The WST-NCX48-AW series is a premium-class photovoltaic module line for residential applications, built around N-type TOPCon technology and a bifacial glass-glass construction. By converting light on both sides, these modules capture reflected irradiance from the ground, boosting energy yield by a significant margin without requiring extra roof space. The use of N-type monocrystalline cells translates into lower first-year degradation and more stable performance throughout the module's lifetime compared to conventional P-type solutions. The symmetrical glass-glass design, reinforced with a black anodized aluminum frame, adds mechanical resistance against snow and wind loads along with excellent sealing, making it particularly resistant to PID degradation and moisture ingress. This series is well suited to investors who prioritize long-term durability and minimal failure risk over decades of operation. It is the right choice for those who value a high product warranty and a predictable, linear power degradation curve, aiming to minimize the levelized cost of electricity across the full lifespan of their solar installation.

About the WST-NCX48-AW Series series

6 answered

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

How does N-type TOPCon technology in the WINAICO WST-NCX48-AW panels differ from conventional P-type cells?
N-type TOPCon cells have a lower first-year degradation rate (around -1%) and a slower annual power decline (around -0.4% per year) compared to P-type PERC technology. As a result, the WST-NCX48-AW retains over 87% of its original power output after 30 years, delivering a higher and more predictable energy yield throughout the system's lifetime.
How much extra energy does the bifacial design of the WST-NCX48-AW generate?
The glass-glass construction with bifacial cells captures light reflected off the ground through the rear side of the module. According to the manufacturer, bifaciality reaches up to 80%, and with a reflective surface and 10% additional rear irradiance, output can exceed the nominal 470 Wp rating by several dozen watts. Actual gains depend on mounting height, tilt angle, and the reflectivity of the surface beneath the panels.
What warranty comes with the WINAICO WST-NCX48-AW panels and what does it cover?
The WST-NCX48-AW series carries a 30-year product warranty and a 30-year linear power warranty. The product warranty covers material and workmanship defects, while the power warranty guarantees the module will maintain its stated performance level according to the degradation curve specified in the datasheet. This is among the longest warranty coverage currently available for premium-grade solar panels.
Are the WST-NCX48-AW panels resistant to moisture and PID degradation?
Yes, the symmetrical glass-glass construction with 2 mm glass on both sides and a black anodized 35 mm aluminum frame provides high module sealing and limits moisture ingress into the laminate. This build significantly reduces the risk of Potential Induced Degradation (PID) compared to modules with a polymer backsheet, which matters for installations exposed to high humidity or extreme climate conditions.
Is WINAICO a Tier 1 manufacturer, and where are the WST-NCX48-AW panels made?
WINAICO is a Tier 1 manufacturer headquartered in Taiwan, meeting strict criteria for financial stability, production capacity, and quality set by independent solar industry rating agencies. Tier 1 status matters for project financing and insurance terms, as banks and insurers often require components from this category to secure more favorable conditions.
What is the maximum power and dimensions of the WST-NCX48-AW panel, and is it suitable for pitched roofs?
The top variant of the series reaches up to 470 Wp with dimensions of 1762 x 1134 x 35 mm and a weight of about 25 kg, standard for glass-glass modules intended for residential rooftop installations. The panel can be mounted on typical pitched roof structures using standard mounting systems, while maintaining the ventilation clearance recommended for bifacial modules to fully utilize their energy potential.
