Seraphim unveils new S4 half-cell series PV modules with mass production starting in Q1 2021

Chinese solar product manufacturer Jiangsu Seraphim Solar System Co., Ltd. (Seraphim) released its new S4 half-cell series photovoltaic (PV) modules. According to the company, the modules can achieve a maximum power output of up to 540 W, with the maximum module efficiency reaching 21.1 percent, by integrating 182 mm large silicon wafers with the state-of-arts technologies such as passivated emitter rear cell (PERC), multi-busbar (MBB), half-cut cell, and high-density packaging.
The products have two categories, namely, monofacial module and bifacial module; both will be put into mass production in the first quarter of 2021, with an expected annual capacity of 3 GW after an equipment upgrade.
The module is for use in large ground mounted power stations. S4 bifacial is equipped with a frame to withstand a larger load. Even without beams on the back, the front of the module alone can withstand a static mechanical load of about 5,400 pascal (Pa).
