In the light of the results obtained, the power bifaciality coefficient of a photovoltaic module, measured experimentally in real operating conditions and translated to STC, matches relatively well the value indicated by the manufacturer in its datasheet.
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 background described above. Using these measurements, bifacial parameters can be defined.
A novel development is the advent of bifacial PV modules that enhance energy production by converting incident irradiance on the rear side of the module into electricity. Bifacial solar photovoltaics (PV) cells as a promising technology convert the photons from albedo and incident irradiance into electricity [ 2 ].
Bifaciality of photovoltaic (PV) modules has demonstrated great potential to increase the output power of modules with relatively low additional cost . Bifacial PV modules can potentially increase energy yield of a PV system by 3 – 15 % compared to monofacial PV modules for the same available area.
Compared with monofacial PV modules, energy yields of around 10% higher (or even more) from bifacial modules in the field have been consistently reported by various parties [2,3]. Such increases in yield can considerably reduce the levelized cost of energy. Bifacial PV technology is not a new concept in the PV community.
