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 JKM425N-54HL4R-B or Jinko Solar JKM500-54HL4M-BDV?
According to our database: Jinko Solar JKM500-54HL4M-BDV has higher module efficiency (22.48% 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 JKM425N-54HL4R-B and Jinko Solar JKM500-54HL4M-BDV?
Jinko Solar JKM425N-54HL4R-B has a module efficiency of 21.27%, while Jinko Solar JKM500-54HL4M-BDV is 22.48%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does Jinko Solar JKM425N-54HL4R-B use vs Jinko Solar JKM500-54HL4M-BDV?
Jinko Solar JKM425N-54HL4R-B uses N-type cells; Jinko Solar JKM500-54HL4M-BDV 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 Jinko Solar JKM425N-54HL4R-B and Jinko Solar JKM500-54HL4M-BDV?
Jinko Solar JKM425N-54HL4R-B has a 30 years power warranty; Jinko Solar JKM500-54HL4M-BDV 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 JKM425N-54HL4R-B and Jinko Solar JKM500-54HL4M-BDV bifacial panels?
Jinko Solar JKM500-54HL4M-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.
