SMALL CHANGES, BIG ACCOMPLISHMENTS 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.

REACHING THE COMPATIBILITY BOUNDARY OF MAINSTREAM SOLAR SYSTEM

Compatible with the existing packaging scheme, container space and logistics methods.

The size and width of the modules are within the arm span, thus ensuring the installation efficiency and reducing the risk of damage.

Maintains maximum compatibility with existing solar system design while ensuring the system safety and reliability.

Have all the advantages of more power per unit area and reduced BOS cost, and also can be effectively combined with mainstream 1p and 2p mounting systems.

IMPROVED RELIABILITY

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.
