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 (-0.290 %/°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 HiS-T630NJ or Hyundai HiS-T635NJ?
According to our database: Hyundai HiS-T635NJ has higher module efficiency (22.72% vs 22.54%). See the full spec comparison and 30-year energy simulation above for a complete picture.
What is the efficiency of Hyundai HiS-T630NJ and Hyundai HiS-T635NJ?
Hyundai HiS-T630NJ has a module efficiency of 22.54%, while Hyundai HiS-T635NJ is 22.72%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does Hyundai HiS-T630NJ use vs Hyundai HiS-T635NJ?
Hyundai HiS-T630NJ uses TOPCon cells; Hyundai HiS-T635NJ 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 HiS-T630NJ and Hyundai HiS-T635NJ?
Hyundai HiS-T630NJ has a 30 years power warranty; Hyundai HiS-T635NJ 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 HiS-T630NJ and Hyundai HiS-T635NJ bifacial panels?
Both Hyundai HiS-T630NJ and Hyundai HiS-T635NJ 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.
