Questions about this pairing

Which panel is better: AIKO AIKO-A790-GRH78Dw or Luxor Solar LX-720M/210-132+ GG?
According to our database: AIKO AIKO-A790-GRH78Dw has higher module efficiency (24.60% 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 AIKO AIKO-A790-GRH78Dw and Luxor Solar LX-720M/210-132+ GG?
AIKO AIKO-A790-GRH78Dw has a module efficiency of 24.60%, 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 AIKO AIKO-A790-GRH78Dw use vs Luxor Solar LX-720M/210-132+ GG?
AIKO AIKO-A790-GRH78Dw uses Back Contact 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 AIKO AIKO-A790-GRH78Dw and Luxor Solar LX-720M/210-132+ GG?
AIKO AIKO-A790-GRH78Dw 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 AIKO AIKO-A790-GRH78Dw and Luxor Solar LX-720M/210-132+ GG bifacial panels?
Both AIKO AIKO-A790-GRH78Dw 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.
