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 JKM485N-48QL6-DB-F2-EU or Jinko Solar JKM485N-48QL6-DB-F4-EU?
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 JKM485N-48QL6-DB-F2-EU and Jinko Solar JKM485N-48QL6-DB-F4-EU?
Jinko Solar JKM485N-48QL6-DB-F2-EU has a module efficiency of 24.27%, while Jinko Solar JKM485N-48QL6-DB-F4-EU is 24.27%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does Jinko Solar JKM485N-48QL6-DB-F2-EU use vs Jinko Solar JKM485N-48QL6-DB-F4-EU?
Jinko Solar JKM485N-48QL6-DB-F2-EU uses TOPCon cells; Jinko Solar JKM485N-48QL6-DB-F4-EU 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 JKM485N-48QL6-DB-F2-EU and Jinko Solar JKM485N-48QL6-DB-F4-EU?
Jinko Solar JKM485N-48QL6-DB-F2-EU has a 30 years power warranty; Jinko Solar JKM485N-48QL6-DB-F4-EU 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.
