Questions about this pairing
Which panel is better: Shinson Technology S720M66HT4BF or Recom RCM-730-8DBNM?
According to our database: Recom RCM-730-8DBNM has higher module efficiency (23.50% vs 23.18%); Shinson Technology S720M66HT4BF tolerates heat better (temp coeff -0.260%/°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 Shinson Technology S720M66HT4BF and Recom RCM-730-8DBNM?
Shinson Technology S720M66HT4BF has a module efficiency of 23.18%, while Recom RCM-730-8DBNM is 23.50%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does Shinson Technology S720M66HT4BF use vs Recom RCM-730-8DBNM?
Shinson Technology S720M66HT4BF uses HJT cells; Recom RCM-730-8DBNM 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 Shinson Technology S720M66HT4BF and Recom RCM-730-8DBNM?
Shinson Technology S720M66HT4BF has a 30 years power warranty; Recom RCM-730-8DBNM 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 Shinson Technology S720M66HT4BF and Recom RCM-730-8DBNM bifacial panels?
Both Shinson Technology S720M66HT4BF and Recom RCM-730-8DBNM 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.
