Questions about this pairing
Which panel is better: Sharp GSD8K66H-740WT or AE Solar AE CME-132 720?
According to our database: Sharp GSD8K66H-740WT has higher module efficiency (23.82% vs 23.21%); Sharp GSD8K66H-740WT 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 Sharp GSD8K66H-740WT and AE Solar AE CME-132 720?
Sharp GSD8K66H-740WT has a module efficiency of 23.82%, while AE Solar AE CME-132 720 is 23.21%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does Sharp GSD8K66H-740WT use vs AE Solar AE CME-132 720?
Sharp GSD8K66H-740WT uses HJT cells; AE Solar AE CME-132 720 uses TOPCon. 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 Sharp GSD8K66H-740WT and AE Solar AE CME-132 720?
Sharp GSD8K66H-740WT has a 30 years power warranty; AE Solar AE CME-132 720 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 Sharp GSD8K66H-740WT and AE Solar AE CME-132 720 bifacial panels?
Sharp GSD8K66H-740WT is bifacial (captures light from both faces); AE Solar AE CME-132 720 is monofacial. Bifacial panels work best on ground mounts or raised structures with a light-coloured surface underneath.
