Is N-Type TOPCon the Most Advanced Solar Panel Technology in mass production?



What's Leading the Pack in Mass Production?

1. N-Type TOPCon

2. Heterojunction (HJT)


Summary Table

Technology Mass Production Scale Typical Efficiency in Production Relative Production Efficiency
N-Type TOPCon Very high; expected to lead overall growth ~26 % (commercial reports) Leading in production scaling and cost-effective upgrading from PERC
HJT (Heterojunction) Rapidly growing, but smaller share than TOPCon ~25 % average; higher peaks possible Highest commercial efficiency, but higher manufacturing complexity

Verdict

Yes—N-Type TOPCon is currently one of the most advanced and widely deployed silicon-based solar panel technologies in mass production, thanks to its high efficiency, compatibility with existing manufacturing lines, and cost-effectiveness.

All ROCKSOLAR Solar panels are N-Type TOPCon solar panels.
