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 (-0.300 %/°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: Avaada AVN66G12RG-620 or Avaada AVN66G12RG-625?
According to our database: Avaada AVN66G12RG-625 has higher module efficiency (23.14% vs 23.00%). See the full spec comparison and 30-year energy simulation above for a complete picture.
What is the efficiency of Avaada AVN66G12RG-620 and Avaada AVN66G12RG-625?
Avaada AVN66G12RG-620 has a module efficiency of 23.00%, while Avaada AVN66G12RG-625 is 23.14%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does Avaada AVN66G12RG-620 use vs Avaada AVN66G12RG-625?
Avaada AVN66G12RG-620 uses TOPCon cells; Avaada AVN66G12RG-625 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 Avaada AVN66G12RG-620 and Avaada AVN66G12RG-625?
Avaada AVN66G12RG-620 has a 30 years power warranty; Avaada AVN66G12RG-625 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 Avaada AVN66G12RG-620 and Avaada AVN66G12RG-625 bifacial panels?
Both Avaada AVN66G12RG-620 and Avaada AVN66G12RG-625 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.
