Canadian Solar CS6.2-66TB-615 vs Canadian Solar CS7N-730TB-AG

Q: Which panel is better: Canadian Solar CS6.2-66TB-615 or Canadian Solar CS7N-730TB-AG?

According to our database: Canadian Solar CS7N-730TB-AG has higher module efficiency (23.50% vs 22.80%). See the full spec comparison and 30-year energy simulation above for a complete picture.

Q: What is the efficiency of Canadian Solar CS6.2-66TB-615 and Canadian Solar CS7N-730TB-AG?

Canadian Solar CS6.2-66TB-615 has a module efficiency of 22.80%, while Canadian Solar CS7N-730TB-AG is 23.50%. Higher efficiency means more electricity from the same roof area - useful when space is limited.

Q: What cell technology does Canadian Solar CS6.2-66TB-615 use vs Canadian Solar CS7N-730TB-AG?

Canadian Solar CS6.2-66TB-615 uses TOPCon cells; Canadian Solar CS7N-730TB-AG uses TOPCon. Modern n-type technologies (TOPCon, HJT, BC) typically deliver higher efficiency and lower degradation compared to older PERC (p-type) cells.

Q: What is the warranty on Canadian Solar CS6.2-66TB-615 and Canadian Solar CS7N-730TB-AG?

Canadian Solar CS6.2-66TB-615 has a 30 years power warranty; Canadian Solar CS7N-730TB-AG has a 30 years power warranty. The power warranty guarantees a minimum percentage of rated output at the end of the warranty period (typically 80-87%). Product (materials) warranties are usually shorter.

Q: Are Canadian Solar CS6.2-66TB-615 and Canadian Solar CS7N-730TB-AG bifacial panels?

Both Canadian Solar CS6.2-66TB-615 and Canadian Solar CS7N-730TB-AG are bifacial - they capture reflected light from the ground, which can add 5-15% more annual energy on ground-mount or elevated rooftop installations with a light surface beneath.
