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.
