Questions about this pairing

Which panel is better: IBC Solar YH720W-33MHD/MH or AIKO AIKO-A805-GRH78Dw?
According to our database: AIKO AIKO-A805-GRH78Dw has higher module efficiency (25.10% vs 23.18%); AIKO AIKO-A805-GRH78Dw tolerates heat better (temp coeff -0.260%/°C vs -0.350%/°C). See the full spec comparison and 30-year energy simulation above for a complete picture.
What is the efficiency of IBC Solar YH720W-33MHD/MH and AIKO AIKO-A805-GRH78Dw?
IBC Solar YH720 W-33MHD/MH has a module efficiency of 23.18%, while AIKO AIKO-A805-GRH78Dw is 25.10%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does IBC Solar YH720W-33MHD/MH use vs AIKO AIKO-A805-GRH78Dw?
IBC Solar YH720 W-33MHD/MH uses TOPCon cells; AIKO AIKO-A805-GRH78Dw uses Back Contact. 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 IBC Solar YH720W-33MHD/MH and AIKO AIKO-A805-GRH78Dw?
IBC Solar YH720 W-33MHD/MH has a 30 years power warranty; AIKO AIKO-A805-GRH78Dw 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 IBC Solar YH720W-33MHD/MH and AIKO AIKO-A805-GRH78Dw bifacial panels?
Both IBC Solar YH720 W-33MHD/MH and AIKO AIKO-A805-GRH78Dw 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.
