Questions about this pairing

Which panel is better: AE Solar MD-120BD-450 or AE Solar ME-132BD-660?
According to our database: AE Solar ME-132BD-660 has higher module efficiency (21.27% vs 20.88%); AE Solar ME-132BD-660 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-450 and AE Solar ME-132BD-660?
AE Solar MD-120BD-450 has a module efficiency of 20.88%, while AE Solar ME-132BD-660 is 21.27%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does AE Solar MD-120BD-450 use vs AE Solar ME-132BD-660?
AE Solar MD-120BD-450 uses PERC cells; AE Solar ME-132BD-660 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-450 and AE Solar ME-132BD-660?
AE Solar MD-120BD-450 has a 30 years power warranty; AE Solar ME-132BD-660 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-450 and AE Solar ME-132BD-660 bifacial panels?
Both AE Solar MD-120BD-450 and AE Solar ME-132BD-660 are bifacial - they capture reflected light from the ground, which can add 5-15% more annual energy on ground-mount or elevated rooftop installations with a light surface beneath.
