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 CS6.2-66TB-605 or Canadian Solar CS6.2-66TB-630?
According to our database: Canadian Solar CS6.2-66TB-630 has higher module efficiency (23.30% vs 22.40%). See the full spec comparison and 30-year energy simulation above for a complete picture.
What is the efficiency of Canadian Solar CS6.2-66TB-605 and Canadian Solar CS6.2-66TB-630?
Canadian Solar CS6.2-66TB-605 has a module efficiency of 22.40%, while Canadian Solar CS6.2-66TB-630 is 23.30%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does Canadian Solar CS6.2-66TB-605 use vs Canadian Solar CS6.2-66TB-630?
Canadian Solar CS6.2-66TB-605 uses TOPCon cells; Canadian Solar CS6.2-66TB-630 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 CS6.2-66TB-605 and Canadian Solar CS6.2-66TB-630?
Canadian Solar CS6.2-66TB-605 has a 30 years power warranty; Canadian Solar CS6.2-66TB-630 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 CS6.2-66TB-605 and Canadian Solar CS6.2-66TB-630 bifacial panels?
Both Canadian Solar CS6.2-66TB-605 and Canadian Solar CS6.2-66TB-630 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.
