Mounting Complaints & many names one problem around SUNCO (now ATTYX) / Solar Mosaic LLC and SolarServicingLLC

As the U.S. solar industry expands, companies promising energy savings and easy financing have surged in popularity. But behind the marketing, a growing body of complaints, legal disputes, and consumer frustration is raising serious concerns about companies like SUNCO (now ATTYX) / Solar Mosaic LLC—now tied closely to SolarServicingLLC following financial restructuring.

A Flood of Complaints

Public complaint data paints a troubling picture.

According to the Better Business Bureau, SolarServicingLLC has accumulated dozens of complaints in recent years, many involving delays, billing disputes, and lack of communication. 

Customers report:

• Being unable to refinance homes due to solar-related liens
• Weeks or months of delays with little to no updates
• Difficulty reaching knowledgeable representatives

One complaint describes a homeowner waiting over 45 business days for a routine request, with no timeline provided and no meaningful updates. 

Others allege far more serious issues—such as loans remaining active even after project cancellations, leaving consumers with tens of thousands of dollars in debt for systems they never received. 

Billing Issues and Unauthorized Charges

Complaints tied to Solar Mosaic (the predecessor company) and SolarServicingLLC frequently center on financial irregularities.

Records show allegations of:

• Unauthorized withdrawals from bank accounts
• Duplicate or inflated payments
• Unexpected increases in monthly loan amounts

In one case, a customer claimed the company withdrew triple the required payment and refused to issue a refund, instead applying the funds to loan principal. 

Another complaint alleges being charged for solar panels that were never activated or usable, with repeated attempts to resolve the issue ignored. 

Allegations of Misleading Sales Practices

Consumer complaints also raise concerns about how these solar financing agreements are presented.

Some borrowers claim they were led to believe programs were:

• “Free government programs”
• Low-risk or savings-guaranteed
• Clearly explained—when in reality, large loans were attached

One complaint alleges over $166,000 in debt was incurred under terms the customer says were not properly disclosed. 

Others report discrepancies between promised and actual monthly payments, contributing to long-term financial strain.

Bankruptcy Fallout and Legal Gray Areas

The situation appears to have worsened following Solar Mosaic’s financial troubles and restructuring.

Customers frequently reference confusion after:

• The company’s bankruptcy proceedings
• Loan servicing transfers to SolarServicingLLC
• Disputes between lenders and installers over funds

On forums like Reddit, users describe being caught in what one called a “bankruptcy standoff”, where loans remained active despite project cancellations and unclear responsibility between companies. 

“I noticed an outstanding loan balance… after I cancelled the project,” one user wrote, describing a situation that led them to consider legal action. 

Lawsuits and Legal Concerns

While not every complaint results in litigation, there is evidence of legal disputes tied to the broader ecosystem surrounding Mosaic.

In at least one California appellate case discussed publicly, courts examined issues involving:

• Questionable sales practices
• Disputes over contract validity
• Attempts to move cases into arbitration

These types of cases suggest ongoing legal scrutiny around how solar financing agreements are formed and enforced. 

A Breakdown in Trust

Taken together, the complaints highlight recurring themes:

• Poor communication
• Billing and loan servicing disputes
• Confusion after corporate transitions
• Allegations of misleading sales tactics

Solar financing is inherently complex, but critics argue that complexity is being compounded by unclear practices and weak customer support.

BEWARE

SUNCO (now ATTYX) / Solar Mosaic LLC and SolarServicingLLC operate in a high-growth, high-stakes industry where trust is essential. Yet the volume and consistency of complaints—from billing issues to unresolved loans—suggest systemic problems that go beyond isolated incidents.

While some customers may have positive experiences, the documented pattern of disputes, financial complaints, and legal concerns signals a need for caution.
