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 (-0.290 %/°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 JKM625-650N-78HL4-BDV or Jinko Solar JKM575-600N-72HL4-BDV (580W)?
According to our database: Jinko Solar JKM625-650N-78HL4-BDV has higher module efficiency (23.25% vs 22.45%). See the full spec comparison and 30-year energy simulation above for a complete picture.
What is the efficiency of Jinko Solar JKM625-650N-78HL4-BDV and Jinko Solar JKM575-600N-72HL4-BDV (580W)?
Jinko Solar JKM625-650N-78HL4-BDV has a module efficiency of 23.25%, while Jinko Solar JKM575-600N-72HL4-BDV (580 W) is 22.45%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does Jinko Solar JKM625-650N-78HL4-BDV use vs Jinko Solar JKM575-600N-72HL4-BDV (580W)?
Jinko Solar JKM625-650N-78HL4-BDV uses TOPCon cells; Jinko Solar JKM575-600N-72HL4-BDV (580 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 JKM625-650N-78HL4-BDV and Jinko Solar JKM575-600N-72HL4-BDV (580W)?
Jinko Solar JKM625-650N-78HL4-BDV has a 30 years power warranty; Jinko Solar JKM575-600N-72HL4-BDV (580 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 JKM625-650N-78HL4-BDV and Jinko Solar JKM575-600N-72HL4-BDV (580W) bifacial panels?
Both Jinko Solar JKM625-650N-78HL4-BDV and Jinko Solar JKM575-600N-72HL4-BDV (580 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.
