators.
Can a poorly installed solar system affect my home insurance or roof warranty?
Yes, it can. Improper mounting can void roof warranties and raise concerns with home insurance providers, especially if leaks or structural issues develop. Illinois weather adds extra stress due to snow load and freeze-thaw cycles. Before installation, ask whether the installer coordinates with roofing manufacturers and whether proof of insurance and workmanship coverage is provided.
What should I do if my solar system is installed but not producing power?
First, confirm whether the system has received final inspection approval and utility permission to operate. In Illinois, systems often sit idle due to missing inspections or incomplete interconnection paperwork. If approvals are complete, check whether monitoring is active and inverters are online. If the installer is unresponsive, document all communication and contact your utility to verify grid connection status.
