How to Calculate the Gain in Bifacial Modules
Bifacial gain is a crucial metric for evaluating the benefits of bifacial PV technology. By optimizing system design (albedo, elevation, spacing), the bifacial gain can be 10%-30% or more,

Bifacial gain is a variable, real-world result that depends on that factor plus site conditions (e.g., a module with a 70% factor might achieve a 15% gain on a white roof but only an 8% gain over grass).
These innovative modules capture sunlight from both sides, potentially boosting energy production by 10-30% in optimal conditions compared to standard panels. In typical installations,
During the project design phase, the engineer of record must determine a percentage of bifacial gain that it will use for sizing conductors and overcurrent protection. As with many other engineering
Models like SAM, PVSyst and Bifacial_Radiance can assist with system design and power estimation. • 1-axis tracker validation is underway at NREL, showing good initial match with model, and energy
Relevant reliability and safety tests are discussed, with additional modifications and suggestions for bifacial PV modules.
This additional performance gain is characterized by the bifaciality factor (or coefficient) which quantifies the power produced by the rear face relative to the front face.
The simulation results reveal that the implementation of bifacial solar modules on rooftops within Australia can result in energy yield gains of up to 22.6%. These findings demonstrate the
In order to determine the bifaciality coefficients of a PV device, the main I-V characteristics of the front and the rear sides must be measured at STC, using the requirements for the non-irradiated
Results revealed significant non-uniformity in rear-side irradiance, with a 32% variation between the lower edge and the centre of the bPV module.
