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: Trina Solar TSM-460NEG9R.28 or Trina Solar TSM-455NEG9R.28?
According to our database: Trina Solar TSM-460NEG9R.28 has higher module efficiency (23.00% vs 22.80%). See the full spec comparison and 30-year energy simulation above for a complete picture.
What is the efficiency of Trina Solar TSM-460NEG9R.28 and Trina Solar TSM-455NEG9R.28?
Trina Solar TSM-460NEG9R.28 has a module efficiency of 23.00%, while Trina Solar TSM-455NEG9R.28 is 22.80%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does Trina Solar TSM-460NEG9R.28 use vs Trina Solar TSM-455NEG9R.28?
Trina Solar TSM-460NEG9R.28 uses TOPCon cells; Trina Solar TSM-455NEG9R.28 uses TOPCon. 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-460NEG9R.28 and Trina Solar TSM-455NEG9R.28?
Trina Solar TSM-460NEG9R.28 has a 30 years power warranty; Trina Solar TSM-455NEG9R.28 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 Trina Solar TSM-460NEG9R.28 and Trina Solar TSM-455NEG9R.28 bifacial panels?
Both Trina Solar TSM-460NEG9R.28 and Trina Solar TSM-455NEG9R.28 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.
