Bi-facial solar panels produce power from both sides (front & back). The panel front side capture direct sun light while backside capture Albedo which can boost production by up to 30% based on surface reflectance. Below table indicating the relation between site ground material type & amount of Albedo reflected on the backside of the panels :
One of the key factors for the success of the bi-facial panels is artificial intelligent based solar tracking system which decide best operational angle for maximum gain, also panels height plays an important role in determining the amount of light reflected on the backside which will be different from one site to another and must be accurately calculated. Below video showing installation recommendations:
