Questions about this pairing
Which panel is better: AIKO AIKO-A800-GRH78Dw or AIKO AIKO-A-610-MAH72Mw?
According to our database: AIKO AIKO-A800-GRH78Dw has higher module efficiency (24.90% vs 23.60%); AIKO AIKO-A800-GRH78Dw 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-A800-GRH78Dw and AIKO AIKO-A-610-MAH72Mw?
AIKO AIKO-A800-GRH78Dw has a module efficiency of 24.90%, while AIKO AIKO-A-610-MAH72Mw is 23.60%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does AIKO AIKO-A800-GRH78Dw use vs AIKO AIKO-A-610-MAH72Mw?
AIKO AIKO-A800-GRH78Dw uses Back Contact cells; AIKO AIKO-A-610-MAH72Mw 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 AIKO AIKO-A800-GRH78Dw and AIKO AIKO-A-610-MAH72Mw?
AIKO AIKO-A800-GRH78Dw has a 30 years power warranty; AIKO AIKO-A-610-MAH72Mw 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-A800-GRH78Dw and AIKO AIKO-A-610-MAH72Mw bifacial panels?
AIKO AIKO-A800-GRH78Dw is bifacial (captures light from both faces); AIKO AIKO-A-610-MAH72Mw is monofacial. Bifacial panels work best on ground mounts or raised structures with a light-coloured surface underneath.
