Questions about this pairing
Which panel is better: Longi Solar LR7-54HJD-505M or AIKO AIKO-A485-MCE54Db?
According to our database: Longi Solar LR7-54HJD-505M has higher module efficiency (24.70% vs 24.30%); Longi Solar LR7-54HJD-505M tolerates heat better (temp coeff -0.240%/°C vs -0.260%/°C). See the full spec comparison and 30-year energy simulation above for a complete picture.
What is the efficiency of Longi Solar LR7-54HJD-505M and AIKO AIKO-A485-MCE54Db?
Longi Solar LR7-54HJD-505M has a module efficiency of 24.70%, while AIKO AIKO-A485-MCE54Db is 24.30%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does Longi Solar LR7-54HJD-505M use vs AIKO AIKO-A485-MCE54Db?
Longi Solar LR7-54HJD-505M uses Back Contact cells; AIKO AIKO-A485-MCE54Db uses Back Contact. 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 Longi Solar LR7-54HJD-505M and AIKO AIKO-A485-MCE54Db?
Longi Solar LR7-54HJD-505M has a 30 years power warranty; AIKO AIKO-A485-MCE54Db 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 Longi Solar LR7-54HJD-505M and AIKO AIKO-A485-MCE54Db bifacial panels?
Longi Solar LR7-54HJD-505M is bifacial (captures light from both faces); AIKO AIKO-A485-MCE54Db is monofacial. Bifacial panels work best on ground mounts or raised structures with a light-coloured surface underneath.
