WINAICO WST-445NCX48-BW 445W N-Type Bifacial Solar Panel
WST-445NCX48-BW | N-Type Bifacial | 96 Monocrystalline Cells | Bifacial | 1500V System Voltage
Product Overview
The WINAICO WST-445NCX48-BW is a high-performance N-Type bifacial solar panel designed for residential and commercial energy systems. This advanced module delivers 445 watts of peak power with an impressive 22.3% efficiency rating. Its bifacial glass-glass construction captures sunlight from both sides, significantly boosting energy yield in low-irradiance environments. The sleek black anodized aluminum frame complements modern architectural designs while ensuring durability. Built with 96 monocrystalline cells wired in 6 strings, it offers superior low-light performance and enhanced electricity production. This WINAICO panel is engineered to withstand extreme weather conditions, making it ideal for diverse global climates. Its lightweight 25 kg design simplifies installation, allowing single-person handling on most roofs. The anti-reflective coating on the front glass maximizes light absorption for optimal power generation.
Key Benefits
Bifacial Energy Gain: Captures sunlight on both front and rear sides, delivering up to 15% additional power compared to standard panels.
N-Type Durability: N-type cells resist degradation better than traditional types, ensuring long-term sustained performance over decades.
Low-Light Efficiency: Enhanced electricity production in cloudy or early morning conditions due to superior spectral sensitivity.
Glass-Glass Construction: Dual 2mm tempered glass layers provide exceptional protection against moisture ingress and physical damage.
30-Year Warranty: Includes both a 30-year product warranty and a 30-year linear performance guarantee for peace of mind.
How It Works
This WINAICO solar panel operates by converting sunlight into electricity through its advanced N-type monocrystalline cells. Unlike standard panels, the bifacial design allows the rear side to absorb reflected light from the ground or surrounding surfaces. This dual-sided absorption increases total energy yield significantly, especially in bright or reflective environments. The anti-reflective coating on the front glass ensures maximum photon entry into the cell structure. When photons strike the cells, they excite electrons to create a flow of direct current electricity. The built-in bypass diodes protect the system from power loss if part of the panel is shaded. This intelligent design ensures consistent performance even under partial shading conditions.
Dual-Side Light Absorption: The front glass captures direct sunlight while the rear glass absorbs reflected light, boosting total power output by up to 15%. This mechanism is particularly effective on white roofs or light-colored ground surfaces.
N-Type Cell Technology: N-type cells use a different doping process that reduces electron recombination losses. This results in higher efficiency and lower degradation rates compared to conventional P-type cells over time.
Bypass Diode Protection: Three integrated bypass diodes isolate shaded sections to prevent them from dragging down the entire panel's output. This ensures the remaining active cells continue generating maximum power efficiently.
