NANJING, China, Aug. 20,
2024 /PRNewswire/ -- Grand Sunergy, a leading company
specializing in the R&D, manufacture, and shipment of
high-efficiency HJT photovoltaic cells and modules, recently saw
the booster station of the CGN Yantai Zhaoyuan 400MW offshore
photovoltaic project successfully energized for the first time.
This key milestone marks the operational readiness of China's first large-scale, pile-fixed
deep-water offshore photovoltaic project, showcasing the company's
pivotal role in advancing solar technology.
The project is in the Laizhou Bay area in the northern part of
Yantai's subordinate county-level city, Zhaoyuan City. It covers a
total planned area of approximately 6.44 square kilometers,
consisting of 121 photovoltaic sub-arrays. The project's AC-side
rated capacity is 400MW, with a designed DC-side installation
capacity of 539.3274MW. It exclusively employs Grand Sunergy's
Seapower Series 210-132 double-sided, double-glass high-efficiency
HJT solar modules.
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.
