Advantages

Up to 630 W
High power per module for a lower levelised cost of energy (LCOE).
Bifacial module
80 ± 5 % bifaciality: the rear side adds yield over bright surfaces.
Low degradation
1 % in the first year and 0.4 % per year, 87.4 % power after 30 years.
TÜV SÜD certified
The 620–630 W classes are certified to IEC 61215 and IEC 61730.
