Series Sera (High efficiency monofacial modules 655–670 W) 4 variants
Seraphim Sera (High efficiency monofacial modules 655-670 W) is a series designed for installations where maximum power generation from a limited area and faster installation by the installer are key priorities. The modules utilize large-format silicon cells and a half-cut architecture, which helps minimize losses due to resistance and improves performance under partial shading. The use of multi-busbar (12BB) technology increases the efficiency of current collection from the cells and supports more stable operation under varying solar conditions. The high cell density is also noteworthy – smaller spacing and refined lamination result in better utilization of the module's active area.
This solution is ideal for PV farms, large industrial rooftops, and commercial projects where lower BOS (Balance of System) costs, simpler logistics (fewer modules for the same power), and reliability, confirmed by environmental and PID degradation tests, are crucial.
