Solar-Fabrik Mono S4 Halfcut BC Full Black 475W vs Solar-Fabrik Mono S4 Halfcut BC Series Full Black 475W

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

Solar-Fabrik Mono S4 Halfcut BC Full Black 475W has a module efficiency of 23.30%, while Solar-Fabrik Mono S4 Halfcut BC Series 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 Halfcut BC Full Black 475W use vs Solar-Fabrik Mono S4 Halfcut BC Series Full Black 475W?

Solar-Fabrik Mono S4 Halfcut BC Full Black 475W uses Back Contact cells; Solar-Fabrik Mono S4 Halfcut BC Series 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 Halfcut BC Full Black 475W and Solar-Fabrik Mono S4 Halfcut BC Series Full Black 475W?

Solar-Fabrik Mono S4 Halfcut BC Full Black 475W has a 30 years power warranty; Solar-Fabrik Mono S4 Halfcut BC Series 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 Halfcut BC Full Black 475W and Solar-Fabrik Mono S4 Halfcut BC Series Full Black 475W bifacial panels?

Both Solar-Fabrik Mono S4 Halfcut BC Full Black 475W and Solar-Fabrik Mono S4 Halfcut BC Series 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.

The verdict

Identical on every published parameter

All 17 comparable parameters agree, with 2 more left out because at least one datasheet does not publish them. 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.
