Mosaic Solar Loan Complaints in California — What Borrowers Report (2026)
California Mosaic borrowers report interest capitalization surprises, dealer fee disputes, and loans that survived contractor failures. Here is what the CFPB data shows and what you can do.
Quick answer
Solar Mosaic loan complaints in California center on dealer fees added without disclosure, interest that capitalizes during installation delays, and loan cancellation denials after contractor failures. California homeowners report Mosaic loan balances 20-40% higher than the quoted system price due to undisclosed dealer fees.
Mosaic Solar Loans in California: A Growing Complaint Record
Mosaic is one of the largest solar loan originators in California, financing installations for hundreds of solar contractors across the state. When those contractors fail to deliver — or when loan terms don't match what was promised — Mosaic is the company California borrowers end up fighting.
The CFPB complaint database shows a significant and growing number of Mosaic complaints from California borrowers. California's strong consumer protection laws give borrowers more tools than almost any other state — but using them requires understanding exactly what Mosaic did wrong.
Top Mosaic Complaints from California Borrowers
1. Interest Capitalization During Interconnection
Mosaic loans typically include an interest-only period during installation and interconnection. In California, where interconnection delays with PG&E, SCE, and SDGE can stretch 6-18 months, the amount of interest that capitalizes (gets added to the principal) can be substantial. Many California borrowers report that Mosaic salespeople and solar contractors never explained this clearly.
2. Dealer Fee Opacity
Mosaic charges dealer fees to solar contractors, and those fees are often passed through to borrowers as part of the loan principal. California borrowers report that these fees — which can total thousands of dollars — were not itemized or explained at closing. The result is a loan balance significantly higher than the actual cost of the solar system.
3. NEM 3.0 Impact on Loan Economics
California's transition to NEM 3.0 in April 2023 dramatically reduced the financial benefit of solar for new installations. Many California borrowers with Mosaic loans signed before or during the NEM 3.0 transition report that their solar contractors and Mosaic's financing process never disclosed the impending change — leaving them with loans for systems that will never deliver the promised financial returns.
4. Loans Surviving Contractor Failures
Several solar contractors who originated Mosaic loans in California have since gone bankrupt or ceased operations. California borrowers report that Mosaic continued collecting loan payments even after the installing contractor failed, leaving them with loans for incomplete or unwarranted systems.
California Legal Protections for Mosaic Borrowers
FTC Holder Rule
Any Mosaic loan contract must include an FTC Holder Notice. If it does, you can assert against Mosaic any claims you have against the solar contractor — including fraud, misrepresentation, and failure to deliver. This is your most powerful tool if your contractor went bankrupt or failed to complete your installation.
California CLRA and UCL
California's Consumers Legal Remedies Act and Unfair Competition Law provide strong remedies for deceptive financing practices. If Mosaic failed to disclose material loan terms, you may have claims under both statutes.

Frequently asked questions
What is a Solar Mosaic dealer fee?
A dealer fee is a markup added to your loan by the solar installer. Mosaic allows installers to add fees that inflate your loan balance significantly above the equipment cost. These fees are often not disclosed at the point of sale.
Can I cancel a Solar Mosaic loan in California?
Within 3 days under the FTC rule. California's Home Solicitation Sales Act also provides a 3-day right. After that, California's Consumer Legal Remedies Act (CLRA) and Unfair Competition Law (UCL) may provide grounds if there was misrepresentation.
How do I dispute a Solar Mosaic loan in California?
Send a written dispute to Mosaic at their California address via certified mail. File with the California DFPI (Department of Financial Protection and Innovation), the CFPB, and the California AG.
What happens to my Mosaic loan if my solar installer goes bankrupt?
Your loan obligation continues. However, if the system was never installed or doesn't perform as promised, you may have grounds to dispute the loan under California's CLRA or UCL. Consult a consumer protection attorney.
