Advantages of double-glass bifacial modules

Why are glass-glass bifacial modules becoming more popular?

Due to their better reliability, glass-glass bifacial configurations have a larger portion of the worldwide bifacial module market share. Glass shortages, weight concerns for larger format modules, and decreasing prices for transparent backsheets have caused some manufacturers to switch to a glass-transparent backsheet structure.

Why are bifacial glass-backsheet modules becoming more popular?

In recent years, an increasing number of module manufacturers have shifted towards transparent backsheets due to their numerous advantages over traditional glass modules. Bifacial Glass-Backsheet (G-B) modules are 17% lighter than Glass-Glass (G-G) modules.

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.

Do bifacial modules come with frames?

As a result, most glass-glass modules come with frames in place. Compared with standard glass backsheet technology, framed modules with two layers of glass are heavier. Therefore, transparent backsheets are a solution for a lighter bifacial module. A more lightweight module means less cost on transportation, labor, and trackers whenever applicable.

Why should you choose a dual glass module?

Prolonged exposure to air may bring about yellowing, cracking, degradation and chalking, etc. In contrast, the glass found in our dual glass modules is a kind of inorganic material with relatively superior weather resistance, which considerably improves the module's reliability.

Why is bifacial glass better than tempered glass?

Owing to tempered glass having higher impact strength, the bifacial TB has lower risk if used in regions prone to weather conditions such as hail. The bifacial DG has a symmetrical structure, with the glass on each side contributing to its mechanical strength, providing it with a higher wind and dynamic mechanical load.
