6 FAQs about [Double-glass module bifaciality]
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.
Should glass/glass PV modules have bifacial solar cells?
However, glass/glass PV modules with bifacial solar cells deliver extra power in outdoor settings due to absorption from the module's rear side. As a result, a glass/glass module structure with bifacial solar cells was recommended by since it can fully utilize the potential of bifacial solar cells.
What are the benefits of glass-glass configuration bifacial modules?
Our analysis identified the following benefits for glass-glass configuration bifacial modules: The polymer backsheet that traditional modules use is made from plastic with poor resistance to acid and corrosion. Prolonged exposure to air may bring about yellowing, cracking, degradation and chalking, etc.
What is bifacial glass technology?
Bifacial glass technology is the preferred material among manufacturers for the rear side cover of the modules. Some key advantages of the glass-glass structure are: Glass-glass modules can also be frameless, which helps eliminate the cost of an extruded aluminum frame. However, glass-glass models with frames have a lower risk of breakage.
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).
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.
