The verdict
Identical on every published parameter
All 19 comparable parameters agree. Two records this alike are usually one panel sold under two names, or two bins of the same production line - decide on price and on who you would rather buy from.

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 (-0.350 %/°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 PARADEA VSMDH.66.AAA.05-670 or Vikram Solar PARADEA VSMDH.66.AAA.05-675?
According to our database: Vikram Solar PARADEA VSMDH.66.AAA.05-675 has higher module efficiency (21.73% vs 21.57%). See the full spec comparison and 30-year energy simulation above for a complete picture.
What is the efficiency of Vikram Solar PARADEA VSMDH.66.AAA.05-670 and Vikram Solar PARADEA VSMDH.66.AAA.05-675?
Vikram Solar PARADEA VSMDH.66.AAA.05-670 has a module efficiency of 21.57%, while Vikram Solar PARADEA VSMDH.66.AAA.05-675 is 21.73%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does Vikram Solar PARADEA VSMDH.66.AAA.05-670 use vs Vikram Solar PARADEA VSMDH.66.AAA.05-675?
Vikram Solar PARADEA VSMDH.66.AAA.05-670 uses PERC cells; Vikram Solar PARADEA VSMDH.66.AAA.05-675 uses PERC. 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 PARADEA VSMDH.66.AAA.05-670 and Vikram Solar PARADEA VSMDH.66.AAA.05-675?
Vikram Solar PARADEA VSMDH.66.AAA.05-670 has a 30 years power warranty; Vikram Solar PARADEA VSMDH.66.AAA.05-675 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 PARADEA VSMDH.66.AAA.05-670 and Vikram Solar PARADEA VSMDH.66.AAA.05-675 bifacial panels?
Both Vikram Solar PARADEA VSMDH.66.AAA.05-670 and Vikram Solar PARADEA VSMDH.66.AAA.05-675 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.
