State lawmaker says installation time and costs affect buy-in. Author: Ron Plants Updated: 9:04 PM EDT July 13, 2021 BUFFALO, N.Y. — Tesla CEO Elon Musk has wrapped up his testimony in a civil trial against him in Chancery Court in Wilmington Delaware where the firm is incorporated. That civil case is tied to Tesla's 2016 purchase of the Solar City firm which included its South Buffalo plant that the state and taxpayers funded for more than $800 million. Whatever the judge decides in that case, the Buffalo plant and solar roof and panel production is still a question mark. Tesla does not speak with the media. But they do answer to a local state senator who sits on the Senate Commerce, Economic Development and Small Business Committee. So with the firm's much touted solar roof project, Senator Sean Ryan of Buffalo has some questions about their product focus and implementation.
