After eight years at the helm of the SONNENSTROMFABRIK / CS Wismar GmbH (SONNENSTROMFABRIK), Dr. Bernhard Weilharter will leave the company on June 30, 2023, to take on a new challenge outside the CENTROTEC Group.

SONNENSTROMFABRIK (CS Wismar GmbH), one of Europe's most leading and modern manufacturers of high-quality photovoltaic modules, successfully received the fire protection certificate in accordance with the UNI 9177 standard for its Glass/Glass and Glass/Foil Photovoltaic modules of the "EXCELLENT" series at the beginning of the year.

SONNENSTROMFABRIK (CS Wismar GmbH), one of Europe’s cutting-edge leaders in manufacturing high-quality photovoltaic modules, offers three new sizes for both glass/glass and glass/foil PV-panels from late autumn. Using a modern half-cut cell technology and a wafer size of 182mm² SONNENSTROMFABRIK’s PV-modules will achieve high performance values up to 490Wp.

SONNENSTROMFABRIK (CS Wismar GmbH), one of Europe’s cutting-edge leaders in manufacturing high-quality photovoltaic modules, has advanced the design of its high-grade black and full black glass/glass modules. The integration of a black monolayer within the double-glass laminate makes the design even more stylish. The new design by SONNENSTROMFABRIK doesn’t just look good, it also makes the elegant PV modules even more durable.

SONNENSTROMFABRIK (CS Wismar GmbH), one of Europe’s cutting-edge leaders in manufacturing high-quality photovoltaic modules, has invested in new, state-of-the art machinery for the manufacture of solar cells up to 220 mm in size with half-cut and tri-cut cell technology. This prepares the company for the trend toward even larger wafer sizes, which will become the new global standard in the next few years.

SONNENSTROMFABRIK (CS Wismar GmbH), one of Europe’s cutting-edge leaders in manufacturing high-quality photovoltaic modules, has successfully made the final assembly stage of its high-quality PV modules fully automated and strengthened its quality assurance and quality control at the same time. The fully automated production line is equipped to manufacture PV modules with a total annual capacity of up to 200 MWp. SONNENSTROMFABRIK’s existing, partially automated, final assembly facility will remain in operation to ensure sufficient flexibility in manufacturing OEM products and special modules.

SONNENSTROMFABRIK (CS Wismar GmbH), one of Europe’s cutting-edge leaders in manufacturing high-quality photovoltaic modules, celebrated continued sustainable and profitable growth last year despite the negative economic impact of the Covid-19 pandemic. The company managed to increase the sales of its high-quality PV modules by 30 percent. As in previous years, the company closed out the 2020 financial year with a positive financial result, setting it apart from many of its competitors.

SONNENSTROMFABRIK (CS Wismar GmbH), one of Europe’s cutting-edge leaders in manufacturing high-quality photovoltaic modules, has developed a full-surface photovoltaic installation for the hip roof covering 58 dwellings in Amsterdam’s new Houthaven quarter. Its innovative combination of a roof-mounted structure with aesthetic roof-integrated optics was designed and constructed by the technical engineering team at SONNENSTROMFABRIK in close collaboration with the client Oranjedak – a major player in the Dutch roofing industry.

SONNENSTROMFABRIK (CS Wismar GmbH), Europe’s cutting-edge leader in manufacturing high-quality photovoltaic modules, is becoming part of the group CENTROTEC Sustainable SE, based in Brilon, Germany.

Located at the heart of Amsterdam, the oldest horse-riding school in the Netherlands will be covered by transparent PV modules from Sonnenstromfabrik’s Brilliant module series.

Sales increased by 50 percent compared to the same period of previous year. Business in Germany, the Netherlands, France and Switzerland is growing particularly positively.

Sonnenstromfabrik and Provence Eco Energie installed a high-transparent photovoltaic sun protection structure for the Collège de la Nativité in Aix-en-Provence.

At the Svenska Solelmässan 2019 Dr. Bernhard Weilharter, Managing Director of Sonnenstromfabrik, pleaded at the end of October in Uppsala in front of an international trade audience for the reduction of CO₂ emissions in the energy mix.

Our new high-power PV modules offer a good five percent better yield. The power output offered by the 60-cell PV modules has risen from 305 Wp to 320 Wp, or in some cases from 310 Wp to 325 Wp, thanks to a new design in combination with the familiar format.

In May, Sonnenstromfabrik presented its newly developed AC modules at Intersolar in Munich. The core of the AC module technology is an integrated micro inverter from Enphase.

We have extended our glass/glass in-roof module series by glass/foil modules with 60, 54 and 48 cells. With the three new PV module formats in glass/foil design, lower-priced photovoltaic modules are now available as entry-level models for integrated solar roof concepts.

Sonnenstromfabrik is a preferred supplier of the Dutch House Energy Optimum (HEO) system. HEO (www.bouwheo.nl) is a strategic alliance of A-brand suppliers of high-quality products and systems for insulation, shading, ventilation, heating, cooling and solar energy.
