What it means on a roof
Thirty years of production
Declared first-year losses, with 0.40% a year afterwards assumed for both panels, 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 MD-120BS-460 or AE Solar AE MD-120BD-460?
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 MD-120BS-460 and AE Solar AE MD-120BD-460?
AE Solar MD-120BS-460 has a module efficiency of 21.35%, while AE Solar AE MD-120BD-460 is 21.35%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does AE Solar MD-120BS-460 use vs AE Solar AE MD-120BD-460?
AE Solar MD-120BS-460 uses PERC cells; AE Solar AE MD-120BD-460 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-120BS-460 and AE Solar AE MD-120BD-460?
AE Solar MD-120BS-460 has a 30 years power warranty; AE Solar AE MD-120BD-460 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-120BS-460 and AE Solar AE MD-120BD-460 bifacial panels?
Both AE Solar MD-120BS-460 and AE Solar AE MD-120BD-460 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.
