Trina Dual Glass Solar Panels
We believe Trina Duomax to be the best solar panel in New Zealand.
Trina Duomax is the only panel available that uses Dual Glass technology. Unlike plastic panels promoted by competitors, Dual Glass means both sides of the panel are composed of heat strengthened glass, giving it a maximum fire resistance rating plus improved strength against New Zealand winds, hailstones and earthquakes. The solar cells are fully encapsulated and protected from moisture and the outside air. They don't deteriorate in the same way that plastic panels do and hence they produce more solar power during their lifetime - an estimated 50 years.
Trina Duomax panels have done away with the old aluminium frames to make a smooth, streamlined appearance with brilliant aesthetic results and no need for electrical grounding, making for a fast and easy solar installation. Metal frames can cause issues with the silicon cells such as Potential Induced Degradation P.I.D and snail trails and short circuits in the silicon. By removing them it means the panels keep themselves clean through the natural action of wind and rain without the need to brush dust out of the frame corners.
The difference in appearance is a bit like a smart phone vs. a dumb phone from 20 years ago. Sleek, streamlined, modern.
Trina Duomax panels have a longer warranty than other panel types - 30 years guarantee on the output of the panels. They are highly resistant to UV deterioration or microscopic damage during transport or high wind conditions. They consistently score number 1 in several independent studies*.
