Questions about this pairing

Which panel is better: Luxor Solar LX - 435 M/182-108+ GG or Luxor Solar LX-555 M/182-144+?
According to our database: Luxor Solar LX - 435 M/182-108+ GG has higher module efficiency (22.61% vs 21.74%); Luxor Solar LX - 435 M/182-108+ GG tolerates heat better (temp coeff -0.240%/°C vs -0.300%/°C). See the full spec comparison and 30-year energy simulation above for a complete picture.
What is the efficiency of Luxor Solar LX - 435 M/182-108+ GG and Luxor Solar LX-555 M/182-144+?
Luxor Solar LX - 435 M/182-108+ GG has a module efficiency of 22.61%, while Luxor Solar LX-555 M/182-144+ is 21.74%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does Luxor Solar LX - 435 M/182-108+ GG use vs Luxor Solar LX-555 M/182-144+?
Luxor Solar LX - 435 M/182-108+ GG uses HJT cells; Luxor Solar LX-555 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 - 435 M/182-108+ GG and Luxor Solar LX-555 M/182-144+?
Luxor Solar LX - 435 M/182-108+ GG has a 30 years power warranty; Luxor Solar LX-555 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 - 435 M/182-108+ GG and Luxor Solar LX-555 M/182-144+ bifacial panels?
Luxor Solar LX - 435 M/182-108+ GG is bifacial (captures light from both faces); Luxor Solar LX-555 M/182-144+ is monofacial. Bifacial panels work best on ground mounts or raised structures with a light-coloured surface underneath.
