Tesla Plans $10.1B 'Project Crystal Sun' Solar Plant in Texas

AUSTIN, Texas — Tesla is planning one of the largest additions to its Texas manufacturing footprint yet: a $10.1 billion, vertically integrated solar cell factory in Fort Bend County, about 40 minutes outside Houston. A public application filed under the state's Jobs, Energy, Technology & Innovation (JETI) Act, internally code-named "Project Crystal Sun," lays out a plant that would make photovoltaic cells and assembled modules from the raw wafer all the way to the finished panel.

An End-to-End Solar Fab

According to the filing, construction is scheduled to begin later this year and wrap in 2028, with commercial operations targeted for the first quarter of 2029. What sets Project Crystal Sun apart is its scope: rather than importing cells or wafers from overseas suppliers, Tesla intends to produce the full stack in-house.

Equipment detailed in the application includes wafer and ingot manufacturing machinery, coating equipment, metallization and printing lines, cell testing and quality-control hardware, automated material handling systems, cleanrooms and supporting utility infrastructure. It is the kind of soup-to-nuts operation Elon Musk has hinted at for years, echoing his earlier idea of a solar Gigafactory in North America to keep the company power-fed through the AI boom.

A Massive Economic Footprint

The projected impact on Fort Bend County is enormous. The site expects to create 9,712 permanent full-time jobs alongside 1,147 peak construction jobs. Total direct and indirect economic activity is estimated to generate roughly $6.4 billion in state and local taxes while boosting Texas GDP by about $107 billion over its lifetime.

That scale would make Project Crystal Sun a cornerstone of Tesla's energy division, which has become one of the company's fastest-growing and highest-margin segments. Domestic photovoltaic production would feed Tesla's own energy products, from residential solar to utility-scale installations, and pair naturally with the battery storage buildout already underway in the state, including the recently activated 500 MWh Megapack project on the Texas grid.

Powering The AI Era

The strategic logic runs deeper than selling more panels. Tesla increasingly views energy generation as the constraint on its AI ambitions, with massive training clusters demanding immense, reliable power. By building solar cell manufacturing alongside battery storage in Texas, the company is vertically integrating the electricity supply needed to keep its AI clusters, factories and consumer products running for years to come.

The move also arrives as Musk's broader Texas empire expands, from the joint Tesla-SpaceX Terafab chip venture to SpaceX's own solar fab supporting orbital data centers. As reported by Not a Tesla App, the Project Crystal Sun filing is still an evaluation rather than a final commitment, and specifics could shift before ground is broken. But the sheer size of the proposal signals where Tesla sees its next frontier: making the clean energy that will power everything else it builds.
