LONGi supplies solar modules for China’s largest 200-meter cargo ship with PV+LNG hybrid propulsion

Frankfurt, Germany, 21.5.25 – LONGi Solar, a global manufacturer for high-efficiency solar modules, has supplied photovoltaic panels for the Yuanhai Kou, China’s largest ocean-going cargo ship equipped with a dual-fuel propulsion system combining solar (PV) and liquefied natural gas (LNG) technologies. The vessel is equipped with over 500 of LONGi’s Sea-Shield modules, engineered with advanced anti-corrosion technology and tailored for durability in harsh marine environments. The modules cover the entire upper deck space of the ship and provide stable clean energy for the vessel’s lighting, communication, and other equipment. The PV system generates 410,000 kWh of electricity annually, saving approximately 111 tons of fuel and reducing carbon dioxide emissions by 345.9 tons, equivalent to planting about 38,000 trees annually (calculated based on a single tree fixing 9 kilograms of carbon per year). The 200-meter-long solar and LNG dual-fuel car carrier has now embarked on its maiden voyage.

Largest photovoltaic system ever installed on a vessel of this class

The "Yuanhai Kou" measures 199.9 meters in total length, with a gross tonnage of 68,252 tons and a displacement of 39,069 tons. It features 12 vehicle decks, including 8 fixed decks and 4 movable decks, with a loading capacity of 7,000 standard car parking spaces. It can carry all types of vehicles such as sedans, engineering vehicles, and buses, as well as MAFI cargo.

As China’s largest PV+LNG-powered car carrier, the Yuanhai Kou features multiple green, low-carbon, and intelligent technologies. In addition to its advanced dual-fuel main engine powered by liquefied natural gas (LNG), the installed PV system provides a peak power of 302.8 kilowatts, which is currently the largest PV system installed on a vessel of its class.

Designed for the demanding conditions of marine environments which are characterized by high salt spray, humidity, and vibration, the Sea-Shield series modules offer enhanced resistance to corrosion and water ingress. This is achieved through the use of anti-corrosion frame materials, reinforced sealing processes, and specially designed junction boxes, ensuring stable and efficient power output in complex shipborne scenarios and supporting reliable green energy generation during navigation.

As a global leader in solar technology, LONGi has continuously developed and introduced purpose-built products tailored to diverse application scenarios. Through an evolving portfolio and solutions aligned with the specific needs of segmented markets, the company plays a key role in driving the industry trend toward differentiated, scenario-based solar technologies.
