Deployment Overview
The Mengxi Blue Ocean Photovoltaic Power Station, built on a coal mining subsidence area, is the largest of its kind. The facility employs a solar tracking system designed to optimize energy production while accommodating the irregular terrain of the site. The system supports real-time adjustments to tracker tilt and can operate in wind speeds up to 18m/s, contributing to consistent energy generation.
Arctech’s Skywings Design for Terrain Adaptability
The tracking system includes features to address the site’s topographical challenges. These include tolerances for undulations of 20% east-west and 15% north-south, as well as customized post heights to maximize space beneath the panels. This design allows for agrivoltaic applications, such as crop cultivation and livestock grazing beneath the solar panels.
Environmental Considerations
The project aims to minimize environmental impact during construction and operation. It employs H-shaped steel piles and static pressure construction techniques to protect the grassland ecosystem. After 25 years of operation, approximately 90% of the steel pipe piles can be recycled, reducing waste discharge by 60% compared to conventional concrete piles.
Projected Energy Output and Emissions Reductions
The facility is expected to produce 5.7 billion kilowatt-hours annually, providing electricity for approximately two million households. It is also projected to save 1.71 million tons of coal annually and reduce 4.7 million tons of carbon dioxide emissions, with the environmental benefit equivalent to planting 62,700 hectares of trees.
