Emmvee E595HCBT144-T vs Emmvee E590HCBT144-T

Q: Which panel is better: Emmvee E595HCBT144-T or Emmvee E590HCBT144-T?

According to our database: Emmvee E595HCBT144-T has higher module efficiency (23.03% vs 22.84%). See the full spec comparison and 30-year energy simulation above for a complete picture.

Q: What is the efficiency of Emmvee E595HCBT144-T and Emmvee E590HCBT144-T?

Emmvee E595HCBT144-T has a module efficiency of 23.03%, while Emmvee E590HCBT144-T is 22.84%. Higher efficiency means more electricity from the same roof area - useful when space is limited.

Q: What cell technology does Emmvee E595HCBT144-T use vs Emmvee E590HCBT144-T?

Emmvee E595HCBT144-T uses TOPCon cells; Emmvee E590HCBT144-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 E595HCBT144-T and Emmvee E590HCBT144-T?

Emmvee E595HCBT144-T has a 25 years power warranty; Emmvee E590HCBT144-T has a 25 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 E595HCBT144-T and Emmvee E590HCBT144-T bifacial panels?

Both Emmvee E595HCBT144-T and Emmvee E590HCBT144-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.

The verdict

Identical on every published parameter

All 19 comparable parameters agree. Two records this alike are usually one panel sold under two names, or two bins of the same production line - decide on price and on who you would rather buy from.

Each panel's own declared degradation curve, at 1,200 kWh/kWp a year

Cell temperature

Same temp coeff. for both panels (-0.290 %/°C), so a warmer roof scales both curves by the same factor: the totals fall together and neither panel gains on the other.
