What it means on a roof
Thirty years of production
A 1.0% first-year loss then 0.40% a year, assumed for both panels, at 1,200 kWh/kWp a year
Same temp coeff. for both panels (-0.260 %/°C), so a warmer roof scales both curves by the same factor: the totals fall together and neither panel gains on the other.

Questions about this pairing
Which panel is better: AIKO AIKO-A630-MAE72Dw or AIKO AIKO-A800-GRH78Dw?
According to our database: AIKO AIKO-A800-GRH78Dw has higher module efficiency (24.90% vs 24.40%). See the full spec comparison and 30-year energy simulation above for a complete picture.
What is the efficiency of AIKO AIKO-A630-MAE72Dw and AIKO AIKO-A800-GRH78Dw?
AIKO AIKO-A630-MAE72Dw has a module efficiency of 24.40%, while AIKO AIKO-A800-GRH78Dw is 24.90%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does AIKO AIKO-A630-MAE72Dw use vs AIKO AIKO-A800-GRH78Dw?
AIKO AIKO-A630-MAE72Dw uses Back Contact cells; AIKO AIKO-A800-GRH78Dw 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-A630-MAE72Dw and AIKO AIKO-A800-GRH78Dw?
AIKO AIKO-A630-MAE72Dw has a 30 years power warranty; AIKO AIKO-A800-GRH78Dw 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-A630-MAE72Dw and AIKO AIKO-A800-GRH78Dw bifacial panels?
AIKO AIKO-A800-GRH78Dw is bifacial (captures light from both faces); AIKO AIKO-A630-MAE72Dw is monofacial. Bifacial panels work best on ground mounts or raised structures with a light-coloured surface underneath.
