Questions about this pairing
Which panel is better: Aptos Solar DNA-144-BF26-450W or Aptos Solar DNA-120-MF10-460W?
According to our database: Aptos Solar DNA-120-MF10-460 W has higher module efficiency (21.26% vs 20.70%); Aptos Solar DNA-144-BF26-450 W tolerates heat better (temp coeff -0.320%/°C vs -0.350%/°C). See the full spec comparison and 30-year energy simulation above for a complete picture.
What is the efficiency of Aptos Solar DNA-144-BF26-450W and Aptos Solar DNA-120-MF10-460W?
Aptos Solar DNA-144-BF26-450 W has a module efficiency of 20.70%, while Aptos Solar DNA-120-MF10-460 W is 21.26%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does Aptos Solar DNA-144-BF26-450W use vs Aptos Solar DNA-120-MF10-460W?
Aptos Solar DNA-144-BF26-450 W uses PERC cells; Aptos Solar DNA-120-MF10-460 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-144-BF26-450W and Aptos Solar DNA-120-MF10-460W?
Aptos Solar DNA-144-BF26-450 W has a 30 years power warranty; Aptos Solar DNA-120-MF10-460 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-144-BF26-450W and Aptos Solar DNA-120-MF10-460W bifacial panels?
Aptos Solar DNA-144-BF26-450 W is bifacial (captures light from both faces); Aptos Solar DNA-120-MF10-460 W is monofacial. Bifacial panels work best on ground mounts or raised structures with a light-coloured surface underneath.
