Canadian Solar Unveils 660 Wp N-Type Module At 24.4% Efficiency

Canadian Solar, a solar technology and renewable energy company launched its new N-type high-power TOPBiHiKu CS6.2 module series. These modules are for both Utility and Commercial & Industrial Systems. Based on the latest TOPCon cell technology, the module delivers a maximum power output of up to 660 Wp and a conversion efficiency of up to 24.4%. Canadian Solar is beginning its global deliveries in August 2025.

Canadian Solar’s new N-type high power module enhances project economics, offering up to 90% bifaciality, an optimized temperature coefficient (-0.28%/°C) which enables up to 2% lower balance of system costs, and up to 5% reduction in LCOE compared to today’s standard TOPCon PV modules.

TOPCon 2.0 module series

The TOPCon 2.0 module series aims to maximize energy yield and system value to increase system performance and output with the following key technical innovations:

• Fine line printing: Reduces finger width by over 30%, minimizing shading effect and improving incident light utilization by 1% (absolute).
• Advanced firing process: Improves contact resistance and reduces carrier recombination in the contact area, increasing open-circuit voltage by 10 mV.
• Rear polysilicon optimization: Minimizes parasitic absorption and reduces current loss, achieving bifaciality of up to 90%.
• Next-gen passivation: Reduces emitter recombination losses by up to 20%, increasing cell efficiency by 0.1% (absolute) via open-circuit voltage optimization.
• Ultra-precise SMBB design: Minimizes electrical resistance and associated power losses.

Thomas Koerner, Corporate Senior Vice President of Canadian Solar, remarked, “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 the 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.”

The TOPCon 2.0 module series will be showcased at Intersolar Europe from May 7 to 9, in Munich Germany.
