New Tongwei modules boost bifaciality toward 90%

Tongwei showcased its new TNC 3.0 module series at The smarter E 2026 in Munich, along with a new module variant that boosts the bifaciality of the company’s modules close to 90%. In an interview at the event, the company’s Director of Product & Technology, Zander Yuan, said peak power of the TNC 3.0 module can reach up to 770 W, with maximum efficiency close to 24.8%. He says the modules also offer clients the flexibility to upgrade their systems from 1500 V to 2000 V.

At the event, Tongwei offered demonstrations of how the BIFIMAX module variant improves bifaciality compared with standard modules. Yuan explained the cell level and module level technological developments in the variant that contribute to the overall gains in bifaciality.

The BIFIMAX versions of the TNC 3.0 modules are already in mass production. Yuan says clients using this flagship product are already seeing generation gains of 1.5-2%, which translates to better LCOE. He adds that the new technologies will also help client significantly reduce their capital expenditures.
