Lexron 420W vs Lexron 410W

Q: Which panel is better: Lexron 420W or Lexron 410W?

According to our database: Lexron 420W has higher module efficiency (21.12% vs 20.61%). See the full spec comparison and 30-year energy simulation above for a complete picture.

Q: What is the efficiency of Lexron 420W and Lexron 410W?

Lexron 420W has a module efficiency of 21.12%, while Lexron 410W is 20.61%. Higher efficiency means more electricity from the same roof area - useful when space is limited.

Q: What cell technology does Lexron 420W use vs Lexron 410W?

Lexron 420W uses PERC cells; Lexron 410W 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 420W and Lexron 410W?

Lexron 420W has a 30 years power warranty; Lexron 410W 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.
