Questions about this pairing
Which panel is better: Luxor Solar LX-720M/210-132+GG or Sharp GSD8K66H-740WT?
According to our database: Sharp GSD8K66H-740WT has higher module efficiency (23.82% vs 23.39%); Luxor Solar LX-720M/210-132+GG tolerates heat better (temp coeff -0.240%/°C vs -0.260%/°C). See the full spec comparison and 30-year energy simulation above for a complete picture.
What is the efficiency of Luxor Solar LX-720M/210-132+GG and Sharp GSD8K66H-740WT?
Luxor Solar LX-720M/210-132+GG has a module efficiency of 23.39%, while Sharp GSD8K66H-740WT is 23.82%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does Luxor Solar LX-720M/210-132+GG use vs Sharp GSD8K66H-740WT?
Luxor Solar LX-720M/210-132+GG uses HJT cells; Sharp GSD8K66H-740WT 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-720M/210-132+GG and Sharp GSD8K66H-740WT?
Luxor Solar LX-720M/210-132+GG has a 30 years power warranty; Sharp GSD8K66H-740WT 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-720M/210-132+GG and Sharp GSD8K66H-740WT bifacial panels?
Both Luxor Solar LX-720M/210-132+GG and Sharp GSD8K66H-740WT 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.
