Questions about this pairing
Which panel is better: Luxor Solar LX - 420 M/182-108+ GG or Luxor Solar LX-720M/210-132+ GG?
According to our database: Luxor Solar LX-720M/210-132+ GG has higher module efficiency (23.39% vs 21.84%); Luxor Solar LX-720M/210-132+ 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 - 420 M/182-108+ GG and Luxor Solar LX-720M/210-132+ GG?
Luxor Solar LX - 420 M/182-108+ GG has a module efficiency of 21.84%, while Luxor Solar LX-720M/210-132+ GG is 23.39%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does Luxor Solar LX - 420 M/182-108+ GG use vs Luxor Solar LX-720M/210-132+ GG?
Luxor Solar LX - 420 M/182-108+ GG uses TOPCon cells; Luxor Solar LX-720M/210-132+ GG uses HJT. 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 - 420 M/182-108+ GG and Luxor Solar LX-720M/210-132+ GG?
Luxor Solar LX - 420 M/182-108+ GG has a 30 years power warranty; Luxor Solar LX-720M/210-132+ GG 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.
Are Luxor Solar LX - 420 M/182-108+ GG and Luxor Solar LX-720M/210-132+ GG bifacial panels?
Both Luxor Solar LX - 420 M/182-108+ GG and Luxor Solar LX-720M/210-132+ GG are bifacial - they capture reflected light from the ground, which can add 5-15% more annual energy on ground-mount or elevated rooftop installations with a light surface beneath.
