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 AE MD-120BD-455 or AE Solar MD-120BS-460?
According to our database: AE Solar MD-120BS-460 has higher module efficiency (21.35% vs 21.11%). See the full spec comparison and 30-year energy simulation above for a complete picture.
What is the efficiency of AE Solar AE MD-120BD-455 and AE Solar MD-120BS-460?
AE Solar AE MD-120BD-455 has a module efficiency of 21.11%, while AE Solar MD-120BS-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 AE MD-120BD-455 use vs AE Solar MD-120BS-460?
AE Solar AE MD-120BD-455 uses PERC cells; AE Solar MD-120BS-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 AE MD-120BD-455 and AE Solar MD-120BS-460?
AE Solar AE MD-120BD-455 has a 30 years power warranty; AE Solar MD-120BS-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 AE MD-120BD-455 and AE Solar MD-120BS-460 bifacial panels?
Both AE Solar AE MD-120BD-455 and AE Solar MD-120BS-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.
