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 (-0.240 %/°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 BiH-11-705 or Waaree BiH-11-730?
According to our database: Waaree BiH-11-730 has higher module efficiency (23.50% vs 22.70%). See the full spec comparison and 30-year energy simulation above for a complete picture.
What is the efficiency of Waaree BiH-11-705 and Waaree BiH-11-730?
Waaree BiH-11-705 has a module efficiency of 22.70%, while Waaree BiH-11-730 is 23.50%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does Waaree BiH-11-705 use vs Waaree BiH-11-730?
Waaree BiH-11-705 uses HJT cells; Waaree BiH-11-730 uses HJT. 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 BiH-11-705 and Waaree BiH-11-730?
Waaree BiH-11-705 has a 30 years power warranty; Waaree BiH-11-730 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 BiH-11-705 and Waaree BiH-11-730 bifacial panels?
Both Waaree BiH-11-705 and Waaree BiH-11-730 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.
