Singapore saw its fastest solar expansion since 2021, adding over 500 MW in 2025, according to the EMA
The residential segment is responsible for the lion’s share in the cumulative analysis, showing broad adoption across sectors
Growth continues across quarters, according to the data, showing increasing adoption of solar energy across sectors
Singapore has reported its highest annual solar PV installations since 2021, deploying 504 MW in 2025. This represents a nearly 27% year-on-year (YoY) increase over the 397 MW the country added in the previous year. In 2023, the country deployed 370 MW.
Last year’s record installations included the 130 MW addition in Q4 2025, having gone up from 123 MW in the previous quarter, and from 155 MW in Q4 2024, according to the Singapore Solar Photovoltaic Report Q4 2025.
The country’s Energy Market Authority (EMA) says during the last quarter of 2025, 899 new grid-connected solar PV systems were installed, bringing the cumulative installed units to 14,625.
The bulk of this capacity was installed in the residential segment, with 6,912 installations, accounting for 47.3% of the cumulative. Another 5,061, or 34.6%, of installations are installed by town councils and public housing common services, while 2,321, or 2.3% of the total, are in the private segment.
At present, however, the city-state is highly dependent on energy imports since 95% of its electricity comes from imported natural gas. It then remains vulnerable to price fluctuations and international supply. The government admits that the crisis in the Middle East will raise electricity and town gas prices in the country, including retail contracts.
Singapore had targeted 2 GW of cumulative installed PV capacity by 2030, but it reached the target well ahead of time in 2025. It now seeks to scale up the capacity to 3 GW by the end of this decade (see Singapore Raises 2030 Solar Target To 3 GW After Hitting 2 GW Early).
Its solar potential is much higher, according to GlobalData, which forecasts Singapore’s installed solar capacity to rise to about 3.6 GW by 2030 and reach 5.33 GW by 2035.
Rystad Energy also sees Singapore as central to an expected 25 GW of renewable energy and energy storage capacity that can be realized in Southeast Asia if all proposed regional interconnections to the country are realized (see Singapore Interconnectors Could Unblock 25 GW Of Renewable Energy).
