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 (-0.290 %/°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 E720HCBG132-T or Emmvee E635HCBG132-T?
According to our database: Emmvee E635HCBG132-T has higher module efficiency (23.51% vs 23.18%). See the full spec comparison and 30-year energy simulation above for a complete picture.
What is the efficiency of Emmvee E720HCBG132-T and Emmvee E635HCBG132-T?
Emmvee E720HCBG132-T has a module efficiency of 23.18%, while Emmvee E635HCBG132-T is 23.51%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does Emmvee E720HCBG132-T use vs Emmvee E635HCBG132-T?
Emmvee E720HCBG132-T uses TOPCon cells; Emmvee E635HCBG132-T uses TOPCon. 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 E720HCBG132-T and Emmvee E635HCBG132-T?
Emmvee E720HCBG132-T has a 30 years power warranty; Emmvee E635HCBG132-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.
Are Emmvee E720HCBG132-T and Emmvee E635HCBG132-T bifacial panels?
Both Emmvee E720HCBG132-T and Emmvee E635HCBG132-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.
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.
