Why is Solar Energy Suitable For Harvesting in Singapore

Solar energy emerges as the most promising renewable energy source in Singapore, thanks to the nation’s abundant sunlight. With an average annual solar irradiance of 1,580 kWh/m2/year, Singapore receives about 50% more solar radiation compared to countries in temperate climates. This natural advantage positions solar energy as a reliable and efficient solution to meet the nation’s energy needs while reducing carbon emissions.

Government Targets and Commitments 

In Singapore’s roadmap towards sustainability, one of the key targets is to ramp up the deployment of solar energy significantly. By 2025, the aim is to reach a capacity of at least 1.5 gigawatt-peak (GWp), which is projected to meet around 2% of the nation’s electricity demand. Looking further ahead to 2030, Singapore aims to achieve a capacity of 2 gigawatt-peak (GWp), which could power more than 350,000 households annually, as outlined in the SG Green Plan. These targets underscore Singapore’s commitment to harnessing renewable energy sources for a greener, more sustainable future.

Solar energy is catching on fast in Singapore as people and businesses see how it can change the way we get our electricity. The benefits of solar panels extend beyond reducing carbon emissions; they also offer significant long-term cost savings on energy bills while enhancing energy independence. From solar panels for homes to commercial installations, solar energy adoption is becoming common, driving the nation towards a greener and more sustainable future.

HDB Rooftop Solar Panels

One notable initiative driving solar energy adoption in Singapore is SolarNova, a government-led initiative aimed at installing solar systems on Housing and Development Board (HDB) roofs and public sector buildings. This initiative aligns harmoniously with broader sustainability objectives, including the HDB Green Town Plan, which envisions the installation of solar panels on HDB buildings. SolarNova underscores Singapore’s commitment to integrating renewable energy solutions into its urban landscape, paving the way for a more sustainable future.


Did you know that landed homeowners in Singapore can also install solar in their homes to contribute towards Singapore’s green goals, while saving electricity bills? On average, you can expect about $0.15/kWh if you’re powered on solar! Explore your options when installing a solar pv system.

Solar Panels on Reservoirs and Offshore Lands

Renewable energy companies in Singapore are also making strides in harnessing solar energy beyond traditional rooftop installations. The Sembcorp Tengeh Floating Solar Farm stands as one of the world’s largest inland floating solar PV systems, boasting 122,000 solar panels spread across an area equivalent to about 45 football fields with a capacity of 60 megawatt-peak (MWp). 

Additionally, offshore spaces are being utilised for solar energy generation — projects like Sunseap EDPR’s 5 MWp solar farm at Woodlands, is projected to produce an estimated 6,022,500 kilowatt-hours (kWh) of energy annually.

Solar Panels on Vacant Land

The SolarLand programme, led by JTC, involves the installation of modular solar PV systems on temporary vacant land. Currently implemented on Jurong Island and at Changi Business Park, these solar PV systems represent an innovative approach to leveraging unused spaces for renewable energy generation, contributing to Singapore’s sustainable development goals.

Commercial Buildings

Building Integrated Solar Photovoltaic (BIPV) systems offer a seamless integration of solar PV technology into the design of commercial buildings. Beyond their sustainable benefits, BIPV systems provide visually appealing solutions for clean energy generation, showcasing Singapore’s commitment to sustainable urban development. Furthermore, commercial buildings can explore the adoption of solar panels through power purchase agreements, providing a flexible and cost-effective approach to renewable energy procurement.

Financial Incentives For Solar Energy Adoption in Singapore

To encourage the adoption of solar energy among homeowners and businesses in Singapore, the government offers various financial incentives. These include grants, rebates, and subsidies to offset the initial prices of installing solar panels

Net Metering Scheme

Solar net metering in Singapore is a billing mechanism that credits owners of solar panel systems for the excess energy they generate. While Singapore doesn’t offer a full net metering scheme, consumers can choose to sell surplus solar electricity back to the grid by registering either with SP Services (SPS) or the Energy Market Company (EMC).

There are currently three main schemes: Simplified Credit Treatment Scheme (SCT), Enhanced Central Intermediary Scheme (ECIS) and Market Participant (MP) with the EMC.

Simplified Credit Treatment (SCT) Scheme

  • Only applicable to residential solar panel installations
  • Only applicable to non-contestable consumers (buying from SP Services)
  • Applicable for solar panel systems with less than 1 MWac capacity

SCT compensates you for any surplus energy your solar panels generate at the prevailing tariff rates, deducting grid charges. Grid charges, also known as network costs, usually make up about 20-25% of your electricity tariff. This implies that SPS will reimburse you with approximately 75-80% of the electricity price for the energy you’ve generated. 

For instance, in Q3 2022, with the SP Group tariff at $0.3017 per kWh (before GST), solar homeowners under SP Group would receive $0.2423 per kWh for any excess solar energy injected into the grid.

For homeowners, solar installers can handle the registration for the SCT scheme on their behalf.

Enhanced Central Intermediary Scheme (ECIS)

  • Applicable to both residential and commercial solar installations
  • Applicable to contestable consumers (buying electricity from a retailer of your choice)
  • Applicable for solar panel systems with less than 10 MWac capacity

If you’re a consumer with a solar panel system that has a solar capacity of less than 10 MWac — which should be the vast majority of solar projects — you’ll qualify for the Enhanced Central Intermediary Scheme (ECIS).

Under ECIS, solar energy surplus will be compensated based on half-hourly wholesale energy prices. It’s important to note that wholesale electricity prices can fluctuate based on demand and supply. In the first half of 2022, half-hourly prices ranged from a high of $4.2493/kWh to a low of $0.0876/kWh!

Typically, ECIS is slightly less profitable for long-term excess solar energy sales than the SCT scheme. If your rooftop solar generates much surplus energy, we recommend a switch to SPS for better grid tariff rates. 

Market Participant (MP)

  • Only applicable to commercial solar panel installations
  • Applicable for solar panel systems with more than 10 MWac capacity

Companies with a solar capacity of 1 MWac or higher can opt to directly register with EMC as a Market Participant for electricity sales. In this setup, eligible companies receive payment based on nodal energy prices, determined by energy demand and supply from injection nodes across Singapore.

It’s essential to note that becoming a Market Participant involves substantial upfront costs, primarily suitable for energy companies with multiple assets. These fees comprise a non-refundable one-time registration fee of $5,400 and an annual fee of $10,800.

Renewable Energy Certificates (RECs)

In Singapore, solar owners can also benefit from the sale of Renewable Energy Certificates (RECs), providing an additional financial incentive. RECs are tradable assets representing green electricity generated from renewable sources, allowing solar energy producers in Singapore to derive value from their solar panels. Each REC corresponds to 1MWh of electricity produced by their solar panels.

Corporations without their own solar installations can use RECs to offset their carbon emissions and access sustainable energy sources. By purchasing RECs, these companies gain certified access to solar energy generated by solar producers, facilitating a win-win arrangement. It aids companies in achieving their carbon reduction goals while providing financial support to solar energy producers for maintaining their systems.
