U.S. solar module and battery manufacturing with 5 GW annual capacity
T1 Energy operates a vertically integrated solar and battery manufacturing supply chain centered on a 5 GW module plant in Texas, with plans for a downstream cell facility. The tech stack reflects a capital-intensive, process-driven operation: SAP/Oracle ERP systems anchoring resource planning, Siemens PLCs and industrial control protocols (Modbus, OPC UA, Ethernet/IP) managing production lines, and MES/CMMS layers for real-time equipment and maintenance visibility. Hiring is heavily skewed toward manufacturing (31 roles) and engineering (21), with accelerating velocity and mid-level concentration — a pattern consistent with ramp-up operations and process stabilization in high-volume environments.
