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 (-0.290 %/°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 CMD-144 590W or AE Solar AE CMD-144BDS-595?
According to our database: AE Solar AE CMD-144BDS-595 has higher module efficiency (23.05% vs 22.86%). See the full spec comparison and 30-year energy simulation above for a complete picture.
What is the efficiency of AE Solar AE CMD-144 590W and AE Solar AE CMD-144BDS-595?
AE Solar AE CMD-144 590 W has a module efficiency of 22.86%, while AE Solar AE CMD-144BDS-595 is 23.05%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does AE Solar AE CMD-144 590W use vs AE Solar AE CMD-144BDS-595?
AE Solar AE CMD-144 590 W uses TOPCon cells; AE Solar AE CMD-144BDS-595 uses TOPCon. 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 CMD-144 590W and AE Solar AE CMD-144BDS-595?
AE Solar AE CMD-144 590 W has a 30 years power warranty; AE Solar AE CMD-144BDS-595 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 CMD-144 590W and AE Solar AE CMD-144BDS-595 bifacial panels?
AE Solar AE CMD-144BDS-595 is bifacial (captures light from both faces); AE Solar AE CMD-144 590 W is monofacial. Bifacial panels work best on ground mounts or raised structures with a light-coloured surface underneath.
