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 (-0.340 %/°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: Trina Solar TSM-DE19-550 or Trina Solar TSM-DE19R-565?
According to our database: Trina Solar TSM-DE19-550 has higher module efficiency (21.00% vs 20.90%). See the full spec comparison and 30-year energy simulation above for a complete picture.
What is the efficiency of Trina Solar TSM-DE19-550 and Trina Solar TSM-DE19R-565?
Trina Solar TSM-DE19-550 has a module efficiency of 21.00%, while Trina Solar TSM-DE19R-565 is 20.90%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does Trina Solar TSM-DE19-550 use vs Trina Solar TSM-DE19R-565?
Trina Solar TSM-DE19-550 uses PERC cells; Trina Solar TSM-DE19R-565 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 Trina Solar TSM-DE19-550 and Trina Solar TSM-DE19R-565?
Trina Solar TSM-DE19-550 has a 25 years power warranty; Trina Solar TSM-DE19R-565 has a 25 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.
