The verdict
Identical on every published parameter
All 19 comparable parameters agree. Two records this alike are usually one panel sold under two names, or two bins of the same production line - decide on price and on who you would rather buy from.

What it means on a roof
Thirty years of production
Declared annual degradation, with a 1.0% first-year loss assumed for both panels because at least one datasheet omits it, 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-21-610 or Waaree BiN-21-615?
According to our database: Waaree BiN-21-615 has higher module efficiency (22.77% vs 22.58%). See the full spec comparison and 30-year energy simulation above for a complete picture.
What is the efficiency of Waaree BiN-21-610 and Waaree BiN-21-615?
Waaree BiN-21-610 has a module efficiency of 22.58%, while Waaree BiN-21-615 is 22.77%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does Waaree BiN-21-610 use vs Waaree BiN-21-615?
Waaree BiN-21-610 uses TOPCon cells; Waaree BiN-21-615 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-21-610 and Waaree BiN-21-615?
Waaree BiN-21-610 has a 30 years power warranty; Waaree BiN-21-615 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-21-610 and Waaree BiN-21-615 bifacial panels?
Both Waaree BiN-21-610 and Waaree BiN-21-615 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.
