What it means on a roof

Thirty years of production
Each panel's own declared degradation curve, at 1,200 kWh/kWp a year
Same temp coeff. for both panels (-0.290 %/°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-A620-MAH72Dw G or AIKO AIKO-A615-MAH72Dw G?
According to our database: AIKO AIKO-A620-MAH72Dw G has higher module efficiency (23.50% vs 23.30%). See the full spec comparison and 30-year energy simulation above for a complete picture.
What is the efficiency of AIKO AIKO-A620-MAH72Dw G and AIKO AIKO-A615-MAH72Dw G?
AIKO AIKO-A620-MAH72Dw G has a module efficiency of 23.50%, while AIKO AIKO-A615-MAH72Dw G is 23.30%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does AIKO AIKO-A620-MAH72Dw G use vs AIKO AIKO-A615-MAH72Dw G?
AIKO AIKO-A620-MAH72Dw G uses N-type cells; AIKO AIKO-A615-MAH72Dw G 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-A620-MAH72Dw G and AIKO AIKO-A615-MAH72Dw G?
AIKO AIKO-A620-MAH72Dw G has a 30 years power warranty; AIKO AIKO-A615-MAH72Dw G 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-A620-MAH72Dw G and AIKO AIKO-A615-MAH72Dw G bifacial panels?
Both AIKO AIKO-A620-MAH72Dw G and AIKO AIKO-A615-MAH72Dw G 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.
