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-565NT72-HLV or EGing PV EG-565NT72-HL/BF-DG?
According to our database: both panels are closely matched on key specs - the decision often comes down to price and local availability. See the full spec comparison and 30-year energy simulation above for a complete picture.
What is the efficiency of EGing PV EG-565NT72-HLV and EGing PV EG-565NT72-HL/BF-DG?
EGing PV EG-565NT72-HLV has a module efficiency of 21.87%, while EGing PV EG-565NT72-HL/BF-DG is 21.87%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does EGing PV EG-565NT72-HLV use vs EGing PV EG-565NT72-HL/BF-DG?
EGing PV EG-565NT72-HLV uses TOPCon cells; EGing PV EG-565NT72-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-565NT72-HLV and EGing PV EG-565NT72-HL/BF-DG?
EGing PV EG-565NT72-HLV has a 25 years power warranty; EGing PV EG-565NT72-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-565NT72-HLV and EGing PV EG-565NT72-HL/BF-DG bifacial panels?
EGing PV EG-565NT72-HL/BF-DG is bifacial (captures light from both faces); EGing PV EG-565NT72-HLV is monofacial. Bifacial panels work best on ground mounts or raised structures with a light-coloured surface underneath.
