What it means on a roof

Thirty years of production
A 1.0% first-year loss then 0.40% a year, assumed for both panels, at 1,200 kWh/kWp a year
Same temp coeff. for both panels (-0.370 %/°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: Daxieworld AOX-144M10FL 520W or Daxieworld AOX-144M10FL 525W?
According to our database: Daxieworld AOX-144M10FL 525 W has higher module efficiency (19.73% vs 19.54%). See the full spec comparison and 30-year energy simulation above for a complete picture.
What is the efficiency of Daxieworld AOX-144M10FL 520W and Daxieworld AOX-144M10FL 525W?
Daxieworld AOX-144M10FL 520 W has a module efficiency of 19.54%, while Daxieworld AOX-144M10FL 525 W is 19.73%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does Daxieworld AOX-144M10FL 520W use vs Daxieworld AOX-144M10FL 525W?
Daxieworld AOX-144M10FL 520 W uses PERC cells; Daxieworld AOX-144M10FL 525 W uses Flexible. 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 Daxieworld AOX-144M10FL 520W and Daxieworld AOX-144M10FL 525W?
Daxieworld AOX-144M10FL 520 W has a 25 years power warranty; Daxieworld AOX-144M10FL 525 W has a 25 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.

Every figure here is from the manufacturers' own datasheets - a dash means the value is not published, never an estimate. The thirty-year projection and the temperature scenarios are calculations from those figures, and each states its assumption above.
