Electrical characteristics with different rear side power again (reference to 445W front)

 

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.

Material details

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.

High Energy Yield

Outstanding low irradiance performance, low power-temperature coefficient, low operating temperature, all these technologies lead
to a high energy yield.

 

Warranty

Based on the advanced mono wafer and anti-LID technology, LONGi offers a first-year power warranty of ≥98% for PV modules.
