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 (-0.290 %/°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: Sunova TS-BBT78(625) or Sunova TS-BBT78(630)?
According to our database: Sunova TS-BBT78(630) has higher module efficiency (22.50% vs 22.40%). See the full spec comparison and 30-year energy simulation above for a complete picture.
What is the efficiency of Sunova TS-BBT78(625) and Sunova TS-BBT78(630)?
Sunova TS-BBT78(625) has a module efficiency of 22.40%, while Sunova TS-BBT78(630) is 22.50%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does Sunova TS-BBT78(625) use vs Sunova TS-BBT78(630)?
Sunova TS-BBT78(625) uses N-type cells; Sunova TS-BBT78(630) 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 Sunova TS-BBT78(625) and Sunova TS-BBT78(630)?
Sunova TS-BBT78(625) has a 30 years power warranty; Sunova TS-BBT78(630) 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 Sunova TS-BBT78(625) and Sunova TS-BBT78(630) bifacial panels?
Both Sunova TS-BBT78(625) and Sunova TS-BBT78(630) 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.
