Bifaciality Warranty for solar Modules

4 FAQs about Bifaciality Warranty for solar Modules

What is the difference between bifacial and monofacial solar panels?

In most cases, bifacial solar panels are single-junction panels, and their absorption or photovoltaic layer is composed of the same materials, arranged in a similar architecture as in monofacial panels. The key difference between typical bifacial and monofacial panels lies in their backsheet.

What does bifaciality mean on solar panels?

First comes the term you might have spotted on the spec manual of these panels: 'bifaciality'. It refers to their ability to generate electricity from both sides. This characteristic is quantified by the 'bifaciality factor,' which is the ratio of the efficiency of the rear side to that of the front side under the same irradiance conditions.

How to use bifaciality of solar cells?

Another way to use bifaciality of solar cells is to install them vertically, so that the sides are facing east and west. This installation provides two-humped production profile, where the electricity production peaks in the morning and in the evening.

What is the efficiency of bifacial solar cells?

Efficiency of solar cells, defined as the ratio of incident luminous power to generated electrical power under one or several suns (1 sun = 1000W/m 2), is measured independently for the front and rear surfaces for bifacial solar cells.
