About product

Trina Solar 385W 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:

  • 385W frontside power output
  • 144 cell bifacial monocrystalline module
  • Bifacial gain up to 25%
  • up to 23.4% 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 385 Watts of power with 18.7% 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 424 Watts with 23.4% 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.

Really love that you added bifacial panels! My friend had a very positive experience with them so i was eager to try them out. They really feel much more powerful than standard ones.

The panel is cheap and it provides a lot of power so i don’t see a reason to complain. It might feel a bit flimsy, but it looks fine and the installer said that overall it was a fine choice by me.

do you ship to alaska?
Not at the moment.
how do you install them so that the backside works well?
Well, that’s a question for your installer. Generally, you make sure there is enough free space between the panel and the surface and you add a white membrane underneath the panel for higher reflectivity.
