The WINAICO WST-NGX60-AW series consists of N-type monocrystalline photovoltaic modules built on TOPCon technology, engineered for commercial and residential installations where maximizing energy yield from limited roof space is critical. The use of half-cut cells connected in series reduces resistive losses and improves resilience to partial shading, resulting in more stable performance under challenging irradiance conditions. The glass-glass (bifacial) construction captures additional light reflected from the ground or surrounding surfaces, boosting daily energy output without requiring any extra installation footprint. The black anodized aluminum frame delivers a clean, uniform aesthetic that works equally well on pitched residential roofs and large-scale commercial arrays. These panels stand out with a low power temperature coefficient, meaning they retain more output on hot days compared to conventional P-type modules. WINAICO backs the series with a 15-year product warranty and a 30-year linear performance guarantee, ensuring power output stays no lower than 87.4% at the end of the module's service life. This makes the series a solid choice for investors seeking predictable returns and a low LCOE over the long term.

What owners get
High-efficiency N-type TOPCon cells

Efficiency of 22.7-23.1% places the WST-NGX60-AW series clearly above peer comparables such as Silfab SIL HM (21%) and Selfa SV120M.2.4 (22.6%). N-type TOPCon cells exhibit lower LID/LeTID degradation than older PERC technology, translating into real-world higher annual yield from the same roof area.

Bifacial glass-glass dual-sided generation

The glass-glass bifacial construction captures reflected irradiance from the ground, increasing daily energy yield without expanding the installation footprint. Combined with half-cut cells, it reduces resistive losses and improves resilience to partial shading.

30-year linear power warranty

A guaranteed power level of no less than 87.4% after 30 years matches the standard WINAICO publishes for its N-type glass-glass modules (e.g., the WST-NGX48-AW series) and exceeds the typical 25-year warranties of competing P-type series, supporting lower long-term LCOE.

Tier-1, bankable manufacturer with 20+ years in the market

WINAICO (Taiwan, founded 2003) is regarded as a bankable manufacturer, easing project financing and reducing risk for investors seeking predictable returns on commercial installations.

Sleek black anodized aluminum frame

The black anodized frame delivers a uniform, aesthetic appearance well suited to both sloped residential rooftops and large-scale commercial applications where visual presentation matters.

Trade-offs
Shorter product warranty than other WINAICO N-type lines

The 15-year product warranty is shorter than the standard 30 years WINAICO publishes for its other N-type glass-glass modules (effective since 2023), creating an inconsistency against the identical 30-year performance warranty that may raise questions for investors about the reason for the shorter coverage.

Lower efficiency than the peer comparables leader

Maximum efficiency of 23.1% trails Gokin's GK-3-54HGF (24.5%) at the same 500 Wp power class, meaning a slightly larger roof footprint is needed for comparable energy generation.

Notes from the database
  • Efficiency of 22.9% matches the TOPCon 450-500W median
  • Power density of 228.8 W/m² packs 3.6 W/m² more into the same footprint vs TOPCon 450-500W median (225.2 W/m²)
  • -0.31%/°C temperature coefficient - 0.02pp worse than TOPCon 450-500W median (-0.29%/°C), expect higher hot weather losses
  • Weight of 28.0 kg is 4.0 kg above TOPCon 450-500W median (24.0 kg) - verify structural support
  • 80% bifaciality enables rear-side power generation, boosting yield by 4-12% on reflective surfaces

About the WST-NGX60-AW series

6 answered

These answers cover the whole series. Where a figure differs, the specification above is this module's own.

What is the maximum power output of the WINAICO WST-NGX60-AW solar panel?
Panels in the WST-NGX60-AW series reach a maximum power output of up to 500 Wp. This is achieved through N-type TOPCon half-cut cells, which reduce resistive losses and improve conversion efficiency compared to older P-type technology. For installations with limited roof space, this means higher energy yield from the same number of modules.
How does TOPCon technology in the WINAICO WST-NGX60-AW differ from conventional P-type panels?
TOPCon is an N-type technology that, compared to P-type, offers a lower temperature coefficient and reduced degradation over time. As a result, WST-NGX60-AW panels lose less efficiency on hot days and retain a higher percentage of nominal power after many years of operation, delivering more stable and predictable energy yield throughout the system's lifetime.
Do WINAICO WST-NGX60-AW bifacial panels require special installation?
The glass-glass construction with bifacial capability captures light reflected from the ground, but to maximize the energy gain, panels should ideally be mounted on high-profile racking or over reflective surfaces such as white gravel or reflective sheeting. Standard pitched-roof installation also works, though the bifacial gain will be less pronounced than on ground-mount or carport systems.
What warranty covers the WINAICO WST-NGX60-AW series?
WINAICO provides a 15-year product warranty along with a 30-year linear performance warranty, guaranteeing power output of at least 87.4% at the end of that period. This exceeds the market standard of typically 10-12 years for the product and 25 years for performance, making the series attractive for investors seeking a low LCOE over a long time horizon.
Is WINAICO a tier 1 manufacturer, and is it a trustworthy choice for a commercial investment?
Yes, WINAICO is a Taiwan-based manufacturer classified as tier 1, indicating financial stability, high production quality, and a long-standing market presence. For commercial and utility-scale installations, this status matters because it lowers the risk of warranty claim issues and ensures the modules meet international bankability standards for renewable energy projects.
Does the black frame on WST-NGX60-AW panels affect their performance?
The black anodized aluminum frame is primarily an aesthetic feature, giving the installation a uniform look that is especially valued on residential pitched roofs. It has no significant impact on energy performance, since key parameters like power output and yield depend on the TOPCon cell technology and bifacial construction rather than frame color.
