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 (-0.290 %/°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-465M/182R188-108+ GG or Luxor Solar LX-445M/182R188-108+ GG?
According to our database: Luxor Solar LX-465M/182R188-108+ GG has higher module efficiency (23.60% vs 22.60%). See the full spec comparison and 30-year energy simulation above for a complete picture.
What is the efficiency of Luxor Solar LX-465M/182R188-108+ GG and Luxor Solar LX-445M/182R188-108+ GG?
Luxor Solar LX-465M/182R188-108+ GG has a module efficiency of 23.60%, while Luxor Solar LX-445M/182R188-108+ GG is 22.60%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does Luxor Solar LX-465M/182R188-108+ GG use vs Luxor Solar LX-445M/182R188-108+ GG?
Luxor Solar LX-465M/182R188-108+ GG uses TOPCon cells; Luxor Solar LX-445M/182R188-108+ GG uses TOPCon. 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-465M/182R188-108+ GG and Luxor Solar LX-445M/182R188-108+ GG?
Luxor Solar LX-465M/182R188-108+ GG has a 30 years power warranty; Luxor Solar LX-445M/182R188-108+ 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-465M/182R188-108+ GG and Luxor Solar LX-445M/182R188-108+ GG bifacial panels?
Both Luxor Solar LX-465M/182R188-108+ GG and Luxor Solar LX-445M/182R188-108+ 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.
