WINAICO launches Back Contact Solar Module with 480 watts

WINAICO, a premium solar PV module manufacturer, is announcing the upcoming arrival of its new WST-480BDX54-B2 Ultra Black Glass-Glass module to the European market. Back Contact solar modules differ from conventional solar modules in that all electrical contacts are located on the rear side of the solar cells.
Designed for residential applications with cutting-edge back-contact cell technology, this next-generation panel offers peak efficiency, durability, and aesthetics for installers and homeowners alike.
With module efficiencies up to 23.5%, a temperature coefficient of just -0.26%/°C, and up to 20% bifacial gain, the WST-480BDX54-B2 represents a significant leap in performance.
The use of glass-glass architecture ensures long-term durability with improved resistance to microcracks and environmental stress—backed by WINAICO’s 30-year product and performance warranty.
The product also includes one year of free system insurance, which covers not only the PV modules but extends to critical system components like batteries and inverters. This unique 3-in-1 insurance offering provides unmatched peace of mind for system owners.
“With the introduction of our new 480-watt back-contact module, we are setting new standards in aesthetics, performance and reliability. Thanks to maximum power density and completely concealed contacts, we offer our customers not only maximum energy yield, but also a particularly attractive design,” said Marc Ortmanns, Director Operations of WINAICO Deutschland GmbH.
