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-144 530W-550W (550W) or AE Solar AE MD-144 530W-550W (540W)?
According to our database: AE Solar AE MD-144 530 W-550 W (550 W) has higher module efficiency (21.31% vs 20.92%). See the full spec comparison and 30-year energy simulation above for a complete picture.
What is the efficiency of AE Solar AE MD-144 530W-550W (550W) and AE Solar AE MD-144 530W-550W (540W)?
AE Solar AE MD-144 530 W-550 W (550 W) has a module efficiency of 21.31%, while AE Solar AE MD-144 530 W-550 W (540 W) is 20.92%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does AE Solar AE MD-144 530W-550W (550W) use vs AE Solar AE MD-144 530W-550W (540W)?
AE Solar AE MD-144 530 W-550 W (550 W) uses PERC cells; AE Solar AE MD-144 530 W-550 W (540 W) 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-144 530W-550W (550W) and AE Solar AE MD-144 530W-550W (540W)?
AE Solar AE MD-144 530 W-550 W (550 W) has a 30 years power warranty; AE Solar AE MD-144 530 W-550 W (540 W) 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.
