What it means on a roof
Thirty years of production
Each panel's own declared degradation curve, at 1,200 kWh/kWp a year
Same temp coeff. for both panels (-0.340 %/°C), so a warmer roof scales both curves by the same factor: the totals fall together and neither panel gains on the other.

Questions about this pairing
Which panel is better: Canadian Solar CS7L-610MB-AG or Canadian Solar CS7N-655MB-AG?
According to our database: Canadian Solar CS7L-610MB-AG has higher module efficiency (21.60% vs 21.10%). See the full spec comparison and 30-year energy simulation above for a complete picture.
What is the efficiency of Canadian Solar CS7L-610MB-AG and Canadian Solar CS7N-655MB-AG?
Canadian Solar CS7L-610MB-AG has a module efficiency of 21.60%, while Canadian Solar CS7N-655MB-AG is 21.10%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does Canadian Solar CS7L-610MB-AG use vs Canadian Solar CS7N-655MB-AG?
Canadian Solar CS7L-610MB-AG uses PERC cells; Canadian Solar CS7N-655MB-AG uses PERC. Modern n-type technologies (TOPCon, HJT, BC) typically deliver higher efficiency and lower degradation compared to older PERC (p-type) cells.
What is the warranty on Canadian Solar CS7L-610MB-AG and Canadian Solar CS7N-655MB-AG?
Canadian Solar CS7L-610MB-AG has a 30 years power warranty; Canadian Solar CS7N-655MB-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.
Are Canadian Solar CS7L-610MB-AG and Canadian Solar CS7N-655MB-AG bifacial panels?
Both Canadian Solar CS7L-610MB-AG and Canadian Solar CS7N-655MB-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.
