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: JA Solar JAM54D41-440/LR or Jinko Solar JKM470N-48HL4M-BDV-Z2-EU?
According to our database: Jinko Solar JKM470N-48HL4M-BDV-Z2-EU has higher module efficiency (23.52% vs 22.00%). See the full spec comparison and 30-year energy simulation above for a complete picture.
What is the efficiency of JA Solar JAM54D41-440/LR and Jinko Solar JKM470N-48HL4M-BDV-Z2-EU?
JA Solar JAM54D41-440/LR has a module efficiency of 22.00%, while Jinko Solar JKM470N-48HL4M-BDV-Z2-EU is 23.52%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does JA Solar JAM54D41-440/LR use vs Jinko Solar JKM470N-48HL4M-BDV-Z2-EU?
JA Solar JAM54D41-440/LR uses TOPCon cells; Jinko Solar JKM470N-48HL4M-BDV-Z2-EU 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 JA Solar JAM54D41-440/LR and Jinko Solar JKM470N-48HL4M-BDV-Z2-EU?
JA Solar JAM54D41-440/LR has a 30 years power warranty; Jinko Solar JKM470N-48HL4M-BDV-Z2-EU 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 JA Solar JAM54D41-440/LR and Jinko Solar JKM470N-48HL4M-BDV-Z2-EU bifacial panels?
Jinko Solar JKM470N-48HL4M-BDV-Z2-EU is bifacial (captures light from both faces); JA Solar JAM54D41-440/LR is monofacial. Bifacial panels work best on ground mounts or raised structures with a light-coloured surface underneath.
