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 (-0.350 %/°C), so a warmer roof scales both curves by the same factor: the totals fall together and neither panel gains on the other.

Which panel is better: Jinko Solar JKM550M-72HL4-BDVP or Jinko Solar JKM545M-72HL4-BDVP?
According to our database: Jinko Solar JKM550M-72HL4-BDVP has higher module efficiency (21.29% vs 21.13%). See the full spec comparison and 30-year energy simulation above for a complete picture.
What is the efficiency of Jinko Solar JKM550M-72HL4-BDVP and Jinko Solar JKM545M-72HL4-BDVP?
Jinko Solar JKM550M-72HL4-BDVP has a module efficiency of 21.29%, while Jinko Solar JKM545M-72HL4-BDVP is 21.13%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does Jinko Solar JKM550M-72HL4-BDVP use vs Jinko Solar JKM545M-72HL4-BDVP?
Jinko Solar JKM550M-72HL4-BDVP uses PERC cells; Jinko Solar JKM545M-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 JKM550M-72HL4-BDVP and Jinko Solar JKM545M-72HL4-BDVP?
Jinko Solar JKM550M-72HL4-BDVP has a 30 years power warranty; Jinko Solar JKM545M-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 JKM550M-72HL4-BDVP and Jinko Solar JKM545M-72HL4-BDVP bifacial panels?
Both Jinko Solar JKM550M-72HL4-BDVP and Jinko Solar JKM545M-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.
