Trina Solar introduces the TOPCon solar panel series for roof level solar cells



Trina Solar says its new TOPCon solar panel combines a double glass design with n-type technology. Its efficiency ranges from 20.8% to 22.3% and output power between 415 W and 445 W.

“The new module series is suitable for both residential and C&I applications,” said company spokesman Michael Katz pv magazine. “The novelty of the new product consists of the combination of double glass design and n-type technology.”

The company offers the panel in two versions – a monofacial module with a white backplate and a bifacial product with a transparent backplate.

“The single-face NEG9R.28 features white back encapsulation for maximum output power, with up to 445 Wp and 22.3 percent efficiency,” the manufacturer said. “On the contrary, the transparent NEG9RC.27 is the preferred choice for high-end aesthetic applications, for example residential roofs, where the array would disappear completely optically. The front side power of this bifacial module is 435 Wp with an efficiency of 21.8%.

Trina Solar offers five versions of the NEG9R.28 products, ranging from 425 W to 445 W and power conversion efficiencies of 21.3% to 22.3%. Their open-circuit voltage ranges from 50.9 V to 52.6 V and short-circuit current from 10.56 A to 10.71 A. Boards measure 1762 mm x 1134 mm x 30 mm and weigh 21.1 kg.

The NEG9RC.27 modules are available in five versions with a power of 415 W to 435 W and an efficiency of 20.8 to 21.8%. Their open circuit voltage ranges from 50.1 V to 51.8 V and short circuit current from 10.50 A to 10.64 A. They measure 1762 mm x 1134 mm x 30 mm and weigh 21.1 kg.

The products can be used with a maximum system voltage of 1500 V and are built with IP 68 enclosures. They have temperature coefficient -0.30% per C and operating temperature -40 C to 85 C.

The panels have a 25-year product warranty and a 30-year performance warranty. The degradation in the first year is claimed to be 1.0% and at the end of 30 years the power is guaranteed to be at least 87.4% of the nominal output power.

“Both types have an area of ​​just under two square meters and a black aluminum body,” the manufacturer said.

“In terms of installation, the Vertex S+ is very compatible with other BOS components,” explained Trina Solar.

It offers a variety of mounting methods, including short side and long side mounting, crossbar, split rail and sliding mounting. With its short-circuit current of 10.7A, it is also compatible with more than 99% of common inverters on the market, as confirmed by a comprehensive compatibility analysis.
