What sets it apart is its **DIBt certification with so-called overhead approval**, confirming compliance with Germany's elevated building safety requirements - allowing the module to be mounted not only on pitched roofs but also in locations where users are positioned directly underneath the panel surface. This makes Trend Guard an excellent **solution for carports, terrace roof canopies, facades, and entrance areas**, where conventional panels often fail to meet safety standards. The construction is based on a **bifacial glass-glass module with monocrystalline N-Type TOPCon half-cut cells**, delivering additional energy yield from the rear side of the panel along with high mechanical resistance. Glass on both sides increases durability and reduces the risk of degradation caused by ammonia, salt, or hail, making this module an attractive choice for agricultural, coastal, and commercial installations with demanding operating conditions. The manufacturer backs the series with a **30-year product warranty and linear power warranty**, reflecting confidence in the technology's long-term reliability. Trend Guard is designed for investors and installers seeking a module that combines the aesthetics of a black frame, institutionally certified safety, and strong energy performance in demanding mounting environments. ## Notable figures - Efficiency of 22.8% matches the \*\*TOPCon 450-500W\*\* median - Power density of 227.7 W/m² matches the \*\*TOPCon 450-500W\*\* median - Temperature coefficient of -0.29%/°C matches the \*\*TOPCon 450-500W\*\* median - Bifaciality factor of 80% can add 4-12% extra yield with reflective mounting surface - In the top 22% for efficiency among all TOPCon panels ## Questions ### What is the DIBt overhead certification on Solar-Fabrik Mono S4 Halfcut Trend Guard panels? It is a German building certification confirming the module meets elevated structural safety requirements and can be installed in locations where people are directly underneath it, such as canopies or shelters. Standard PV panels typically lack this certification, limiting their use to conventional sloped roofs. ### Is the Trend Guard suitable for carport or patio canopy installations? Yes, this is one of the series' main applications. Thanks to the DIBt overhead approval, the module can be safely mounted above areas where people are present - carports, patio canopies, facades, and entrance zones. The dual-glass construction also adds mechanical resistance in these applications. ### What do bifacial design and N-Type TOPCon technology offer in this module? The panel uses N-Type TOPCon monocrystalline half-cut cells in a bifacial configuration, generating additional energy from the rear side via light reflected off the ground. This results in a higher energy yield compared to classic monofacial modules, especially with light-colored surfaces or installations over water, gravel, or reflective roofing. ### What warranty comes with the Solar-Fabrik Mono S4 Halfcut Trend Guard panels? The manufacturer provides a 30-year product warranty along with a 30-year linear power warranty. This means long-term coverage for both material and workmanship defects as well as gradual power degradation, making it one of the longer warranty periods currently available on the PV market. ### Does the dual-glass construction of the Trend Guard improve resistance to harsh conditions like hail or salt exposure? Yes, the dual-glass design protects the cells on both sides, reducing the risk of degradation caused by moisture, ammonia, salt, or hail impact. This makes the module well-suited for agricultural, coastal, and commercial installations where operating conditions are more demanding than a typical residential setup. ### What is the maximum power output of the Trend Guard series and which installations is it suited for? The module reaches a maximum power output of up to 455 Wp. Combined with TOPCon technology and bifacial design, it works well for rooftop installations as well as commercial or industrial projects requiring high efficiency and certified overhead safety, such as company parking canopies. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/au_s4_tg_455_hc_96_de-950833567d11.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [AIKO AIKO-A495-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a495-mce54mw) | 495 W | +40 W, lighter, +2.0 pp | | [Longi Solar LR7-54HJD-505M](https://comparepv.com/panel/longi-lr7-54hjd-505m) | 505 W | +50 W, cooler, +1.9 pp | | [AIKO AIKO-A490-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a490-mce54mw) | 490 W | +35 W, lighter, +1.7 pp | | [Longi Solar LR7-54HJD-500M](https://comparepv.com/panel/longi-lr7-54hjd-500m) | 500 W | +45 W, cooler, +1.7 pp | | [Talesun CIPRO-TN9C54M-500W](https://comparepv.com/panel/talesun-cipro-tn9c54m-500w) | 500 W | +45 W, lighter, +1.7 pp | | [Gokin GK-3-54HGb-500M](https://comparepv.com/panel/gokin-gk-3-54hgb-500m) | 500 W | +45 W, lighter, +1.7 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 | -55 W, -2.8 pp | | [Solar-Fabrik Mono S4 Halfcut Chroma Orange 420W](https://comparepv.com/panel/solar-fabrik-mono-s4-halfcut-chroma-orange-420w) | 420 W | -35 W, -1.8 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 | -10 W, -0.5 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 | -0.3 pp | | [Longi Solar LR7-54HJD-510M](https://comparepv.com/panel/longi-lr7-54hjd-510m) | 510 W | +55 W, cooler, +2.2 pp | --- Source: https://comparepv.com/panel/solar-fabrik-mono-s4-halfcut-trend-guard-455-w 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.
