Singapore-based solar provider Sunseap has announced the completion of an offshore floating solar power plant in the Johor Strait between Singapore and Malaysia. It is one of the world’s largest floating solar power plants on seawater.

One of the first floating solar power plants completed in Singapore

For Singapore, placing a solar power plant on water is not a whim, but a necessity, since the city-state located on the island does not have enough land. But floating solar power plants are usually built in inland water bodies such as reservoirs and lakes. Offshore construction presents specific challenges, including the need to ensure unobstructed passage of ships and control of shell build-up.

The battery, built by Sunseap in about a year (construction delayed due to travel restrictions during the COVID-19 lockdown), has 13,312 panels. They are connected to 40 inverters. It took over 30,000 floats to keep the equipment afloat. The plant is expected to produce approximately 6 GWh of electricity per year. Electricity is transmitted to the shore via a submarine cable. The robust mooring system is said to maintain a constant tension and is able to withstand changing weather conditions, keeping the battery field stable.
