Bisol BGO 570 vs Bisol BDO 450

Q: Which panel is better: Bisol BGO 570 or Bisol BDO 450?

According to our database: Bisol BGO 570 has higher module efficiency (23.10% vs 22.50%). See the full spec comparison and 30-year energy simulation above for a complete picture.

Q: What is the efficiency of Bisol BGO 570 and Bisol BDO 450?

Bisol BGO 570 has a module efficiency of 23.10%, while Bisol BDO 450 is 22.50%. Higher efficiency means more electricity from the same roof area - useful when space is limited.

Q: What cell technology does Bisol BGO 570 use vs Bisol BDO 450?

Bisol BGO 570 uses TOPCon cells; Bisol BDO 450 uses PERC. Modern n-type technologies (TOPCon, HJT, BC) typically deliver higher efficiency and lower degradation compared to older PERC (p-type) cells.

Q: What is the warranty on Bisol BGO 570 and Bisol BDO 450?

Bisol BGO 570 has a 30 years power warranty; Bisol BDO 450 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.

What it means on a roof

Thirty years of production

Each panel's own declared degradation curve, at 1,200 kWh/kWp a year

Cell temperature

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.
