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 (-0.300 %/°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: Waaree BiN-08-545 or Waaree BiN-08-550?
According to our database: Waaree BiN-08-550 has higher module efficiency (21.28% vs 21.09%). See the full spec comparison and 30-year energy simulation above for a complete picture.
What is the efficiency of Waaree BiN-08-545 and Waaree BiN-08-550?
Waaree BiN-08-545 has a module efficiency of 21.09%, while Waaree BiN-08-550 is 21.28%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does Waaree BiN-08-545 use vs Waaree BiN-08-550?
Waaree BiN-08-545 uses TOPCon cells; Waaree BiN-08-550 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 Waaree BiN-08-545 and Waaree BiN-08-550?
Waaree BiN-08-545 has a 30 years power warranty; Waaree BiN-08-550 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 Waaree BiN-08-545 and Waaree BiN-08-550 bifacial panels?
Both Waaree BiN-08-545 and Waaree BiN-08-550 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.
