According to our database: **Recom RCM-455-RDBNAA (Lynx series)** has higher module efficiency (**22.77%** vs **22.02%**). See the full spec comparison and 30-year energy simulation above for a complete picture. ### What is the efficiency of Recom RCM-440-RDBNAA (Lynx series) and Recom RCM-455-RDBNAA (Lynx series)? **Recom RCM-440-RDBNAA (Lynx series)** has a module efficiency of **22.02%**, while **Recom RCM-455-RDBNAA (Lynx series)** is **22.77%**. Higher efficiency means more electricity from the same roof area - useful when space is limited. ### What cell technology does Recom RCM-440-RDBNAA (Lynx series) use vs Recom RCM-455-RDBNAA (Lynx series)? **Recom RCM-440-RDBNAA (Lynx series)** uses **TOPCon** cells; **Recom RCM-455-RDBNAA (Lynx series)** 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 Recom RCM-440-RDBNAA (Lynx series) and Recom RCM-455-RDBNAA (Lynx series)? **Recom RCM-440-RDBNAA (Lynx series)** has a **30 years** power warranty; **Recom RCM-455-RDBNAA (Lynx series)** 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 Recom RCM-440-RDBNAA (Lynx series) and Recom RCM-455-RDBNAA (Lynx series) bifacial panels? Both **Recom RCM-440-RDBNAA (Lynx series)** and **Recom RCM-455-RDBNAA (Lynx series)** 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 - [Recom RCM-440-RDBNAA (Lynx series) vs Recom RCM-730-8DBNM](https://comparepv.com/compare/recom-rcm-440-rdbnaa-lynx-series/recom-rcm-730-8dbnm) - 13 differences, the largest is module efficiency - [Recom RCM-440-RDBNAA (Lynx series) vs Recom RCM-725-8DBNM](https://comparepv.com/compare/recom-rcm-440-rdbnaa-lynx-series/recom-rcm-725-8dbnm) - 13 differences, the largest is module efficiency - [Recom RCM-440-RDBNAA (Lynx series) vs Recom RCM-720-8DBNM](https://comparepv.com/compare/recom-rcm-440-rdbnaa-lynx-series/recom-rcm-720-8dbnm) - 13 differences, the largest is module efficiency - [Recom RCM-440-RDBNAA (Lynx series) vs Recom RCM-715-8DBNM](https://comparepv.com/compare/recom-rcm-440-rdbnaa-lynx-series/recom-rcm-715-8dbnm) - 13 differences, the largest is module efficiency - [Recom RCM-440-RDBNAA (Lynx series) vs Recom RCM-715-8NM](https://comparepv.com/compare/recom-rcm-440-rdbnaa-lynx-series/recom-rcm-715-8nm) - 13 differences, the largest is module efficiency - [Recom RCM-440-RDBNAA (Lynx series) vs Recom RCM-710-8DBNM](https://comparepv.com/compare/recom-rcm-440-rdbnaa-lynx-series/recom-rcm-710-8dbnm) - 13 differences, the largest is module efficiency --- Source: https://comparepv.com/compare/recom-rcm-440-rdbnaa-lynx-series/recom-rcm-455-rdbnaa-lynx-series 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.
