Yingli releases 435W n-type TOPCo solar panel with 22.28% efficiency



Yingli offers six versions of its 108-cell Panda 3.0 PRO modules, with powers ranging from 410 W to 435 W and efficiencies from 21.0% to 22.28%.

“With lighter materials and frames, the Panda 3.0 Pro 108 cell has the advantages of lightness and easy installation in addition to high power, high efficiency, high duplex and high reliability,” a company spokesperson said. pv magazine. “The product is more suitable for residential power plants and other distributed power plants.”

The 108-cell Panda 3.0 PRO modules are available in six versions with powers ranging from 410 W to 435 W and efficiencies from 21.0% to 22.28%. The breakdown voltage is 37.75 V to 38.69 V and the short-circuit current is 13.91 A to 14.22 A. The maximum system voltage is 1,500 V.

The dimensions of the panels are 1,722 mm x 1,134 mm x 30 mm and the weight is 24.8 kg. They have IP67 housing and 2 mm tempered glass. They have a temperature coefficient -0.30% per degree Celsius and operating temperature -40 C to 85 C.

The new products have a 30-year linear power warranty and a 12-year product warranty. The final output of 30 years is guaranteed to be at least 87.4% of the nominal output output.

“The new surface passivation system improved the open circuit voltage of the cell,” a company spokesperson said. “And the low-power laser splitting technology reduces cell shear losses.”

The modules are based on TOPCo’s 24.5% efficient cells with front laminated composite film passivation. This is said to enable the back tunnel oxide passivation contact technology to improve the open circuit voltage of the cells above 710 mV.

Yingli currently has a TOPCo cell capacity 5 GW. It should reach 10 GW next year and 15 GW in 2024. In August, it announced a 156-cell Panda 3.0 PRO module with a power output of up to 615 W.
