 In January 2018, Tesla announced, after testing on employees' roofs, that it would begin installing the product on commercial customers' homes "within the next few months".But in July 2019, Greentech Media reported that three years after the announcement of the solar roof tiles, and after having received deposits from interested homeowners, Tesla had connected just a dozen or so solar-integrated roofs to the grid., Tesla was "still tinkering with the product three years after announcing the concept, having done trial installations with two different iterations so far."
