- SDN Company Ltd. is a South Korea-based renewable energy and marine equipment company primarily engaged in the manufacturing, distribution, and engineering of solar photovoltaic systems and marine propulsion solutions. Founded in 1994 and headquartered in Seongnam-si, Gyeonggi-do, South Korea, the company operates across two principal business divisions: the Solar Energy Division and the Engine and Marine Division.
In its Solar Energy Division, SDN Company Ltd. provides comprehensive engineering, procurement, and construction services for turnkey photovoltaic power plants, alongside the manufacture and supply of solar power hardware. The company's core product and service portfolio includes high-efficiency crystalline silicon solar modules; building-integrated photovoltaic systems; ground-mounted, rooftop, and floating solar racking structures; string and central photovoltaic inverters; power conditioning systems; automated solar monitoring and energy management systems; and comprehensive operations, maintenance, and grid-connection engineering services for utility-scale, commercial, and industrial power generation facilities.
In its Engine and Marine Division, the company acts as the authorized domestic distributor of Honda Marine outboard engines in South Korea. The division manufactures and distributes high-performance aluminum leisure boats, commercial fishing vessels, patrol craft, and custom aluminum workboats; four-stroke marine outboard motors ranging across low-to-high horsepower capacities; marine propulsion equipment, spare parts, and steering assemblies; and specialized marine technical inspection, overhaul, and maintenance services for government institutions, commercial maritime enterprises, and recreational watercraft operators.
SDN Company Ltd. serves public institutions, independent power producers, commercial enterprises, and retail marine customers throughout South Korea, while also managing utility-scale renewable power generation assets and engineering operations in international markets, including Eastern Europe and Southeast Asia. The company conducts its project development and asset management activities both directly and through specialized project subsidiaries and overseas project entities.
In recent strategic and operational developments, SDN Company Ltd. has expanded its renewable product pipeline by introducing high-efficiency N-type TOPCon and bifacial solar module solutions tailored for commercial, industrial, and agrivoltaic applications. In its marine business, the company has advanced the development of eco-friendly marine mobility solutions, focusing on electric outboard propulsion systems, hybrid marine powertrain integration, and lightweight recyclable aluminum vessel manufacturing to capitalize on national green shipping modernization initiatives. Additionally, the company has broadened its revenue base by securing expanded long-term operations and maintenance service agreements for domestic solar infrastructure, realigning its overseas project portfolio, and entering strategic collaborations to develop distributed smart micro-grid and energy storage system applications.
