What it means on a roof
Thirty years of production
Declared first-year losses, with 0.40% a year afterwards 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 CME-132 720 or AE Solar AE CMER-108BDE-505W?
According to our database: AE Solar AE CME-132 720 has higher module efficiency (23.21% vs 22.74%). See the full spec comparison and 30-year energy simulation above for a complete picture.
What is the efficiency of AE Solar AE CME-132 720 and AE Solar AE CMER-108BDE-505W?
AE Solar AE CME-132 720 has a module efficiency of 23.21%, while AE Solar AE CMER-108BDE-505 W is 22.74%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does AE Solar AE CME-132 720 use vs AE Solar AE CMER-108BDE-505W?
AE Solar AE CME-132 720 uses TOPCon cells; AE Solar AE CMER-108BDE-505 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 CME-132 720 and AE Solar AE CMER-108BDE-505W?
AE Solar AE CME-132 720 has a 30 years power warranty; AE Solar AE CMER-108BDE-505 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 CME-132 720 and AE Solar AE CMER-108BDE-505W bifacial panels?
AE Solar AE CMER-108BDE-505 W is bifacial (captures light from both faces); AE Solar AE CME-132 720 is monofacial. Bifacial panels work best on ground mounts or raised structures with a light-coloured surface underneath.
