The panels are made from PERC solar cells, which are more efficient than traditional photovoltaics.

The back contact technology of the Silfab Elite panels allows them to collect more solar energy than before. This allows them to reduce the impact of sunlight on their cells. This combination of solar cells and back contact technology helps improve the efficiency of the panels.
