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 (-0.310 %/°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: Huasun RS705S9-132GANT or Huasun RS715S89-132GANT?
According to our database: Huasun RS715S89-132GANT has higher module efficiency (23.02% vs 22.70%). See the full spec comparison and 30-year energy simulation above for a complete picture.
What is the efficiency of Huasun RS705S9-132GANT and Huasun RS715S89-132GANT?
Huasun RS705S9-132GANT has a module efficiency of 22.70%, while Huasun RS715S89-132GANT is 23.02%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does Huasun RS705S9-132GANT use vs Huasun RS715S89-132GANT?
Huasun RS705S9-132GANT uses TOPCon cells; Huasun RS715S89-132GANT 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 Huasun RS705S9-132GANT and Huasun RS715S89-132GANT?
Huasun RS705S9-132GANT has a 30 years power warranty; Huasun RS715S89-132GANT 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 Huasun RS705S9-132GANT and Huasun RS715S89-132GANT bifacial panels?
Both Huasun RS705S9-132GANT and Huasun RS715S89-132GANT 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.
