Solar Energy

Solar energy is Singapore’s most viable source of domestic renewable energy. However, it can only meet up to 10% of our projected electricity demand in 2050.

About Solar Energy

Solar energy is harnessed from the sun's radiation and is converted to electrical energy to power electrical appliances. This is made possible using photovoltaic (PV) systems.

Located near the equator, Singapore is one of the most solar-dense cities in the world. We enjoy relatively high solar irradiance of an average annual solar irradiance of 1,580 kWh/m2/year. 

Singapore has achieved our 2025 target of deploying 1.5 gigawatt-peak of solar. We are also on track to meeting our target of at least 2 GWp by 2030, which is equivalent to the annual electricity needs of around 350,000 households. In the longer term, solar will allow us to meet about 10% of our projected electricity demand in 2050.

We will continue to maximise deployment opportunities for solar energy and are also stepping up deployment of energy storage systems to manage solar intermittency.
