Questions about this pairing

Which panel is better: AIKO M545M-144 or AIKO AIKO-A795-GRH78Dw?
According to our database: AIKO AIKO-A795-GRH78Dw has higher module efficiency (24.80% vs 21.10%); AIKO AIKO-A795-GRH78Dw tolerates heat better (temp coeff -0.260%/°C vs -0.360%/°C). See the full spec comparison and 30-year energy simulation above for a complete picture.
What is the efficiency of AIKO M545M-144 and AIKO AIKO-A795-GRH78Dw?
AIKO M545M-144 has a module efficiency of 21.10%, while AIKO AIKO-A795-GRH78Dw is 24.80%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does AIKO M545M-144 use vs AIKO AIKO-A795-GRH78Dw?
AIKO M545M-144 uses PERC cells; AIKO AIKO-A795-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 AIKO M545M-144 and AIKO AIKO-A795-GRH78Dw?
AIKO M545M-144 has a 25 years power warranty; AIKO AIKO-A795-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 AIKO M545M-144 and AIKO AIKO-A795-GRH78Dw bifacial panels?
AIKO AIKO-A795-GRH78Dw is bifacial (captures light from both faces); AIKO M545M-144 is monofacial. Bifacial panels work best on ground mounts or raised structures with a light-coloured surface underneath.
