Questions about this pairing

Which panel is better: TCL Zhonghuan HSM-ND54-GR500 or Hanersun HN21RN-54HT500W?
According to our database: Hanersun HN21RN-54HT500 W tolerates heat better (temp coeff -0.280%/°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 TCL Zhonghuan HSM-ND54-GR500 and Hanersun HN21RN-54HT500W?
TCL Zhonghuan HSM-ND54-GR500 has a module efficiency of 22.50%, while Hanersun HN21RN-54HT500 W is 22.50%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does TCL Zhonghuan HSM-ND54-GR500 use vs Hanersun HN21RN-54HT500W?
TCL Zhonghuan HSM-ND54-GR500 uses TOPCon cells; Hanersun HN21RN-54HT500 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 TCL Zhonghuan HSM-ND54-GR500 and Hanersun HN21RN-54HT500W?
TCL Zhonghuan HSM-ND54-GR500 has a 30 years power warranty; Hanersun HN21RN-54HT500 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 TCL Zhonghuan HSM-ND54-GR500 and Hanersun HN21RN-54HT500W bifacial panels?
Both TCL Zhonghuan HSM-ND54-GR500 and Hanersun HN21RN-54HT500 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.
