Tesla (TSLA) Breaks Ground on $10 Billion Crystal Sun Solar Factory

$10 Billion Solar Plant Rises Near Houston

Tesla (TSLA) has broken ground on Crystal Sun, a $10 billion solar factory near Houston, Texas, adding another multi-billion-dollar commitment whose output reaches shareholders years after the spending begins. The plant is designed to cover the full manufacturing chain in one facility, from silicon ingots and wafers through coating, metallization and final cell testing, so Tesla would not rely on imported cells for the panels it sells. Construction is expected to finish in 2028, according to a Tesla investor, a schedule the company itself has not confirmed. Commercial production would follow in the first quarter of 2029.

Progress on the ground is already visible: a local observer who visited the site in Fort Bend County, southwest of Houston, found cleared land and leveling work underway, consistent with an active construction start rather than a paper announcement. Tesla's state filing records 9,712 full-time jobs tied to the project, according to Manufacturing Dive. Elon Musk marked the milestone on X, posting a construction update under the project's name. No capacity target, cost breakdown or hiring timeline has been made public, and the $10 billion figure remains the only cost estimate attached to the project so far. The projected economic footprint is large: estimates attached to the plan put its potential addition at about $107 billion to Texas gross domestic product and roughly $6.4 billion in state and local taxes. Musk publicised the buildout under the Crystal Sun name alone, giving the project a standalone identity in his portfolio of industrial bets. Earlier this year he floated a goal of 100 gigawatts of US solar cell output per year, and Crystal Sun is sized as a first step toward it.

Powering Terafab, Without Chinese Cells

Crystal Sun is the second leg of a two-part industrial plan that now spans chips and power. It follows Terafab, the AI chip plant Musk announced in Austin, which Intel has since joined. Intel's participation makes Terafab a shared venture rather than a purely Tesla project, a detail that shapes how the capital burden is shared. On Tesla's July earnings call, Musk connected the solar buildout to rising electricity demand from artificial intelligence and electrification, framing Crystal Sun as the power-supply answer to the compute capacity Terafab is meant to produce.

The competitive problem he is aiming at is cost. Musk has said Chinese producers currently make solar cells at very low cost, and a fully domestic line from raw silicon to finished panel is his answer. The capital commitments are piling up: Terafab alone has been pitched as the most valuable building on Earth, and Crystal Sun adds another $10 billion to the stack. Together, the two projects would give Musk control over both computing and the electricity that feeds it. Delays on either side would land on the same income statement in the same years, and both schedules carry the risks Musk's plan has always faced: cost overruns and any weakening of state incentives. Talk of a possible Tesla-SpaceX merger could tie the programs even closer, though nothing has been agreed. Tesla's Bitcoin holdings, which the company has left unchanged in recent quarters, sit on the same balance sheet now funding both programs. The stock has rebounded in recent sessions but remains down for the year.

TSLA at $383.79

For shareholders, the arithmetic is simple: Crystal Sun and Terafab commit billions now and pay back only after 2028, so execution, not the groundbreaking, is what the stock will be judged on. COINOTAG data shows Tesla trading at $383.79, up 1.28% over the past 24 hours, inside a $369.93 to $385.27 range. Our composite scoring marks $376.20 as the strongest support, at 100/100, and $399.28 as the strongest resistance, at 91/100. The daily RSI reads 52.7, the MACD signal is bearish, the trend label is sideways, and perpetual open interest stands near $60.4 million. A daily close above $399.28, or a loss of $376.20, would give the market its next clear direction.
