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 (-0.260 %/°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-A655-GRH66Dw or Longi Solar LR7-54HVH-500M?
According to our database: Longi Solar LR7-54HVH-500M has higher module efficiency (24.50% vs 24.20%). See the full spec comparison and 30-year energy simulation above for a complete picture.
What is the efficiency of AIKO AIKO-A655-GRH66Dw and Longi Solar LR7-54HVH-500M?
AIKO AIKO-A655-GRH66Dw has a module efficiency of 24.20%, while Longi Solar LR7-54HVH-500M is 24.50%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does AIKO AIKO-A655-GRH66Dw use vs Longi Solar LR7-54HVH-500M?
AIKO AIKO-A655-GRH66Dw uses Back Contact cells; Longi Solar LR7-54HVH-500M 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-GRH66Dw and Longi Solar LR7-54HVH-500M?
AIKO AIKO-A655-GRH66Dw has a 30 years power warranty; Longi Solar LR7-54HVH-500M 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-GRH66Dw and Longi Solar LR7-54HVH-500M bifacial panels?
AIKO AIKO-A655-GRH66Dw is bifacial (captures light from both faces); Longi Solar LR7-54HVH-500M is monofacial. Bifacial panels work best on ground mounts or raised structures with a light-coloured surface underneath.
