A California judge has found Tesla liable for fraud and negligent misrepresentation in a lawsuit involving a $110,000 Solar Roof installation that was never completed and failed to generate electricity. The case involves homeowner Ambrose Conroy, who hired Tesla in 2020 to install a solar-powered roofing system at his property in Rancho Santa Fe, California. The project failed to pass a county inspection, leaving the homeowner with a roof that did not deliver the promised functionality.
The ruling follows repeated disputes over Tesla’s failure to produce documents during the legal proceedings. The company had already accepted liability for breach of contract, breach of warranty and negligence, but continued to contest the fraud and negligent misrepresentation claims. Tesla is now challenging the judge’s decision, meaning the legal dispute is not yet over and the homeowner has not received a final compensation award.
How a $82,210 Solar Roof Project Became a $110,000 Dispute
The dispute began in March 2020, when Conroy signed an agreement with Tesla for a Solar Roof system priced at $82,210. The original contract covered a 13.1-kilowatt installation.
However, after two amendments, the project’s cost increased to approximately $110,000 by February 2021. The revised installation was expected to include an 18.2-kilowatt solar roof and six Tesla Powerwall batteries.
Despite the higher price and expanded scope, the installation was never completed successfully. The roof failed to pass a county inspection and did not generate a single kilowatt-hour of electricity for the homeowner’s property.
Conroy has estimated that repairing the damage could cost more than $2.5 million. Tesla had reportedly offered him $5,000 to settle the dispute in April 2022, but the matter continued through the courts.
What Went Wrong With Tesla’s Solar Roof Installation?
The lawsuit describes a series of problems during the installation process.
According to the complaint, removing the existing roof was expected to take approximately two days but ultimately took two weeks. Parts of the property were allegedly left exposed for extended periods, while scratched and damaged tiles were installed.
The complaint also alleges that some glass tiles shattered around the driveway and lawn, creating safety concerns for the family.
The problems extended beyond the visible roofing materials. Conroy hired an electrical consultant to examine the installation. The consultant reportedly raised concerns about wiring and conduits beneath the tiles, suggesting that the configuration could increase the risk of short circuits and fire during heavy rain.
Tesla’s lawyers disputed the characterisation of the fire risk, according to the reports.
The project also encountered problems during later inspections. In February 2025, Tesla reportedly failed another San Diego County inspection after arriving without the required plans for the venting system.
Why Did the California Judge Find Tesla Liable for Fraud?
The judge’s decision was closely connected to Tesla’s repeated failures to provide documents requested during the discovery process.
Judge Cynthia Freeland had previously sanctioned Tesla twice for failing to produce required material. The company was ordered to pay $15,467.50 in February 2026 and another $13,500 in June.
The court warned that further failures could result in issue sanctions. Such sanctions can allow a judge to treat disputed facts as established when a party fails to comply with discovery obligations.
After Tesla missed another deadline, the court ruled on September 11, 2026, that the company was liable for fraud and negligent misrepresentation.
The missing documents reportedly included Microsoft Teams messages, workplace safety records, communications with San Diego County inspectors and more than 20 internal quality, installation and safety reports.
The judge cited evidence suggesting that Tesla’s failures to provide the material were deliberate. The ruling limited the remaining proceedings on those claims to determining compensatory and punitive damages.
Tesla Had Already Accepted Liability on Three Claims
The lawsuit included five major claims against Tesla.
The company had stipulated to liability on three of them:
- Breach of contract: Tesla accepted liability for failing to fulfil its contractual obligations.
- Breach of warranty: The company accepted liability relating to its warranty obligations.
- Negligence: Tesla accepted liability for negligent conduct connected with the project.
The remaining two claims were fraud and negligent misrepresentation. Tesla continued to contest those claims before the September ruling.
The distinction matters because the judge’s decision did not simply concern a failed installation. It also addressed whether Tesla had misrepresented aspects of its work and whether the company’s conduct during the legal process justified sanctions.
Tesla Challenges the Fraud Ruling
Tesla is continuing to fight the decision.
In an October 29 filing, the company asked the court to freeze the case while it seeks relief from the California Court of Appeal.
Tesla argued that the sanction was unduly punitive, violated its due process rights and effectively amounted to a directed verdict on fraud before a trial.
The company also argued that the discovery dispute was not connected to the fraud claims and that it had since produced the relevant documents. Judge Freeland had already rejected Tesla’s request to reconsider the ruling.
The original November 20 trial date has been vacated. A trial-readiness conference is scheduled for December 4, according to Electrek’s reporting.
The case therefore remains active, and the amount of compensation, if any, that Tesla will ultimately have to pay has not yet been determined.
What the Case Reveals About Tesla’s Solar Roof Business
Tesla introduced its Solar Roof in 2016 as a product designed to combine solar energy generation with the appearance of conventional roofing materials. Instead of placing traditional solar panels on top of a roof, the system used specially designed tiles intended to serve as both roofing material and energy-generating components.
The product attracted attention because it promised to make residential solar installations more visually integrated. However, installing a solar roof requires coordination between roofing work, electrical systems, weatherproofing and inspections.
The Conroy dispute highlights the potential consequences when a complex installation does not meet expectations. It also raises questions about project management, quality control, customer support and the handling of unfinished installations.
The Bigger Picture
The lawsuit comes amid wider scrutiny of Tesla’s Solar Roof business and the challenges of scaling a specialised residential energy product. A solar roofing system is not simply an electricity-generation device; it is part of a home’s primary weather-protection structure. Installation problems can therefore create consequences that extend beyond lost energy production.
For Tesla, the case also carries reputational implications because the dispute involves allegations about internal communications and repeated failures to provide evidence. The final outcome will depend on the ongoing legal proceedings, including Tesla’s appeal efforts and the determination of damages.
Looking Ahead
The next important development is expected to come from the California court proceedings. Tesla is seeking appellate relief from the fraud and negligent misrepresentation ruling, while the homeowner continues to pursue compensation for the failed installation and alleged damage. The December 4 trial-readiness conference is a key scheduled date, although further legal developments could change the timeline.
The case could also become an important reference point for customers considering specialised residential solar installations. For homeowners, it underscores the importance of reviewing contracts, installation milestones, inspection requirements, warranties and dispute-resolution provisions before committing substantial sums to complex home-energy projects.
