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 MD-120BD-460 or AE Solar MD-120BD-445?
According to our database: AE Solar MD-120BD-460 has higher module efficiency (21.35% vs 20.65%). See the full spec comparison and 30-year energy simulation above for a complete picture.
What is the efficiency of AE Solar MD-120BD-460 and AE Solar MD-120BD-445?
AE Solar MD-120BD-460 has a module efficiency of 21.35%, while AE Solar MD-120BD-445 is 20.65%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does AE Solar MD-120BD-460 use vs AE Solar MD-120BD-445?
AE Solar MD-120BD-460 uses PERC cells; AE Solar MD-120BD-445 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-460 and AE Solar MD-120BD-445?
AE Solar MD-120BD-460 has a 30 years power warranty; AE Solar MD-120BD-445 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-460 and AE Solar MD-120BD-445 bifacial panels?
Both AE Solar MD-120BD-460 and AE Solar MD-120BD-445 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.
