Yingli Commercializes TwinMAX Dual-Glass Solar Modules

Yingli Green Energy Holding Co. Ltd. says it has successfully commercialized its TwinMAX 60-cell, dual-glass module (including the standard series and the bifacial series) and TwinMAX 72-cell, dual-glass module (standard series). The bifacial series monocrystalline modules will be installed on a 50 MW power plant in Datong, Shanxi province, China.

Yingli says the TwinMAX module is a frameless module that consisting of two layers of 2.5 mm-thick tempered glass, which replaced the conventional back sheet and glass structure. Specifically, TwinMAX bifacial series modules integrate technology from Yingli’s PANDA n-type monocrystalline solar cells with cell efficiency that could reach as high as 20.5% and average module efficiency that could be over 17%, according to the company. The TwinMAX bifacial series modules can generate from both the front and rear sides of the cells, allowing higher power yields.

The company adds that the TwinMAX modules have a maximum system voltage of 1,500 V and possess strong durability and resistance to potential induced degradation, making them suitable for harsh environments.
