Trina Solar Co., Ltd., a global PV and smart energy total solution provider, has officially announced the availability of the 670W Vertex module in the Middle East and Africa
According to Zhang Yingbin, Trina Solar's head of product strategy and marketing department, the 670W Vertex series inherits the non-destructive cutting, 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. In addition, 670W Vertex modules maximise the container space utilisation 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.
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
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.
Packaging & transportation
For 600W+ series products, Trina Solar innovated the packaging method to vertical placement, so that the width of the modules is no longer limited by the height of the container. Such packaging makes the best use of the container's internal capacity. Compared with the traditional ways, the loading power increases by 12%, which introduces a 12% cost reduction in transportation.
Installation
For the stage of unpacking and installation, Trina Solar provides simple and easy-to-use auxiliary tools with standard configuration, which can be used as the support of the box body to ensure the safety in the entire unpacking process.
Mechanical loading performance
The load capacity of Trina Solar's 670W modules is also tested. On one hand, the optimised frame design and material selection prevents the deformation even when the module area increases, and reduces the risk of micro crack. On the other hand, the non-destructive cutting ensures that each cutting surface of the cell is smooth and crack-free.
The 210mm modules, integrating high efficiency, high reliability, high power generation and low cost have been increasingly favored by the market, with tenders for large-size modules accounting for more than 78%. By the end of 2021, 210 modules production capacity is expected to achieve 120 GW in the entire industry. At Trina Solar, 210 modules will account for 70% to 80% of its overall shipments this year.
