The new product uses N-type TOPCon technology and is fully enhanced in performance, power, Energy Density and reliability.
The mass production efficiency of Sunket N-type TOPCON Solar cells has reached 24.5%, the bifacial ratio of modules is up to 85%, and the additional power generation gain has increased by more than 3%. In 2022, Sunket will continue to focus on improving the efficiency of mass production of batteries, leading the efficiency and economy of TOPCon Series products to a new high, and bringing customers higher installed capacity.
Our TOPCon Solar Panels use 16BB N-type Mono Solar Cells, SKT420~430M10
Solar Cells: 182mm 108cells

Quality Control
100% digital workshop
each step will be recorded and included in the mes system. automatic production process, effectively avoid human error, ensure the entire production process from raw material inspection to packaging online monitoring, and save it for later use.
100% external assessment
before and after lamination, intelligent alarm and stop mechanism in case of any deviation or errors.
100% EL testing
before and following lamination, twice testing ensure no micro crack monitoring before final inspection. continuous line monitoring and video/photo record for each cell and panel.
100% IV testing
after lamination, conduct electrical performance testing. simulate the real sunlight and test the voltage and current of each solar panels to ensure the efficiency.
