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-A610-MAH72Dw or AIKO AIKO-A795-GRH78Dw?
According to our database: AIKO AIKO-A795-GRH78Dw has higher module efficiency (24.80% vs 23.60%). See the full spec comparison and 30-year energy simulation above for a complete picture.
What is the efficiency of AIKO AIKO-A610-MAH72Dw and AIKO AIKO-A795-GRH78Dw?
AIKO AIKO-A610-MAH72Dw has a module efficiency of 23.60%, while AIKO AIKO-A795-GRH78Dw is 24.80%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does AIKO AIKO-A610-MAH72Dw use vs AIKO AIKO-A795-GRH78Dw?
AIKO AIKO-A610-MAH72Dw uses Back Contact cells; AIKO AIKO-A795-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-A610-MAH72Dw and AIKO AIKO-A795-GRH78Dw?
AIKO AIKO-A610-MAH72Dw has a 30 years power warranty; AIKO AIKO-A795-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-A610-MAH72Dw and AIKO AIKO-A795-GRH78Dw bifacial panels?
Both AIKO AIKO-A610-MAH72Dw and AIKO AIKO-A795-GRH78Dw are bifacial - they capture reflected light from the ground, which can add 5-15% more annual energy on ground-mount or elevated rooftop installations with a light surface beneath.
