With the increase in Singapore’s solar deployment target to 3 gigawatt-peak (GWp) by 2030, the Government will be ramping up efforts to deploy solar across more viable surfaces. This includes tapping on all feasible rooftops, land, and water spaces as well as exploring more innovative solar deployments such as overhang solar that could serve as shelters, canopies at open-air car parks, and other suitable areas.

2. Singapore achieved the milestone of 2 GWp of installed solar capacity in 2025. This has been driven by solar installations’ increasing cost-competitiveness and Government-led programmes such as SolarNova by the Housing & Development Board, as well as SolarRoof and SolarLand by JTC on industrial real estate. At present, rooftop solar is estimated to make up more than 80% of the total installed capacity.

3 . Solar deployment by private commercial, industrial and residential users has also been rising. The payback period for home solar power systems has improved to as short as five years due to decline in costs of solar panels. Some solar power vendors also offer solar “rent-to-own” plans that can reduce upfront costs of solar installations. Owners of solar power systems can also sell the renewable energy certificates (RECs) generated from solar energy for additional income.

4. The new solar target of 3 GWp, which is equivalent to powering around half a million households a year, significantly advances Singapore’s transition towards cleaner energy sources. Mr Puah Kok Keong, Chief Executive of the Energy Market Authority, said: “Singapore is already one of the world’s most solar-dense cities, but we can do more. We are committed to maximising opportunities for solar deployment while pursuing other low-carbon energy pathways. Our new solar target reflects Singapore’s commitment to building a cleaner, more resilient energy system. This important initiative requires strong collaboration across government, industry and the community. We look forward to partnering our stakeholders to accelerate solar deployment and support Singapore’s energy transition.”

5. While solar is currently the main source of renewable energy that can be harnessed domestically, it can realistically contribute only up to around 10% of Singapore’s projected energy needs by 2050. With limited domestic energy sources, Singapore will continue to pursue a diversified energy mix to reduce carbon emissions from power generation, while ensuring energy security and the power system’s resilience.
