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-08-570 or Waaree BiN-08-590?
According to our database: Waaree BiN-08-590 has higher module efficiency (22.84% vs 22.07%). See the full spec comparison and 30-year energy simulation above for a complete picture.
What is the efficiency of Waaree BiN-08-570 and Waaree BiN-08-590?
Waaree BiN-08-570 has a module efficiency of 22.07%, while Waaree BiN-08-590 is 22.84%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does Waaree BiN-08-570 use vs Waaree BiN-08-590?
Waaree BiN-08-570 uses N-type cells; Waaree BiN-08-590 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-08-570 and Waaree BiN-08-590?
Waaree BiN-08-570 has a 30 years power warranty; Waaree BiN-08-590 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-08-570 and Waaree BiN-08-590 bifacial panels?
Both Waaree BiN-08-570 and Waaree BiN-08-590 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.
