Broad product portfolio thanks to intelligent production footprint
Sonnenstromfabrik produces both its own products under its own brand name but also third-party modules, which it makes on behalf of other solar manufacturers. Our product range comprises framed and frameless glass/glass modules, framed standard modules of glass-foil design and special modules such as off-grid modules and roof-integrated modules.
Our production equipment is cutting edge.
Sonnenstromfabrik employs fully automated and high performance production facilities. For the glass/glass and special modules, Sonnenstromfabrik’s team of developers created special machining solutions to assure consistently high quality and process reliability. The entire production process is comprehensively monitored. The raw materials, components and modules are put through extensive tests.
Carbon balance certified by Certisolis
Sustainability in the production of modules is a central aspiration of Sonnenstromfabrik. As one of the first companies we have optimized our carbon footprint. Our extraordinary low carbon footprint is also certified by Certisolis. Products of Sonnenstromfabrik convince by a carbon footprint significantly below values of its competitors.
Sonnenstromfabrik operates an inhouse laboratory
Production plant in Wismar
The plant’s origins go back around 25 years. Centrosolar Group AG took over the plant in 2006. New buildings went up at the present location in 2008 and 2011. The plant has since been modernized several times. In 2016, CS Wismar GmbH took over the operations with a team1 from the former Centrosolar. Centrosolar itself has focused its activities entirely on North America and still sources Centrosolar modules for the US market from Sonnenstromfabrik.
