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 (-0.290 %/°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 CS6.2-66TM-610 or Canadian Solar CS6R-450T?
According to our database: Canadian Solar CS6R-450T has higher module efficiency (23.00% vs 22.60%). See the full spec comparison and 30-year energy simulation above for a complete picture.
What is the efficiency of Canadian Solar CS6.2-66TM-610 and Canadian Solar CS6R-450T?
Canadian Solar CS6.2-66TM-610 has a module efficiency of 22.60%, while Canadian Solar CS6R-450T is 23.00%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does Canadian Solar CS6.2-66TM-610 use vs Canadian Solar CS6R-450T?
Canadian Solar CS6.2-66TM-610 uses TOPCon cells; Canadian Solar CS6R-450T uses TOPCon. 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 CS6.2-66TM-610 and Canadian Solar CS6R-450T?
Canadian Solar CS6.2-66TM-610 has a 30 years power warranty; Canadian Solar CS6R-450T 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.
