Yingli Green Energy Holding Company Ltd. has commercialized 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 bifacial series monocrystalline modules will be installed on a 50-MW power plant in Datong, Shanxi province, which was rewarded to Yingli under China’s “Top Runner” program.
The TwinMAX module is a frameless module that is comprised 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 state of the art PANDA n-type monocrystalline solar cells with cell efficiency that could reach as high as 20.5 percent and average module efficiency that could be over 17 percent. The TwinMAX bifacial series modules can generate from both the front and rear sides of the cells, allowing power yields up to 30 percent more than traditional monocrystalline modules.
TwinMAX modules possess strong durability and resistance to PID (Potential Induced Degradation) and are able to perform well under various harsh environments such as exposure to high temperature and humidity, salt mist and sand. With a maximum system voltage of 1500 Volts (V), TwinMAX modules can improve system performance and help to reduce balance-of-system costs. In addition, TwinMAX modules carry a 30-year linear warranty, which theoretically could provide more than 20% power gain for customers compared to industry standard 25-years linear warranty.
“We are excited to introduce and offer one of the most advanced products in the industry to our customers with the commercialization of our TwinMAX module,” commented Dr. Dengyuan Song, Chief Technology Officer of Yingli. “This is also consistent with our long-term commitment of reducing the cost of solar power generation and making solar electricity affordable and accessible for all through continued technology innovation.”
Have you checked out our YouTube page?
We have a ton video interviews and additional content on our YouTube page. Recently we debuted Power Forward! -- a collaboration with BayWa r.e. to discuss higher level industry topics as well as best practices / trends for running a solar business today.
Our longer running side project is The Pitch -- in which we have awkward discussions with solar manufacturers and suppliers about their new technology and ideas so that you don't have to. We discuss everything from residential rail-less deck attaching and home solar financing to large-scale energy storage value stacking and utility-driven new home solar + storage microgrids.
