Zshine 440W Bifacial Double Glass Monocrystalline PV Module ($0.42/W)

The ZNShine ZXM7-UHLDD108 440W Full Black Solar Panel is a high-performance photovoltaic module designed to maximize energy output while maintaining superior durability and aesthetics. Built with N-Type monocrystalline cells and 16 busbar half-cell technology, the module reduces electrical resistance and increases overall efficiency for improved power generation.

Its bifacial double-glass construction allows the panel to capture sunlight from both the front and rear sides, potentially generating up to 25% additional power depending on installation conditions and ground reflectivity. This design also improves durability and resistance to environmental stress.

With a maximum efficiency of 22.53%, the module ensures optimal performance even in limited installation spaces. The panel also performs well in low-light conditions such as cloudy weather, haze, and early morning sunlight, ensuring consistent energy production throughout the day.

Engineered for long-term reliability, the module includes anti-PID protection, strong mechanical strength, and resistance to harsh environments such as salt, ammonia, humidity, sand, and high temperatures. The full black aesthetic design provides a sleek, modern appearance that blends seamlessly with residential rooftops and commercial installations.

Backed by a 12-year product warranty and a 30-year linear performance guarantee, the ZNShine 440W solar panel offers dependable performance and long-term value for solar energy systems.

The dimension is 1722 × 1134 × 30mm and weighs 24.5±1.0 kg, with a bifaciality factor of 80±10%, allowing it to reliably convert rear-side irradiance into usable power across a range of mounting conditions. Its mechanical design is rated for static loads of up to 5400 Pa on the front and 2400 Pa on the rear, giving it strong resistance to snow, wind, and other structural stresses. Electrically, the module supports a maximum system voltage of 1500V DC and a maximum series fuse rating of 30A, making it compatible with a wide range of string inverter configurations.

Temperature performance is equally well-optimized, with a Pmax coefficient of −0.30±0.03%/°C, a Voc coefficient of −0.25%/°C, and an Isc coefficient of 0.046%/°C, ensuring stable output even as ambient and cell temperatures rise. The module's quality and durability are backed by a comprehensive certification portfolio, including IEC 61215, IEC 61730, IEC 61701, and IEC 62716, along with ISO 9001, ISO 14001, and ISO 45001 management system certifications — reflecting rigorous standards across design qualification, safety, salt-mist corrosion resistance, ammonia resistance, and overall quality, environmental, and occupational health management.
