AE Solar AE CMD-144BDS-570 vs AE Solar AE CMD-108BDS 440W

Q: Which panel is better: AE Solar AE CMD-144BDS-570 or AE Solar AE CMD-108BDS 440W?

According to our database: AE Solar AE CMD-108BDS 440W has higher module efficiency (22.57% vs 22.08%). See the full spec comparison and 30-year energy simulation above for a complete picture.

Q: What is the efficiency of AE Solar AE CMD-144BDS-570 and AE Solar AE CMD-108BDS 440W?

AE Solar AE CMD-144BDS-570 has a module efficiency of 22.08%, while AE Solar AE CMD-108BDS 440W is 22.57%. Higher efficiency means more electricity from the same roof area - useful when space is limited.

Q: What cell technology does AE Solar AE CMD-144BDS-570 use vs AE Solar AE CMD-108BDS 440W?

AE Solar AE CMD-144BDS-570 uses TOPCon cells; AE Solar AE CMD-108BDS 440W uses TOPCon. Modern n-type technologies (TOPCon, HJT, BC) typically deliver higher efficiency and lower degradation compared to older PERC (p-type) cells.

Q: What is the warranty on AE Solar AE CMD-144BDS-570 and AE Solar AE CMD-108BDS 440W?

AE Solar AE CMD-144BDS-570 has a 30 years power warranty; AE Solar AE CMD-108BDS 440W 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.

Q: Are AE Solar AE CMD-144BDS-570 and AE Solar AE CMD-108BDS 440W bifacial panels?

Both AE Solar AE CMD-144BDS-570 and AE Solar AE CMD-108BDS 440W 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.
