What it means on a roof
Thirty years of production
Declared annual degradation, with a 1.0% first-year loss assumed for both panels because at least one datasheet omits it, at 1,200 kWh/kWp a year
Same temp coeff. for both panels (-0.260 %/°C), so a warmer roof scales both curves by the same factor: the totals fall together and neither panel gains on the other.

Questions about this pairing
Which panel is better: Shinson Technology S720M66HT4BF or Shinson Technology S705M66HT4BF?
According to our database: Shinson Technology S720M66HT4BF has higher module efficiency (23.18% vs 22.70%). See the full spec comparison and 30-year energy simulation above for a complete picture.
What is the efficiency of Shinson Technology S720M66HT4BF and Shinson Technology S705M66HT4BF?
Shinson Technology S720M66HT4BF has a module efficiency of 23.18%, while Shinson Technology S705M66HT4BF is 22.70%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does Shinson Technology S720M66HT4BF use vs Shinson Technology S705M66HT4BF?
Shinson Technology S720M66HT4BF uses HJT cells; Shinson Technology S705M66HT4BF 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 Shinson Technology S720M66HT4BF and Shinson Technology S705M66HT4BF?
Shinson Technology S720M66HT4BF has a 30 years power warranty; Shinson Technology S705M66HT4BF 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 Shinson Technology S720M66HT4BF and Shinson Technology S705M66HT4BF bifacial panels?
Both Shinson Technology S720M66HT4BF and Shinson Technology S705M66HT4BF 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.
