Seraphim Unveils the S4 Half-Cell Series PV Module

Jiangsu Seraphim Solar System Co. Ltd., a China-based solar products manufacturer, has launched its new generation of products – the S4 half-cell (PV) series photovoltaic modules.

According to Seraphim, the new modules can achieve a maximum output of up to 540 W – with a maximum module efficiency of 21.1% – by integrating 182 mm silicon wafers with technologies such as PERC (Passivated Emitter Rear Cell) and multi-busbars (MBB ), half-cut cell and high density packaging.

The products have two iterations – a monofacial and a bifacial module. Both modules will go into series production in the first quarter of 2021 – with an expected annual capacity of 3 GW after an equipment upgrade.

The new bifacial S4 half-cell module can increase the power output from 10% to 30% under different soil conditions and thus significantly reduce the costs for electricity (LCOE) and system balance (BoS). In addition, the application of double glass technology makes the S4 bifacial half-cell module less prone to micro-cracks. The S4 module is equipped with a frame that can withstand greater loads – even without a bar on the back, the front of the module alone can withstand a static mechanical load of around 5,400 Pascal.

Since its establishment in 2011, Seraphim has specialized in the research, development, production, innovation and sales of PV products. To date, more than 8 GW of Seraphim products have been installed in over 40 countries worldwide.
