• Some homeowners with Tesla solar panels said they had been left frustrated as they wait for the company to fixed damaged panels on their roof.
• On August 1, the roof of Briana Greer’s home in Colorado caught fire as she waited for Tesla to send a crew to look at her panels. The company has yet to investigate the situation, she said.
• Greer said that Tesla didn’t properly maintain the panels. Homeowners in states from Maryland to Arizona with Tesla solar panels have also found dealing with Tesla to be frustrating, and they’ve been forced to pay regular fees as their systems have been shut off.
• Current and former Tesla employees said that this is all related to “Project Titan,” a secret program Tesla launched in the summer of 2018 to quietly change out faulty wiring on solar roofs across the country.
• Business Insider sent Tesla an extensive list of claims made by customers and current and former solar employees for this story. Tesla did not reply to repeated requests for comment via phone calls, emails, or text messages.

Briana Greer was out of town when the fire started in her Tesla solar roof panels. Luckily, her neighbors in Louisville, Colorado — a town outside Boulder — were vigilant, and they were able to put out the fire before the fire department arrived.

That was on August 1. The day before, Greer said, Tesla had contacted her to let her know its system had been detecting voltage fluctuations for a couple of days. The company said it would send a crew to check it out on August 8. That was too late.

Greer, an environmental consultant, said she had yet to receive a report explaining why any of this happened.

“They purposely keep a lot of people in the dark. For an energy company, that’s ironic,” Greer told Business Insider in an interview last month.

Tesla did not respond to multiple requests for comment on this article, but a local Fox station in Colorado reported last month that Tesla told it that “its solar panels are safe and very rarely catch fire.” The Fox report also said that Tesla said it was working with Greer’s insurance company.

Tesla has not agreed to let her out of her contract, so Greer set up a GoFundMe to raise funds for an attorney to deal with this matter.

Greer said she believes Tesla was in breach of its agreement with her and Xcel, a third-party electric company that installed her meter and connected Tesla to the grid. Her contract with Tesla, viewed by Business Insider, says Tesla maintains the solar panels according to manufacturer specifications.

Xcel did not respond to a request for comment.

Greer’s panels were made by a solar-panel manufacturer called Trina, whose handbook says its panels should be physically inspected twice a year. Tesla was not doing that, Greer said.

Trina did not respond to a request for comment.

Greer’s contract also said that Tesla should maintain the panels according to state law. In 2017, the year Greer had her panels installed, Colorado adopted the National Electrical Code. But Greer, who provided Business Insider with diagrams of her system, said Tesla did not update her solar panels to code. For example, the NEC 2017 rules require all solar panels to be capable of a rapid shutdown at the module level, and according to Greer, the system that caught fire did not have that.

Tesla did not respond to multiple requests for comment.

In an email dated September 23 and viewed by Business Insider, a Tesla representative told Greer that the company did not have maintenance records “aside from remote monitoring and react
