Questions about this pairing

Which panel is better: Vikram Solar SURYAVA VSMDH.66.735.05 or Vikram Solar HYPERSOL VSMDH.78.630.05?
According to our database: Vikram Solar SURYAVA VSMDH.66.735.05 has higher module efficiency (23.66% vs 22.62%); Vikram Solar SURYAVA VSMDH.66.735.05 tolerates heat better (temp coeff -0.260%/°C vs -0.300%/°C). See the full spec comparison and 30-year energy simulation above for a complete picture.
What is the efficiency of Vikram Solar SURYAVA VSMDH.66.735.05 and Vikram Solar HYPERSOL VSMDH.78.630.05?
Vikram Solar SURYAVA VSMDH.66.735.05 has a module efficiency of 23.66%, while Vikram Solar HYPERSOL VSMDH.78.630.05 is 22.62%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does Vikram Solar SURYAVA VSMDH.66.735.05 use vs Vikram Solar HYPERSOL VSMDH.78.630.05?
Vikram Solar SURYAVA VSMDH.66.735.05 uses HJT cells; Vikram Solar HYPERSOL VSMDH.78.630.05 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 Vikram Solar SURYAVA VSMDH.66.735.05 and Vikram Solar HYPERSOL VSMDH.78.630.05?
Vikram Solar SURYAVA VSMDH.66.735.05 has a 30 years power warranty; Vikram Solar HYPERSOL VSMDH.78.630.05 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 Vikram Solar SURYAVA VSMDH.66.735.05 and Vikram Solar HYPERSOL VSMDH.78.630.05 bifacial panels?
Both Vikram Solar SURYAVA VSMDH.66.735.05 and Vikram Solar HYPERSOL VSMDH.78.630.05 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.

Every figure here is from the manufacturers' own datasheets - a dash means the value is not published, never an estimate. The thirty-year projection and the temperature scenarios are calculations from those figures, and each states its assumption above.
