Questions about this pairing
Which panel is better: Recom RCM-455-RDBNAA (Lynx series) or Recom RCM-720-8DBNM?
According to our database: Recom RCM-720-8DBNM has higher module efficiency (23.20% vs 22.77%); Recom RCM-455-RDBNAA (Lynx series) tolerates heat better (temp coeff -0.280%/°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 Recom RCM-455-RDBNAA (Lynx series) and Recom RCM-720-8DBNM?
Recom RCM-455-RDBNAA (Lynx series) has a module efficiency of 22.77%, while Recom RCM-720-8DBNM is 23.20%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does Recom RCM-455-RDBNAA (Lynx series) use vs Recom RCM-720-8DBNM?
Recom RCM-455-RDBNAA (Lynx series) uses TOPCon cells; Recom RCM-720-8DBNM 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-455-RDBNAA (Lynx series) and Recom RCM-720-8DBNM?
Recom RCM-455-RDBNAA (Lynx series) has a 30 years power warranty; Recom RCM-720-8DBNM 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-455-RDBNAA (Lynx series) and Recom RCM-720-8DBNM bifacial panels?
Both Recom RCM-455-RDBNAA (Lynx series) and Recom RCM-720-8DBNM 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.
