Meyer Burger reacts to material shortages and introduces short-time work at the solar cell plant in Thalheim

Meyer Burger Technology AG will introduce short-time work at its Thalheim site (city of Bitterfeld-Wolfen, Germany) from May 1, 2025. This was agreed yesterday by management and the works council. Approximately 300 employees who previously produced high-performance solar cells in 24/7 operation will be affected. The measure is intended to save costs in the short term. The reason for the short-time work are temporary material bottlenecks in production.

Material bottlenecks have also led to an adjustment of production processes at the U.S. facility in Goodyear (Arizona), which processes the solar cells from Thalheim into solar modules. Technical work at the plant now alternates daily with the production of solar modules as part of the ongoing ramp-up. In addition, further adjustments to the workforce are being prepared in order to reduce costs.
