Questions about this pairing
Which panel is better: AIKO AIKO-A700-MAE78Dw or Jetion JT755SLk(B)?
According to our database: AIKO AIKO-A700-MAE78Dw has higher module efficiency (25.00% vs 24.30%); Jetion JT755SLk(B) 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 AIKO AIKO-A700-MAE78Dw and Jetion JT755SLk(B)?
AIKO AIKO-A700-MAE78Dw has a module efficiency of 25.00%, while Jetion JT755SLk(B) is 24.30%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does AIKO AIKO-A700-MAE78Dw use vs Jetion JT755SLk(B)?
AIKO AIKO-A700-MAE78Dw uses Back Contact cells; Jetion JT755SLk(B) uses HJT. 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 AIKO AIKO-A700-MAE78Dw and Jetion JT755SLk(B)?
AIKO AIKO-A700-MAE78Dw has a 30 years power warranty; Jetion JT755SLk(B) 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 AIKO AIKO-A700-MAE78Dw and Jetion JT755SLk(B) bifacial panels?
Jetion JT755SLk(B) is bifacial (captures light from both faces); AIKO AIKO-A700-MAE78Dw is monofacial. Bifacial panels work best on ground mounts or raised structures with a light-coloured surface underneath.
