Questions about this pairing
Which panel is better: Mysolar USA MS680N-DHBG or Mysolar USA MS720N-HJTGB?
According to our database: Mysolar USA MS720N-HJTGB has higher module efficiency (23.17% vs 21.89%); Mysolar USA MS720N-HJTGB tolerates heat better (temp coeff -0.260%/°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 Mysolar USA MS680N-DHBG and Mysolar USA MS720N-HJTGB?
Mysolar USA MS680N-DHBG has a module efficiency of 21.89%, while Mysolar USA MS720N-HJTGB is 23.17%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does Mysolar USA MS680N-DHBG use vs Mysolar USA MS720N-HJTGB?
Mysolar USA MS680N-DHBG uses TOPCon cells; Mysolar USA 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 Mysolar USA MS680N-DHBG and Mysolar USA MS720N-HJTGB?
Mysolar USA MS680N-DHBG has a 30 years power warranty; Mysolar USA 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 Mysolar USA MS680N-DHBG and Mysolar USA MS720N-HJTGB bifacial panels?
Both Mysolar USA MS680N-DHBG and Mysolar USA 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.
Every figure here is from the manufacturers' own datasheets - a dash means the value is not published, never an estimate. The thirty-year projection and the temperature scenarios are calculations from those figures, and each states its assumption above.
