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 (-0.290 %/°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: AE Solar AE CMD-108-440 or AE Solar CMD-108BDS-440W?
According to our database: both panels are closely matched on key specs - the decision often comes down to price and local availability. See the full spec comparison and 30-year energy simulation above for a complete picture.
What is the efficiency of AE Solar AE CMD-108-440 and AE Solar CMD-108BDS-440W?
AE Solar AE CMD-108-440 has a module efficiency of 22.57%, while AE Solar CMD-108BDS-440 W is 22.57%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does AE Solar AE CMD-108-440 use vs AE Solar CMD-108BDS-440W?
AE Solar AE CMD-108-440 uses TOPCon cells; AE Solar CMD-108BDS-440 W uses TOPCon. 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 AE Solar AE CMD-108-440 and AE Solar CMD-108BDS-440W?
AE Solar AE CMD-108-440 has a 30 years power warranty; AE Solar CMD-108BDS-440 W 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 AE Solar AE CMD-108-440 and AE Solar CMD-108BDS-440W bifacial panels?
AE Solar CMD-108BDS-440 W is bifacial (captures light from both faces); AE Solar AE CMD-108-440 is monofacial. Bifacial panels work best on ground mounts or raised structures with a light-coloured surface underneath.
