Space saver, heavy for its output
The WINAICO WST-NGX60-AB series consists of dual-glass N-type modules built on TOPCon technology, engineered for commercial and residential installations where maximizing energy yield per square meter of roof matters most. The use of bifacial cells lets the panel capture light reflected off the surrounding surface, meaningfully boosting energy production without adding to the installation's footprint, which is especially valuable on sites with light-colored roofing or ground-mounted arrays. The glass-glass construction, with two layers of 2.0 mm tempered glass replacing the traditional backsheet, significantly improves resistance to moisture ingress, microcracking, and PID degradation, extending module lifespan in demanding operating conditions. As a result, the manufacturer backs the series with one of the longer linear performance warranties on the market, spanning three decades of operation with minimal annual power loss. The series fits equally well on commercial rooftops and industrial buildings as it does in residential PV systems, where investors are focused on keeping LCOE low across the full lifecycle of the installation. A sturdy, anodized aluminum frame along with certified resistance to salt mist and ammonia corrosion make these panels a solid choice for agricultural and coastal sites, where standard modules tend to lose performance faster.
Ranking
Signals from the data
Roofs where every square metre counts and small roofs that need every watt.
Weight-limited structures and hot climates.
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 10% of the TOPCon 500-550 W segment, against a median of 52.5.
Bottom 21% of the TOPCon 500-550 W segment, against a median of -0.290.
Efficiency of 22.9-23.1% outperforms comparable 500 Wp modules such as Silfab SIL HM (21%) and Selfa SV120M.2.4 (22.6%), delivering higher energy yield per rooftop area.
Two layers of 2.0 mm tempered glass replace the traditional backsheet, significantly reducing PID degradation and microcrack risk, while bifaciality captures reflected light for extra yield, especially on light-colored roofs and ground-mount structures.
A 30-year performance warranty is among the longest in the segment, directly supporting lower LCOE across the installation's full lifecycle.
Founded in 2003 in Taiwan, WINAICO holds bankable Tier-1 status, reducing financial risk for bank or leasing-financed projects.
Certified frame corrosion resistance makes the series well-suited for agricultural and coastal installations, where standard modules degrade faster.
At 22.9-23.1%, efficiency is notably lower than the Gokin GK-3-54HGF (24.5%) at the same 500 Wp power class, meaning potentially lower energy yield per square meter versus newer competing modules.
The 15-year product warranty lags behind the 25-year standard increasingly offered by Tier-1 manufacturers on new-generation TOPCon modules, even though the power warranty reaches 30 years.
- 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)
- At -0.30%/°C, hot weather performance is typical for TOPCon 500-550W panels
- Bifacial design (80% factor) captures reflected light - adds 4-12% yield on ground-mount or white roof
- Ranked #1660 out of 14269 panels for efficiency in the database
