Small Changes, Big Accomplishments

S4 Bifacial Series

SEG focuses on value creation and in the winter of 2020 launches a new generation of high efficiency PV modules, the S4 bifacial series. The new series integrates 182mm large-size silicon wafers with PERC, multi-busbar, half-cell, bifacial
technologies and high-density encapsulation. Technology
integration enables the S4 bifacial series to increase the
efficiency of the module up to 21.1%, and the maximum power output on the front side to 540W.
