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 JKM525-54HL4M-BDV or Jinko Solar JKM425N-54HL4R-B?
According to our database: Jinko Solar JKM525-54HL4M-BDV has higher module efficiency (23.61% vs 21.27%). See the full spec comparison and 30-year energy simulation above for a complete picture.
What is the efficiency of Jinko Solar JKM525-54HL4M-BDV and Jinko Solar JKM425N-54HL4R-B?
Jinko Solar JKM525-54HL4M-BDV has a module efficiency of 23.61%, while Jinko Solar JKM425N-54HL4R-B is 21.27%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does Jinko Solar JKM525-54HL4M-BDV use vs Jinko Solar JKM425N-54HL4R-B?
Jinko Solar JKM525-54HL4M-BDV uses TOPCon cells; Jinko Solar JKM425N-54HL4R-B 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 JKM525-54HL4M-BDV and Jinko Solar JKM425N-54HL4R-B?
Jinko Solar JKM525-54HL4M-BDV has a 30 years power warranty; Jinko Solar JKM425N-54HL4R-B 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 JKM525-54HL4M-BDV and Jinko Solar JKM425N-54HL4R-B bifacial panels?
Jinko Solar JKM525-54HL4M-BDV is bifacial (captures light from both faces); Jinko Solar JKM425N-54HL4R-B is monofacial. Bifacial panels work best on ground mounts or raised structures with a light-coloured surface underneath.
