Caodaili PV Project, Dangjin
Powering High-Efficiency Mountain Transformation Benchmark in South Korea
In Dangjin, South Korea, a region of ancient farming traditions, quiet coastal villages, and a landscape dominated by mountains, farmers have long worked the sun-drenched slopes, regarding sunlight as their most valuable harvest. The 5.4MW Caodaili Mountain PV Project was built as a benchmark under these for such scenarios, confronting South Korea’s land shortage and mountainous terrain challenges, and standing as a high-efficiency flagship for AIKO ABC in Korean mountain utility-scale projects. Witness AIKO ABC unlocks the full potential of every ray among the hills, draping this ancient mountain city in “photovoltaic armor.”

Project Challenges
As South Korea’s complex mountainous terrain and scarce, high-cost land resources, the core challenge of the regional “green power” upgrade is to maximize installed capacity and power generation revenue in rugged, heavily shaded environments with limited sunshine duration. Fluctuating mountain operating conditions put forward higher requirements for modules fire safety performance, resistant to micro-cracks, resistant to hot spot and partial shading optimization capabilities.


Solution
By switching Stellar AIKO-A-GRH66Dw, installed capacity 5.4MW.
Compared with TOPCon modules of the same form factor, AIKO N-type ABC modules offer a power output advantage of over 20W, maximizing installed capacity to address the space constraints in mountainous areas. The modules’ exceptional shading optimization and high-temperature resistance performance enable them to complex external environmental challenges, ensuring stable and long-term power output.
Client
Testimonial
The PV plants we operate in South Korea generally have a design life of over 20 years. Once modules are damaged later by shading or high temperatures, it becomes very difficult to find compatible replacements. Therefore, selecting high-reliability modules right from the project’s initial stage to ensure long-term, stable operation is the critical key to securing lifecycle returns for the plant.
