Introducing Sonnex TBC Solar Panels: The Next Leap in High-Efficiency PV Technology


2025-06-12

Sonnex Energie is proud to unveil our next-generation TBC back contact solar panels, set for market release starting Q3 2025. Engineered for peak performance and long-term reliability, these new modules combine the strengths of TOPCon (Tunnel Oxide Passivated Contact) and IBC (Interdigitated Back Contact) cell technologies, achieving module efficiencies of up to 24%—among the highest in the industry today.

 

 

 

What is TBC?

TBC stands for Tunnel-Back Contact, an innovative cell design that fuses the advanced passivation of TOPCon with the aesthetic and performance benefits of back-contact structures. This hybrid approach eliminates front-side metal shading, enhances light absorption, and maximizes electrical performance.
