Harnessing Solar Energy in Singapore: A Bright Future Ahead
You’ve probably noticed that Singapore is all about going green these days. And with our year-round sunshine, it's no wonder solar energy is the hot topic on everyone's lips. But what exactly is solar energy, and how does it all work?
If you’re curious about how this sunny solution can power your business and boost your green credentials, you’re in the right place. Let’s dive into the radiant world of solar energy in Singapore and see why it’s shining so brightly on the nation’s energy landscape.
What is Solar Energy?
Solar energy is the radiant light and heat we receive from the sun, and it has been harnessed by humans for thousands of years in various ways. Today, with advances in technology, we can efficiently convert this abundant energy into electricity using photovoltaic (PV) systems. These systems are commonly known as solar panels.
How Do Solar Panels Work?
At the core of every solar panel are photovoltaic cells—usually made from semiconductor materials like silicon. Here's how they work:
-
Sunlight hits the cells, specifically the photons (light particles) from the sun.
-
These photons transfer energy to the electrons within the semiconductor, knocking them loose from their atoms. This process is called the photovoltaic effect.
-
The movement of these free electrons creates direct current (DC) electricity.
But because homes and businesses run on alternating current (AC), the DC electricity produced by solar panels needs to be converted. That’s where an inverter comes in, turning DC into AC so the electricity can power your everyday appliances and systems.
To generate more electricity, multiple solar panels can be linked together to form a solar array. These panels work together to capture more sunlight, providing higher energy output. Whether you need to power a small business or a large industrial site, solar arrays can be scaled to meet your specific needs.
In Singapore, solar energy is widely harnessed through these PV systems. The electricity generated can be used directly to power businesses or homes, and any surplus energy can be fed back into the national grid, contributing to the country’s clean energy mix.
What’s the State of Solar Energy in Singapore?
On our little red dot, solar energy isn’t just a buzzword; it’s a critical part of the nation’s strategy to build a greener future. Despite the size of our country, Singapore is making impressive strides in adopting solar technology. Solar panels are increasingly being installed on the rooftops of HDB flats and public sector buildings, maximising every available space to capture the abundant sunlight we receive year-round.
One standout example of Singapore’s solar ambition is the floating solar photovoltaic system at Tengeh Reservoir. Spanning the size of 45 football fields, this 60 megawatt-peak installation is a testament to Singapore's innovative approach to maximising solar energy use, even on water bodies. In fact, Singapore is one of the most solar-dense cities in the world.
The Singapore Green Plan 2030 has set ambitious targets for solar energy. By 2030, the country aims to deploy at least 2 gigawatt-peak of solar energy, which could power approximately 350,000 households annually. However, solar energy's intermittent nature—its reliance on sunlight, which varies with weather—presents a challenge. To address this, Singapore is investing in Energy Storage Systems (ESS) to store excess energy and ensure a stable supply. The recently launched ESS on Jurong Island, the largest in Southeast Asia, is a prime example of this commitment.
Technological Advancements: A Brighter Future
Now that we’ve explored how solar energy is generated, let’s talk about how the technology behind it has seriously levelled up.time to unravel another layer of the sustainability conversation. Let’s delve into the nuanced distinctions and see how RECs stack up against carbon offsets across several crucial factors:
Increased Efficiency
Over the past decade, solar panels have made impressive strides in efficiency. Back in 2014, the average efficiency of commercially available solar panels ranged between 15-17%. Fast forward to today, and we’re seeing average efficiencies of 18–22%, with top-tier panels reaching up to 23%.
That’s a substantial increase of around 20–30% in efficiency over just ten years. Although some cutting-edge solar panels are now achieving more than 40% efficiency, these are not yet commercially available, leaving plenty of room for future advancements.
Lower Costs
Alongside these efficiency gains, the cost of solar panel installation in Singapore and around the world has dropped dramatically. Between 2010 and 2020, the average cost of solar photovoltaic (PV) modules fell by an astonishing 89%. This sharp decline is due to a combination of technological advancements, economies of scale in manufacturing, and increased competition within the solar industry.
Globally, the levelised cost of electricity (LCOE) from utility-scale solar PV has decreased by 85%, making solar energy a cost-competitive alternative to traditional fossil fuels.
Battery Storage
Energy storage solutions, such as advanced batteries, have also made significant strides. These systems allow businesses to store excess solar energy generated during the day for use at night or during periods of high demand. This capability ensures a continuous power supply, even when sunlight is unavailable, enhancing energy security and reducing reliance on the grid.
The development of more efficient and affordable battery systems is enabling businesses in Singapore to achieve greater energy independence, making solar energy an even more attractive option.
Solar Energy for Your Business: Weighing the Pros and Cons
Solar energy is often hailed as the future of clean power, but like any big decision, it's important to look at the full picture. While the benefits are significant, solar energy isn’t without its challenges. Let’s break down the pros and cons so you can see how solar might fit into your business strategy.
Advantages of Using Solar Energy:
-
Reduced electricity bills: Who wouldn’t want to save on electricity costs? By generating your own solar power, you can cut down on your reliance on the grid, which means lower energy bills. And as electricity prices continue to climb, the savings only get better over time. For businesses with high energy demands, this can lead to some serious cost reductions.
-
Government incentives: The Singapore government is pretty keen on getting businesses to go green, and they’re putting their money where their mouth is. Take the Energy Efficiency Grant (EEG), for example—it’s designed to help businesses invest in energy-efficient equipment. With the EEG, you could get up to $30,000 for pre-approved gear, or even more if you’re making a bigger push for energy efficiency.
-
Environmental benefits: Going solar is one of the best ways to show that your business cares about the planet. Solar energy is clean and renewable, which means you’re cutting down on your carbon footprint and doing your part to fight climate change. It’s not just good for the environment—it’s also a great way to boost your brand’s image and appeal to customers who value sustainability.
-
Energy security: Solar energy gives your business a bit of independence from the grid, which can be a real advantage. With your own solar power system, you’re less exposed to the ups and downs of electricity prices and supply issues. That means more stability for your operations, especially during peak demand or in case of grid disruptions. It’s all about keeping your business running smoothly, no matter what.
Disadvantages of Using Solar Energy:
-
Space requirements: Let’s face it, solar panels need space—whether it’s on your roof or a dedicated plot of land. If your business has limited roof or ground space, you might find it challenging to install enough panels to meet your energy needs. This is especially true for urban areas where space is at a premium. It’s something to consider when planning your solar setup.

Your QP will be responsible for ensuring that your solar photovoltaic (PV) system is installed correctly and complies with all relevant regulations.
Depending on your project’s specifics, your QP might need to obtain approvals from various government authorities, such as the Building and Construction Authority (BCA) for structural safety, or the Urban Redevelopment Authority (URA) for planning permission. It’s crucial to have an experienced professional guide you through these steps to avoid any regulatory hiccups.
Building Permit
If your solar panel installation involves significant structural work—like structural strengthening or building a platform higher than 2.5 metres—your QP will need to submit structural and building plans to the BCA via CORENET. The process typically takes 7 to 14 working days for approval.
For installations that cover an area larger than 10 square metres or that also function as a roof shelter, you’ll need to comply with specific building regulations, including lightning protection as outlined in the SS555:2018 Code of Practice.
Grid Construction
Once your solar PV system is physically installed, the next step is getting it connected to the grid. For this, you’ll need to work with a Licensed Electrical Worker (LEW), who will handle the technical aspects, such as applying for the necessary electrical licences and ensuring the system meets SP Group’s connection requirements.
If your solar PV system has a capacity of 1MWac or more, you might also need to apply for a generation licence from the Energy Market Authority (EMA) and register with the Energy Market Company (EMC).
Large Scale Installations
For larger commercial solar installations in Singapore, especially those above 1MWac, additional steps are required. This includes obtaining a generation licence and possibly registering as a Market Participant with the Energy Market Company if you plan to sell excess electricity back to the grid. Your LEW will guide you through these processes, ensuring compliance with all technical and regulatory requirements.
