A U.S. federal company is contemplating as proof a former Tesla worker’s criticism about how the corporate managed and communicated about hearth dangers and defects in its photo voltaic installations, CNBC has discovered from paperwork acquired by a Freedom of Data Act request.

The U.S. Shopper Product Security Fee (CPSC) is continuing with an investigation, and has additionally interviewed the previous Tesla worker who filed the criticism in spring 2019, Steven Henkes, who was then a Tesla Photo voltaic Subject High quality Supervisor.

Henkes believes “there continues to be an actual menace of fires as a result of serial defects within the Tesla installations,” in line with an emailed assertion from his lawyer, Robert Wallace. “The shoppers haven’t been adequately knowledgeable of the dangers,” the assertion says.

Tesla entered the photo voltaic enterprise in late 2016 when it acquired SolarCity for $2.6 billion. Amongst different issues, Tesla Vitality (previously SolarCity) installs rooftop photovoltaics, ground-based and carport photo voltaic vitality techniques.

Whereas Tesla doesn’t get away income from photo voltaic by itself, “vitality era and storage” represented solely 6% the corporate’s complete income in 2020, however grew by 30% from final 12 months, in line with its 2020 end-of-year financial filing. On a January 27 earnings name, Musk instructed analysts: “We’re placing loads of consideration on photo voltaic and it’s rising quickly. So I believe it won’t be lengthy earlier than Tesla is by far the market chief in photo voltaic.”

Tesla’s techniques have been put in at houses together with navy housing models at Fort Bliss and different bases, colleges within the L.A. unified school district, and industrial services together with Walmart shops and Amazon warehouses.

As CNBC beforehand reported, Tesla photo voltaic installations have beforehand caught fire. In Aug. 2019, Walmart sued Tesla for negligence after photo voltaic rooftop techniques put in by Tesla Vitality ignited at a number of Walmart areas.

In court docket filings, Walmart stated that Tesla did not correctly monitor, restore and preserve these techniques, even after the fires occurred. The fires precipitated important injury and defective techniques posed severe dangers to workers, clients and enterprise, in line with Walmart’s criticism then.

On November 5, 2019, the businesses issued a joint assertion saying they had been trying ahead to “a secure re-energization of our sustainable vitality techniques.” The precise phrases of the businesses’ settlement — and prices to Tesla — have by no means been disclosed.

Neither firm instantly responded to requests for remark in regards to the CPSC investigation.

The danger of fires remains to be very low in photo voltaic photovoltaics, whether or not residence or bigger scale techniques, in line with Greg Sellers, CEO of a photo voltaic upkeep and repairs enterprise in Morgan Hill, California. Analysis by Fraunhofer Institute for Solar Energy Systems backs up his commentary from the sector.

With out commenting on Tesla particularly, Sellers defined: “For these of us within the restore and security aspect, any incident is simply too many. Fires are nonetheless very uncommon. That is why they get a lot publicity after they do occur.” He says it is typically extra probably a hearth can be brought on by a failed set up follow than a part failure. And he notes that photo voltaic installers have been getting higher and higher as these techniques proliferate.

Public security concern

CNBC requested the CPSC — a federal company tasked with “defending shoppers from merchandise that pose a hearth, electrical, chemical, or mechanical hazard” – for a replica of Henkes’ full criticism after it was referenced in his lawsuit within the fourth quarter of 2020.

She wrote, “The data you requested are from the CPSC’s Workplace of Compliance and Subject Investigation’s lively legislation enforcement investigatory recordsdata.”

Henkes declined to talk with CNBC straight, however answered some questions by e mail by his legal professional Robert Wallace.

He confirmed that the CPSC had interviewed Henkes and requested the previous Tesla worker to submit further supplies to the company. The objects Henkes submitted to the feds in a “CP-15” criticism included:

·      failure evaluation studies from a third-party engineering agency

·      inner assembly minutes, studies and emails

·      buyer notification examples

·      photographs of thermal occasions linked to buyer homes

·      assembly minutes and shows pertaining to a provider named Amphenol and Tesla

Henkes needs Tesla to “rethink its readability with the shopper,” his legal professional stated on his behalf. The previous worker was engaged on implementing “a everlasting countermeasure” for the problems he discovered earlier than he was fired, the legal professional added. Nevertheless, Henkes alleges that he was “frequently thwarted after which fired for persevering with to work on behalf of public security” on the finish of his tenure at Tesla.

One other former Tesla photo voltaic worker, who requested to stay un-named as a result of he nonetheless works within the photo voltaic business, corroborated a lot of Henkes’ claims from the general public lawsuit.

Particularly, this particular person stated that a lot of Tesla’s photo voltaic system installations, particularly these together with sure roof racking elements and Amphenol H4 connectors, pose a big hearth threat and that Tesla’s remediation or modification efforts haven’t been clear or efficient. In addition they stated the corporate nonetheless hasn’t mounted or eliminated all of the techniques with recognized hearth dangers.

Tesla used to outsource remediation efforts and upkeep of its ageing photo voltaic fleet, however is now cancelling a minimum of a few of these contracts and bringing the method again in-house, in line with this former worker.
