About product

Trina Solar 390W Duomax Twin is a 144-cell bifacial module for residential and commercial systems. The backside gain reaches up to 25%, depending on the albedo. Half-cut cell design ensures better shading tolerance and improves reliability of a panel.

Features:

  • 390W frontside power output
  • 144 cell bifacial monocrystalline module
  • Bifacial gain up to 25%
  • up to 23.8% efficiency with the active backside
  • MC4 EVO2/TS4 Connectors
  • 1500V Maximum system Voltage

Active backside provides high efficiency

The frontside of Duomax Twin puts out 390 Watts of power with 19% energy conversion rate. However, you can get up to 25% more energy from the backside. When it’s working at full capacity, the output of a module reaches up to 488 Watts with 23.8% efficiency.

Half-cut cell technology reduces power losses

Trina Solar engineers use half-cut cell design to reduce the power losses and increase the reliability of a module. Cells become more durable and the risk of hot spots development is lower. What is more, it increases the shading tolerance of a panel.

Ready for harsh weather conditions

Trina Solar panel is resistant to acid and alkaline. It is made to survive harsh weather conditions: wind, rain, hail, tornadoes and hurricanes. The module can withstand 2400 Pa load which is equivalent to 140 mph wind.

Comes with strong warranties

Duomax Twin comes with a 10-year product and workmanship warranty. What is more, there is a 30-year performance warranty. The panel loses no more than 2.5% of its power in the first year and no more than 0.5% in the subsequent years. After 30 years it retains over 83% of its output.

honestly, i found these bifacial panels to be really effective. I’d say that they are a bit more expensive and take a bit more effort to set up, but you really feel the gain in power and they look nicer imo

Leave a review

the datasheet says 72 cells, but the description says 144??
It’s a 72-cell layout, but the cells are half-cut, so there are 144 of them. The size of a panel is the same as a 72-cell one.
is it chinese?
It is Chinese, yes.
Can i pair 10 of those with 5000W inverter?
Yes, you can
