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-630 or Canadian Solar CS6W-585T?
According to our database: Canadian Solar CS6.2-66TM-630 has higher module efficiency (23.30% 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-630 and Canadian Solar CS6W-585T?
Canadian Solar CS6.2-66TM-630 has a module efficiency of 23.30%, while Canadian Solar CS6W-585T is 22.60%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does Canadian Solar CS6.2-66TM-630 use vs Canadian Solar CS6W-585T?
Canadian Solar CS6.2-66TM-630 uses TOPCon cells; Canadian Solar CS6W-585T 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-630 and Canadian Solar CS6W-585T?
Canadian Solar CS6.2-66TM-630 has a 30 years power warranty; Canadian Solar CS6W-585T 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.
