The panels use **monocrystalline N-type TOPCon bifacial cells**, allowing the module to harvest additional energy from its rear side and deliver a higher yield from the same roof area. The **glass-glass construction**, with thicker tempered glass on both sides and a reinforced frame, significantly improves resistance to hail, wind, and snow loads, which matters in Central European climate conditions. The BW designation stands for **full black** design - the rear glass is partially black-printed and the frame is black-anodized aluminum, so the module blends seamlessly into the roof surface without sacrificing the benefits of bifacial energy generation. The series is also notable for its **30-year product and linear power warranty** with a very low annual degradation rate, lowering the levelized cost of energy (LCOE) over the system's lifetime. It's a solid choice for investors seeking a balance between maximum performance, durability, and a sleek rooftop aesthetic. ## Notable figures - 23.3% module efficiency - 0.8pp better than the \*\*N-type 450-500W\*\* median of 22.5% - 232.7 W/m² power density - 7.4 W/m² more than \*\*N-type 450-500W\*\* median (225.3 W/m²), more power per roof area - Temperature coefficient of -0.28%/°C matches the \*\*N-type 450-500W\*\* median - At 25.0 kg (1.3 kg above \*\*N-type 450-500W\*\* median of 23.7 kg), requires checking roof load capacity - Bifaciality factor of 80% can add 4-12% extra yield with reflective mounting surface ## Questions ### How does the BW version of the WINAICO WST-NCX48-BW series differ from standard bifacial modules? The BW (full black) designation means the module has a black anodized frame and a partially black-printed rear glass. This gives the panel a uniform black look on the roof, similar to classic monofacial modules, while still retaining the ability to generate energy from the rear side. It's designed for buyers who want aesthetics without giving up the extra yield from bifacial technology. ### How much extra energy does bifaciality add in WST-NCX48-BW panels compared to a regular panel? The additional rear-side yield depends on installation conditions - ground albedo, tilt angle, and mounting height above the surface. In typical rooftop installations over a light-colored roof, or in ground-mounted systems, you can expect a few to over ten percent more annual energy than a monofacial panel of the same rated power, without increasing roof area. ### What warranty does WINAICO offer on the WST-NCX48-BW series and what does it cover? The series comes with a 30-year product warranty and a 30-year linear power warranty. This means WINAICO guarantees not only mechanical and electrical reliability but also a very low, predictable annual power degradation rate over that entire period. It's one of the longer warranties on the market, reducing the levelized cost of electricity (LCOE) over the system's lifetime. ### Is the glass-glass construction in the WST-NCX48-BW more hail-resistant than standard panels? Yes, the modules use thickened, tempered glass on both sides along with a reinforced frame, significantly increasing resistance to hail impact, strong wind, and snow load compared to a classic glass-backsheet construction. This design also reduces laminate degradation over time, supporting the manufacturer's stated 30-year durability. ### Does N-type TOPCon cell technology in WINAICO panels perform better in low temperatures and low-light conditions? N-type TOPCon cells have a lower temperature coefficient of power than conventional P-type cells, meaning smaller efficiency losses on hot summer days. They also respond better to low and diffuse irradiance, resulting in more stable energy production on cloudy days and during winter when sunlight is weaker. ### Is WINAICO, as a Taiwan-based manufacturer, a reliable choice for a long-term panel investment? WINAICO is a Tier 1 manufacturer headquartered in Taiwan, with many years of presence in the PV market, confirming its financial and production stability. Tier 1 status means the company is regularly financed by banks and leasing institutions for commercial investments, which further supports the credibility of its long-term warranties, including the 30-year coverage on the WST-NCX48-BW series. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/WINAICO_WST-465NCX48-BW_EU_0126-732d85cbd660.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [Longi Solar LR7-54HJD-510M](https://comparepv.com/panel/longi-lr7-54hjd-510m) | 510 W | +45 W, cooler, +1.7 pp | | [AIKO AIKO-A495-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a495-mce54mw) | 495 W | +30 W, lighter, +1.5 pp | | [Longi Solar LR7-54HJD-505M](https://comparepv.com/panel/longi-lr7-54hjd-505m) | 505 W | +40 W, cooler, +1.4 pp | | [WINAICO WST-505BKX54-A2](https://comparepv.com/panel/winaico-wst-505bkx54-a2) | 505 W | +40 W, cooler, +1.4 pp | | [AIKO AIKO-A490-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a490-mce54mw) | 490 W | +25 W, lighter, +1.2 pp | | [Longi Solar LR7-54HJD-500M](https://comparepv.com/panel/longi-lr7-54hjd-500m) | 500 W | +35 W, cooler, +1.2 pp | | [Talesun CIPRO-TN9C54M-500W](https://comparepv.com/panel/talesun-cipro-tn9c54m-500w) | 500 W | +35 W, lighter, +1.2 pp | | [WINAICO WST-450NFX54-B1 Full Black](https://comparepv.com/panel/winaico-wst-450nfx54-b1-full-black) | 450 W | -15 W, -0.8 pp | | [WINAICO WST-470NCX48-AW](https://comparepv.com/panel/winaico-wst-470ncx48-aw) | 470 W | Very close match | --- Source: https://comparepv.com/panel/winaico-wst-465ncx48-bw 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.
