According to our database: **AE Solar AE440CMD-108BDE** has higher module efficiency (**22.57%** vs **22.10%**); **REC REC460AA PURE-RX** tolerates heat better (temp coeff **-0.240%/°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 AE440CMD-108BDE and REC REC460AA PURE-RX? **AE Solar AE440CMD-108BDE** has a module efficiency of **22.57%**, while **REC REC460AA PURE-RX** is **22.10%**. Higher efficiency means more electricity from the same roof area - useful when space is limited. ### What cell technology does AE Solar AE440CMD-108BDE use vs REC REC460AA PURE-RX? **AE Solar AE440CMD-108BDE** uses **TOPCon** cells; **REC REC460AA PURE-RX** 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 AE440CMD-108BDE and REC REC460AA PURE-RX? **AE Solar AE440CMD-108BDE** has a **30 years** power warranty; **REC REC460AA PURE-RX** has a **25 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 AE440CMD-108BDE and REC REC460AA PURE-RX bifacial panels? Both **AE Solar AE440CMD-108BDE** and **REC REC460AA PURE-RX** 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 AE440CMD-108BDE vs AE Solar CME-132BDS-730](https://comparepv.com/compare/ae-solar-ae440cmd-108bde/ae-solar-cme-132bds-730) - 13 differences, the largest is module efficiency - [AE Solar AE440CMD-108BDE vs AE Solar CME-132BDS-730W](https://comparepv.com/compare/ae-solar-ae440cmd-108bde/ae-solar-cme-132bds-730w) - 12 differences, the largest is module efficiency - [AE Solar AE440CMD-108BDE vs AE Solar CME-132BDS-725](https://comparepv.com/compare/ae-solar-ae440cmd-108bde/ae-solar-cme-132bds-725) - 13 differences, the largest is module efficiency - [AE Solar AE440CMD-108BDE vs AE Solar CME-132-725W](https://comparepv.com/compare/ae-solar-ae440cmd-108bde/ae-solar-cme-132-725w) - 12 differences, the largest is module efficiency - [AE Solar AE440CMD-108BDE vs AE Solar CME-132BDS-725W](https://comparepv.com/compare/ae-solar-ae440cmd-108bde/ae-solar-cme-132bds-725w) - 12 differences, the largest is module efficiency - [AE Solar AE440CMD-108BDE vs AE Solar AE CME-132 720](https://comparepv.com/compare/ae-solar-ae440cmd-108bde/ae-solar-ae-cme-132-720) - 13 differences, the largest is module efficiency --- Source: https://comparepv.com/compare/ae-solar-ae440cmd-108bde/rec-rec460aa-pure-rx 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.
