Questions about this pairing

Which panel is better: Trina Solar TSM-NE21 700W or Trina Solar TSM-NEG21C.20Q-760?
According to our database: Trina Solar TSM-NEG21C.20Q-760 has higher module efficiency (24.50% vs 22.50%); Trina Solar TSM-NEG21C.20Q-760 tolerates heat better (temp coeff -0.260%/°C vs -0.290%/°C). See the full spec comparison and 30-year energy simulation above for a complete picture.
What is the efficiency of Trina Solar TSM-NE21 700W and Trina Solar TSM-NEG21C.20Q-760?
Trina Solar TSM-NE21 700 W has a module efficiency of 22.50%, while Trina Solar TSM-NEG21C.20Q-760 is 24.50%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does Trina Solar TSM-NE21 700W use vs Trina Solar TSM-NEG21C.20Q-760?
Trina Solar TSM-NE21 700 W uses TOPCon cells; Trina Solar TSM-NEG21C.20Q-760 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-NE21 700W and Trina Solar TSM-NEG21C.20Q-760?
Trina Solar TSM-NE21 700 W has a 25 years power warranty; Trina Solar TSM-NEG21C.20Q-760 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-NE21 700W and Trina Solar TSM-NEG21C.20Q-760 bifacial panels?
Trina Solar TSM-NEG21C.20Q-760 is bifacial (captures light from both faces); Trina Solar TSM-NE21 700 W is monofacial. Bifacial panels work best on ground mounts or raised structures with a light-coloured surface underneath.
