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: EGing PV EG-580NT72-HL/BF-DG or EGing PV EG-575NT72-HL/BF-DG?
According to our database: EGing PV EG-580NT72-HL/BF-DG has higher module efficiency (22.45% vs 22.25%). See the full spec comparison and 30-year energy simulation above for a complete picture.
What is the efficiency of EGing PV EG-580NT72-HL/BF-DG and EGing PV EG-575NT72-HL/BF-DG?
EGing PV EG-580NT72-HL/BF-DG has a module efficiency of 22.45%, while EGing PV EG-575NT72-HL/BF-DG is 22.25%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does EGing PV EG-580NT72-HL/BF-DG use vs EGing PV EG-575NT72-HL/BF-DG?
EGing PV EG-580NT72-HL/BF-DG uses TOPCon cells; EGing PV EG-575NT72-HL/BF-DG 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 EGing PV EG-580NT72-HL/BF-DG and EGing PV EG-575NT72-HL/BF-DG?
EGing PV EG-580NT72-HL/BF-DG has a 30 years power warranty; EGing PV EG-575NT72-HL/BF-DG 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 EGing PV EG-580NT72-HL/BF-DG and EGing PV EG-575NT72-HL/BF-DG bifacial panels?
Both EGing PV EG-580NT72-HL/BF-DG and EGing PV EG-575NT72-HL/BF-DG 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.
