Questions about this pairing
Which panel is better: MY Solar MS740N-HJTGB or Shinson Technology S720M66HT4BF?
According to our database: MY Solar MS740N-HJTGB has higher module efficiency (23.82% vs 23.18%); MY Solar MS740N-HJTGB tolerates heat better (temp coeff -0.240%/°C vs -0.260%/°C). See the full spec comparison and 30-year energy simulation above for a complete picture.
What is the efficiency of MY Solar MS740N-HJTGB and Shinson Technology S720M66HT4BF?
MY Solar MS740N-HJTGB has a module efficiency of 23.82%, while Shinson Technology S720M66HT4BF is 23.18%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does MY Solar MS740N-HJTGB use vs Shinson Technology S720M66HT4BF?
MY Solar MS740N-HJTGB uses HJT cells; Shinson Technology S720M66HT4BF 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 MY Solar MS740N-HJTGB and Shinson Technology S720M66HT4BF?
MY Solar MS740N-HJTGB has a 30 years power warranty; Shinson Technology S720M66HT4BF 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 MY Solar MS740N-HJTGB and Shinson Technology S720M66HT4BF bifacial panels?
Both MY Solar MS740N-HJTGB and Shinson Technology S720M66HT4BF 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.
