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 CS7N-650MS or Canadian Solar CS6L-465MS?
According to our database: Canadian Solar CS6L-465MS has higher module efficiency (21.50% vs 20.90%). See the full spec comparison and 30-year energy simulation above for a complete picture.
What is the efficiency of Canadian Solar CS7N-650MS and Canadian Solar CS6L-465MS?
Canadian Solar CS7N-650MS has a module efficiency of 20.90%, while Canadian Solar CS6L-465MS is 21.50%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does Canadian Solar CS7N-650MS use vs Canadian Solar CS6L-465MS?
Canadian Solar CS7N-650MS uses PERC cells; Canadian Solar CS6L-465MS 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 CS7N-650MS and Canadian Solar CS6L-465MS?
Canadian Solar CS7N-650MS has a 25 years power warranty; Canadian Solar CS6L-465MS has a 25 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.
