Canadian Solar has introduced its 3rd generation TOPCon modules, reaching a power output of 670 W and 24.8% efficiency
The module features high-power-density, high bifaciality, and low temperature coefficient
CSI also offers application-specific variants for glare-sensitive, high-load, corrosive, and dusty environments
Leading solar module manufacturer Canadian Solar Inc. (CSI) has launched a high-power-density module based on the 3rd generation of its TOPCon module platform, called TOPCon 3.0. The company claims the module can reach a maximum efficiency of 24.8% and a maximum rated power output of 670 W. It highlights high power density, high bifaciality, and low temperature coefficient as the key performance features of this module.
Based on large-format rectangular multi-cut cells, the module achieves a high power density while maintaining the standard dimensions of 2,382 × 1,134 × 30 mm. The 2 mm dual-glass module achieves a bifaciality of up to 90% through cell poly-patterned technology and an optimized backside design, according to the company. It has a temperature coefficient of -0.26%/°C, which the company attributes to advanced edge and surface passivation technologies. The module has a first-year degradation of ≤1% and an annual degradation of 0.35% thereafter. The module is backed by a 12-year product warranty and a 30-year performance warranty.
"With the launch of our TOPCon 3.0 module, we continue to advance high-efficiency PV technology, delivering up to 1.6% higher energy yield and up to 1.4% lower LCOE, translating into stronger lifecycle value and more predictable long-term returns for our global partners," says Shawn Qu , Executive Chairman and Chief Technology Officer of Canadian Solar.
CSI also offers the module with anti-glare glass for glare-sensitive applications, with IoT-enabled junction boxes and steel, composite, or anti-dust frames for different installation environments.
The company plans to begin global commercial shipments of the high-power-density module in August 2026. CSI showcased this module at Intersolar Europe 2026.
