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: Jinko Solar JKM465N-48HL4M-BDV-Z2-EU or JA Solar JAM54D40-460/LR?
According to our database: Jinko Solar JKM465N-48HL4M-BDV-Z2-EU has higher module efficiency (23.27% vs 23.00%). See the full spec comparison and 30-year energy simulation above for a complete picture.
What is the efficiency of Jinko Solar JKM465N-48HL4M-BDV-Z2-EU and JA Solar JAM54D40-460/LR?
Jinko Solar JKM465N-48HL4M-BDV-Z2-EU has a module efficiency of 23.27%, while JA Solar JAM54D40-460/LR is 23.00%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does Jinko Solar JKM465N-48HL4M-BDV-Z2-EU use vs JA Solar JAM54D40-460/LR?
Jinko Solar JKM465N-48HL4M-BDV-Z2-EU uses TOPCon cells; JA Solar JAM54D40-460/LR uses N-type. 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 Jinko Solar JKM465N-48HL4M-BDV-Z2-EU and JA Solar JAM54D40-460/LR?
Jinko Solar JKM465N-48HL4M-BDV-Z2-EU has a 30 years power warranty; JA Solar JAM54D40-460/LR 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 Jinko Solar JKM465N-48HL4M-BDV-Z2-EU and JA Solar JAM54D40-460/LR bifacial panels?
Jinko Solar JKM465N-48HL4M-BDV-Z2-EU is bifacial (captures light from both faces); JA Solar JAM54D40-460/LR is monofacial. Bifacial panels work best on ground mounts or raised structures with a light-coloured surface underneath.
