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.
