Trina Solar says its recently launched 670W Vertex Module has an efficiency of 21.6 percent

12% falls in transportation cost and 5-7% falls in installation cost.


China — Trina Solar Trina Solar unveiled a new generation of ultra-high power Vertex module with a single panel power of 670W. The company says the series obtained the IEC certification from TÜV Rheinland after passing a complete reliability test.



According to Dr. Zhang Yingbin, Trina Solar’s head of product strategy and marketing department, the 670W Vertex series inherits the high-density interconnection and other high-precision technologies of the 210mm modules; with the ultra-high module power, the single string power gets 34% higher than that of other 500W+ modules in the industry.

He adds that the 670W Vertex modules maximize the container space utilization in transportation, as a result of which the 12% up in the loading power and 5 – 7% down in the installation cost, creating more room for reduction of the LCOE and BOS cost.

The 670W Vertex modules inherit the four 210 key technologies

As a type of 210mm module, Trina Solar’s 670W Vertex bears non-destructive cutting, high-density interconnection, multi-busbar (MBB) and other forward-looking innovative technologies, with low voltage, high string power and other core features, presenting efficient and reliable product performance. The MBB and high-density interconnection improve the module efficiency to up to 21.6%, while the non-destructive cutting pioneered by Trina Solar significantly reduces the risks of cell micro crack and power loss.

34% higher power generation

Increasing in power of the single string is the core factor to reduce the BOS cost. At the launch of the 670W Vertex, Dr. Zhang Yingbin explained that in large-scale power plants (-20℃), the 670W Vertex has 28 modules on each string. Compared to other 500W+ high-power modules in the industry, the 670W Vertex module achieves a total power increase of up to 18,760W per string, 34% higher than that of the 500W+ modules.

670W Vertex module is suitable for large-scale power plants, especially the low-cost power plants which are very sensitive to investment costs, because the 670W modules can reduce the non-silicon cost of silicon wafers and cells for the upstream supply chain, and reduce the cost of trackers, pile foundations, cables and labor for the downstream.

Compared to other 500W+ modules in the industry, BOS cost savings are at least 0.08-0.09 yuan per watt, hence with a significant overall advantage.

At the launch conference, Trina Solar showcased how the panels performed in transportation and installation.

At the beginning of this year, Huawei, Si-Neng, and Sungrow launched inverters compatible with the 600W+modules, and TBEA, GOODWE, Ginlong, Kstar, SMA and some other inverter manufacturers also announced their products compatible with high-power 210mm modules. Trina SOlar says these 18.4A – 18.5A inverters will also be fully compatible with 670W modules.

Tracker manufacturers – Arctech Solar, Array Technologies, GameChange Solar, IDEEMATEC, Nextracker, PVH, Soltec, TrinaTracker – announced trackers of full compatibility with 210mm ultra-high power modules.
