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. ## The two panels | Attribute | A | B | | --- | --- | --- | | Panel | [Solar-Fabrik Mono S4 Halfcut BC Series Black 480W](https://comparepv.com/panel/solar-fabrik-mono-s4-halfcut-bc-series-black-480w) | [Solar-Fabrik Mono S4 Halfcut BC Series Full Black 480W](https://comparepv.com/panel/solar-fabrik-mono-s4-halfcut-bc-series-full-black-480w) | | Manufacturer | Solar-Fabrik | Solar-Fabrik | | Power | 480 Wp | 480 Wp | | Efficiency | 23.50 % | 23.50 % | | Technology | Back Contact | Back Contact | ## Every compared parameter | Parameter | Black 480W | Full Black 480W | | --- | --- | --- | | Rated power | 480 Wp | 480 Wp | | Module efficiency | 23.50 % | 23.50 % | | Power density | 235.2 Wp/m² | 235.2 Wp/m² | | Open-circuit voltage | 40.53 V | 40.53 V | | Voltage at max power | 33.51 V | 33.51 V | | Short-circuit current | 14.98 A | 14.98 A | | Current at max power | 14.33 A | 14.33 A | | Temperature coefficient | - | - | | Dimensions | 1800x1134x30 mm | 1800x1134x30 mm | | Module area | 2.041 m² | 2.041 m² | | Weight | 25.0 kg | 25.0 kg | | Weight per kWp | 52.1 kg/kWp | 52.1 kg/kWp | | Product warranty | 30 yrs | 30 yrs | | Performance warranty | 30 yrs | 30 yrs | | Annual degradation | - | - | | Cell technology | Back Contact | Back Contact | | Cell type | Monocrystalline | Monocrystalline | | Cell count | 108 | 108 | | Bifacial | Yes | Yes | ## Thirty-year yield A 1.0% first-year loss then 0.40% a year, assumed for both panels, at 1,200 kWh/kWp a year Projected at 25 °C. Neither datasheet publishes this, so a hotter case cannot be shown without inventing one side of it. - **Cumulative output, Black 480W:** 16,105 kWh - **Cumulative output, Full Black 480W:** 16,105 kWh - **Gap:** No difference ## Against the whole database | Measure | Black 480W | Full Black 480W | Out of | Note | | --- | --- | --- | --- | --- | | Efficiency | #716 | #716 | 14,005 | Tied - the same position in the database | | Power density | #718 | #718 | 14,005 | Tied - the same position in the database | | Heat behaviour | #13,924 | #13,924 | 14,005 | Tied - the same position in the database | | Weight | #5,516 | #5,516 | 14,005 | Tied - the same position in the database | | Warranty | #21 | #21 | 14,005 | Tied - the same position in the database | | Overall | #2,993 | #2,993 | 14,005 | Tied - the same position in the database | ## Questions ### Which panel is better: Solar-Fabrik Mono S4 Halfcut BC Series Black 480W or Solar-Fabrik Mono S4 Halfcut BC Series Full Black 480W? 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 Series Black 480W and Solar-Fabrik Mono S4 Halfcut BC Series Full Black 480W? **Solar-Fabrik Mono S4 Halfcut BC Series Black **480 W**** has a module efficiency of **23.50%**, while **Solar-Fabrik Mono S4 Halfcut BC Series Full Black **480 W**** is **23.50%**. 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 Series Black 480W use vs Solar-Fabrik Mono S4 Halfcut BC Series Full Black 480W? **Solar-Fabrik Mono S4 Halfcut BC Series Black **480 W**** uses **Back Contact** cells; **Solar-Fabrik Mono S4 Halfcut BC Series Full Black **480 W**** 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 Series Black 480W and Solar-Fabrik Mono S4 Halfcut BC Series Full Black 480W? **Solar-Fabrik Mono S4 Halfcut BC Series Black **480 W**** has a **30 years** power warranty; **Solar-Fabrik Mono S4 Halfcut BC Series Full Black **480 W**** 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 Series Black 480W and Solar-Fabrik Mono S4 Halfcut BC Series Full Black 480W bifacial panels? Both **Solar-Fabrik Mono S4 Halfcut BC Series Black **480 W**** and **Solar-Fabrik Mono S4 Halfcut BC Series Full Black **480 W**** 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. ## Related comparisons - [Solar-Fabrik Mono S4 Halfcut BC Series Black 480W vs Solar-Fabrik Mono S4 Halfcut BC Series White 490W](https://comparepv.com/compare/solar-fabrik-mono-s4-halfcut-bc-series-black-480w/solar-fabrik-mono-s4-halfcut-bc-series-white-490w) - 3 differences, the largest is module efficiency - [Solar-Fabrik Mono S4 Halfcut BC Series Black 480W vs Solar-Fabrik Mono S4 Halfcut BC Series White 485W](https://comparepv.com/compare/solar-fabrik-mono-s4-halfcut-bc-series-black-480w/solar-fabrik-mono-s4-halfcut-bc-series-white-485w) - One difference: module efficiency - [Solar-Fabrik Mono S4 Halfcut BC Series Black 480W vs Solar-Fabrik Mono S4 Halfcut BC Series Black 475W](https://comparepv.com/compare/solar-fabrik-mono-s4-halfcut-bc-series-black-480w/solar-fabrik-mono-s4-halfcut-bc-series-black-475w) - One difference: module efficiency - [Solar-Fabrik Mono S4 Halfcut BC Series Black 480W vs Solar-Fabrik Mono S4 Halfcut BC Series Full Black 475W](https://comparepv.com/compare/solar-fabrik-mono-s4-halfcut-bc-series-black-480w/solar-fabrik-mono-s4-halfcut-bc-series-full-black-475w) - One difference: module efficiency - [Solar-Fabrik Mono S4 Halfcut BC Series Black 480W vs Solar-Fabrik S4-DG625-132TMax](https://comparepv.com/compare/solar-fabrik-mono-s4-halfcut-bc-series-black-480w/solar-fabrik-s4-dg625-132tmax) - 14 differences, the largest is rated power - [Solar-Fabrik Mono S4 Halfcut BC Series Black 480W vs Solar-Fabrik S4-DG620-132TMax](https://comparepv.com/compare/solar-fabrik-mono-s4-halfcut-bc-series-black-480w/solar-fabrik-s4-dg620-132tmax) - 15 differences, the largest is rated power --- Source: https://comparepv.com/compare/solar-fabrik-mono-s4-halfcut-bc-series-black-480w/solar-fabrik-mono-s4-halfcut-bc-series-full-black-480w Not in this file, on the page: the thirty-year yield curve year by year at a cell temperature you pick and a written summary generated on request.
