Tesla has unveiled ambitious plans for “Project Crystal Sun,” a massive US$10.1 billion vertically integrated solar manufacturing campus in Fort Bend County, Texas. Filed with the Texas Comptroller, the proposal details a 3,050-acre facility near Richmond designed to handle the entire solar value chain, from silicon processing to finished solar modules. The project represents Tesla’s largest manufacturing investment to date, aiming to create nearly 10,000 permanent jobs. With construction slated for 2026 through 2028, the site is expected to begin commercial production in early 2029, marking a significant shift toward domestic, large-scale solar component manufacturing.
The financial breakdown of the project includes US$1.5 billion allocated for real property and US$8.6 billion dedicated to advanced manufacturing equipment. While the application does not specify an annual production capacity, industry analysts suggest the scale of investment could support output exceeding 10GW. The facility is designed for high-volume automation, incorporating specialized systems for ingot production, wafer slicing, chemical coating, metallisation, and rigorous cell testing. Beyond core production, the campus will feature comprehensive utility infrastructure, chemical storage, and safety systems to support a fully integrated operation.
Tesla is pursuing a 10-year property tax limitation under the Texas Jobs, Energy, Technology and Innovation Act to facilitate the development. The project is projected to generate 1,147 construction jobs in addition to its permanent workforce. This move toward vertical integration is seen as a strategic response to a tightening trade environment, characterized by new Section 232 regulations and ongoing antidumping and countervailing duty cases targeting solar imports from various nations. As US manufacturers navigate these complex import barriers, Tesla’s investment signals a growing industry trend toward securing upstream supply chains within the United States.
