Questions about this pairing
Which panel is better: Recom RCM-730-8DBNM or MY Solar MS720N-HJTGB?
According to our database: Recom RCM-730-8DBNM has higher module efficiency (23.50% vs 23.17%); MY Solar MS720N-HJTGB 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 Recom RCM-730-8DBNM and MY Solar MS720N-HJTGB?
Recom RCM-730-8DBNM has a module efficiency of 23.50%, while MY Solar MS720N-HJTGB is 23.17%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does Recom RCM-730-8DBNM use vs MY Solar MS720N-HJTGB?
Recom RCM-730-8DBNM uses TOPCon cells; MY Solar MS720N-HJTGB uses HJT. 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-730-8DBNM and MY Solar MS720N-HJTGB?
Recom RCM-730-8DBNM has a 30 years power warranty; MY Solar MS720N-HJTGB 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-730-8DBNM and MY Solar MS720N-HJTGB bifacial panels?
Both Recom RCM-730-8DBNM and MY Solar MS720N-HJTGB 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.
