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 BBO 500 or Bisol BDO 460?
According to our database: Bisol BDO 460 has higher module efficiency (23.00% vs 22.30%). See the full spec comparison and 30-year energy simulation above for a complete picture.
What is the efficiency of Bisol BBO 500 and Bisol BDO 460?
Bisol BBO 500 has a module efficiency of 22.30%, while Bisol BDO 460 is 23.00%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does Bisol BBO 500 use vs Bisol BDO 460?
Bisol BBO 500 uses PERC cells; Bisol BDO 460 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 Bisol BBO 500 and Bisol BDO 460?
Bisol BBO 500 has a 30 years power warranty; Bisol BDO 460 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.
