About ASWS
ASWS GmbH, based in Mettmann near Düsseldorf, is a German manufacturer of photovoltaic modules. The company offers several product series – Silver Style, Boost S and Strong Style (also available as Black Mesh or with HJT solar cells) – with outputs from 410 to 475 watts. The modules rely on bifacial solar cells in a glass-glass laminate, half-cell technology for good yields under shading, and an innovative bonding technique between the aluminium frame and the laminate. Maximum production capacity is 800 megawatts per year. The management team can look back on more than ten years of experience in the solar industry, which flows into the development and design of the modules. The sales channel is specialised partners such as solar installers, retailers and wholesalers; private customers are referred to specialised partners. Quality is ensured through in-house, end-to-end inspections, backed by at least 15 years of product warranty and 30 years of performance warranty.
