Tongwei has developed two new PV module lines based on n-type monocrystalline cells made with tunnel oxide passivated contact (TOPCon) technology.

The modules are based on G12 wafers and the company's TNC cell technology. It said it achieved a power conversion efficiency of 26.1% in cell production.

The TWMNH66-HS, the largest line, offers module versions with power outputs from 605 W to 625 W and efficiency ratings from 22.4% to 23.1%. They feature an open-circuit voltage between 47.60 V and 48.40 V, and a short-circuit current of 15.80 A to 16.0 A. The modules measure 2,382 mm x 1,134 mm x 35 mm and weigh 29 kg.

The TWMNH48-HD, the smallest series, includes five panel versions with an output of 435 W to 455 W and efficiency from 21.8% to 22.8%, featuring open-circuit voltage between 34.49 V and 35.21 V, and short-circuit current of 15.90 A to 16.10 A. The panels measure 1,762 mm x 1,134 mm x 30 mm and weigh 20.9 kg.

Fabricated with 3.2 mm anti-reflective-coated tempered glass and an IP68 enclosure, both panel series from Tongwei can operate with a system voltage of 1,500 V and endure temperatures between -40 C and 85 C, featuring a temperature coefficient of -0.30% per degree Celsius.

Tongwei provides a 12-year product warranty, a 30-year power output guarantee, and an annual linear degradation of 0.40% over 30 years, with degradation capped at 1.0% in the first year.
