Questions about this pairing
Which panel is better: AIKO AIKO-A805-GRH78Dw or Sunplus 750?
According to our database: AIKO AIKO-A805-GRH78Dw has higher module efficiency (25.10% vs 24.10%); AIKO AIKO-A805-GRH78Dw tolerates heat better (temp coeff -0.260%/°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 AIKO AIKO-A805-GRH78Dw and Sunplus 750?
AIKO AIKO-A805-GRH78Dw has a module efficiency of 25.10%, while Sunplus 750 is 24.10%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does AIKO AIKO-A805-GRH78Dw use vs Sunplus 750?
AIKO AIKO-A805-GRH78Dw uses Back Contact cells; Sunplus 750 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-A805-GRH78Dw and Sunplus 750?
AIKO AIKO-A805-GRH78Dw has a 30 years power warranty; Sunplus 750 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-A805-GRH78Dw and Sunplus 750 bifacial panels?
Both AIKO AIKO-A805-GRH78Dw and Sunplus 750 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.
