Basic Parameters
Product Features
Low attenuation
The first year attenuation is less than 1.0% with a linear attenuation of 0.4% per year for 30 years
Double sided power generation
The gain of double-sided power generation increases with the back light exposure,reaching up to 25% significantly reducing LCOE.
High power
Applying N-type multi-busbar half cut technology to improve energy density and bring higher output power.
Better power generation performance
The series parallel design reduces the series resistance Rs and reduce sinternal electrical performance losses
