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 (-0.300 %/°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: Luxor Solar LX-435M/182-108+GG or Luxor Solar LX-575 M/182-144+?
According to our database: Luxor Solar LX-435M/182-108+GG has higher module efficiency (22.61% vs 22.51%). See the full spec comparison and 30-year energy simulation above for a complete picture.
What is the efficiency of Luxor Solar LX-435M/182-108+GG and Luxor Solar LX-575 M/182-144+?
Luxor Solar LX-435M/182-108+GG has a module efficiency of 22.61%, while Luxor Solar LX-575 M/182-144+ is 22.51%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does Luxor Solar LX-435M/182-108+GG use vs Luxor Solar LX-575 M/182-144+?
Luxor Solar LX-435M/182-108+GG uses TOPCon cells; Luxor Solar LX-575 M/182-144+ uses N-type. 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 Luxor Solar LX-435M/182-108+GG and Luxor Solar LX-575 M/182-144+?
Luxor Solar LX-435M/182-108+GG has a 30 years power warranty; Luxor Solar LX-575 M/182-144+ 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.
Are Luxor Solar LX-435M/182-108+GG and Luxor Solar LX-575 M/182-144+ bifacial panels?
Luxor Solar LX-435M/182-108+GG is bifacial (captures light from both faces); Luxor Solar LX-575 M/182-144+ is monofacial. Bifacial panels work best on ground mounts or raised structures with a light-coloured surface underneath.
