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 Sharp GSD8K66H-740WT?
According to our database: Sharp GSD8K66H-740WT has higher module efficiency (23.82% vs 23.18%). See the full spec comparison and 30-year energy simulation above for a complete picture.
What is the efficiency of Shinson Technology S720M66HT4BF and Sharp GSD8K66H-740WT?
Shinson Technology S720M66HT4BF has a module efficiency of 23.18%, while Sharp GSD8K66H-740WT is 23.82%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does Shinson Technology S720M66HT4BF use vs Sharp GSD8K66H-740WT?
Shinson Technology S720M66HT4BF uses HJT cells; Sharp GSD8K66H-740WT 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 Sharp GSD8K66H-740WT?
Shinson Technology S720M66HT4BF has a 30 years power warranty; Sharp GSD8K66H-740WT 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 Sharp GSD8K66H-740WT bifacial panels?
Both Shinson Technology S720M66HT4BF and Sharp GSD8K66H-740WT 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.
