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: Bisol BGO 560 or Bisol BDO 440?
According to our database: Bisol BGO 560 has higher module efficiency (22.70% vs 22.00%). See the full spec comparison and 30-year energy simulation above for a complete picture.
What is the efficiency of Bisol BGO 560 and Bisol BDO 440?
Bisol BGO 560 has a module efficiency of 22.70%, while Bisol BDO 440 is 22.00%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does Bisol BGO 560 use vs Bisol BDO 440?
Bisol BGO 560 uses TOPCon cells; Bisol BDO 440 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 Bisol BGO 560 and Bisol BDO 440?
Bisol BGO 560 has a 30 years power warranty; Bisol BDO 440 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.
