Understand The Technology
Bifacial Power Generation
Double- glass modules are able to absorb sunlight from two directions due to their double-sided design, thus increasing the efficiency of power generation. Under ideal conditions, double-glazed modules can generate 5% to 25% more power compared to single-glazed modules.
Reduced Hot Spot
With the use of multi-cut cells, the current is lowered, reducing localized overheating caused by current concentration. The glass backsheet has better heat dissipation performance, effectively reducing hot spots.
12- Year Warranty
Adopting glass backsheets with excellent waterproof performance effectively prevents water vapor from eroding the internal materials of the modules. This significantly reduces power loss and extends the service life of the module to about 12 years.
