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: Vikram Solar HYPERSOL VSMDH.78.615.05 or Vikram Solar HYPERSOL VSMDH.78.625.05?
According to our database: Vikram Solar HYPERSOL VSMDH.78.625.05 has higher module efficiency (22.44% vs 22.08%). See the full spec comparison and 30-year energy simulation above for a complete picture.
What is the efficiency of Vikram Solar HYPERSOL VSMDH.78.615.05 and Vikram Solar HYPERSOL VSMDH.78.625.05?
Vikram Solar HYPERSOL VSMDH.78.615.05 has a module efficiency of 22.08%, while Vikram Solar HYPERSOL VSMDH.78.625.05 is 22.44%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does Vikram Solar HYPERSOL VSMDH.78.615.05 use vs Vikram Solar HYPERSOL VSMDH.78.625.05?
Vikram Solar HYPERSOL VSMDH.78.615.05 uses TOPCon cells; Vikram Solar HYPERSOL VSMDH.78.625.05 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 HYPERSOL VSMDH.78.615.05 and Vikram Solar HYPERSOL VSMDH.78.625.05?
Vikram Solar HYPERSOL VSMDH.78.615.05 has a 30 years power warranty; Vikram Solar HYPERSOL VSMDH.78.625.05 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 HYPERSOL VSMDH.78.615.05 and Vikram Solar HYPERSOL VSMDH.78.625.05 bifacial panels?
Both Vikram Solar HYPERSOL VSMDH.78.615.05 and Vikram Solar HYPERSOL VSMDH.78.625.05 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.
