Tesla has solely put in 3,000 of its Photo voltaic Roof programs within the U.S. since touting the expertise seven years in the past, in response to new analysis from Wooden Mackenzie.

That set up price falls nicely shy of Tesla’s steering and ambitions for what it beforehand referred to as its “photo voltaic glass” roof tiles. Wooden Mackenzie notes that in late 2019 the corporate mentioned it was aiming to fabricate 1,000 Photo voltaic Roofs weekly, and to put in 1,000 per week within the first half of 2020.

The report presents the most recent glimpse into Tesla CEO Elon Musk’s battle to combine a photo voltaic vitality enterprise into his electrical automobile firm following the 2016 acquisition of SolarCity, a photo voltaic installer based and run by his cousins Peter and Lyndon Rive together with his assist.

Common weekly Tesla Photo voltaic Roof installations reached simply 21 in 2022, Wooden Mackenzie mentioned. Tesla hit a excessive of 32 common weekly installations within the U.S. within the first quarter of final yr, in response to the examine.

Musk first promoted a shingle-style photo voltaic panel in October 2016, as he was attempting to garner shareholder enthusiasm for Tesla’s $2.6 billion buy of SolarCity. The shingle he confirmed at a advertising and marketing occasion was not even a working prototype, it was later revealed. Musk had invested important capital in SolarCity, and served as board chairman whereas additionally helming Tesla and SpaceX.

A bunch of Tesla shareholders finally sued Tesla and Musk over the deal. Final yr, the Delaware Courtroom of Chancery dominated in favor of Musk in a bench trial. However the shareholders’ attorneys on Wednesday made their opening arguments in pursuit of an enchantment in Delaware Supreme Courtroom.

Shareholders alleged that Tesla’s SolarCity buy amounted to a bailout and was pushed by Musk as a result of his private wealth and fame had been at stake. Musk has denied that he pressured the Tesla board to undergo with the SolarCity deal. Had he misplaced, Musk may have been compelled to pay upwards of $2 billion, CNBC beforehand reported.

Whereas Tesla’s Photo voltaic Roof effort has struggled, the corporate’s conventional photo voltaic panels have seen some improved traction available in the market.

The standard solar-panel installations shrank significantly from 2016 to 2020, however volumes have been on the rise together with broader development within the residential photo voltaic business, Mackenzie Wooden researchers instructed CNBC in an e-mail. Tesla put in conventional photo voltaic panel programs with an influence producing capability of 156 megawatts in 2021, and 248 megawatts in 2022, the researchers mentioned.

The three,000 Photo voltaic Roof programs which can be put in within the U.S. have an estimated capability of round 30 megawatts.

Whereas Tesla meant to fabricate all of its photo voltaic roof tiles initially, it has as a substitute procured photovoltaic glass from Chinese language provider, Almaden. Residential roofing firm GAF Vitality started manufacturing and promoting a competing photo voltaic shingle to residential roofers in 2022.

The Tesla Photo voltaic Roof commanded lower than .03% of the roughly 5 million new rooftops constructed within the U.S. in 2022, in response to Wooden Mackenzie.

Tesla did not reply to a request for remark.
