Questions about this pairing

Which panel is better: Canadian Solar CS6W-585T or AIKO AIKO-A650-GRH66Dw?
According to our database: AIKO AIKO-A650-GRH66Dw has higher module efficiency (24.10% vs 22.60%); AIKO AIKO-A650-GRH66Dw tolerates heat better (temp coeff -0.260%/°C vs -0.290%/°C). See the full spec comparison and 30-year energy simulation above for a complete picture.
What is the efficiency of Canadian Solar CS6W-585T and AIKO AIKO-A650-GRH66Dw?
Canadian Solar CS6W-585T has a module efficiency of 22.60%, while AIKO AIKO-A650-GRH66Dw is 24.10%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does Canadian Solar CS6W-585T use vs AIKO AIKO-A650-GRH66Dw?
Canadian Solar CS6W-585T uses TOPCon cells; AIKO AIKO-A650-GRH66Dw 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 Canadian Solar CS6W-585T and AIKO AIKO-A650-GRH66Dw?
Canadian Solar CS6W-585T has a 30 years power warranty; AIKO AIKO-A650-GRH66Dw 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 Canadian Solar CS6W-585T and AIKO AIKO-A650-GRH66Dw bifacial panels?
AIKO AIKO-A650-GRH66Dw is bifacial (captures light from both faces); Canadian Solar CS6W-585T is monofacial. Bifacial panels work best on ground mounts or raised structures with a light-coloured surface underneath.
