At its core are **N-type monocrystalline TOPCon cells**, which, compared to conventional PERC, degrade more slowly over time and perform better under high temperatures, translating into higher energy yield across the module's full lifespan. The panel features a **bifacial glass-glass construction**, allowing light reflected from rooftops, gravel, or light-colored surfaces to be converted into additional energy on the rear side, boosting the profitability of installations on industrial and commercial buildings without increasing the mounting footprint. The dual-glass design eliminates the backsheet degradation issues typical of film-based laminates and improves resistance to micro-cracks and moisture ingress, which is particularly valuable on roofs exposed to salty air or ammonia fumes. The manufacturer backs this durability with a **25-year product warranty and a 30-year linear performance warranty**, supported by resistance to PID, salt mist, and ammonia, making the series a strong choice for agricultural and industrial businesses as well as PV plant developers seeking a low LCOE. ## Notable figures - At 23.6% efficiency, this panel is 1.1pp above typical \*\*N-type 500-550W\*\* modules (median: 22.6%) - 236.2 W/m² power density - 10.9 W/m² more than \*\*N-type 500-550W\*\* median (225.3 W/m²), more power per roof area - At -0.28%/°C, hot weather performance is typical for \*\*N-type 500-550W\*\* panels - Weight of 27.4 kg is 1.2 kg above \*\*N-type 500-550W\*\* median (26.2 kg) - verify structural support - Bifaciality factor of 80% can add 4-12% extra yield with reflective mounting surface ## Questions ### What is the maximum power output of the WINAICO WST-NCX54-AW panel and what drives it? The top variant of the WST-NCX54-AW series reaches a maximum power of 525 Wp. This high output is achieved through N-type monocrystalline TOPCon cells, which convert sunlight more efficiently than conventional PERC cells, combined with a bifacial glass-glass design that captures additional reflected light from the rear side of the module. ### How does TOPCon cell technology in WINAICO panels differ from older PERC modules? TOPCon is an N-type cell technology that, compared to PERC, shows a slower power degradation rate over time and better performance at high temperatures - a key advantage on hot commercial and industrial rooftops. In practice, this results in higher cumulative energy yield over the 25-30 year system lifetime compared to cheaper PERC panels. ### Do bifacial WST-NCX54-AW panels actually generate more energy in commercial installations? Yes, the double-sided glass-glass construction captures light reflected off the roof, gravel, or light-colored surfaces from the rear side of the module without requiring additional mounting area. The actual gain depends on ground albedo and mounting height, but on typical industrial rooftops or ground-mount farms it translates into a measurable increase in annual energy production from the same number of panels. ### What warranty comes with WINAICO WST-NCX54-AW panels and what does it actually cover? The manufacturer provides a 25-year product warranty and a 30-year linear power performance warranty, meaning a gradual, predictable power decline rather than sudden degradation. The panels also have confirmed resistance to PID, salt mist, and ammonia, which matters for warranty claims on installations near coastlines or agricultural sites. ### Is the glass-glass construction of the WST-NCX54-AW more resistant to moisture and microcracks than standard backsheet panels? Yes, the rigid frame with glass on both sides eliminates the laminate degradation issues typical of backsheet panels and increases resistance to microcracks and moisture ingress. This is particularly valuable for rooftops exposed to salty coastal air or ammonia vapors, such as those found on livestock barns and farm buildings. ### What type of projects is the WINAICO WST-NCX54-AW series best suited for? This is a commercial-grade module built for agricultural and industrial businesses as well as solar farm developers focused on low LCOE over a long investment horizon. As a Taiwanese manufacturer, WINAICO holds Tier 1 status, which in practice means stronger project bankability and easier financing from banks and investment funds. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/WINAICO_WST-525NCX54-AW_EU_0126-6fb61e93698e.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [Longi Solar LR7-54HJD-510M](https://comparepv.com/panel/longi-lr7-54hjd-510m) | 510 W | Cooler, lighter, +1.4 pp | | [AIKO AIKO-A495-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a495-mce54mw) | 495 W | -30 W, lighter, +1.2 pp | | [Longi Solar LR7-60HVH-560M](https://comparepv.com/panel/longi-lr7-60hvh-560m) | 560 W | +35 W, lighter, +1.2 pp | | [Longi Solar LR7-54HJD-505M](https://comparepv.com/panel/longi-lr7-54hjd-505m) | 505 W | Cooler, lighter, +1.1 pp | | [WINAICO WST-505BKX54-A2](https://comparepv.com/panel/winaico-wst-505bkx54-a2) | 505 W | Cooler, lighter, +1.1 pp | | [Longi Solar LR7-60HVH-555M](https://comparepv.com/panel/longi-lr7-60hvh-555m) | 555 W | +30 W, lighter, +1.0 pp | | [AIKO AIKO-A490-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a490-mce54mw) | 490 W | -35 W, lighter, +0.9 pp | | [WINAICO WST-510NHX54-A4](https://comparepv.com/panel/winaico-wst-510nhx54-a4) | 510 W | -15 W, cooler, -0.7 pp | | [WINAICO WST-515NHX54-A4](https://comparepv.com/panel/winaico-wst-515nhx54-a4) | 515 W | -10 W, cooler, -0.4 pp | | [WINAICO WST-520NCX54-AW](https://comparepv.com/panel/winaico-wst-520ncx54-aw) | 520 W | -0.2 pp | | [Longi Solar LR7-60HVHL-550M](https://comparepv.com/panel/longi-lr7-60hvhl-550m) | 550 W | +25 W, lighter, +0.8 pp | | [JA Solar JAT60S40-540/LR](https://comparepv.com/panel/ja-solar-jat60s40-540-lr) | 540 W | Cooler, lighter, +0.8 pp | | [Gokin GK-5-60HG-540M](https://comparepv.com/panel/gokin-gk-5-60hg-540m) | 540 W | Cooler, lighter, +0.8 pp | | [Jinko Solar JKM545-54QL6-DV-F1-EU](https://comparepv.com/panel/jinko-solar-jkm545-54ql6-dv-f1-eu) | 545 W | +20 W, cooler, +0.7 pp | | [Longi Solar LR7-60HVH-545M](https://comparepv.com/panel/longi-lr7-60hvh-545m) | 545 W | Cooler, lighter, +0.6 pp | --- Source: https://comparepv.com/panel/winaico-wst-525ncx54-aw 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.
