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 E535HCM144-B or Emmvee E530HCBG144?
According to our database: Emmvee E535HCM144-B has higher module efficiency (20.71% vs 20.52%). See the full spec comparison and 30-year energy simulation above for a complete picture.
What is the efficiency of Emmvee E535HCM144-B and Emmvee E530HCBG144?
Emmvee E535HCM144-B has a module efficiency of 20.71%, while Emmvee E530HCBG144 is 20.52%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does Emmvee E535HCM144-B use vs Emmvee E530HCBG144?
Emmvee E535HCM144-B uses PERC cells; Emmvee E530HCBG144 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 E535HCM144-B and Emmvee E530HCBG144?
Emmvee E535HCM144-B has a 25 years power warranty; Emmvee E530HCBG144 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 E535HCM144-B and Emmvee E530HCBG144 bifacial panels?
Emmvee E530HCBG144 is bifacial (captures light from both faces); Emmvee E535HCM144-B is monofacial. Bifacial panels work best on ground mounts or raised structures with a light-coloured surface underneath.

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.
