The company currently has production bases in Wuxi, Changzhou, Chuzhou and Suzhou, with an annual cell capacity production of 16.5GW and a module production capacity of 25GW annually.

Suntech’s smart factory will be able to produce 182mm (M10) and 210mm (M12) cells for the production of n-type TOPCon modules.

Moreover, the PV module manufacturer is among several Chinese manufacturers who recently announced an increase in production of n-type TOPCon modules with module manufacturers Trina Solar and DAS Solar also betting on the technology.

Recently PV Tech Premium explored the levelised cost of energy for different technologies of n-type modules including TOPCon, passivated emitter and rear cell (PERC) and heterojunction.
