1996
- Würth Solergy: Start of the first photovoltaic activities under the umbrella of the Würth Elektronik Group
- Sale of grid-connected photovoltaic systems in Germany and stand-alone systems, in India for example
1999
- Würth Solar GmbH & Co. KG was founded with the goal of developing Europe's first commercial manufacturing plant for CIS solar modules
- Basis: Basic CIS research by the Institute of Physical Electronics (ipe), Stuttgart and development of the production technology on a laboratory scale by Zentrum für Sonnenenergie- und Wasserstoffforschung Baden-Württemberg, Germany (ZSW)
2000
- Installation of the pilot line in the former EnBW coal-fired power station in Marbach/Neckar
- The first production line for CIS solar modules is put into operation
2001
- Continuous optimisation of the manufacturing technology
- Implementation of the first large applications - solar tower in Heilbronn and primary school in Ludwigsburg
2002
- Important goals, such as process stability, efficiency and yield exceed expectations. Around 2,800 CIS modules leave the production line
- Implementation of prestigious projects, such as the head office of Würth Elektronik eiSos Waldenburg and Würth Holding Chur/Switzerland, where the advantages of CIS technology become very evident
2003
- Increase in nominal capacity to around 1.2 MW p/a through investment in a second CIS plant
- Start of the second production line for CIS solar modules
2005
- Cornerstone laid for CISfab, the world's first factory for large-scale production of CIS solar modules
2006
- Opening of CISfab in Schwäbisch Hall, Germany
- Start of the world's first large-scale production of CIS solar modules, called GeneCIS
- Foundation of Würth Elektronik Research
2007
- Full utilisation of CISfab with a capacity of 15 MW; daily production of 550 modules
2008
- July: Expansion to 30 MW production capacity completed; that corresponds to an annual output of 350,000 GeneCIS solar modules
2010
