Questions about this pairing
Which panel is better: Huasun RS705S9-132GANT or Huasun HSN-210-B132DS730?
According to our database: Huasun HSN-210-B132DS730 has higher module efficiency (23.50% vs 22.70%); Huasun HSN-210-B132DS730 tolerates heat better (temp coeff -0.240%/°C vs -0.310%/°C). 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 HSN-210-B132DS730?
Huasun RS705S9-132GANT has a module efficiency of 22.70%, while Huasun HSN-210-B132DS730 is 23.50%. 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 HSN-210-B132DS730?
Huasun RS705S9-132GANT uses TOPCon cells; Huasun HSN-210-B132DS730 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 HSN-210-B132DS730?
Huasun RS705S9-132GANT has a 30 years power warranty; Huasun HSN-210-B132DS730 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 HSN-210-B132DS730 bifacial panels?
Both Huasun RS705S9-132GANT and Huasun HSN-210-B132DS730 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.
