The verdict
Identical on every published parameter
All 18 comparable parameters agree, with 1 more left out because at least one datasheet does not publish it. 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
A 1.0% first-year loss then 0.40% a year, assumed for both panels, 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: Solar-Fabrik S4-DG620-132TMax or Solar-Fabrik S4-DG625-132TMax?
According to our database: Solar-Fabrik S4-DG625-132TMax has higher module efficiency (23.14% vs 22.95%). See the full spec comparison and 30-year energy simulation above for a complete picture.
What is the efficiency of Solar-Fabrik S4-DG620-132TMax and Solar-Fabrik S4-DG625-132TMax?
Solar-Fabrik S4-DG620-132TMax has a module efficiency of 22.95%, while Solar-Fabrik S4-DG625-132TMax is 23.14%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does Solar-Fabrik S4-DG620-132TMax use vs Solar-Fabrik S4-DG625-132TMax?
Solar-Fabrik S4-DG620-132TMax uses TOPCon cells; Solar-Fabrik S4-DG625-132TMax 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 Solar-Fabrik S4-DG620-132TMax and Solar-Fabrik S4-DG625-132TMax?
Solar-Fabrik S4-DG620-132TMax has a 25 years power warranty; Solar-Fabrik S4-DG625-132TMax has a 25 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 Solar-Fabrik S4-DG620-132TMax and Solar-Fabrik S4-DG625-132TMax bifacial panels?
Both Solar-Fabrik S4-DG620-132TMax and Solar-Fabrik S4-DG625-132TMax 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.
