Shingled technology eliminates traditional ribbon connection with shingles connected in series. By removing the soldered ribbons, the active area of the module is improved and thermal stresses are reduced – resulting in exceptional efficiency and reliability over standard interconnections. Puma modules are based on the shingled technology which allow a higher cells density than standard half-cut modules.
Cells are cut in 5 or 6 pieces, the obtained “shingles” are assembled in strings by connecting front and rear edges of consecutive shingles with an Electrical Conductive Adhesive (ECA).
The ECA replaces the Copper Interconnection Ribbons usually soldered on solar cells, providing a flexible interconnection and avoiding the thermal/mechanical stresses on the Silicon – Copper interface.
