Trina Solar TSM-NE21 700W vs Trina Solar TSM-NE21 725W

Q: Which panel is better: Trina Solar TSM-NE21 700W or Trina Solar TSM-NE21 725W?

According to our database: Trina Solar TSM-NE21 725W has higher module efficiency (23.30% vs 22.50%). See the full spec comparison and 30-year energy simulation above for a complete picture.

Q: What is the efficiency of Trina Solar TSM-NE21 700W and Trina Solar TSM-NE21 725W?

Trina Solar TSM-NE21 700W has a module efficiency of 22.50%, while Trina Solar TSM-NE21 725W is 23.30%. Higher efficiency means more electricity from the same roof area - useful when space is limited.

Q: What cell technology does Trina Solar TSM-NE21 700W use vs Trina Solar TSM-NE21 725W?

Trina Solar TSM-NE21 700W uses TOPCon cells; Trina Solar TSM-NE21 725W uses TOPCon. Modern n-type technologies (TOPCon, HJT, BC) typically deliver higher efficiency and lower degradation compared to older PERC (p-type) cells.

Q: What is the warranty on Trina Solar TSM-NE21 700W and Trina Solar TSM-NE21 725W?

Trina Solar TSM-NE21 700W has a 25 years power warranty; Trina Solar TSM-NE21 725W 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.

What it means on a roof

Thirty years of production

Each panel's own declared degradation curve, at 1,200 kWh/kWp a year

Cell temperature

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.
