Questions about this pairing
Which panel is better: Aptos Solar DNA-120-BF26-365W or Aptos Solar DNA-120-BF10-450W?
According to our database: Aptos Solar DNA-120-BF10-450 W has higher module efficiency (20.79% vs 20.01%); Aptos Solar DNA-120-BF10-450 W tolerates heat better (temp coeff -0.350%/°C vs -0.360%/°C). See the full spec comparison and 30-year energy simulation above for a complete picture.
What is the efficiency of Aptos Solar DNA-120-BF26-365W and Aptos Solar DNA-120-BF10-450W?
Aptos Solar DNA-120-BF26-365 W has a module efficiency of 20.01%, while Aptos Solar DNA-120-BF10-450 W is 20.79%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does Aptos Solar DNA-120-BF26-365W use vs Aptos Solar DNA-120-BF10-450W?
Aptos Solar DNA-120-BF26-365 W uses PERC cells; Aptos Solar DNA-120-BF10-450 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-BF26-365W and Aptos Solar DNA-120-BF10-450W?
Aptos Solar DNA-120-BF26-365 W has a 30 years power warranty; Aptos Solar DNA-120-BF10-450 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-BF26-365W and Aptos Solar DNA-120-BF10-450W bifacial panels?
Both Aptos Solar DNA-120-BF26-365 W and Aptos Solar DNA-120-BF10-450 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.
