Questions about this pairing

Which panel is better: AE Solar CME-132BDS-725 or AE Solar AE ME-132 640W?
According to our database: AE Solar CME-132BDS-725 has higher module efficiency (23.37% vs 20.63%); AE Solar CME-132BDS-725 tolerates heat better (temp coeff -0.290%/°C vs -0.340%/°C). See the full spec comparison and 30-year energy simulation above for a complete picture.
What is the efficiency of AE Solar CME-132BDS-725 and AE Solar AE ME-132 640W?
AE Solar CME-132BDS-725 has a module efficiency of 23.37%, while AE Solar AE ME-132 640 W is 20.63%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does AE Solar CME-132BDS-725 use vs AE Solar AE ME-132 640W?
AE Solar CME-132BDS-725 uses TOPCon cells; AE Solar AE ME-132 640 W uses PERC. 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-725 and AE Solar AE ME-132 640W?
AE Solar CME-132BDS-725 has a 30 years power warranty; AE Solar AE ME-132 640 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 CME-132BDS-725 and AE Solar AE ME-132 640W bifacial panels?
AE Solar CME-132BDS-725 is bifacial (captures light from both faces); AE Solar AE ME-132 640 W is monofacial. Bifacial panels work best on ground mounts or raised structures with a light-coloured surface underneath.
