The business operations of the insolvent Wavelabs Solar Metrology Systems GmbH have been successfully transferred to the Dutch Eternal Sun Group as part of an internal administration procedure. The company develops LED-based flash and continuous light solar simulators for electrical performance testing (IV characterisation) of solar cells and modules.
A team led by GÖRG partners Christopher Schiller and Dr Michael Schaumann, together with Falkensteg Corporate Finance GmbH, provided comprehensive advice to Wavelabs Solar Metrology Systems GmbH (‘WAVELABS’) on the transaction.
With this acquisition, Eternal Sun, a leading provider of test technology for solar modules, is acquiring significant assets, technologies and know-how from WAVELABS. The aim is to complement and further develop the technology portfolio internationally.
The parties have agreed not to disclose the financial details of the transaction. The transaction has already been completed.
WAVELABS was founded in 2011 and quickly developed into an established supplier of solar simulators. The company's products are used by research institutes, test laboratories, universities and major PV manufacturers around the world. In spring 2025, due to declining investor interest and a general decline in demand in the industry, WAVELABS initiated insolvency proceedings under its own management in order to restructure and realign itself. Rüdiger Bauch of Schultze & Braun was appointed as administrator. The self-administering management was supported by Reinhard Klose of Flöther & Wissing.
