Canadian Solar Unveils 660 Wp TOPCon Module for Utility and C&I Systems

Canadian Solar Inc.  announced the launch of its new N-type high power TOPBiHiKu CS6.2 module series for both Utility and Commercial & Industrial Systems.

Based on the latest TOPCon cell technology, the module delivers a maximum power output up to 660 Wp and a conversion efficiency of up to 24.4 percent. Canadian Solar is beginning with its global deliveries in August 2025.

The TOPCon 2.0 module series integrates cutting-edge innovations to maximize energy yield and system value for maximum system performance and output with the following key technical innovations: fine line printing reduces finger width by over 30 percent, minimizing shading effect and improving incident light utilization by 1 percent (absolute); an 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 percent; next-gen passivation reduces emitter recombination losses by up to 20 percent, increasing cell efficiency by 0.1 percent (absolute) via open-circuit voltage optimization; and ultra-precise SMBB design minimizes electrical resistance and associated power losses.

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

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 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."
