N type monocrystalline bifacial dual glass solar panel / 320W / 60cells / 20V
Main Features
Dual glass design removes the possibility of potential induced degradation (PID) and the panel can withstand high humidity, high temperatures, sandstorms, ultraviolet and corrosion, all of which makes the dual glass module can be deployed in more harsh environment.
1. High power output
30 year linear performance warranty, more than 30% additional power gain.
2. Zero LID & PID
No LID, more power generation.
No PID, stable power generation.
3. Fire safety performance
Higher fire safety class to minimize fire risks.
4. Outstanding module performance
Higher power output, even under low light conditions.
Excellent low irradiation performance and below -0.38% /℃ temperature coefficient of Power.
5. Wider applications & more flexible installed angle
No water-permeability and high wear-resistance, can be widely used in high-humid, strong wind&sand areas and not limited to traditional slope installation.
