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 (-0.240 %/°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 HiT-H520LF-FB(ZB) or Hyundai HiT-H515LF-FB(ZB)?
According to our database: Hyundai HiT-H520LF-FB(ZB) has higher module efficiency (23.40% vs 23.20%). See the full spec comparison and 30-year energy simulation above for a complete picture.
What is the efficiency of Hyundai HiT-H520LF-FB(ZB) and Hyundai HiT-H515LF-FB(ZB)?
Hyundai HiT-H520LF-FB(ZB) has a module efficiency of 23.40%, while Hyundai HiT-H515LF-FB(ZB) is 23.20%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does Hyundai HiT-H520LF-FB(ZB) use vs Hyundai HiT-H515LF-FB(ZB)?
Hyundai HiT-H520LF-FB(ZB) uses HJT cells; Hyundai HiT-H515LF-FB(ZB) uses HJT. 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 HiT-H520LF-FB(ZB) and Hyundai HiT-H515LF-FB(ZB)?
Hyundai HiT-H520LF-FB(ZB) has a 30 years power warranty; Hyundai HiT-H515LF-FB(ZB) 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 HiT-H520LF-FB(ZB) and Hyundai HiT-H515LF-FB(ZB) bifacial panels?
Both Hyundai HiT-H520LF-FB(ZB) and Hyundai HiT-H515LF-FB(ZB) 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.
