According to our database: **AE Solar AExxxCMD-108BDE** has higher module efficiency (**22.57%** vs **22.31%**). See the full spec comparison and 30-year energy simulation above for a complete picture. ### What is the efficiency of AE Solar AExxxCMD-108BDE and AE Solar CMD-108BDS-435W? **AE Solar AExxxCMD-108BDE** has a module efficiency of **22.57%**, while **AE Solar CMD-108BDS-**435 W**** is **22.31%**. Higher efficiency means more electricity from the same roof area - useful when space is limited. ### What cell technology does AE Solar AExxxCMD-108BDE use vs AE Solar CMD-108BDS-435W? **AE Solar AExxxCMD-108BDE** uses **TOPCon** cells; **AE Solar CMD-108BDS-**435 W**** 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 AExxxCMD-108BDE and AE Solar CMD-108BDS-435W? **AE Solar AExxxCMD-108BDE** has a **30 years** power warranty; **AE Solar CMD-108BDS-**435 W**** 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 AExxxCMD-108BDE and AE Solar CMD-108BDS-435W bifacial panels? Both **AE Solar AExxxCMD-108BDE** and **AE Solar CMD-108BDS-**435 W**** 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 AExxxCMD-108BDE vs AE Solar CME-132BDS-730](https://comparepv.com/compare/ae-solar-aexxxcmd-108bde/ae-solar-cme-132bds-730) - 12 differences, the largest is module efficiency - [AE Solar AExxxCMD-108BDE vs AE Solar CME-132BDS-730W](https://comparepv.com/compare/ae-solar-aexxxcmd-108bde/ae-solar-cme-132bds-730w) - 11 differences, the largest is module efficiency - [AE Solar AExxxCMD-108BDE vs AE Solar CME-132BDS-725](https://comparepv.com/compare/ae-solar-aexxxcmd-108bde/ae-solar-cme-132bds-725) - 13 differences, the largest is module efficiency - [AE Solar AExxxCMD-108BDE vs AE Solar CME-132-725W](https://comparepv.com/compare/ae-solar-aexxxcmd-108bde/ae-solar-cme-132-725w) - 13 differences, the largest is module efficiency - [AE Solar AExxxCMD-108BDE vs AE Solar CME-132BDS-725W](https://comparepv.com/compare/ae-solar-aexxxcmd-108bde/ae-solar-cme-132bds-725w) - 12 differences, the largest is module efficiency - [AE Solar AExxxCMD-108BDE vs AE Solar AE CME-132 720](https://comparepv.com/compare/ae-solar-aexxxcmd-108bde/ae-solar-ae-cme-132-720) - 14 differences, the largest is module efficiency --- Source: https://comparepv.com/compare/ae-solar-aexxxcmd-108bde/ae-solar-cmd-108bds-435w 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.
