Questions about this pairing
Which panel is better: AE Solar ME-132BD-655 or AE Solar MD-144BS-550W?
According to our database: AE Solar MD-144BS-550 W has higher module efficiency (21.31% vs 21.11%); AE Solar ME-132BD-655 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 ME-132BD-655 and AE Solar MD-144BS-550W?
AE Solar ME-132BD-655 has a module efficiency of 21.11%, while AE Solar MD-144BS-550 W is 21.31%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does AE Solar ME-132BD-655 use vs AE Solar MD-144BS-550W?
AE Solar ME-132BD-655 uses PERC cells; AE Solar MD-144BS-550 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 ME-132BD-655 and AE Solar MD-144BS-550W?
AE Solar ME-132BD-655 has a 30 years power warranty; AE Solar MD-144BS-550 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 ME-132BD-655 and AE Solar MD-144BS-550W bifacial panels?
Both AE Solar ME-132BD-655 and AE Solar MD-144BS-550 W 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.
