Questions about this pairing
Which panel is better: Aptos Solar DNA-144-MF26-450W or Aptos Solar DNA-144-BF10-545W-DG?
According to our database: Aptos Solar DNA-144-BF10-545 W-DG has higher module efficiency (21.09% vs 20.21%); Aptos Solar DNA-144-BF10-545 W-DG tolerates heat better (temp coeff -0.335%/°C vs -0.380%/°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-MF26-450W and Aptos Solar DNA-144-BF10-545W-DG?
Aptos Solar DNA-144-MF26-450 W has a module efficiency of 20.21%, while Aptos Solar DNA-144-BF10-545 W-DG is 21.09%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does Aptos Solar DNA-144-MF26-450W use vs Aptos Solar DNA-144-BF10-545W-DG?
Aptos Solar DNA-144-MF26-450 W uses PERC cells; Aptos Solar DNA-144-BF10-545 W-DG 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-MF26-450W and Aptos Solar DNA-144-BF10-545W-DG?
Aptos Solar DNA-144-MF26-450 W has a 30 years power warranty; Aptos Solar DNA-144-BF10-545 W-DG 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-MF26-450W and Aptos Solar DNA-144-BF10-545W-DG bifacial panels?
Aptos Solar DNA-144-BF10-545 W-DG is bifacial (captures light from both faces); Aptos Solar DNA-144-MF26-450 W is monofacial. Bifacial panels work best on ground mounts or raised structures with a light-coloured surface underneath.
