Aptos Solar DNA-144-BF10-540W-DG vs Waaree Bi-55-540

Q: Which panel is better: Aptos Solar DNA-144-BF10-540W-DG or Waaree Bi-55-540?

According to our database: Waaree Bi-55-540 has higher module efficiency (20.98% vs 20.90%); Aptos Solar DNA-144-BF10-540W-DG tolerates heat better (temp coeff -0.335%/°C vs -0.350%/°C). See the full spec comparison and 30-year energy simulation above for a complete picture.

Q: What is the efficiency of Aptos Solar DNA-144-BF10-540W-DG and Waaree Bi-55-540?

Aptos Solar DNA-144-BF10-540W-DG has a module efficiency of 20.90%, while Waaree Bi-55-540 is 20.98%. Higher efficiency means more electricity from the same roof area - useful when space is limited.

Q: What cell technology does Aptos Solar DNA-144-BF10-540W-DG use vs Waaree Bi-55-540?

Aptos Solar DNA-144-BF10-540W-DG uses PERC cells; Waaree Bi-55-540 uses PERC. Modern n-type technologies (TOPCon, HJT, BC) typically deliver higher efficiency and lower degradation compared to older PERC (p-type) cells.

Q: What is the warranty on Aptos Solar DNA-144-BF10-540W-DG and Waaree Bi-55-540?

Aptos Solar DNA-144-BF10-540W-DG has a 30 years power warranty; Waaree Bi-55-540 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.

Q: Are Aptos Solar DNA-144-BF10-540W-DG and Waaree Bi-55-540 bifacial panels?

Both Aptos Solar DNA-144-BF10-540W-DG and Waaree Bi-55-540 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.
