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 (-0.350 %/°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: Aptos Solar DNA-120-BF10-460W or Aptos Solar DNA-120-BF10-455W?
According to our database: Aptos Solar DNA-120-BF10-460 W has higher module efficiency (21.26% vs 21.03%). See the full spec comparison and 30-year energy simulation above for a complete picture.
What is the efficiency of Aptos Solar DNA-120-BF10-460W and Aptos Solar DNA-120-BF10-455W?
Aptos Solar DNA-120-BF10-460 W has a module efficiency of 21.26%, while Aptos Solar DNA-120-BF10-455 W is 21.03%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does Aptos Solar DNA-120-BF10-460W use vs Aptos Solar DNA-120-BF10-455W?
Aptos Solar DNA-120-BF10-460 W uses PERC cells; Aptos Solar DNA-120-BF10-455 W 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 Aptos Solar DNA-120-BF10-460W and Aptos Solar DNA-120-BF10-455W?
Aptos Solar DNA-120-BF10-460 W has a 30 years power warranty; Aptos Solar DNA-120-BF10-455 W 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 Aptos Solar DNA-120-BF10-460W and Aptos Solar DNA-120-BF10-455W bifacial panels?
Both Aptos Solar DNA-120-BF10-460 W and Aptos Solar DNA-120-BF10-455 W 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.
