Basic Parameters
Product Features
Low risk of hot spots
Adopting new generation cell technology and optimizing circuit design to achieve better temperature coeficient and thermal resistance.
High energy density
Adopting large-sized and highly efficient cells,applying efficiency enhancing packaging materials and half cut technology to improve power output.
Lower electrical losses
The multi-busbar design effectively reduces the impact of hidden cracks and broken and the half cut cell structure effectively reduces the impact of shadow occlusion.
Double sided power generation
The gain of double-sided power generation increases with the back light exposure,reaching up to 25% significantly reducing LCOE.
