According to our database: **AE Solar AE ICME-132BDS-655** has higher module efficiency (**24.25%** vs **23.88%**). See the full spec comparison and 30-year energy simulation above for a complete picture. ### What is the efficiency of AE Solar AE ICME-132BDS-655 and AE Solar ICME-132BDS-645? **AE Solar AE ICME-132BDS-655** has a module efficiency of **24.25%**, while **AE Solar ICME-132BDS-645** is **23.88%**. Higher efficiency means more electricity from the same roof area - useful when space is limited. ### What cell technology does AE Solar AE ICME-132BDS-655 use vs AE Solar ICME-132BDS-645? **AE Solar AE ICME-132BDS-655** uses **Back Contact** cells; **AE Solar ICME-132BDS-645** uses **Back Contact**. 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 ICME-132BDS-655 and AE Solar ICME-132BDS-645? **AE Solar AE ICME-132BDS-655** has a **30 years** power warranty; **AE Solar ICME-132BDS-645** 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 ICME-132BDS-655 and AE Solar ICME-132BDS-645 bifacial panels? Both **AE Solar AE ICME-132BDS-655** and **AE Solar ICME-132BDS-645** 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 AE ICME-132BDS-655 vs AE Solar ICME-132BDS-660](https://comparepv.com/compare/ae-solar-ae-icme-132bds-655/ae-solar-icme-132bds-660) - The same specification on paper - [AE Solar AE ICME-132BDS-655 vs AE Solar AE ICME-132BDS-660](https://comparepv.com/compare/ae-solar-ae-icme-132bds-655/ae-solar-ae-icme-132bds-660) - The same specification on paper - [AE Solar AE ICME-132BDS-655 vs AE Solar ICME-132BDS-655](https://comparepv.com/compare/ae-solar-ae-icme-132bds-655/ae-solar-icme-132bds-655) - The same specification on paper - [AE Solar AE ICME-132BDS-655 vs AE Solar ICME-132BDS-650](https://comparepv.com/compare/ae-solar-ae-icme-132bds-655/ae-solar-icme-132bds-650) - The same specification on paper - [AE Solar AE ICME-132BDS-655 vs AE Solar AE ICME-132BDS-650](https://comparepv.com/compare/ae-solar-ae-icme-132bds-655/ae-solar-ae-icme-132bds-650) - The same specification on paper - [AE Solar AE ICME-132BDS-655 vs AE Solar AE ICME-132BDS-645](https://comparepv.com/compare/ae-solar-ae-icme-132bds-655/ae-solar-ae-icme-132bds-645) - 3 differences, the largest is module efficiency --- Source: https://comparepv.com/compare/ae-solar-ae-icme-132bds-655/ae-solar-icme-132bds-645 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.
