Solar-Fabrik Mono S4 Quartercut Premium DE Series 485W vs Solar-Fabrik Mono S4 Halfcut BC Full Black 475W

Q: What is the efficiency of Solar-Fabrik Mono S4 Quartercut Premium DE Series 485W and Solar-Fabrik Mono S4 Halfcut BC Full Black 475W?

Solar-Fabrik Mono S4 Quartercut Premium DE Series 485W has a module efficiency of 24.27%, while Solar-Fabrik Mono S4 Halfcut BC Full Black 475W is 23.30%. Higher efficiency means more electricity from the same roof area - useful when space is limited.

Q: What cell technology does Solar-Fabrik Mono S4 Quartercut Premium DE Series 485W use vs Solar-Fabrik Mono S4 Halfcut BC Full Black 475W?

Solar-Fabrik Mono S4 Quartercut Premium DE Series 485W uses TOPCon cells; Solar-Fabrik Mono S4 Halfcut BC Full Black 475W uses Back Contact. Modern n-type technologies (TOPCon, HJT, BC) typically deliver higher efficiency and lower degradation compared to older PERC (p-type) cells.

Q: What is the warranty on Solar-Fabrik Mono S4 Quartercut Premium DE Series 485W and Solar-Fabrik Mono S4 Halfcut BC Full Black 475W?

Solar-Fabrik Mono S4 Quartercut Premium DE Series 485W has a 30 years power warranty; Solar-Fabrik Mono S4 Halfcut BC Full Black 475W 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.

Q: Are Solar-Fabrik Mono S4 Quartercut Premium DE Series 485W and Solar-Fabrik Mono S4 Halfcut BC Full Black 475W bifacial panels?

Both Solar-Fabrik Mono S4 Quartercut Premium DE Series 485W and Solar-Fabrik Mono S4 Halfcut BC Full Black 475W 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.

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

Cell temperature

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.
