On Wednesday, November 11, Tesla rose over 2% in pre-market trading. Elon Musk's solar layout has seen new progress. Recently, he reposted a tweet on engineering progress with three words: "Project Crystal Sun."

The reposted tweets came from tech blogger Sawyer Merritt and aerial photography blogger S.E. Robinson Jr., stating that Tesla has officially launched construction of its large-scale solar manufacturing plant (Project Crystal Sun) near Houston, Texas, in the United States.

Project Crystal Sun involves an investment of up to $10 billion and is expected to be completed in 2028, officially entering commercial operation in the first quarter of 2029. The plant will adopt a vertically integrated solar manufacturing model, producing photovoltaic cells and/or assembled photovoltaic modules, covering multiple production stages and supporting equipment including ingot manufacturing, wafer processing, thin-film deposition, and metallization, involving a vertically integrated production line from silicon material, ingots, and wafers to cells and modules.
