Located near Dangjin on South Korea’s west coast, the 100 MW solar park spans around 990,000 square metres of reclaimed salt marsh within a protected bird sanctuary. Tens of thousands of migratory birds overwinter at the site each year. To safeguard this sensitive habitat, planners were required to observe a construction freeze from December to February during the main migration season.

Outside this period, installation was carried out as carefully and efficiently as possible to minimise disruption to wildlife. For example, piles were driven using low-noise methods wherever feasible.
Three and half months construction time
Despite these restrictions, the mounting system was installed on schedule between November 2024 and May 2025, with only three and a half months of active construction. The continued presence of migratory birds during and after the work reflects the success of protective measures. “This project shows that even the most demanding PV systems can be implemented on schedule with precise technology, efficient logistics and good cooperation on site,” says James Kim, Managing Director of Schletter Korea. The return of the birds after construction also underlines the ecological success of the project.
Protecting solar plants in extreme weather
The Schletter FS Duo SRF6 mounting system was used in combination with ETA2 and LC90 pile foundations. It was specifically developed to meet the structural and corrosion challenges of coastal environments. “Dangjin presented us with extreme conditions – from strong coastal winds and high salt exposure to unstable ground and strict environmental regulations,” says James Kim, Managing Director of Schletter Korea. “Our FS Duo system was chosen not only for its ease of assembly, but also because it significantly exceeded all local requirements for structural stability and traceability.”
Expanding involvment also in small and medium-sized PV
The client was Korean energy company SK E&S, with Hanwha Solutions responsible for construction and implementation as the EPC service provider. With Dangjin, Schletter Korea is realising another major project on the Korean peninsula. The Taean (300 MW) and Seosan (42 MW) projects have already been successfully completed. The company is thereby consolidating its market position in the South Korean PV sector.
Enstall acquires Schletter Group
In parallel with large-scale projects, Schletter Korea is expanding its activities in the small and medium-sized PV segment. The focus is on fast availability, tailored planning support and certified system quality for a wide range of requirements. (hcn)
