Domestic solar and battery manufacturing with vertically integrated U.S. supply chain
T1 Energy operates a 5 GW solar module plant in Texas and is scaling toward cell manufacturing—a capital-intensive, process-heavy operation reflected in their tech stack (Siemens, Mitsubishi, EtherCAT, TwinCAT for factory automation) and their hiring mix. Active projects span wet-process line design, robotics integration, and process control automation, while pain points cluster around equipment uptime, compliance, and production scaling—all indicators of a manufacturing firm in mid-scale growth mode managing both supply-chain expansion and operational complexity.
