Questions about this pairing
Which panel is better: Hanersun HN18-72H585W or Hanersun HN18N-54HT440W?
According to our database: Hanersun HN18-72H585 W has higher module efficiency (22.65% vs 22.50%); Hanersun HN18N-54HT440 W tolerates heat better (temp coeff -0.280%/°C vs -0.310%/°C). See the full spec comparison and 30-year energy simulation above for a complete picture.
What is the efficiency of Hanersun HN18-72H585W and Hanersun HN18N-54HT440W?
Hanersun HN18-72H585 W has a module efficiency of 22.65%, while Hanersun HN18N-54HT440 W is 22.50%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does Hanersun HN18-72H585W use vs Hanersun HN18N-54HT440W?
Hanersun HN18-72H585 W uses TOPCon cells; Hanersun HN18N-54HT440 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 HN18-72H585W and Hanersun HN18N-54HT440W?
Hanersun HN18-72H585 W has a 25 years power warranty; Hanersun HN18N-54HT440 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 HN18-72H585W and Hanersun HN18N-54HT440W bifacial panels?
Hanersun HN18N-54HT440 W is bifacial (captures light from both faces); Hanersun HN18-72H585 W is monofacial. Bifacial panels work best on ground mounts or raised structures with a light-coloured surface underneath.
