Lexron 415W vs Lexron 425W

Q: Which panel is better: Lexron 415W or Lexron 425W?

According to our database: Lexron 425W has higher module efficiency (21.37% vs 20.86%). See the full spec comparison and 30-year energy simulation above for a complete picture.

Q: What is the efficiency of Lexron 415W and Lexron 425W?

Lexron 415W has a module efficiency of 20.86%, while Lexron 425W is 21.37%. Higher efficiency means more electricity from the same roof area - useful when space is limited.

Q: What cell technology does Lexron 415W use vs Lexron 425W?

Lexron 415W uses PERC cells; Lexron 425W 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 415W and Lexron 425W?

Lexron 415W has a 30 years power warranty; Lexron 425W 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.

Thirty years of production

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.
