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 AE440CMD-108BDE or AE Solar CMD-108BDS-435W?
According to our database: AE Solar AE440CMD-108BDE has higher module efficiency (22.57% vs 22.31%). See the full spec comparison and 30-year energy simulation above for a complete picture.
What is the efficiency of AE Solar AE440CMD-108BDE and AE Solar CMD-108BDS-435W?
AE Solar AE440CMD-108BDE has a module efficiency of 22.57%, while AE Solar CMD-108BDS-435 W is 22.31%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does AE Solar AE440CMD-108BDE use vs AE Solar CMD-108BDS-435W?
AE Solar AE440CMD-108BDE uses TOPCon cells; AE Solar CMD-108BDS-435 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 AE440CMD-108BDE and AE Solar CMD-108BDS-435W?
AE Solar AE440CMD-108BDE has a 30 years power warranty; AE Solar CMD-108BDS-435 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 AE440CMD-108BDE and AE Solar CMD-108BDS-435W bifacial panels?
Both AE Solar AE440CMD-108BDE and AE Solar CMD-108BDS-435 W 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.
