Questions about this pairing
Which panel is better: AE Solar MD-120BD-440 or AE Solar AE ME-132 655W?
According to our database: AE Solar AE ME-132 655 W has higher module efficiency (21.11% vs 20.42%); AE Solar AE ME-132 655 W tolerates heat better (temp coeff -0.340%/°C vs -0.350%/°C). See the full spec comparison and 30-year energy simulation above for a complete picture.
What is the efficiency of AE Solar MD-120BD-440 and AE Solar AE ME-132 655W?
AE Solar MD-120BD-440 has a module efficiency of 20.42%, while AE Solar AE ME-132 655 W is 21.11%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does AE Solar MD-120BD-440 use vs AE Solar AE ME-132 655W?
AE Solar MD-120BD-440 uses PERC cells; AE Solar AE ME-132 655 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 MD-120BD-440 and AE Solar AE ME-132 655W?
AE Solar MD-120BD-440 has a 30 years power warranty; AE Solar AE ME-132 655 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 MD-120BD-440 and AE Solar AE ME-132 655W bifacial panels?
AE Solar MD-120BD-440 is bifacial (captures light from both faces); AE Solar AE ME-132 655 W is monofacial. Bifacial panels work best on ground mounts or raised structures with a light-coloured surface underneath.
