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 (-0.260 %/°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 Mono S4 Halfcut BC White 480-490W or Solar-Fabrik Mono S4 Halfcut BC White 485?
According to our database: both panels are closely matched on key specs - the decision often comes down to price and local availability. See the full spec comparison and 30-year energy simulation above for a complete picture.
What is the efficiency of Solar-Fabrik Mono S4 Halfcut BC White 480-490W and Solar-Fabrik Mono S4 Halfcut BC White 485?
Solar-Fabrik Mono S4 Halfcut BC White 480-490 W has a module efficiency of 23.75%, while Solar-Fabrik Mono S4 Halfcut BC White 485 is 23.75%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does Solar-Fabrik Mono S4 Halfcut BC White 480-490W use vs Solar-Fabrik Mono S4 Halfcut BC White 485?
Solar-Fabrik Mono S4 Halfcut BC White 480-490 W uses Back Contact cells; Solar-Fabrik Mono S4 Halfcut BC White 485 uses Back Contact. 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 Mono S4 Halfcut BC White 480-490W and Solar-Fabrik Mono S4 Halfcut BC White 485?
Solar-Fabrik Mono S4 Halfcut BC White 480-490 W has a 30 years power warranty; Solar-Fabrik Mono S4 Halfcut BC White 485 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 Solar-Fabrik Mono S4 Halfcut BC White 480-490W and Solar-Fabrik Mono S4 Halfcut BC White 485 bifacial panels?
Both Solar-Fabrik Mono S4 Halfcut BC White 480-490 W and Solar-Fabrik Mono S4 Halfcut BC White 485 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.
