According to our database: **AE Solar AE CME-132-720** has higher module efficiency (**23.21%** vs **21.80%**). See the full spec comparison and 30-year energy simulation above for a complete picture. ### What is the efficiency of AE Solar AE CMD-108BDS-425 and AE Solar AE CME-132-720? **AE Solar AE CMD-108BDS-425** has a module efficiency of **21.80%**, 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 AE Solar AE CMD-108BDS-425 use vs AE Solar AE CME-132-720? **AE Solar AE CMD-108BDS-425** uses **TOPCon** 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 AE Solar AE CMD-108BDS-425 and AE Solar AE CME-132-720? **AE Solar AE CMD-108BDS-425** 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 AE Solar AE CMD-108BDS-425 and AE Solar AE CME-132-720 bifacial panels? **AE Solar AE CMD-108BDS-425** 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 CMD-108BDS-425 vs AE Solar CMD-108BDS-440W](https://comparepv.com/compare/ae-solar-ae-cmd-108bds-425/ae-solar-cmd-108bds-440w) - 3 differences, the largest is module efficiency - [AE Solar AE CMD-108BDS-425 vs AE Solar AE CMD-108BDS-440](https://comparepv.com/compare/ae-solar-ae-cmd-108bds-425/ae-solar-ae-cmd-108bds-440) - 3 differences, the largest is module efficiency - [AE Solar AE CMD-108BDS-425 vs AE Solar AE440CMD-108BDE](https://comparepv.com/compare/ae-solar-ae-cmd-108bds-425/ae-solar-ae440cmd-108bde) - 6 differences, the largest is module efficiency - [AE Solar AE CMD-108BDS-425 vs AE Solar AExxxCMD-108BDE](https://comparepv.com/compare/ae-solar-ae-cmd-108bds-425/ae-solar-aexxxcmd-108bde) - 6 differences, the largest is module efficiency - [AE Solar AE CMD-108BDS-425 vs AE Solar CMD-108BDS-435W](https://comparepv.com/compare/ae-solar-ae-cmd-108bds-425/ae-solar-cmd-108bds-435w) - 3 differences, the largest is module efficiency - [AE Solar AE CMD-108BDS-425 vs AE Solar CMD-108BDE-435W](https://comparepv.com/compare/ae-solar-ae-cmd-108bds-425/ae-solar-cmd-108bde-435w) - 3 differences, the largest is module efficiency --- Source: https://comparepv.com/compare/ae-solar-ae-cmd-108bds-425/ae-solar-ae-cme-132-720-1 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.
