Germany: Sonnenstromfabrik resumes PV module production


The third time may turn out to be a charm for Sonnenstromfabrik, the PV manufacturing facility in Wismar, Germany, that has again begun production following ownership by two different, now defunct companies, including original owner Centrosolar.

Now owned by CS Wismar GmbH and managed by a team composed of former Centrosolar personnel, including CEO Alexander Kirsch, Sonnenstromfabrik has restarted operations and is now producing solar modules under its proprietary Sonnenstromfabrik brand as well as for the company’s growing number of OEM clients.

“The demand is there,” said CS Wismar sales director Bernhard Weilharter. “The market will recall good experiences with modules from Wismar – over our 20-year production history at Wismar we had a complaint rate of less than 0.02 % p.a. – such quality rates are unequaled in the industry.”

The fab boasts a production capacity of 525 MW — among the largest in Europe. The company’s product range comprises long-life modules of glass-glass design, standard modules, off-grid modules and panels for roof integration.

Sonnenstromfabrik was originally built by Centrosolar, which filed for insolvency in 2014. It was then acquired by Solar-Fabrik, which then went belly-up in 2015.

As part of the Centrosolar it served as the production base for the group’s own solar modules as well as for products made for TSMC, Bosch, DuPont and Conergy.

The new team is eager to get back into the game. “We start out clear of debt and with huge commitment,” said Kirsch. “But above all, we know how to make good solar modules.”
