Technical FAQs 4

What are bifacial modules?

Since the light reaching the module’s rear side behaves differently than the light reaching the front side, bifacial modules must be understood in terms of “bifacial ratio” (i.e., the ratio of irradiance on the rear to that on the front) and “module bifaciality” (i.e., the ratio of the front and rear sides’ energy conversion efficiency).

Why do bifacial modules have glass panels?

Manufacturers tend to prefer glass panels on both the front and rear sides of a bifacial module because these designs tend to better transmit light and are more resistant to inclement weather, moisture permeation, corrosion, and more excellent mechanical load ability.

What are bifacial and monofacial solar cells?

Front and rear view of monofacial and bifacial photovoltaic (PV) modules . Bifacial solar cells encased in a glass/backsheet structure provide more power under standard test conditions (STC) than glass/glass PV bifacial modules.

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.
