Green Tech Leader Canadian Solar: Canadian Solar Unveils Low-Carbon Modules with Industry-Leading CO2 Footprint

Kitchener (Canada) - Canadian Solar Inc. has introduced its new generation of Low Carbon (LC) modules, which feature a carbon footprint of just 285 kg CO₂ equivalent per kilowatt - one of the lowest values worldwide among silicon-based solar modules. With this, the company sets new benchmarks in sustainable solar manufacturing.

The modules combine advanced wafer innovations with heterojunction (HJT) cell technology and are designed for utility-scale, commercial, and industrial applications. They offer power output of up to 660 watts peak and module efficiency of up to 24.4%. Shipments began in August 2025.

Canadian Solar achieved the emissions reduction through several technological advancements:

A 20% higher material yield in ingot production reduces emissions by around 9.7%.

Thinner wafers - 110 micrometers compared to the previous 130 to 135 micrometers - cut silicon consumption and CO₂ emissions by up to 5.5%.

The HJT cell manufacturing process has been simplified from 10–13 steps to just four.

Operating temperatures have been reduced from over 900°C to below 230°C.

Overall, production of the LC modules saves 8.8% to 10.7% energy compared to common TOPCon and back-contact (BC) modules. The carbon payback time of the new modules is approximately 11% shorter than that of conventional N-type silicon modules.

“We are proud to introduce our new environmentally friendly, low-carbon modules, marking a key milestone in sustainable solar manufacturing,” said Thomas Koerner, Corporate Senior Vice President of Canadian Solar.

The modules are being showcased at RE+ 2025 from September 9 to 11 in Las Vegas.

Canadian Solar shares declined by 2.3% over the first three trading days this week, closing at €9.26 on September 10, 2025 (Stuttgart Stock Exchange).
