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.

FREE WEBINAR -This special webinar will take a deep dive into the latest PV ModuleTech Bankability Ratings pyramid, capturing the relative bankability status of the top 70-80 PV module suppliers globally. In addition to revealing the latest ranking of global PV module suppliers, PV Tech’s Head of Research, Finlay Colville, will show the depth of analysis and commentary included within the report for module suppliers. A key output from the webinar will be to learn which PV module suppliers have moved up the rankings pyramid in recent years and why this growth has been achieved. Conversely, some of the companies that have fallen down the rankings will be discussed, in particular those suffering from market-share losses and financial problems.
