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. ## Notable figures - At 22.6% efficiency, this panel is on par with typical \*\*N-type 550-600W\*\* modules - At 226.5 W/m² power density, roof space requirements are typical for \*\*N-type 550-600W\*\* panels - Temperature coefficient of -0.29%/°C matches the \*\*N-type 550-600W\*\* median - Weight of 32.7 kg is 2.4 kg above \*\*N-type 550-600W\*\* median (30.3 kg) - verify structural support - 80% bifaciality enables rear-side power generation, boosting yield by 4-12% on reflective surfaces ## Questions ### 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. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/WINAICO_WST-585NGX72-A7_AUS_1124_CEC-31a13c80c79c.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [Longi Solar LR7-60HVH-560M](https://comparepv.com/panel/longi-lr7-60hvh-560m) | 560 W | Cooler, lighter, +2.2 pp | | [Longi Solar LR7-60HVH-555M](https://comparepv.com/panel/longi-lr7-60hvh-555m) | 555 W | -30 W, lighter, +2.0 pp | | [AIKO AIKO-A635-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a635-mae72mw) | 635 W | +50 W, lighter, +2.0 pp | | [AIKO AIKO-A630-MAH72Dw](https://comparepv.com/panel/aiko-aiko-a630-mah72dw) | 630 W | +45 W, cooler, +1.8 pp | | [Longi Solar LR7-60HVHL-550M](https://comparepv.com/panel/longi-lr7-60hvhl-550m) | 550 W | -35 W, 16 kg lighter, +1.8 pp | | [AIKO AIKO-A650-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a650-mae72mw) | 650 W | +65 W, lighter, +2.6 pp | | [AIKO AIKO-A645-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a645-mae72mw) | 645 W | +60 W, lighter, +2.4 pp | | [AIKO AIKO-A640-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a640-mae72mw) | 640 W | +55 W, lighter, +2.2 pp | --- Source: https://comparepv.com/panel/winaico-wst-585ngx72-a7 Not in this file, on the page: the I-V and temperature curves lifted from the manufacturer's datasheet, a thirty-year output simulator, a bifacial gain calculator and alternatives filtered by how closely they match these dimensions.
