According to our database: **Sharp GSD8K66H-740WT** has higher module efficiency (**23.82%** vs **23.53%**); **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 AE Solar CME-132BDS-730 and Sharp GSD8K66H-740WT? **AE Solar CME-132BDS-730** has a module efficiency of **23.53%**, while **Sharp GSD8K66H-740WT** is **23.82%**. Higher efficiency means more electricity from the same roof area - useful when space is limited. ### What cell technology does AE Solar CME-132BDS-730 use vs Sharp GSD8K66H-740WT? **AE Solar CME-132BDS-730** uses **TOPCon** cells; **Sharp GSD8K66H-740WT** uses **HJT**. 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 AE Solar CME-132BDS-730 and Sharp GSD8K66H-740WT? **AE Solar CME-132BDS-730** has a **30 years** power warranty; **Sharp GSD8K66H-740WT** 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 AE Solar CME-132BDS-730 and Sharp GSD8K66H-740WT bifacial panels? Both **AE Solar CME-132BDS-730** and **Sharp GSD8K66H-740WT** 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. ## Related comparisons - [AE Solar CME-132BDS-730 vs AE Solar CME-132BDS-730W](https://comparepv.com/compare/ae-solar-cme-132bds-730/ae-solar-cme-132bds-730w) - One difference: product warranty - [AE Solar CME-132BDS-730 vs AE Solar CME-132BDS-725](https://comparepv.com/compare/ae-solar-cme-132bds-730/ae-solar-cme-132bds-725) - The same specification on paper - [AE Solar CME-132BDS-730 vs AE Solar CME-132BDS-725W](https://comparepv.com/compare/ae-solar-cme-132bds-730/ae-solar-cme-132bds-725w) - One difference: product warranty - [AE Solar CME-132BDS-730 vs AE Solar CME-132BDS-720](https://comparepv.com/compare/ae-solar-cme-132bds-730/ae-solar-cme-132bds-720) - 3 differences, the largest is module efficiency - [AE Solar CME-132BDS-730 vs AE Solar CME-132BDS-720W](https://comparepv.com/compare/ae-solar-cme-132bds-730/ae-solar-cme-132bds-720w) - 4 differences, the largest is product warranty - [AE Solar CME-132BDS-730 vs AE Solar CME-132BDS-715](https://comparepv.com/compare/ae-solar-cme-132bds-730/ae-solar-cme-132bds-715) - 3 differences, the largest is module efficiency --- Source: https://comparepv.com/compare/ae-solar-cme-132bds-730/sharp-gsd8k66h-740wt Not in this file, on the page: the thirty-year yield curve year by year at a cell temperature you pick and a written summary generated on request.
