Emmvee E550HCBG144 vs Emmvee E490HCBG132

Q: Which panel is better: Emmvee E550HCBG144 or Emmvee E490HCBG132?

According to our database: Emmvee E550HCBG144 has higher module efficiency (21.29% vs 20.61%). See the full spec comparison and 30-year energy simulation above for a complete picture.

Q: What is the efficiency of Emmvee E550HCBG144 and Emmvee E490HCBG132?

Emmvee E550HCBG144 has a module efficiency of 21.29%, while Emmvee E490HCBG132 is 20.61%. Higher efficiency means more electricity from the same roof area - useful when space is limited.

Q: What cell technology does Emmvee E550HCBG144 use vs Emmvee E490HCBG132?

Emmvee E550HCBG144 uses PERC cells; Emmvee E490HCBG132 uses PERC. 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 E550HCBG144 and Emmvee E490HCBG132?

Emmvee E550HCBG144 has a 30 years power warranty; Emmvee E490HCBG132 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 E550HCBG144 and Emmvee E490HCBG132 bifacial panels?

Both Emmvee E550HCBG144 and Emmvee E490HCBG132 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.
