6 FAQs about [Power gain on the back side of bifacial cells]

Does bifacial PV module output decrease?

Initial works in this area shows a decrease in bifacial PV module output (bifaciality factor: 73%) when comparing a single PV module (108×26 cm 2) and a stack of 5 PV modules separated from each other 20 cm and placed above a white wall (85% reflectivity) .

What is a bifacial PV module?

Unlike conventional PV modules that convert only front-side irradiance into electrical power, bifacial modules convert both front- and back-side irradiance into electricity.

Is bifacial gain an input or a result?

Reality: Bifacial gain is not an input; it is a result. From the perspective of the owner’s engineer (OE), bifacial gain is not a simple input to a software model but rather the result of multiple design and engineering decisions related to the balance of system (BOS) components.

How can bifacial gain and system production be predicted?

In order to predict bifacial gain and system production, the software model used to predict plant performance needs to characterize the impacts of BOS design and engineering decisions. While design and engineering decisions have a major impact on bifacial gain, construction details are equally important.

Does bifacial module elevation affect BOS costs?

However, increasing the module elevation also can increase the BOS costs. Fig. 4. Maximum power gain versus elevation for a bifacial module of 1.63×0.87 m 2 (72 bifacial pseudo square c-Si solar cells) whose back efficiency at one sun illumination is 71% of the front, at fixed tilt of 30° (31°47′N, midday May 30th) and 50% ground reflectance .

Why are bifacial PV modules better than monofacial?

Due to the decrease in working temperature, bifacial PV modules are able to operate at lower temperature than monofacial ones, resulting in an increase in maximum power output.
