Questions about this pairing
Which panel is better: Jinko Solar JKM585N-72HL4-BDV or Jinko Solar JKM580N-72HL4-BDV?
According to our database: Jinko Solar JKM585N-72HL4-BDV has higher module efficiency (22.65% vs 22.45%); Jinko Solar JKM585N-72HL4-BDV tolerates heat better (temp coeff -0.290%/°C vs -0.300%/°C). See the full spec comparison and 30-year energy simulation above for a complete picture.
What is the efficiency of Jinko Solar JKM585N-72HL4-BDV and Jinko Solar JKM580N-72HL4-BDV?
Jinko Solar JKM585N-72HL4-BDV has a module efficiency of 22.65%, while Jinko Solar JKM580N-72HL4-BDV is 22.45%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does Jinko Solar JKM585N-72HL4-BDV use vs Jinko Solar JKM580N-72HL4-BDV?
Jinko Solar JKM585N-72HL4-BDV uses N-type cells; Jinko Solar JKM580N-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 JKM585N-72HL4-BDV and Jinko Solar JKM580N-72HL4-BDV?
Jinko Solar JKM585N-72HL4-BDV has a 30 years power warranty; Jinko Solar JKM580N-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 JKM585N-72HL4-BDV and Jinko Solar JKM580N-72HL4-BDV bifacial panels?
Both Jinko Solar JKM585N-72HL4-BDV and Jinko Solar JKM580N-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.
