Canadian Solar Launches High-Power N-Type TOPBiHiKu CS6.2 Module Series with Up to 660 Wp Output

Canadian Solar Inc. announced the launch of its next-generation N-type TOPBiHiKu CS6.2module series, designed for both utility-scale and commercial & industrial (C&I) applications. Leveraging the latest TOPCon 2.0 cell technology, the new modules deliver up to 660 Wp of power output and a conversion efficiency of up to 24.4%. Global deliveries are scheduled to begin in August 2025.

The TOPBiHiKu CS6.2 series integrates several cutting-edge innovations to maximize energy yield and system value, including:

• Fine line printing: Reduces finger width by over 30%, decreasing shading and improving light absorption by 1% (absolute).
• Advanced firing process: Enhances contact quality and reduces recombination, increasing open-circuit voltage by 10 mV.
• Rear polysilicon optimization: Lowers parasitic absorption and current loss, achieving up to 90% bifaciality.
• Next-gen passivation: Minimizes emitter recombination, boosting efficiency by 0.1% (absolute) through improved voltage performance.
• Ultra-precise SMBB design: Reduces electrical resistance, improving overall energy output.

Engineered for high performance in diverse environments, the new module series features a temperature coefficient of -0.28%/°C, enabling up to 2% lower balance-of-system (BOS) costs and up to 5% reduction in Levelized Cost of Energy (LCOE) compared to current mainstream TOPCon modules.

Thomas Koerner, Corporate Senior Vice President of Canadian Solar, said, “We are pleased to announce our new N-type high power module. The CS6.2 module-series represents a significant leap forward in solar technology, delivering highest module efficiency, significantly lower LCOE, and greater sustainability for utility and commercial and industrial PV projects. With this launch, we reaffirm our commitment to innovation and customer centric developments as a leader of the global energy transition.”

With these enhancements, Canadian Solar continues to push the boundaries of solar innovation, helping customers achieve superior project economics and long-term energy performance.
