How Much Do Solar Panels Cost in Singapore? The Complete Breakdown

Solar panel systems in Singapore are gaining popularity as the most viable energy source in the renewable energy transition. Given our limited land space and bright, tropical environment, solar is a suitable energy source on rooftops and even reservoirs.

Solar panels in Singapore is evolving into a more practical cost-saving choice due to the recent energy crisis and increase in electricity bills.

Our comprehensive guide will cover every detail for households thinking about solar!

Benefits of Solar


1. Attractive Electricity Cost Savings

Solar panels are frequently thought of as something that only environmentalists should use. On the contrary, the financial advantages are why many individuals choose solar energy in the first place! Solar energy systems have a minimum 25-year lifetime and are an investment that saves money on power bills.

2. Combat Climate Change

An important problem that is posing a threat to us every day is climate change. We produce more dangerous greenhouse gases and carbon dioxide each year. Solar energy is renewable and does not rely on a finite natural resource, which helps to decarbonize our energy infrastructure.

3. Solar Panel Prices: Lower than ever

In his 2022 May Day Rally speech, PM Lee Hsien Loong discussed the effects of rising energy prices on Singapore and its citizens in his speech. Household power bills will continue to grow as a result of the Russia-Ukraine war, rising electricity consumption, and a shortage of electricity substitutes.

Solar power, on the other hand, is becoming more and more affordable. Did you know that during the past ten years, the cost of solar energy has decreased by 89% worldwide? Although many people believe solar energy is pricey, it is currently the least expensive method of producing power. This is mostly because of cheaper prices and more cost-effective technology as solar energy gains popularity. With all of this in mind, there has never been a better time to start switching to solar and lowering your power costs!

Is it feasible to run a home solely on solar energy?

The size of your solar system and how much power you consume at home will determine this. After switching to solar, some households might really spend $0 a month on power. In fact, on a bright day, you may even produce more power than your home requires and profit by selling the extra to the grid!

In fact, we have a number of testimonies that speak to the viability of powering your home solely with solar panels.

In Singapore, do I need batteries for my solar power system?

Most of the time, no. Since excess solar energy may be sold back into the grid, grid-tied solar panel systems in Singapore are often used and do not require batteries.

When it is sunny outside, your home will initially use the solar energy produced by your system to create electricity. If you use more energy than is produced, the system will automatically pull power from the grid. Your home will continue to draw power from the grid as usual at night when your system is not producing energy, so there won’t be any power outages. The final outcome? You save money on power since you use the grid considerably less.

Installing batteries is typically not advised due to their high cost (they can increase the cost of your system by $10–20,000 at this time). However, building battery-ready inverters will make it simple for you to add batteries later on as prices decline.

In Singapore, can I install solar panels if I purchase my power from an OEM retailer?

You may install solar at any time, regardless of when your OEM retailer contract expires, because installing solar is not contingent on it. Nevertheless, having clients under SP Group may make it administratively simpler for certain solar installers. In order to increase their profits at times when wholesale power prices are higher, solar homeowners who produce more solar energy than they need may even decide to sell their excess solar electricity to an OEM retailer.

Can I install solar panels in a HDB?

Nearly 80% of Singaporeans reside in HDB apartments. Unfortunately, the majority of these people are unable to modify or add solar panels to their HDB roof. But HDB does have its Green Towns Program, which aims to put 540 MWp of solar panels on HDB estates in Singapore by 2030.

If I live in a condo or MCST, am I still allowed to install solar panels?

Condominium buildings are communal living areas, thus it’s likely that there are limits on solar panel installation there. Here are some crucial considerations to keep in mind if you’re the owner of a penthouse or MCST landed home and want to install solar panels:

  • Prior to doing anything, you must receive permission from your condominium management corporation, strata title (MCST)
  • You won’t be able to sell any extra power to the grid or export it.
  • The installed solar system will be viewed as a “hobby” installation, and you could be held responsible for any dangers to the condominium.

Is it possible to install solar panels on a landed home?

Yes! Landed homeowners can easily install solar panels in Singapore.

Are solar panels acceptable for my roof?

The three key elements that determine whether your roof is suitable for solar panels are as follows: Size, Shade Amount, Angle & Direction, and Size.

Solar panels may be installed on most rooftops. Solar panel installations would not be the best choice for roofs that are extremely complicated or shadowed. A smaller system may fit on a smaller roof, which often yields a lesser rate of return on investment.

How much does Solar Panel Cost in Singapore

The cost of installation will vary based on several factors, including the number of solar panels installed. The cost of a solar panel installation in Singapore ranges from S$15,000 to S$38,000 or more. That said, a good estimate will be S$20,000 as most residential solar panel systems are around 10 kWp (S$2,000/kWp). While a 1,000 kWp industrial rooftop PV system can cost around S$940/kWp. Besides the number of solar panels installed, the operation and maintenance costs range between 1 to 1.45% of upfront costs (1% for large rooftop systems compared to 1.45% for smaller systems). For more cost information you can refer to the 2020 “Update to the Solar PV Roadmap for Singapore ” report, the National Solar Repository website or you can simply reach out to us.

Warranty and maintenance for solar panels

Most solar panels have a 25-year power output guarantee in addition to a 12-year product warranty. Solar inverters, meanwhile, often come with a 5-year manufacturer’s guarantee. These warranties often include replacements of any physically flawed equipment on a one-for-one basis.

This implies that even while replacement solar panels will be given at no cost to you if you need them during the warranty term, you could still be responsible for paying your installer’s labor charges for the repair job. Your solar panel system’s maintenance and cleaning expenses in Singapore typically vary from $300 to $500 every visit.
