Sharp GSD8K66H-740WT vs Luxor Solar LX-715M/210-132+ GG

Q: Which panel is better: Sharp GSD8K66H-740WT or Luxor Solar LX-715M/210-132+ GG?

According to our database: Sharp GSD8K66H-740WT has higher module efficiency (23.82% vs 23.23%); Luxor Solar LX-715M/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.

Q: What is the efficiency of Sharp GSD8K66H-740WT and Luxor Solar LX-715M/210-132+ GG?

Sharp GSD8K66H-740WT has a module efficiency of 23.82%, while Luxor Solar LX-715M/210-132+ GG is 23.23%. Higher efficiency means more electricity from the same roof area - useful when space is limited.

Q: What cell technology does Sharp GSD8K66H-740WT use vs Luxor Solar LX-715M/210-132+ GG?

Sharp GSD8K66H-740WT uses HJT cells; Luxor Solar LX-715M/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.

Q: What is the warranty on Sharp GSD8K66H-740WT and Luxor Solar LX-715M/210-132+ GG?

Sharp GSD8K66H-740WT has a 30 years power warranty; Luxor Solar LX-715M/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.

Q: Are Sharp GSD8K66H-740WT and Luxor Solar LX-715M/210-132+ GG bifacial panels?

Both Sharp GSD8K66H-740WT and Luxor Solar LX-715M/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.
