What it means on a roof

Thirty years of production
Each panel's own declared degradation curve, at 1,200 kWh/kWp a year
Same temp coeff. for both panels (-0.350 %/°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: Emmvee E550HCBG144 or Emmvee E495HCBG132?
According to our database: Emmvee E550HCBG144 has higher module efficiency (21.29% vs 20.82%). See the full spec comparison and 30-year energy simulation above for a complete picture.
What is the efficiency of Emmvee E550HCBG144 and Emmvee E495HCBG132?
Emmvee E550HCBG144 has a module efficiency of 21.29%, while Emmvee E495HCBG132 is 20.82%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does Emmvee E550HCBG144 use vs Emmvee E495HCBG132?
Emmvee E550HCBG144 uses PERC cells; Emmvee E495HCBG132 uses PERC. 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 Emmvee E550HCBG144 and Emmvee E495HCBG132?
Emmvee E550HCBG144 has a 30 years power warranty; Emmvee E495HCBG132 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 Emmvee E550HCBG144 and Emmvee E495HCBG132 bifacial panels?
Both Emmvee E550HCBG144 and Emmvee E495HCBG132 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.

Every figure here is from the manufacturers' own datasheets - a dash means the value is not published, never an estimate. The thirty-year projection and the temperature scenarios are calculations from those figures, and each states its assumption above.
