S4 Bifacial Module

Seraphim 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 a maximum power output on the front side of 540W.Compared with larger module products, the S4 bifacial series have a number of outstanding characteristics, such as a lower working current and power loss, a lower temperature coefficient, high low irradiance performance, high power output and low hot spot effects.
Moreover, it provides for two installation methods according to field conditions: by rails and clamps. In both cases, the S4 bifacial series modules are qualified for 5400Pa static load on the frontside even when there is no cross-beam support on the back.
