Lexron 410W vs Lexron 405W

Q: Which panel is better: Lexron 410W or Lexron 405W?

According to our database: Lexron 410W has higher module efficiency (20.61% vs 20.36%). See the full spec comparison and 30-year energy simulation above for a complete picture.

Q: What is the efficiency of Lexron 410W and Lexron 405W?

Lexron 410W has a module efficiency of 20.61%, while Lexron 405W is 20.36%. Higher efficiency means more electricity from the same roof area - useful when space is limited.

Q: What cell technology does Lexron 410W use vs Lexron 405W?

Lexron 410W uses PERC cells; Lexron 405W uses PERC. Modern n-type technologies (TOPCon, HJT, BC) typically deliver higher efficiency and lower degradation compared to older PERC (p-type) cells.

Q: What is the warranty on Lexron 410W and Lexron 405W?

Lexron 410W has a 30 years power warranty; Lexron 405W 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.

Each panel's own declared degradation curve, at 1,200 kWh/kWp a year

Cell temperature

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.
