Questions about this pairing

Which panel is better: Silfab SIL-440 QD or Hyundai HiN-T440NF(BK)?
According to our database: Silfab SIL-440 QD has higher module efficiency (22.60% vs 22.53%); Silfab SIL-440 QD tolerates heat better (temp coeff -0.290%/°C vs -0.300%/°C). See the full spec comparison and 30-year energy simulation above for a complete picture.
What is the efficiency of Silfab SIL-440 QD and Hyundai HiN-T440NF(BK)?
Silfab SIL-440 QD has a module efficiency of 22.60%, while Hyundai HiN-T440NF(BK) is 22.53%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does Silfab SIL-440 QD use vs Hyundai HiN-T440NF(BK)?
Silfab SIL-440 QD uses N-type cells; Hyundai HiN-T440NF(BK) uses TOPCon. 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 Silfab SIL-440 QD and Hyundai HiN-T440NF(BK)?
Silfab SIL-440 QD has a 30 years power warranty; Hyundai HiN-T440NF(BK) 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 Silfab SIL-440 QD and Hyundai HiN-T440NF(BK) bifacial panels?
Hyundai HiN-T440NF(BK) is bifacial (captures light from both faces); Silfab SIL-440 QD is monofacial. Bifacial panels work best on ground mounts or raised structures with a light-coloured surface underneath.
