Recom RCM-440-RDBNAA (Lynx series) vs Recom RCM-455-RDBNAA (Lynx series)

Q: Which panel is better: Recom RCM-440-RDBNAA (Lynx series) or Recom RCM-455-RDBNAA (Lynx series)?

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.

Q: 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.

Q: 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.

Q: 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.

Q: 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.
