Questions about this pairing
Which panel is better: AIKO AIKO-A655-MDE72Mw or Jinko Solar JKM640N-66HL4M-BDV?
According to our database: AIKO AIKO-A655-MDE72Mw has higher module efficiency (24.20% vs 23.69%); AIKO AIKO-A655-MDE72Mw tolerates heat better (temp coeff -0.260%/°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 AIKO AIKO-A655-MDE72Mw and Jinko Solar JKM640N-66HL4M-BDV?
AIKO AIKO-A655-MDE72Mw has a module efficiency of 24.20%, while Jinko Solar JKM640N-66HL4M-BDV is 23.69%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does AIKO AIKO-A655-MDE72Mw use vs Jinko Solar JKM640N-66HL4M-BDV?
AIKO AIKO-A655-MDE72Mw uses Back Contact cells; Jinko Solar JKM640N-66HL4M-BDV 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 AIKO AIKO-A655-MDE72Mw and Jinko Solar JKM640N-66HL4M-BDV?
AIKO AIKO-A655-MDE72Mw has a 30 years power warranty; Jinko Solar JKM640N-66HL4M-BDV 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-A655-MDE72Mw and Jinko Solar JKM640N-66HL4M-BDV bifacial panels?
Jinko Solar JKM640N-66HL4M-BDV is bifacial (captures light from both faces); AIKO AIKO-A655-MDE72Mw is monofacial. Bifacial panels work best on ground mounts or raised structures with a light-coloured surface underneath.
