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-08-585 or Waaree BiN-08-575?
According to our database: Waaree BiN-08-585 has higher module efficiency (22.65% vs 22.26%). See the full spec comparison and 30-year energy simulation above for a complete picture.
What is the efficiency of Waaree BiN-08-585 and Waaree BiN-08-575?
Waaree BiN-08-585 has a module efficiency of 22.65%, while Waaree BiN-08-575 is 22.26%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does Waaree BiN-08-585 use vs Waaree BiN-08-575?
Waaree BiN-08-585 uses N-type cells; Waaree BiN-08-575 uses N-type. 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-08-585 and Waaree BiN-08-575?
Waaree BiN-08-585 has a 30 years power warranty; Waaree BiN-08-575 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-08-585 and Waaree BiN-08-575 bifacial panels?
Both Waaree BiN-08-585 and Waaree BiN-08-575 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.
