Questions about this pairing
Which panel is better: AE Solar AE ME-132 645W or AE Solar CME-132BDS-730?
According to our database: AE Solar CME-132BDS-730 has higher module efficiency (23.53% vs 20.79%); AE Solar CME-132BDS-730 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 AE ME-132 645W and AE Solar CME-132BDS-730?
AE Solar AE ME-132 645 W has a module efficiency of 20.79%, while AE Solar CME-132BDS-730 is 23.53%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does AE Solar AE ME-132 645W use vs AE Solar CME-132BDS-730?
AE Solar AE ME-132 645 W uses PERC cells; AE Solar CME-132BDS-730 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 ME-132 645W and AE Solar CME-132BDS-730?
AE Solar AE ME-132 645 W has a 30 years power warranty; AE Solar CME-132BDS-730 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 ME-132 645W and AE Solar CME-132BDS-730 bifacial panels?
AE Solar CME-132BDS-730 is bifacial (captures light from both faces); AE Solar AE ME-132 645 W is monofacial. Bifacial panels work best on ground mounts or raised structures with a light-coloured surface underneath.
