Trina Solar Co. Ltd. has presented a new generation of its Vertex module with a single panel power of 670 W.
According to Dr. Zhang Yingbin, head of product strategy and marketing at Trina Solar, the 670 W Vertex features non-destructive cutting, high-density connections, multi-busbars (MBB) and other technologies – with low voltage and high voltage string power and other core functions. The MBB and the high-density connection improve the module efficiency up to 21.6%, while the non-destructive cutting developed by Trina Solar significantly reduces the risk of micro-cracks in cells and loss of performance.
“Trina Solar was driven by innovative, reliable quality and customer benefit,” says Yingbin. “The ultra-high performance Vertex 670 W reduces BOS costs and LCOE. This will help meet the renewable energy targets and accelerate the pace of the PV industry to navigate the grid parity era. “
Increasing the performance of each string is a key factor in reducing BOS costs. When introducing the new module, Yingbin stated that in large power plants (-20 ℃) the 670 W Vertex has 28 modules on each string. Compared to other 500 W + high-performance modules in the industry, the 670 W Vertex module achieves an overall increase in output of up to 18,760 W per string, 34% more than the 500 W + modules. The 670W modules can reduce the non-silicon costs of silicon wafers and cells for the upstream supply chain – and the costs for trackers, pile foundations, cables and labor for those downstream.
For unpacking and installation, Trina Solar provides simple and easy-to-use auxiliary tools with standard configuration that can be used to support the box body to ensure safety throughout the process. Many empirical studies have shown that 670 W modules also support traditional installation methods. In addition, the number of modules can be reduced by approx. 24%, which leads to a reduction in overall installation costs of 5-7%.
By the end of 2021, 210 modules are expected to make up 120 GW in the solar industry. According to Trina Solar, 210 modules will account for 70% to 80% of total deliveries this year.
