Grand Sunergy Powers China's First Large-Scale Yantai Zhaoyuan 400MW Offshore HJT Solar Project

Due to the harsh marine environment characterized by high humidity, high salt spray, high corrosion, high ultraviolet radiation, lightning surges, low-temperature ice and snow, biological fouling, and thermal shading challenges, offshore photovoltaics differ significantly from onshore photovoltaics. To fully address the complex offshore application environment, Grand Sunergy has conducted targeted technical development and application scenario matching for modules tailored for the unique offshore environment.

The Seapower Series HJT solar modules adopt 210mm large-size HJT cells, double-layer coated glass, UV-resistant encapsulation film, high-resistance water-sealing butyl rubber edge sealing, waterproof/salt spray-resistant junction box, and dust-proof plug/protective cover connectors. These utilize new processes and materials, significantly enhancing the module's resistance to salt spray, corrosion, UV radiation, water vapor, and wind load. This upgrade in weather resistance further strengthens its reliability.

With Grand Sunergy's offshore solar module solution, the Seapower Series are equipped with an additional glass coating layer, enhancing the glass's weather resistance. Light-conversion films convert short-wavelength ultraviolet light into longer-wavelength blue light, increasing the light utilization rate and eliminating power attenuation caused by strong UV light.

Additionally, the edge sealing employs a butyl rubber edge sealing technology, reducing water permeability by 99.9% compared to industry standards. This effectively prevents water vapor from infiltrating the module interior through the double-layer glass, making it highly suitable for hot and humid coastal environments.

The Yantai Zhaoyuan 400MW offshore solar project has strong demonstrative significance and driving effect in the industry, marking an important step forward for China's offshore solar sector.
