Questions about this pairing
Which panel is better: Recom RCM-715-8NM or Recom RCM-440-RDBNAA (Lynx series)?
According to our database: Recom RCM-715-8NM has higher module efficiency (23.02% vs 22.02%); Recom RCM-440-RDBNAA (Lynx series) tolerates heat better (temp coeff -0.280%/°C vs -0.300%/°C). See the full spec comparison and 30-year energy simulation above for a complete picture.
What is the efficiency of Recom RCM-715-8NM and Recom RCM-440-RDBNAA (Lynx series)?
Recom RCM-715-8NM has a module efficiency of 23.02%, while Recom RCM-440-RDBNAA (Lynx series) is 22.02%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does Recom RCM-715-8NM use vs Recom RCM-440-RDBNAA (Lynx series)?
Recom RCM-715-8NM uses TOPCon cells; Recom RCM-440-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-715-8NM and Recom RCM-440-RDBNAA (Lynx series)?
Recom RCM-715-8NM has a 30 years power warranty; Recom RCM-440-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-715-8NM and Recom RCM-440-RDBNAA (Lynx series) bifacial panels?
Recom RCM-440-RDBNAA (Lynx series) is bifacial (captures light from both faces); Recom RCM-715-8NM is monofacial. Bifacial panels work best on ground mounts or raised structures with a light-coloured surface underneath.
