Bifacial solar cell formula diagram
Performance Modeling and Testing of Bifacial PV Systems
The bifacial gain depends on three major factors: the system geometry, the ground albedo, and the module bifaciality. PV modeling software takes care of (most of) the system-geometry effects. The albedo should be measured at the project site. Module manufacturers are on a learning curve. Sample testing per IEC 60904-1-2 is recommended.

How bifacial PV module is calculated?
ackside simultaneously. As a result, the total produced energy of the Bifacial PV Module is calculated by the sum of energy from the frontside and the backside of the module. The bifacial output power can be viewed as a monofacial module producing energy from the total sum of sunlight exposed to the frontside and the backside
What is a bifacial solar cell?
Instead, a bifacial solar cell is designed in such a way that the cell will produce a photocurrent when either side, front or rear, is illuminated. BSCs and modules (arrays of BSCs) were invented and first produced for space and earth applications in the late 1970s, and became mainstream solar cell technology by the 2010s.

What are bifacial modules?
Since the light reaching the module’s rear side behaves differently than the light reaching the front side, bifacial modules must be understood in terms of “bifacial ratio” (i.e., the ratio of irradiance on the rear to that on the front) and “module bifaciality” (i.e., the ratio of the front and rear sides’ energy conversion efficiency).
