Questions about this pairing
Which panel is better: Mission Solar MST12R615HN3G or Mission Solar MSI10-585HN4G?
According to our database: Mission Solar MST12R615HN3G has higher module efficiency (22.80% vs 22.67%); Mission Solar MST12R615HN3G tolerates heat better (temp coeff -0.290%/°C vs -0.298%/°C). See the full spec comparison and 30-year energy simulation above for a complete picture.
What is the efficiency of Mission Solar MST12R615HN3G and Mission Solar MSI10-585HN4G?
Mission Solar MST12R615HN3G has a module efficiency of 22.80%, while Mission Solar MSI10-585HN4G is 22.67%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does Mission Solar MST12R615HN3G use vs Mission Solar MSI10-585HN4G?
Mission Solar MST12R615HN3G uses N-type cells; Mission Solar MSI10-585HN4G 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 Mission Solar MST12R615HN3G and Mission Solar MSI10-585HN4G?
Mission Solar MST12R615HN3G has a 30 years power warranty; Mission Solar MSI10-585HN4G 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 Mission Solar MST12R615HN3G and Mission Solar MSI10-585HN4G bifacial panels?
Both Mission Solar MST12R615HN3G and Mission Solar MSI10-585HN4G 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.
