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 CME-132BDS-720 or AE Solar AExxxCMD-108BDE?
According to our database: AE Solar CME-132BDS-720 has higher module efficiency (23.21% vs 22.57%). See the full spec comparison and 30-year energy simulation above for a complete picture.
What is the efficiency of AE Solar CME-132BDS-720 and AE Solar AExxxCMD-108BDE?
AE Solar CME-132BDS-720 has a module efficiency of 23.21%, while AE Solar AExxxCMD-108BDE is 22.57%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does AE Solar CME-132BDS-720 use vs AE Solar AExxxCMD-108BDE?
AE Solar CME-132BDS-720 uses TOPCon cells; AE Solar AExxxCMD-108BDE 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 CME-132BDS-720 and AE Solar AExxxCMD-108BDE?
AE Solar CME-132BDS-720 has a 30 years power warranty; AE Solar AExxxCMD-108BDE 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 CME-132BDS-720 and AE Solar AExxxCMD-108BDE bifacial panels?
Both AE Solar CME-132BDS-720 and AE Solar AExxxCMD-108BDE 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.
