Questions about this pairing
Which panel is better: JA Solar JAM54D41-440/LB or Hanersun HN18N-54HT440W?
According to our database: Hanersun HN18N-54HT440 W has higher module efficiency (22.50% vs 22.00%); Hanersun HN18N-54HT440 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 JA Solar JAM54D41-440/LB and Hanersun HN18N-54HT440W?
JA Solar JAM54D41-440/LB has a module efficiency of 22.00%, 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 JA Solar JAM54D41-440/LB use vs Hanersun HN18N-54HT440W?
JA Solar JAM54D41-440/LB 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 JA Solar JAM54D41-440/LB and Hanersun HN18N-54HT440W?
JA Solar JAM54D41-440/LB has a 30 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 JA Solar JAM54D41-440/LB and Hanersun HN18N-54HT440W bifacial panels?
Both JA Solar JAM54D41-440/LB and Hanersun HN18N-54HT440 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.
