Thinking of switching to solar energy in Singapore? With electricity prices rising and solar panel costs falling, it’s now one of the smartest long-term investments for homeowners. This guide breaks down how much it costs, how solar works in Singapore, and how to get it installed — even if you live in a landed house, condo, or HDB flat.
Why Go Solar in Singapore?
✅ Cut Your Electricity Bills
Rooftop solar panels generate free electricity during the day, reducing your reliance on the grid. On average, homeowners can save up to 20% off their monthly electricity bills — and in some cases, pay $0/month if they produce more than they consume.
Thanks to Singapore’s strong sunlight, a properly installed system can pay for itself in 6 to 8 years, with panels lasting 25 years or more.
Solar Panel Cost in Singapore
A typical home solar panel system in Singapore costs S$15,000 to S$38,000, depending on system size.
| System Size | Estimated Cost | Cost per kWp |
|---|---|---|
| 5–10 kWp | S$15,000–S$20,000 | ~S$2,000/kWp |
| 10–15 kWp | S$20,000–S$30,000+ | Lower per kWp |
| Commercial | ~S$940/kWp | Industrial scale |

Maintenance cost: ranges from S$300–S$500 per visit, but panels are generally low-maintenance.
Installation: What You Need to Know
✔️ For Landed Property Owners
You have full control to install solar panels on your rooftop. We offer free site surveys to check your roof size, sunlight exposure, and give a customised quote. No steep angles needed — Singapore’s location means a simple 5–10° tilt is enough for maximum power.

✔️ For Condo and MCST Properties
- You’ll need approval from the MCST (Management Corporation).
- You can’t sell excess energy to the grid.
- Treated as a “hobby” setup — you may be liable for damages if anything happens.
Tip: If you’re a penthouse or landed MCST owner, you’re more likely to get approval than regular unit owners.
❌ For HDB Flats
Individual unit owners cannot install solar panels on HDB rooftops. However, the government is rolling out solar systems across estates under the Green Towns Programme. Expect 540 MWp of solar capacity by 2030 to support common area power.
Do I Need a Battery?
No, you don’t need one. Most systems in Singapore are grid-tied. Here’s how it works:
- Day: Your home uses solar power first.
- Extra usage? The system taps electricity from the grid.
- Night: You use grid electricity as normal.
Batteries are optional and expensive (S$10k–S$20k extra), so most users skip them. However, you can future-proof with a battery-ready inverter.
Warranties
| Component | Warranty Period |
|---|---|
| Solar Panels | 25 years (power output) + 12 years (product) |
| Inverters | 5 years (standard, extendable) |
Labour charges for repairs may still apply even under warranty, depending on the installer.
Final Thoughts
Solar energy in Singapore is cheaper, cleaner, and more accessible than ever before. Whether you own a landed house or a penthouse unit, installing solar panels can reduce your bills, raise your property’s value, and protect the environment.

Frequently Asked Questions (FAQ) About Solar Panels in Singapore
1. What is the average cost of solar panels in Singapore?
The average cost for a typical landed residential solar panel system in Singapore is around S$20,000 for a 10 kWp setup.
Smaller systems may start from S$15,000, while larger or premium setups can cost up to S$38,000.
2. Can I really reduce my electricity bill to $0?
Yes — but it depends on your energy consumption and system size. If your solar system produces more energy than your home uses during the day, and you’re conservative with electricity at night, your net monthly bill can be as low as $0.
Some homeowners even earn credits by exporting excess electricity back to the grid under the Enhanced Central Intermediary Scheme (ECIS).
3. Do I need approval to install solar panels on my property?
- Landed homes: No approval needed from authorities, but your solar contractor will handle compliance with SP Group and EMA regulations.
- Condos/MCST: Yes, you must get permission from the Management Corporation (MCST).
- HDB flats: Personal installation is not allowed.
4. How do I maintain my solar panels in Singapore’s climate?
Singapore’s frequent rain helps clean panels naturally. However, to maintain maximum efficiency:
- Schedule cleaning once a year
- Check system performance using the inverter app or monitoring dashboard
- Maintenance costs are around S$300–S$500 per visit, depending on system size
5. Are there financing or payment plans for solar installation?
Some providers offer zero upfront cost or monthly instalment plans bundled with your electricity bill. These help homeowners adopt solar without paying the full S$15k–S$30k upfront. Ask your installer if such packages are available.
6. What’s the difference between battery and non-battery systems?
- Non-battery/grid-tied: Most common and cost-effective. Use solar in the day, draw from the grid at night.
- Battery system: Lets you store energy for backup use, but adds S$10,000–S$20,000 to your system cost.
Currently, most Singapore homes don’t use batteries unless they want blackout protection.
