[PDF Version]FAQs about Differences between bifacial single-glass modules and bifacial double-glass modules
Are bifacial double-glass modules a good choice?
There has been a noteable shift from the initial single-facial single-glass modules to bifacial double-glass modules. Double-glass modules, with their performance in the face of salt mist, high temperatures and high humidity, have won the market's favour. However, this trend is not without its risks.
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 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%.
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."
