Active backside provides high efficiency

The frontside of Duomax Twin puts out 395 Watts of power with 19.2% 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 494 Watts with 24.1% 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.

I was really worried about the condition of the panels and what I would do if they arrived broken. Luckily it didn’t happen, panels are in good condition, so my experience with the shop has been only positive.

The service was top notch. The panel is fine, good output, okay quality, it’s just that the warranties don’t really impress me, so i’m not ready to give it 5 out of 5.
