Trina Solar has formally unveiled its latest Duomax V bifacial double-glass modules and Tallmax V back sheet. Based on the 210mm large-size silicon wafer and monocrystalline PERC cell, the new modules come replete with several innovative design features allowing high power output of more than 500Wp and module efficiency up to 21%, consolidating the Company's leadership and embracing a new era of PV 5.0.
According to preliminary estimates from large-scale ground mounted power stations in China's Heilongjiang province, compared with conventional 410W bifacial double-glass modules, the 500W Duomax V can reduce the balance-of-system (BOS) cost by 6 to 8 per cent and the levelized cost of energy (LCOE) by 3 to 4 per cent. Trina Solar will formally start accepting orders in the second quarter of 2020 and is set to achieve mass production in the third quarter, with production capacity expected to exceed 5GW by the end of the year.
Based on its superior multi-busbar technology, Trina Solar's research and development team has introduced an innovative design that integrates advanced three-piece, non-destructive cutting and high-density packaging technologies. This further reduces the resistance loss and significantly improves the anti-cracking, anti-hot spot performance of the modules while maximizing space utilization. By doing so, the scientists created high-power modules characterized by high efficiency and high reliability. If the traditional half-cut cell design were applied to 210mm ultra-large silicon wafers, the high current output characteristics of the modules could trigger system challenges, or cause the module to crack or run afoul of DC terminal limits.
In addition, the unique design
