Price of double-glass bifacial 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.

What is a bifacial G-B module?

Bifacial G-B modules use a 3.2 mm-thick tempered glass on the front, delivering superior impact strength and durability in comparison to the 2 mm–2.1 mm thick heat-treated glass typically used in G-G modules. The glass used in PV modules generally has a UV transmittance of 40%-50%.

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.

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.

How are bifacial solar panels made?

There are two common methods for making bifacial solar PV modules: The first involves using glass layers on both the front and rear sides of the panel, referred to as “Glass-Glass PV Modules," "Double Glass PV Modules," or "Dual-Glass PV Modules."
