High Output per Module
Up to 640 W from a single panel reduces module count, BoS cost, and installation time on large projects.
Utility / Projects – TNC 2.0
630W Utility-Scale Bifacial N-Type
High-output TNC 2.0 modules for solar farms and large utility projects. Fewer modules per megawatt, streamlined logistics, and best-in-class durability – engineered to deliver predictable yield at project scale.

Features and Benefits
TNC 2.0 N-Type Cells
The next generation of Tongwei Solar cell technology delivers higher efficiency, low-light gain, and stronger high-temperature performance.
Bifacial Energy Yield
80 +/- 5% bifaciality coefficient – significant rear-side energy gain for tracker and ground-mount installations.
Dual Glass Durability
Heat-strengthened glass front and rear protects against moisture ingress and mechanical stress over decades of operation.
Built for Project Scale
Streamlined logistics: fewer modules per pallet, fewer pallets per container, less handling on site.
Tier 1 Manufacturer
TUV Rheinland-verified vertically integrated supply chain – from polysilicon refining to finished module assembly.
