Packaging & Delivery Product Description

Bifacial PERC

. For a bifacial PERC cell, the Al back surface field is replaced by Al grid, hence render the majority of rear side transparent
which enable the cell to absorb light and generate electricity from both sides.

Front side performance equivalent to conventional low LID mono PERC:-High module conversion efficiency (up to 20.9%). -Better energy yield with excellent low irradiance performance and temperature coefficient. -First year power degradation<2%. Bifacial technology enables additional energy harvesting from rear side(up to 25%).

Glass/glass lamination ensures 30 year product lifetime ,with annual power degradation <0.45%,

1500v compatible to reduce BOS cost.

Solid PID resistance ensures by solar cell process optimization and careful module BOM selection .

Reduced resistive loss with

lower operating temperature.

Higher energy yield with lower operating temperature. Reduced hot spot risk with optimized electrical design and lower operating current.

Cell efficiency>22%,anti-LID,anti-PID,1st year degradation≤2%

Design for short frame without C side can reduce the shading caused by frame

Bifacial Power Generation:

The energy yield of bifacial module can be influenced by albedo, height of module, GCR and DHI etc. Installation height of
bifacial module is recommended to be higher than 1m. Shading from bracket and junction box should be avoided. At present, the power generation of bifacial module on fixed brackets and single axis tracker can be simulated with PVsyst. Investors can determine the DC/AC ratio of bifacial module system to minimize the LCOE.
