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: AE Solar AE CMD-108BDS-440 or AE Solar AE CMD-108BDE-435?
According to our database: AE Solar AE CMD-108BDS-440 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 AE CMD-108BDS-440 and AE Solar AE CMD-108BDE-435?
AE Solar AE CMD-108BDS-440 has a module efficiency of 22.57%, while AE Solar AE CMD-108BDE-435 is 22.31%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does AE Solar AE CMD-108BDS-440 use vs AE Solar AE CMD-108BDE-435?
AE Solar AE CMD-108BDS-440 uses TOPCon cells; AE Solar AE CMD-108BDE-435 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-108BDS-440 and AE Solar AE CMD-108BDE-435?
AE Solar AE CMD-108BDS-440 has a 30 years power warranty; AE Solar AE CMD-108BDE-435 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-108BDS-440 and AE Solar AE CMD-108BDE-435 bifacial panels?
Both AE Solar AE CMD-108BDS-440 and AE Solar AE CMD-108BDE-435 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.
