Struggling China-based PV manufacturer Yingli Green Energy has launched its new high-performance and durable ‘TwinMAX’ series of modules, which includes its ‘PANDA’ n-PERT bifacial cells. 

Yingli Green said that the TwinMAX series had been commercialised and included its TwinMAX 60 Cell high-efficiency dual glass module (including the standard series and the bifacial series) and TwinMAX 72 Cell high-efficiency dual glass module (standard series). 

The TwinMAX series is a frameless module that is comprised of two layers of 2.5mm thick tempered glass, which replaced the conventional back sheet and glass structure. 

The ‘PANDA’ n-PERT bifacial series modules includes solar cells with cell efficiencies that could reach as high as 20.5% and average module efficiency that could be over 17%, and the potential to allow power yields up to 30% more than traditional monocrystalline modules, according to the company.  

The bifacial series monocrystalline modules would also be installed on a 50MW power plant in Datong, Shanxi province, which was rewarded to Yingli Green under China's ‘Top Runner’ program.

The company also noted that the TwinMAX modules offer improved resistance to PID (Potential Induced Degradation) and are able to perform well under various harsh environments and are being offered with a 30-year linear warranty, which theoretically could provide more than 20% power gain for customers compared to industry standard 25-years linear warranty, according to the company.

TwinMAX modules will also be made available with a maximum system voltage of 1500 Volts (V) that reduce balance-of-system costs.
