What it means on a roof

Thirty years of production
Each panel's own declared degradation curve, at 1,200 kWh/kWp a year
Same temp coeff. for both panels (-0.300 %/°C), so a warmer roof scales both curves by the same factor: the totals fall together and neither panel gains on the other.

Questions about this pairing

Which panel is better: Hyundai HiN-T435NF(BK) or Hyundai HiN-T440NF(BK)?
According to our database: Hyundai HiN-T440NF(BK) has higher module efficiency (22.53% vs 22.28%). See the full spec comparison and 30-year energy simulation above for a complete picture.
What is the efficiency of Hyundai HiN-T435NF(BK) and Hyundai HiN-T440NF(BK)?
Hyundai HiN-T435NF(BK) has a module efficiency of 22.28%, 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 Hyundai HiN-T435NF(BK) use vs Hyundai HiN-T440NF(BK)?
Hyundai HiN-T435NF(BK) uses TOPCon 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 Hyundai HiN-T435NF(BK) and Hyundai HiN-T440NF(BK)?
Hyundai HiN-T435NF(BK) 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 Hyundai HiN-T435NF(BK) and Hyundai HiN-T440NF(BK) bifacial panels?
Both Hyundai HiN-T435NF(BK) and Hyundai HiN-T440NF(BK) 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.
