According to our database: **AE Solar AE CME-132 720** has higher module efficiency (**23.21%** vs **22.57%**). See the full spec comparison and 30-year energy simulation above for a complete picture. ### What is the efficiency of AE Solar AE CME-132 720 and AE Solar AE440CMD-108BDE? **AE Solar AE CME-132 720** has a module efficiency of **23.21%**, while **AE Solar AE440CMD-108BDE** is **22.57%**. Higher efficiency means more electricity from the same roof area - useful when space is limited. ### What cell technology does AE Solar AE CME-132 720 use vs AE Solar AE440CMD-108BDE? **AE Solar AE CME-132 720** uses **TOPCon** cells; **AE Solar AE440CMD-108BDE** 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 AE Solar AE CME-132 720 and AE Solar AE440CMD-108BDE? **AE Solar AE CME-132 720** has a **30 years** power warranty; **AE Solar AE440CMD-108BDE** 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 AE CME-132 720 and AE Solar AE440CMD-108BDE bifacial panels? **AE Solar AE440CMD-108BDE** 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. ## Related comparisons - [AE Solar AE CME-132 720 vs AE Solar CME-132BDS-730](https://comparepv.com/compare/ae-solar-ae-cme-132-720/ae-solar-cme-132bds-730) - 6 differences, the largest is weight - [AE Solar AE CME-132 720 vs AE Solar CME-132BDS-730W](https://comparepv.com/compare/ae-solar-ae-cme-132-720/ae-solar-cme-132bds-730w) - 7 differences, the largest is weight - [AE Solar AE CME-132 720 vs AE Solar CME-132BDS-725](https://comparepv.com/compare/ae-solar-ae-cme-132-720/ae-solar-cme-132bds-725) - 3 differences, the largest is weight - [AE Solar AE CME-132 720 vs AE Solar CME-132-725W](https://comparepv.com/compare/ae-solar-ae-cme-132-720/ae-solar-cme-132-725w) - One difference: product warranty - [AE Solar AE CME-132 720 vs AE Solar CME-132BDS-725W](https://comparepv.com/compare/ae-solar-ae-cme-132-720/ae-solar-cme-132bds-725w) - 4 differences, the largest is weight - [AE Solar AE CME-132 720 vs AE Solar CME-132BDS-720](https://comparepv.com/compare/ae-solar-ae-cme-132-720/ae-solar-cme-132bds-720) - 3 differences, the largest is weight --- Source: https://comparepv.com/compare/ae-solar-ae-cme-132-720/ae-solar-ae440cmd-108bde 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.
