Space saver, heavy for its output
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.

Top 22% of the TOPCon 500-550 W segment, against a median of 227.4.
Top 23% of the TOPCon 500-550 W segment, against a median of 22.74%.
Bottom 9% of the TOPCon 500-550 W segment, against a median of 52.5. Ranked 10,478th in the whole database.
Bottom 9% of the TOPCon 500-550 W segment, against a median of -0.290. Ranked 8,163rd in the whole database.
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.
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.
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.
WINAICO (Taiwan, founded 2003) is regarded as a bankable manufacturer, easing project financing and reducing risk for investors seeking predictable returns on commercial installations.
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.
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.
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.
- At 23.1% efficiency, this panel is on par with typical TOPCon 500-550W modules
- Power density of 231.1 W/m² packs 3.7 W/m² more into the same footprint vs TOPCon 500-550W median (227.4 W/m²)
- Temperature coefficient of -0.31%/°C is 0.02pp worse than TOPCon 500-550W median (-0.29%/°C) - higher losses in summer heat
- At 28.0 kg, weight matches the TOPCon 500-550W median
- 80% bifaciality enables rear-side power generation, boosting yield by 4-12% on reflective surfaces
