122,000 solar panels across 10 floating islands — Not Japan or China, but this rising Asian energy superpower

On top of Singapore’s reservoirs, thousands of solar panels come together to form ten floating islands, sparkling in the tropical sun. With 122,000 photovoltaic modules, Singapore is turning its limited land availability into a center of innovation in clean energy. This spectacle is the result of strategic intents, technical partnership, and aspirational goals, evidence that Singapore is positioned to lead the region in energy.

Singapore’s floating islands: Transforming lakes and reservoirs into clean energy hubs

In Singapore, which is highly constrained by land, solar installations on roofs, facades, and land are approaching saturation, leaving little room for further growth. Floating solar panels offer a viable solution to this problem. These panels allow arrays to be put on top of reservoirs and lakes, capturing sunlight while utilizing water surface areas that otherwise would go unused.

One of the projects at the Tengeh Reservoirs covers an enormous area and consists of hundreds of thousands of solar panels arranged amongst several floating “islands.” It is one of the largest inland floating solar systems in the world, converting water surfaces into productive, renewable energy.

An ambitious solar project covering 10 islands and generating power from 122,000 panels

At Tengeh Reservoir, 122,000 solar panels on ten floating islands generate approximately 60 MWp, enough to power Singapore’s five water-facility plants. The panels are mounted on adjustable floats so that water can cool them efficiently, compared to rooftops, while turning the reservoir into an active, innovative center for clean energy.

Meet the two key players making Singapore’s floating solar project a reality

In addition to Tengeh, Singapore is investigating near-shore floating solar. Ocean Sun, which specializes in floating solar membranes, has patented technology designed to withstand more severe conditions (i.e., waves and wind), allowing solar arrays to move from still surface water to seawater.

The technology employs large, circular reinforced membranes to hold solar panels, reducing materials used and enabling deployment in lesser-protected, harsher waters, thereby broadening the possibilities of solar floating islands beyond just calm reservoirs.

Keppel Infrastructure is trialing a near-shore floating PV system through its subsidiary near Jurong Island, Singapore’s industrial district. Using Ocean Sun’s membrane technology, the project features three circular floating platforms that produce around 1.5 MWp in seawater whilst demonstrating the potential of coastal solar installations in a resilient operating environment, like this groundbreaking hydropower innovation by the U.S.

Keppel’s responsibility is to integrate these innovations across Singapore’s waters, converting underused sea space into renewable energy real estate.

How Singapore is positioning itself as a leading hub for renewable energy innovation

Floating solar in Singapore is more than just another solar farm; it demonstrates how countries with limited land can creatively source clean energy. With 122,000 panels on beautiful inland reservoirs and near-shore floating solar pilots led by companies Ocean Sun and Keppel, Singapore’s floating solar strategy is evolving from niche demonstration to strategic, scalable infrastructure.

Singapore showcases how limited land can be mitigated with innovative uses of water surfaces, through both a reservoir and a near-shore project. Challenges still exist in maintaining flowing systems, durability with rough waters, integrating into the power grid, and competing with solar costs. The speed with which scaling occurs will determine if others will follow.

If floating solar becomes mainstream in Singapore, in ten years, there could be dozens of, or perhaps hundreds of, floating islands delivering renewable energy to water treatment facilities, industrial applications, and residential areas.

In land-tight Singapore, solar panels are on the rise, not just on rooftops, but also floating on water. This includes both the 122,000 panels at Tengeh Reservoirs and floating near-shore pilots by Ocean Sun and Keppel. Singapore transfers water into energy, demonstrating bold innovations in constrained spaces. The question is whether this model can scale worldwide, just like this Swedish Nova, marking the end of hydrogen.
