Questions about this pairing
Which panel is better: Hanersun HN21N-66HT750W or Hanersun HN21RN-66QT655W?
According to our database: Hanersun HN21RN-66QT655 W has higher module efficiency (24.20% vs 24.10%); Hanersun HN21RN-66QT655 W tolerates heat better (temp coeff -0.260%/°C vs -0.280%/°C). See the full spec comparison and 30-year energy simulation above for a complete picture.
What is the efficiency of Hanersun HN21N-66HT750W and Hanersun HN21RN-66QT655W?
Hanersun HN21N-66HT750 W has a module efficiency of 24.10%, while Hanersun HN21RN-66QT655 W is 24.20%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does Hanersun HN21N-66HT750W use vs Hanersun HN21RN-66QT655W?
Hanersun HN21N-66HT750 W uses TOPCon cells; Hanersun HN21RN-66QT655 W 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 Hanersun HN21N-66HT750W and Hanersun HN21RN-66QT655W?
Hanersun HN21N-66HT750 W has a 30 years power warranty; Hanersun HN21RN-66QT655 W 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 Hanersun HN21N-66HT750W and Hanersun HN21RN-66QT655W bifacial panels?
Both Hanersun HN21N-66HT750 W and Hanersun HN21RN-66QT655 W 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.
