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 (-0.290 %/°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 JKM430-455N-54HL4R-B-F8-EN (445W) or Jinko Solar JKM430-455N-54HL4R-B-F8-EN (450W bin)?
According to our database: Jinko Solar JKM430-455N-54HL4R-B-F8-EN (450 W bin) has higher module efficiency (22.52% vs 22.27%). See the full spec comparison and 30-year energy simulation above for a complete picture.
What is the efficiency of Jinko Solar JKM430-455N-54HL4R-B-F8-EN (445W) and Jinko Solar JKM430-455N-54HL4R-B-F8-EN (450W bin)?
Jinko Solar JKM430-455N-54HL4R-B-F8-EN (445 W) has a module efficiency of 22.27%, while Jinko Solar JKM430-455N-54HL4R-B-F8-EN (450 W bin) is 22.52%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does Jinko Solar JKM430-455N-54HL4R-B-F8-EN (445W) use vs Jinko Solar JKM430-455N-54HL4R-B-F8-EN (450W bin)?
Jinko Solar JKM430-455N-54HL4R-B-F8-EN (445 W) uses TOPCon cells; Jinko Solar JKM430-455N-54HL4R-B-F8-EN (450 W bin) 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 JKM430-455N-54HL4R-B-F8-EN (445W) and Jinko Solar JKM430-455N-54HL4R-B-F8-EN (450W bin)?
Jinko Solar JKM430-455N-54HL4R-B-F8-EN (445 W) has a 30 years power warranty; Jinko Solar JKM430-455N-54HL4R-B-F8-EN (450 W bin) 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.
