Recom RCM-720-8DBNM vs Recom RCM-705-8DBNM

Q: Which panel is better: Recom RCM-720-8DBNM or Recom RCM-705-8DBNM?

According to our database: Recom RCM-720-8DBNM has higher module efficiency (23.20% vs 22.70%). See the full spec comparison and 30-year energy simulation above for a complete picture.

Q: What is the efficiency of Recom RCM-720-8DBNM and Recom RCM-705-8DBNM?

Recom RCM-720-8DBNM has a module efficiency of 23.20%, while Recom RCM-705-8DBNM is 22.70%. Higher efficiency means more electricity from the same roof area - useful when space is limited.

Q: What cell technology does Recom RCM-720-8DBNM use vs Recom RCM-705-8DBNM?

Recom RCM-720-8DBNM uses TOPCon cells; Recom RCM-705-8DBNM 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-720-8DBNM and Recom RCM-705-8DBNM?

Recom RCM-720-8DBNM has a 30 years power warranty; Recom RCM-705-8DBNM 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.

Q: Are Recom RCM-720-8DBNM and Recom RCM-705-8DBNM bifacial panels?

Both Recom RCM-720-8DBNM and Recom RCM-705-8DBNM 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.
