SDN

SDN runs two distinct businesses: it supplies solar power systems, panels, and inverters for electricity generation, and it distributes outboard motors, small engines mounted on the back of boats, to fishermen, leisure boaters, and government vessel operators.

Its solar division handles the full project lifecycle, from designing and building solar installations to ongoing maintenance, while also producing its own branded panels. Listed on KOSDAQ, Korea's tech and small-cap board, SDN operates both divisions as an integrated solutions provider rather than focusing on a single product.
