Questions about this pairing
Which panel is better: Mysolar USA MS700N-HJTGB or Mysolar USA MS690N-DHBG?
According to our database: Mysolar USA MS700N-HJTGB has higher module efficiency (22.53% vs 22.21%); Mysolar USA MS700N-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 MS700N-HJTGB and Mysolar USA MS690N-DHBG?
Mysolar USA MS700N-HJTGB has a module efficiency of 22.53%, while Mysolar USA MS690N-DHBG is 22.21%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does Mysolar USA MS700N-HJTGB use vs Mysolar USA MS690N-DHBG?
Mysolar USA MS700N-HJTGB uses HJT cells; Mysolar USA MS690N-DHBG 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 Mysolar USA MS700N-HJTGB and Mysolar USA MS690N-DHBG?
Mysolar USA MS700N-HJTGB has a 30 years power warranty; Mysolar USA MS690N-DHBG 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 MS700N-HJTGB and Mysolar USA MS690N-DHBG bifacial panels?
Both Mysolar USA MS700N-HJTGB and Mysolar USA MS690N-DHBG 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.
