What it means on a roof

Thirty years of production
Each panel's own declared degradation curve, at 1,200 kWh/kWp a year
Same temp coeff. for both panels (-0.350 %/°C), so a warmer roof scales both curves by the same factor: the totals fall together and neither panel gains on the other.

Questions about this pairing

Which panel is better: AE Solar AE MD-144BD-550 or AE Solar AE MD-144-550?
According to our database: both panels are closely matched on key specs - the decision often comes down to price and local availability. See the full spec comparison and 30-year energy simulation above for a complete picture.
What is the efficiency of AE Solar AE MD-144BD-550 and AE Solar AE MD-144-550?
AE Solar AE MD-144BD-550 has a module efficiency of 21.31%, while AE Solar AE MD-144-550 is 21.31%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does AE Solar AE MD-144BD-550 use vs AE Solar AE MD-144-550?
AE Solar AE MD-144BD-550 uses PERC cells; AE Solar AE MD-144-550 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 AE MD-144BD-550 and AE Solar AE MD-144-550?
AE Solar AE MD-144BD-550 has a 30 years power warranty; AE Solar AE MD-144-550 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 MD-144BD-550 and AE Solar AE MD-144-550 bifacial panels?
AE Solar AE MD-144BD-550 is bifacial (captures light from both faces); AE Solar AE MD-144-550 is monofacial. Bifacial panels work best on ground mounts or raised structures with a light-coloured surface underneath.
