Influence 2:
The Height
Pitch
Influence 1:
The Albedo Factor
Tilt
3 Main influencers on bifacial gain:
1. Albedo factor „The brighter the background/underground (= the higher the Albedo factor), the better“.
2. The Height: „The higher the module from theunderground, the better“
3. The Tilt: „The steeper the tilt, the better“
