Questions about this pairing
Which panel is better: Waaree Bi-68-665 or Waaree BiH-11-705?
According to our database: Waaree BiH-11-705 has higher module efficiency (22.70% vs 21.29%); Waaree BiH-11-705 tolerates heat better (temp coeff -0.240%/°C vs -0.340%/°C). See the full spec comparison and 30-year energy simulation above for a complete picture.
What is the efficiency of Waaree Bi-68-665 and Waaree BiH-11-705?
Waaree Bi-68-665 has a module efficiency of 21.29%, while Waaree BiH-11-705 is 22.70%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does Waaree Bi-68-665 use vs Waaree BiH-11-705?
Waaree Bi-68-665 uses PERC cells; Waaree BiH-11-705 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 Bi-68-665 and Waaree BiH-11-705?
Waaree Bi-68-665 has a 30 years power warranty; Waaree BiH-11-705 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 Bi-68-665 and Waaree BiH-11-705 bifacial panels?
Both Waaree Bi-68-665 and Waaree BiH-11-705 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.
