Hanersun HN18N-54HT440W vs JA Solar JAM54D41-440/LB

Q: Which panel is better: Hanersun HN18N-54HT440W or JA Solar JAM54D41-440/LB?

According to our database: Hanersun HN18N-54HT440W has higher module efficiency (22.50% vs 22.00%); Hanersun HN18N-54HT440W 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.

Q: What is the efficiency of Hanersun HN18N-54HT440W and JA Solar JAM54D41-440/LB?

Hanersun HN18N-54HT440W has a module efficiency of 22.50%, while JA Solar JAM54D41-440/LB is 22.00%. Higher efficiency means more electricity from the same roof area - useful when space is limited.

Q: What cell technology does Hanersun HN18N-54HT440W use vs JA Solar JAM54D41-440/LB?

Hanersun HN18N-54HT440W uses TOPCon cells; JA Solar JAM54D41-440/LB uses TOPCon. Modern n-type technologies (TOPCon, HJT, BC) typically deliver higher efficiency and lower degradation compared to older PERC (p-type) cells.

Q: What is the warranty on Hanersun HN18N-54HT440W and JA Solar JAM54D41-440/LB?

Hanersun HN18N-54HT440W has a 30 years power warranty; JA Solar JAM54D41-440/LB 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.

Q: Are Hanersun HN18N-54HT440W and JA Solar JAM54D41-440/LB bifacial panels?

Both Hanersun HN18N-54HT440W and JA Solar JAM54D41-440/LB 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.
