Thanks to the use of **half-cut cell technology**, the modules minimize losses due to partial shading and reduce internal resistance, which directly translates into more stable and efficient operation of the entire system. **Glass-glass construction** provides exceptional mechanical strength and resistance to degradation, significantly extending the lifespan of the panels compared to solutions based on backsheet film. Bifacial cells absorb both direct and reflected light from the ground, effectively increasing the annual energy yield of the installation. **Tempered, anti-reflective glass on both sides** protects against salt corrosion, ammonia, and extreme weather conditions, and its resistance to hail Class 4 makes this panel ready for the variable Polish climate. **30-year product and linear warranty** confirms the manufacturer's confidence in the long-term durability of this series. ## Notable figures - Efficiency of 23.0% matches the \*\*TOPCon 450-500W\*\* median - Power density of 230.2 W/m² packs 5.0 W/m² more into the same footprint vs \*\*TOPCon 450-500W\*\* median (225.2 W/m²) - At -0.31%/°C, loses 0.02pp more power per degree than \*\*TOPCon 450-500W\*\* median (-0.29%/°C) - Bifacial design (80% factor) captures reflected light - adds 4-12% yield on ground-mount or white roof - #1797 for efficiency, #8005 for temperature performance out of 14005 panels ## Questions ### Why do Solar-Fabrik Mono S4 Halfcut Trend White panels feature white busbars, and does it affect their efficiency? The white busbar lines on the cells are primarily an aesthetic choice — the module looks brighter and blends seamlessly into light-colored roofs or facades. This design detail has no negative impact on performance: the TOPCon cell technology and half-cut architecture still deliver up to 455 W peak power. It is an ideal option wherever the visual appearance of the PV installation matters to the property owner. ### How does the TOPCon cell technology in the Mono S4 Trend White series compare to older PERC cells? TOPCon (Tunnel Oxide Passivated Contact) is an N-Type cell architecture with enhanced surface passivation. Compared to PERC, it offers higher module efficiency, a lower temperature coefficient (power output drops more slowly in heat), and better low-light performance. In practice, this results in higher annual energy yields, which is especially beneficial in Poland's variable climate with frequent overcast conditions. ### How much additional energy do I actually gain from the bifacial design of the Solar-Fabrik Mono S4 Trend White? In typical roof installations, the bifacial gain ranges from 5–15% in additional annual yield, depending on surface albedo. Light-colored membranes, gravel, or white cladding beneath the panels produce higher gains; dark roofing materials produce lower ones. The module captures both direct sunlight and light reflected off the surface below. The effect is most pronounced in ground-mounted systems or flat-roof installations with a light-colored substrate. ### What warranty comes with the Solar-Fabrik Mono S4 Halfcut Trend White panels, and what does it cover? The Mono S4 Halfcut Trend White series comes with a 30-year product warranty covering manufacturing defects and material faults, as well as a 30-year linear power output warranty. This guarantees that the module will maintain a defined minimum power level for three decades. It is one of the longest warranties currently available on the market, reflecting Solar-Fabrik's confidence in the long-term durability of the glass-glass TOPCon design. ### Do the Solar-Fabrik Mono S4 Trend White panels perform well in winter and low-light conditions? Yes. N-Type TOPCon cells have a low temperature coefficient, meaning they operate more efficiently on cold, bright winter days compared to PERC-based modules. The glass-glass construction is rated for heavy snow loads and extreme frost, and the hail resistance class 4 certification makes this panel a reliable choice for Central European climate conditions throughout the entire year. ### Is the glass-glass construction of the Solar-Fabrik Mono S4 Trend White resistant to corrosion and harsh weather? Yes. The dual-glass structure with anti-reflective tempered glass on both sides eliminates the risk of backsheet delamination and is certified resistant to salt mist corrosion, ammonia exposure (relevant for agricultural installations), and extreme temperature cycling. The panel holds a hail resistance class 4 rating, equivalent to 35 mm ice balls impacting at approximately 83 km/h, making it well-suited for demanding outdoor environments. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/au_s4_tw_455-460_hc_96_de-862f4776aa68.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [Longi Solar LR7-54HJD-510M](https://comparepv.com/panel/longi-lr7-54hjd-510m) | 510 W | +50 W, cooler, +2.0 pp | | [AIKO AIKO-A495-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a495-mce54mw) | 495 W | Cooler, lighter, +1.8 pp | | [Longi Solar LR7-54HJD-505M](https://comparepv.com/panel/longi-lr7-54hjd-505m) | 505 W | +45 W, cooler, +1.7 pp | | [AIKO AIKO-A490-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a490-mce54mw) | 490 W | Cooler, lighter, +1.5 pp | | [Longi Solar LR7-54HJD-500M](https://comparepv.com/panel/longi-lr7-54hjd-500m) | 500 W | +40 W, cooler, +1.5 pp | | [Talesun CIPRO-TN9C54M-500W](https://comparepv.com/panel/talesun-cipro-tn9c54m-500w) | 500 W | +40 W, cooler, +1.5 pp | | [Solar-Fabrik Mono S4 HC V 400 BF-DG](https://comparepv.com/panel/solar-fabrik-mono-s4-hc-v-400-bf-dg) | 400 W | -60 W, cooler, -3.0 pp | | [Solar-Fabrik Mono S4 Halfcut Chroma Orange 420W](https://comparepv.com/panel/solar-fabrik-mono-s4-halfcut-chroma-orange-420w) | 420 W | -40 W, cooler, -2.0 pp | | [Solar-Fabrik Mono S4 Halfcut Trend Full Black 445 W](https://comparepv.com/panel/solar-fabrik-mono-s4-halfcut-trend-full-black-445-w) | 445 W | -15 W, cooler, -0.7 pp | | [Solar-Fabrik Mono S4 Halfcut Trend Full Black 450 W](https://comparepv.com/panel/solar-fabrik-mono-s4-halfcut-trend-full-black-450-w) | 450 W | -10 W, cooler, -0.5 pp | | [Solar-Fabrik Mono S4 Halfcut Trend White 455W](https://comparepv.com/panel/solar-fabrik-mono-s4-halfcut-trend-white-455w) | 455 W | -0.2 pp | --- Source: https://comparepv.com/panel/solar-fabrik-mono-s4-halfcut-trend-white-460w Not in this file, on the page: a thirty-year output simulator, a bifacial gain calculator and alternatives filtered by how closely they match these dimensions.
