JinkoSolar has unveiled three new n-type solar module variants featuring tunnel oxide passivated contact (TOPCon) technology.

The new Tiger Neo Series includes 54-cell products with power outputs of up to 445 W and a maximum efficiency of 22.27%. The 72-cell panels in the line have a nominal power rating of 615 W and an efficiency rating of up to 23.23%. The line also includes larger 635 W modules with maximum efficiencies of 22.72%.

All of the products are based on 182 mm wafers, as with previous Tiger Neo products. JinkoSolar said that all of the panels have a temperature coefficient of -0.29% C and a bifaciality factor of 85%. They also feature a short circuit current of 13.93 A.

The new products based on 54 cells come with a 15-year product warranty and a 30-year performance warranty, while products based on 72 and 78 cells the product warranty is of 12 years.
