Global leader in dual-glass technologies

Trina Solar is the first PV manufacturer to acquire the dual TÜV/UL certification and achieve mass production. Trina Solar has acquired 18 authorized patents related to dual-glass technology. The cumulative global shipments of Duomax modules ascend to nearly 3GW, putting Trina Solar at the forefront of the solar industry.

Higher reliability and better durability

Duomax M 144-cell modules adopt a heat strengthened dual-glass structure with strong anti-cracking capability. From intensive on-site testing, we found that more than 98% of the double-glass modules could achieve zero cracking. Duomax is ideal for harsh climatic conditions: its dual-glass design reduces UV ageing, degradation and corrosion. Moreover, half-cut technology with heat spot resistance feature will lower the risk of damage.

Higher power through technical innovation and integration

This Duomax M module integrates various technologies like dual-glass structure, half-cut cells and multi busbars (MBB) design, achieving 25W higher peak performance than regular mono PERC dual-glass modules. Half-cut cell design allows the power loss caused by ribbon resistance to be reduced to 1/4 compared to full cells, which improves the overall module efficiency by more than 2%. And multi-busbar technology application can shorten the current conduction distance by over 50% and thus lower the internal ribbon resistance loss. With finer and narrower busbars, more sunlight will be reflected back to the round ribbon, thus increasing energy efficiency.

Higher performance

Half-cut cell technology allows the module to work at lower operating temperatures, which improves energy generation per watt. The unique cell string structure can significantly reduce the energy loss due to the mismatch caused by inter-row shading. Compared to standard modules, Duomax M offers a faster return on your initial investment with its 0.5% annual power degradation and an estimated 25 percent greater lifetime energy production.
