Arctech's SkyWings Empowers the World's Largest Single-Capacity PV Power Plant Built on Coal Mining Subsidence Area

Moreover, to better accommodate the irregular and undulating topography of the plant, Arctech provided a customized SkyWings solar tracking solution that incorporates terrain following capabilities. The tolerance for undulation between adjacent rows is set at 20% in the east-west direction and 15% in the north-south direction. Additionally, Arctech tailored the design of post height to maximize space beneath the solar panels, facilitating agrivoltaics practices. Consequently, farmers are now able to cultivate crops and raise livestock underneath solar panels, achieving both economic and ecological benefits.

To mitigate pollution and ecological damage to the grassland during both construction and operation, SkyWings employs one-piece H-shaped steel piles, while the construction team utilizes on-site static pressure construction. Moreover, following 25 years of safe power station operation, approximately 90% of the steel pipe piles of SkyWings remain suitable for recycling purposes, thereby reducing waste discharge by around 60% compared to traditional concrete piles.

Upon operation, this plant is expected to generate 5.7 billion kilowatt-hours of electricity annually, sufficient to power two million households. Each year, it can save 1.71 million tons of standard coal and reduce carbon dioxide emissions by about 4.7 million tons — equivalent to planting 62,700 hectares of trees.

The utilization of Arctech's SkyWings in this plant further demonstrates its versatility as a solar tracking system capable of adapting to diverse scenarios, including agrivoltaics, irregular terrains, coal mining subsidence areas, and more.
