The WST-NGX72-A7 series consists of bifacial glass-glass modules engineered for utility-scale installations where maximizing energy yield per square meter truly matters. The use of N-type monocrystalline cells in bifacial design captures light reflected from the ground surface, translating into real production gains without expanding the installation's footprint. The symmetrical construction, with tempered glass on both sides of the cells, delivers strong resistance to PID and LID degradation, allowing the modules to maintain stable output over many years of operation, even in demanding climates. This build significantly reduces microcracking and corrosion, common issues in cheaper backsheet panels. The series also stands out for improved performance under low-irradiance conditions, a key advantage in regions with variable sunlight such as Poland. With an extended product warranty and a linear performance warranty, investors gain confidence in low lifetime operating costs reflected in LCOE across the system's service life. This is a solution built for solar farm developers and commercial investors who prioritize durability, predictability, and maximum return on investment over the lowest purchase price alone.

About the WST-NGX72-A7 Series series

6 answered

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

How do N-type cells in WINAICO WST-NGX72-A7 panels differ from standard P-type cells?
N-type cells contain less boron and are less prone to LID and PID degradation than conventional P-type cells. As a result, the WST-NGX72-A7 series maintains higher performance over the long term, with a smaller power drop in the first years of operation, which directly translates into higher energy yield over the system's full lifetime.
What is the maximum power output of the WINAICO WST-NGX72-A7 panel and what installations is it suited for?
Modules in the WST-NGX72-A7 series reach a maximum power of up to 585 Wp. This high unit power combined with bifacial technology makes these panels especially cost-effective for large commercial installations and utility-scale solar farms, where maximizing energy yield per square meter of roof or ground area is critical.
How much extra energy do WINAICO WST-NGX72-A7 bifacial panels generate compared to monofacial panels?
The exact gain depends on ground albedo, mounting height, and tilt angle, but under typical conditions these bifacial modules produce noticeably more energy than monofacial panels of the same rated power by capturing light reflected off bright surfaces such as gravel, roofing membrane, or snow. The gain is largest with east-west racking or elevated mounting above the ground.
What warranty comes with WINAICO WST-NGX72-A7 panels?
The WST-NGX72-A7 series includes a 15-year product warranty and a 30-year linear power output warranty. This extended coverage lowers the levelized cost of energy (LCOE) over the full lifetime of the system, which is an important factor for commercial investors planning long-term returns.
Is the glass-glass construction in WINAICO WST-NGX72-A7 panels more durable than standard backsheet panels?
Yes, the symmetrical design with tempered glass on both sides of the cells significantly reduces the risk of microcracks, corrosion, and PID or LID degradation, which are common issues in cheaper backsheet panels. This allows the modules to maintain stable performance for many years, even under harsh climate conditions such as large temperature swings or high humidity.
Is WINAICO a tier 1 manufacturer, and where is the WST-NGX72-A7 series produced?
WINAICO is headquartered in Taiwan and is classified as a tier 1 manufacturer, reflecting financial stability and long-standing experience in photovoltaic module production. This status gives investors greater confidence in warranty service availability and component quality compared to lower-tier manufacturers.
