Should bifacial panels have double/dual glass?

These days, many bifacial panel designs incorporate double/dual glass at the rear of the modules. Glass-glass panels seems to better transmit light and are more resistant to unpredictable weather, moisture, corrosion, and have good mechanical load capacity.

What is a bifacial solar module?

The front of a bifacial solar module is covered with a protective glass and the rear side may be made of either glass or transparent polymer backsheet that allows sunlight to pass through. This stands in contrast to conventional solar panels which have opaque backsheets.

What are bifacial modules?

Bifacial modules also have an additional characteristic, bifaciality, which is the ratio of rear power to front power. P-PERC cells have a bifaciality of 70% while HJT boasts over 90% bifaciality. Bifacial models such as the HJT 72 cell design from Sunpreme has a 390 W power rating and bifaciality of 95%.

Why are n-type bifacial modules so popular?

Interest in N-type bifacial modules has rapidly increased due to their ability to generate more power than conventional P-type bifacial thanks to their higher bifacial factor, lower degradation, lower temperature coefficient in addition more energy density and power class.

How long does a glass-glass bifacial module last?

Besides， glass-glass bifacial modules could provide a minimum of 30 years thanks to the better resistance to corrosion, abrasion, extreme weather, shock, and vibration that ensures N-type module safety during production, transport, installation and long-term power generation and prevents new invisible cell cracking

How are bifacial solar cells encapsulated?

Bifacial solar cells can be encapsulated in modules with either a glass/glass or a glass/ transparent backsheet structure.
