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 JKM655N-66QL6-BDV-AntiGlare-F1-EU or Jinko Solar JKM645-670N-66QL6-BDV-L?
According to our database: Jinko Solar JKM645-670N-66QL6-BDV-L has higher module efficiency (24.80% vs 24.25%). See the full spec comparison and 30-year energy simulation above for a complete picture.
What is the efficiency of Jinko Solar JKM655N-66QL6-BDV-AntiGlare-F1-EU and Jinko Solar JKM645-670N-66QL6-BDV-L?
Jinko Solar JKM655N-66QL6-BDV-AntiGlare-F1-EU has a module efficiency of 24.25%, while Jinko Solar JKM645-670N-66QL6-BDV-L is 24.80%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does Jinko Solar JKM655N-66QL6-BDV-AntiGlare-F1-EU use vs Jinko Solar JKM645-670N-66QL6-BDV-L?
Jinko Solar JKM655N-66QL6-BDV-AntiGlare-F1-EU uses N-type cells; Jinko Solar JKM645-670N-66QL6-BDV-L 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 JKM655N-66QL6-BDV-AntiGlare-F1-EU and Jinko Solar JKM645-670N-66QL6-BDV-L?
Jinko Solar JKM655N-66QL6-BDV-AntiGlare-F1-EU has a 30 years power warranty; Jinko Solar JKM645-670N-66QL6-BDV-L 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 JKM655N-66QL6-BDV-AntiGlare-F1-EU and Jinko Solar JKM645-670N-66QL6-BDV-L bifacial panels?
Both Jinko Solar JKM655N-66QL6-BDV-AntiGlare-F1-EU and Jinko Solar JKM645-670N-66QL6-BDV-L 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.
