Can I Install Solar Panels in My HDB Flat? What Residents in Singapore Need to Know

Solar panels have become a common sight on HDB rooftops across Singapore, especially on newer blocks. For a flat owner looking up at them, the natural question is whether solar panels for their own home could go up there too, and whether the electricity bill would come down as a result.

The panels already up there belong to the whole block, not to any single unit. Plus, in Singapore that rooftop is not yours to build on, so whether you can install solar panels in your HDB or not comes down to who owns the roof.

Solar Panels in Singapore: Why Your Property Type Determines Everything

Almost 8 in 10 of the Singapore resident population lives in HDB flats. That single fact shapes how solar energy works here, because the route to solar panels looks completely different depending on whether you own a flat or a landed property, since, as mentioned, access depends on one thing: who owns the roof.

	Landed home	HDB flat
Roof ownership	Common property, Town Council	Owned by the homeowner
Private installation	Not permitted	Permitted
Direct bill savings	Indirect only	Direct, via SCT/ECIS
Approvals needed	HDB / Town Council	EMA and BCA rules only
Solar access	SolarNova and green plans	Own rooftop system

Why Landed Property Owners Can Go Solar

A landed homeowner owns the roof and the exterior of the property outright. No committee vote, no collective approval, no Town Council permission since the roof is theirs to use. That ownership is what makes a private home solar installation possible in the first place.

That ownership brings three advantages:

Exclusive roof ownership: No shared surfaces and no approval chain, so you can engage an installer directly and proceed, with approvals from the BCA and URA needed for some properties.
Usable roof space: A terrace, semi-detached, or bungalow roof gives enough uninterrupted surface to size a system around the household’s actual usage, not a generic average.
Direct bill savings: The system connects to the national grid, and excess energy earns credits under the Simplified Credit Treatment (SCT) or Enhanced Central Intermediary Scheme (ECIS) that offset the electricity bill.

Why HDB Residents Cannot Install Their Own Solar Panels

So can an HDB owner install a solar panel on the roof of their block?

Installing your own solar panels on an HDB block runs into four separate obstacles, and none of them has to do with solar panels themselves.

Shared property: The roof of an HDB block is common property managed by the Town Council. A flat owner owns the interior of the unit, not the walls, corridors, or rooftop. A landed home is the reverse, where the owner owns everything from the roof down.
Safety and structural load: HDB rooftops are already occupied by water tanks, lift motor rooms, and mechanical and electrical equipment. Private panels would add load the roof was not designed for and complicate maintenance access.
Regulation and uniformity: HDB blocks are built to a consistent façade, and grid-tied systems must be fitted by EMA-licensed workers. Modifying shared estate infrastructure without HDB authorisation is not allowed.
A centralised approach works better: Rather than one flat at a time, the government installs solar across whole blocks through SolarNova, reaching thousands of rooftops at a scale no single household could match.

There is also little room to do it inside the unit. While on the shared roof, the decision belongs to the Town Council; inside a flat, a small balcony panel produces too little to be worth it and still needs approval before anything is mounted.

How HDB Residents Still Benefit from Solar Energy

Not owning the roof does not leave HDB residents without solar energy. The benefit comes through two existing channels.

1. The SolarNova Programme

SolarNova is a whole-of-government programme led by HDB and the Economic Development Board (EDB) that pools public-sector demand for solar energy. There are over 10,000 HDB blocks, and the programme has already committed more than 80% of its 540 MWp target for 2030, with panels installed on thousands of blocks and more added in batches. For a resident, it works like this:

Common-area power: HDB solar panels sit on the communal roof and run shared services such as lifts, corridor lights, and water pumps, with any excess fed back to the national grid.
Lower estate costs: The solar offsets what the Town Council pays for electricity, and those savings can flow through to your Service and Conservancy Charges.
Simple to check: Your Town Council can confirm whether your block is already covered.

2. Green Electricity Plans Through the Open Electricity Market

A green electricity plan through a licensed Open Electricity Market retailer is the other route, and it requires nothing on the roof:

How it works: The plan matches your household consumption with Renewable Energy Certificates (RECs), backing your usage with renewable energy without anything being installed.
What it involves: No installation, no approval, no modification to the flat.
Who it suits: A flat owner who wants to support Singapore’s clean energy transition with the least friction.

Are Newer HDB BTO Flats Designed with Solar in Mind?

New BTO developments are in a different category. Since 2020, HDB has built new projects solar-ready, which speeds up SolarNova deployment once a block is due. The solar-ready features include:

Pre-installed rooftop mounting rails and anchor points
Dedicated electrical conduits running from the roof to the electrical rooms
Advanced Metering Infrastructure (AMI) smart meters

New developments are also built to at least BCA Green Mark GoldPLUS, which carries on-site renewable generation targets. For anyone collecting keys to a new BTO, the block roof is very likely already scheduled for panels.

The Bottom Line for Landed Homeowners

From the above, it is clear that HDB residents are not left out of the benefits of solar energy. However, the access is indirect: through SolarNova on the common areas and green retail plans on the meter.

Direct generation with full bill savings is a different matter. Putting solar panels on your own home today requires landed ownership.

If you own a terrace, semi-detached, or bungalow, the roof is one of the most underused parts of the property. A properly sized system delivers on three fronts:

Bill savings: Solar panels for your home can cut the electricity bill by up to 80%, depending on usage, system size, and tariff plan.
Grid credits: Excess energy earns credits back through the SCT or ECIS scheme, offsetting what you draw from the grid overnight.
Payback: Typical payback periods may range from six to nine years, depending on usage, tariffs, and system size, after which the system keeps generating for the rest of its working life.

FOMO Energy builds rooftop solar for landed homes in Singapore, with in-house teams handling design, installation, and after-care. Our Rent-to-Own solar model puts a home solar installation on the roof at S$0 upfront, subject to eligibility, and our REConnect programme covers monitoring and maintenance once the system is running.

For homeowners weighing the numbers, Rent-to-Own solar keeps your capital untouched while the electricity bill starts dropping from the first month. A quick assessment shows the solar panel system size that suits your roof, the savings from the first month, and the point at which the system becomes yours fully.
