Yingli Solar unveiled a new n-type bifacial solar module based on tunnel oxide passivated contact solar cells (TOPCon).
“Our n-type solar modules based on TOPCon cells can mainly be used in large-scale systems and harsh environments, due to their high bifaciality and high reliability,” a company spokesperson said. photo magazine.
The Chinese solar module maker said its 24.5% efficiency TOPCon cells are based on front-laminated composite film passivation, which enables rear tunnel oxide passivation contact technology improve the open circuit voltage of the cell by more than 710 mV.
“Backside micro-processing and ultra-thin tunnel passivation layer improve backside efficiency, as well as cell bifaciality to over 90%,” the spokesperson said.
The 156-cell Panda 3.0 PRO module is available in six versions, with powers ranging from 590W to 615W and efficiencies ranging from 22.11% to 22.0%. Its open circuit voltage is between 54.74 V and 56.44 V and the short circuit current is between 13.72 A and 14.12 A. The maximum system voltage is 1500 V.
The panel measures 2465mm x 1134mm x 30mm and weighs 35.0kg. It also has an IP67 casing and 2mm tempered glass. This has a temperature coefficient of -0.30% per degree Celsius and its operating temperature ranges from -40 C to 85 C.
The new products come with a 30-year linear power warranty and a 12-year product warranty. Degradation in the first year is said to be 1.0% and the final 30 year power output is guaranteed to be no less than 87.4% of the rated power output.
“Yingli’s TOPCon cell capacity will be 5 GW at the end of this year and will reach 10 GW next year and 15 GW in 2024,” the spokesperson explained. “All of these capabilities are located in Chinese manufacturing bases, including Hebei Province and Tianjin City. The production capacity of the modules corresponds to it.
