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 (-0.260 %/°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 JKM495-520N-51QL6-BDV-F2-EU (520W) or Jinko Solar JKM495-520N-51QL6-BDV-F2-EU (500W)?
According to our database: Jinko Solar JKM495-520N-51QL6-BDV-F2-EU (520 W) has higher module efficiency (24.06% vs 23.13%). See the full spec comparison and 30-year energy simulation above for a complete picture.
What is the efficiency of Jinko Solar JKM495-520N-51QL6-BDV-F2-EU (520W) and Jinko Solar JKM495-520N-51QL6-BDV-F2-EU (500W)?
Jinko Solar JKM495-520N-51QL6-BDV-F2-EU (520 W) has a module efficiency of 24.06%, while Jinko Solar JKM495-520N-51QL6-BDV-F2-EU (500 W) is 23.13%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does Jinko Solar JKM495-520N-51QL6-BDV-F2-EU (520W) use vs Jinko Solar JKM495-520N-51QL6-BDV-F2-EU (500W)?
Jinko Solar JKM495-520N-51QL6-BDV-F2-EU (520 W) uses TOPCon cells; Jinko Solar JKM495-520N-51QL6-BDV-F2-EU (500 W) 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 JKM495-520N-51QL6-BDV-F2-EU (520W) and Jinko Solar JKM495-520N-51QL6-BDV-F2-EU (500W)?
Jinko Solar JKM495-520N-51QL6-BDV-F2-EU (520 W) has a 30 years power warranty; Jinko Solar JKM495-520N-51QL6-BDV-F2-EU (500 W) 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 JKM495-520N-51QL6-BDV-F2-EU (520W) and Jinko Solar JKM495-520N-51QL6-BDV-F2-EU (500W) bifacial panels?
Both Jinko Solar JKM495-520N-51QL6-BDV-F2-EU (520 W) and Jinko Solar JKM495-520N-51QL6-BDV-F2-EU (500 W) are bifacial - they capture reflected light from the ground, which can add 5-15% more annual energy on ground-mount or elevated rooftop installations with a light surface beneath.
