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 (-0.280 %/°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.66.AAA.05-705 or Vikram Solar HYPERSOL VSMDH.66.AAA.05-720?
According to our database: Vikram Solar HYPERSOL VSMDH.66.AAA.05-720 has higher module efficiency (23.18% vs 22.70%). See the full spec comparison and 30-year energy simulation above for a complete picture.
What is the efficiency of Vikram Solar HYPERSOL VSMDH.66.AAA.05-705 and Vikram Solar HYPERSOL VSMDH.66.AAA.05-720?
Vikram Solar HYPERSOL VSMDH.66.AAA.05-705 has a module efficiency of 22.70%, while Vikram Solar HYPERSOL VSMDH.66.AAA.05-720 is 23.18%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does Vikram Solar HYPERSOL VSMDH.66.AAA.05-705 use vs Vikram Solar HYPERSOL VSMDH.66.AAA.05-720?
Vikram Solar HYPERSOL VSMDH.66.AAA.05-705 uses N-type cells; Vikram Solar HYPERSOL VSMDH.66.AAA.05-720 uses N-type. 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.66.AAA.05-705 and Vikram Solar HYPERSOL VSMDH.66.AAA.05-720?
Vikram Solar HYPERSOL VSMDH.66.AAA.05-705 has a 30 years power warranty; Vikram Solar HYPERSOL VSMDH.66.AAA.05-720 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.66.AAA.05-705 and Vikram Solar HYPERSOL VSMDH.66.AAA.05-720 bifacial panels?
Both Vikram Solar HYPERSOL VSMDH.66.AAA.05-705 and Vikram Solar HYPERSOL VSMDH.66.AAA.05-720 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.
