What it means on a roof
Thirty years of production
A 1.0% first-year loss then 0.40% a year, assumed for both panels, at 1,200 kWh/kWp a year
Same temp coeff. for both panels (-0.300 %/°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 JKM605N-78HL4-BDV or Jinko Solar JKM565N-72HL4-BDV?
According to our database: Jinko Solar JKM565N-72HL4-BDV has higher module efficiency (21.87% vs 21.64%). See the full spec comparison and 30-year energy simulation above for a complete picture.
What is the efficiency of Jinko Solar JKM605N-78HL4-BDV and Jinko Solar JKM565N-72HL4-BDV?
Jinko Solar JKM605N-78HL4-BDV has a module efficiency of 21.64%, while Jinko Solar JKM565N-72HL4-BDV is 21.87%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does Jinko Solar JKM605N-78HL4-BDV use vs Jinko Solar JKM565N-72HL4-BDV?
Jinko Solar JKM605N-78HL4-BDV uses N-type cells; Jinko Solar JKM565N-72HL4-BDV 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 JKM605N-78HL4-BDV and Jinko Solar JKM565N-72HL4-BDV?
Jinko Solar JKM605N-78HL4-BDV has a 30 years power warranty; Jinko Solar JKM565N-72HL4-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 JKM605N-78HL4-BDV and Jinko Solar JKM565N-72HL4-BDV bifacial panels?
Both Jinko Solar JKM605N-78HL4-BDV and Jinko Solar JKM565N-72HL4-BDV 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.
