6 FAQs about [How to calculate the bifaciality of solar cells]

How to calculate bifacial solar power output?

The general formula for determining the total energy generation of a bifacial solar panel is the sum of the energy output on the front side and the energy output on the rear side. However, as the energy output on the rear side is much more difficult to calculate, the total calculation of bifacial power output requires some industry innovation.

What is bifacial solar technology?

Therefore, we can say that bifacial technology is a relatively new development in solar panel design that presents both opportunities and challenges. Bifacial solar modules are modules that generate energy on both their front and rear sides, based on solar cells with two active sides.

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

Can a solar simulator be used to measure bifacial PV devices?

As described in IEC 60904-1-2, for single-sided illumination measurements of bifacial PV devices, a solar simulator (as defined in IEC 60904-9 ) with adjustable irradiance level has to be used for the I-V characterisation.

How to determine bifaciality coefficients of a PV device?

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.

Are bifacial PV modules better than monofacial solar panels?

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.
