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 CMER-108BDE-505W or AE Solar CME-132-725W?
According to our database: AE Solar CME-132-725 W has higher module efficiency (23.37% 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 CMER-108BDE-505W and AE Solar CME-132-725W?
AE Solar AE CMER-108BDE-505 W has a module efficiency of 22.74%, while AE Solar CME-132-725 W is 23.37%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does AE Solar AE CMER-108BDE-505W use vs AE Solar CME-132-725W?
AE Solar AE CMER-108BDE-505 W uses TOPCon cells; AE Solar CME-132-725 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 CMER-108BDE-505W and AE Solar CME-132-725W?
AE Solar AE CMER-108BDE-505 W has a 30 years power warranty; AE Solar CME-132-725 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 CMER-108BDE-505W and AE Solar CME-132-725W bifacial panels?
AE Solar AE CMER-108BDE-505 W is bifacial (captures light from both faces); AE Solar CME-132-725 W is monofacial. Bifacial panels work best on ground mounts or raised structures with a light-coloured surface underneath.
