Questions about this pairing
Which panel is better: Aptos Solar DNA-120-MF10-460W or Aptos Solar DNA-144-MF26-445W?
According to our database: Aptos Solar DNA-120-MF10-460 W has higher module efficiency (21.26% vs 19.98%); Aptos Solar DNA-120-MF10-460 W tolerates heat better (temp coeff -0.350%/°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-120-MF10-460W and Aptos Solar DNA-144-MF26-445W?
Aptos Solar DNA-120-MF10-460 W has a module efficiency of 21.26%, while Aptos Solar DNA-144-MF26-445 W is 19.98%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does Aptos Solar DNA-120-MF10-460W use vs Aptos Solar DNA-144-MF26-445W?
Aptos Solar DNA-120-MF10-460 W uses PERC cells; Aptos Solar DNA-144-MF26-445 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-MF10-460W and Aptos Solar DNA-144-MF26-445W?
Aptos Solar DNA-120-MF10-460 W has a 30 years power warranty; Aptos Solar DNA-144-MF26-445 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.
