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: Lexron 405W or Lexron LEXRON 600W?
According to our database: Lexron LEXRON 600 W has higher module efficiency (23.23% vs 20.36%). See the full spec comparison and 30-year energy simulation above for a complete picture.
What is the efficiency of Lexron 405W and Lexron LEXRON 600W?
Lexron 405 W has a module efficiency of 20.36%, while Lexron LEXRON 600 W is 23.23%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does Lexron 405W use vs Lexron LEXRON 600W?
Lexron 405 W uses PERC cells; Lexron LEXRON 600 W 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 Lexron 405W and Lexron LEXRON 600W?
Lexron 405 W has a 30 years power warranty; Lexron LEXRON 600 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.
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.
