Canadian Solar has launched its new TOPCon 3.0 solar panel, tailored for utility-scale power plants and C&I PV systems. With a power output of up to 670 W and a conversion efficiency of up to 24.8%, the new product is scheduled for global mass shipment starting in August 2026.
The module features a multi-cut technology based on large-format, 182-mm rectangular cells and enhanced light utilization, while maintaining a standard module size of 2,382 × 1,134 × 30 mm for optimum logistics and easy system integration.
Cell poly-patterned technology and optimized back-side design enable PV module bifaciality of up to 90%, delivering an additional 0.4%-0.5% system-level energy gain, Canadian Solar says.
Advanced passivation technologies on the cell edge and surface lower the PV module temperature coefficient to -0.26%/°C, improving PV system performance in high-temperature environments.
Together, these advanced cell and module technologies deliver high reliability and reduce degradation to ≤1% in the first year and 0.35% annually thereafter, ensuring over 88.85% output after 30 years, Canadian Solar claims.
For demanding conditions such as glare-sensitive, high-load, corrosive and dusty environments, the TOPCon 3.0 module portfolio can be equipped with anti-glare glass, IoT (Internet of Things)-enabled junction box and steel, composite or anti-dust frames, enhancing PV system safety and visibility.
“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,” said Dr. Shawn Qu, Executive Chairman and CEO of Canadian Solar.
