Q: Which panel is better: Emmvee E705HCBG132-T or Emmvee E720HCBG132-T?

According to our database: Emmvee E720HCBG132-T has higher module efficiency (23.18% vs 22.70%). See the full spec comparison and 30-year energy simulation above for a complete picture.

Q: What is the efficiency of Emmvee E705HCBG132-T and Emmvee E720HCBG132-T?

Emmvee E705HCBG132-T has a module efficiency of 22.70%, while Emmvee E720HCBG132-T is 23.18%. Higher efficiency means more electricity from the same roof area - useful when space is limited.

Q: What cell technology does Emmvee E705HCBG132-T use vs Emmvee E720HCBG132-T?

Emmvee E705HCBG132-T uses TOPCon cells; Emmvee E720HCBG132-T uses TOPCon. Modern n-type technologies (TOPCon, HJT, BC) typically deliver higher efficiency and lower degradation compared to older PERC (p-type) cells.

Q: What is the warranty on Emmvee E705HCBG132-T and Emmvee E720HCBG132-T?

Emmvee E705HCBG132-T has a 30 years power warranty; Emmvee E720HCBG132-T 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.

Q: Are Emmvee E705HCBG132-T and Emmvee E720HCBG132-T bifacial panels?

Both Emmvee E705HCBG132-T and Emmvee E720HCBG132-T 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.
