Questions about this pairing

Which panel is better: Jinko Solar JKM455N-48HL4M-BDV-Z2-EU or Jinko Solar JKM555M-72HL4-BDVP?
According to our database: Jinko Solar JKM455N-48HL4M-BDV-Z2-EU has higher module efficiency (22.77% vs 21.48%); Jinko Solar JKM455N-48HL4M-BDV-Z2-EU tolerates heat better (temp coeff -0.290%/°C vs -0.350%/°C). See the full spec comparison and 30-year energy simulation above for a complete picture.
What is the efficiency of Jinko Solar JKM455N-48HL4M-BDV-Z2-EU and Jinko Solar JKM555M-72HL4-BDVP?
Jinko Solar JKM455N-48HL4M-BDV-Z2-EU has a module efficiency of 22.77%, while Jinko Solar JKM555M-72HL4-BDVP is 21.48%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does Jinko Solar JKM455N-48HL4M-BDV-Z2-EU use vs Jinko Solar JKM555M-72HL4-BDVP?
Jinko Solar JKM455N-48HL4M-BDV-Z2-EU uses TOPCon cells; Jinko Solar JKM555M-72HL4-BDVP uses PERC. 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 JKM455N-48HL4M-BDV-Z2-EU and Jinko Solar JKM555M-72HL4-BDVP?
Jinko Solar JKM455N-48HL4M-BDV-Z2-EU has a 30 years power warranty; Jinko Solar JKM555M-72HL4-BDVP 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 JKM455N-48HL4M-BDV-Z2-EU and Jinko Solar JKM555M-72HL4-BDVP bifacial panels?
Both Jinko Solar JKM455N-48HL4M-BDV-Z2-EU and Jinko Solar JKM555M-72HL4-BDVP 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.
