Questions about this pairing
Which panel is better: Hyundai HiT-H455CE-BF or JA Solar JAM54D40-470/LR?
According to our database: JA Solar JAM54D40-470/LR has higher module efficiency (23.50% vs 22.80%); Hyundai HiT-H455CE-BF tolerates heat better (temp coeff -0.240%/°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 Hyundai HiT-H455CE-BF and JA Solar JAM54D40-470/LR?
Hyundai HiT-H455CE-BF has a module efficiency of 22.80%, while JA Solar JAM54D40-470/LR is 23.50%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does Hyundai HiT-H455CE-BF use vs JA Solar JAM54D40-470/LR?
Hyundai HiT-H455CE-BF uses HJT cells; JA Solar JAM54D40-470/LR uses N-type. 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 Hyundai HiT-H455CE-BF and JA Solar JAM54D40-470/LR?
Hyundai HiT-H455CE-BF has a 30 years power warranty; JA Solar JAM54D40-470/LR 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 Hyundai HiT-H455CE-BF and JA Solar JAM54D40-470/LR bifacial panels?
Hyundai HiT-H455CE-BF is bifacial (captures light from both faces); JA Solar JAM54D40-470/LR is monofacial. Bifacial panels work best on ground mounts or raised structures with a light-coloured surface underneath.
