On June 16, trucks loaded with Trina Solar's 210mm 670W Vertex ultra-high power modules left from the company's manufacturing center in Yancheng, in eastern China'sJiangsu province, and drove to the solar park in Dachaidan, Qinghai, in western China. It was the first of many such shipments, with all modules for the project on track to be delivered by the end of August, adding up to a total power output of 112MW. The modules are scheduled for use in the 100 MW Phase I of the Dachaidan PV Project, a massive facility that, when finished, will have a capacity of 1,000 MW. The project exclusively uses Trina Solar 670W series ultra-high power modules. Trina Solar's 210mm 670W Vertex series module, which inherits 210mm Series' sophisticated non-destructive cutting and high-density packaging technologies, is a high-power, high-efficiency, reliable and high generating capacity product, suitable for large-scale ground power plants. From the upstream perspective, the module series boasts a reduction in the non-silicon cost of silicon wafers and cells, while, from the downstream perspective, the cost of racks, pile foundations, cables and labor of the mounting system has also been lowered. Compared with competitors' best 585W modules, the string power of the 670W module is 41% higher, while a saving of 2-3% is achieved in LCOE. When compared with mainstream 450W modules, the 670W version reduces the system BOS cost by 0.15-0.2 yuan/watt, and LCOE by 4-6%.
