As we all know, the power generation of bifacial modules can use scattered light and emitted light of scattered light in addition to the surface reflected light of direct sunlight. Based on the power generation principle of bifacial modules, as an investor and developer of photovoltaic power plants, or want to build photovoltaic power plants with bifacial modules, the following design suggestions are worth looking at.

The power generation gain of the bifacial module can be roughly judged according to the surface albedo. The primary variable associated with bifacial gains is surface albedo, or the amount of solar radiation reflected by the ground (Stull, 1988). Surface albedo exhibits significant differences throughout regions and groundcovers, across the different seasons, and even throughout the day.

Surface Albedo: sand/concrete > land > grass > water, the approximate surface albedo is

1:Water surface: 5%~12%

2: Grass: 15%~25%

3: Dry land: 20%~23%

4: Cement floor: 20%~40%

5: Yellow sand: 20%~40%

6: Snow: 80%~85%
