Jinko Solar JKM650-670N-66QL6-BDV (670W class) vs Jinko Solar JKM650-670N-66QL6-BDV-F2-EU (670W)
VS
The verdict
Identical on every published parameter
All 18 comparable parameters agree, with 1 more left out because at least one datasheet does not publish it. Two records this alike are usually one panel sold under two names, or two bins of the same production line - decide on price and on who you would rather buy from.

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 JKM650-670N-66QL6-BDV (670W class) or Jinko Solar JKM650-670N-66QL6-BDV-F2-EU (670W)?
According to our database: both panels are closely matched on key specs - the decision often comes down to price and local availability. See the full spec comparison and 30-year energy simulation above for a complete picture.
What is the efficiency of Jinko Solar JKM650-670N-66QL6-BDV (670W class) and Jinko Solar JKM650-670N-66QL6-BDV-F2-EU (670W)?
Jinko Solar JKM650-670N-66QL6-BDV (670 W class) has a module efficiency of 24.80%, while Jinko Solar JKM650-670N-66QL6-BDV-F2-EU (670 W) is 24.80%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does Jinko Solar JKM650-670N-66QL6-BDV (670W class) use vs Jinko Solar JKM650-670N-66QL6-BDV-F2-EU (670W)?
Jinko Solar JKM650-670N-66QL6-BDV (670 W class) uses TOPCon cells; Jinko Solar JKM650-670N-66QL6-BDV-F2-EU (670 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 JKM650-670N-66QL6-BDV (670W class) and Jinko Solar JKM650-670N-66QL6-BDV-F2-EU (670W)?
Jinko Solar JKM650-670N-66QL6-BDV (670 W class) has a 30 years power warranty; Jinko Solar JKM650-670N-66QL6-BDV-F2-EU (670 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 JKM650-670N-66QL6-BDV (670W class) and Jinko Solar JKM650-670N-66QL6-BDV-F2-EU (670W) bifacial panels?
Both Jinko Solar JKM650-670N-66QL6-BDV (670 W class) and Jinko Solar JKM650-670N-66QL6-BDV-F2-EU (670 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.
