Why solar in Singapore

A rooftop that earns while you work.

Singapore sits near the equator with strong year-round irradiation — and rooftop solar is already the country's biggest renewable resource. Here is what a well-designed system can do for you.

  • Electricity that pays for itself

    At today's panel costs, a well-sized home system can pay back in as little as 5 years, then keep producing for 25+.

  • Cut grid dependence, sell the surplus

    Offset your daytime consumption and export excess generation back to the grid through SP Group.

  • Rooftop is Singapore's solar backbone

    More than 80% of national capacity sits on rooftops — from landed homes to HDB blocks, JTC industrial estates and malls.

  • Green credentials that count

    For businesses: measurable carbon abatement, RECs, and stronger BCA Green Mark and ESG reporting.

How it works

From first survey to live generation.

A four-step path, with SUNLION ENERGY GROUP managing the paperwork so you don't have to.

01

Site survey & design

Roof assessment, shading analysis and a yield model sized to your consumption. You get a clear proposal with expected savings.

1–2 weeks
02

Permits & financing

We submit BCA/URA/SCDF applications and coordinate with SP Group for grid connection. Financing or PPA options arranged.

Paperwork handled
03

Installation

Certified installers mount rails, modules and inverter with full safety protocol. Homes typically take 1–3 days on site.

1–3 days (homes)
04

Activation & monitoring

Commissioning, grid export testing, then 24/7 monitoring via the SUNLION ENERGY GROUP app with annual performance reporting.

What customers say

Quiet roofs, happy owners.

Illustrative quotes from typical projects.

"The whole job took two days, permits included. Our first electricity bill dropped by more than half — the monitoring app makes it easy to see why."

RA
Homeowner, District 1012.4 kWp system

"As facility managers we cared about downtime and safety. SUNLION ENERGY GROUP phased the installation so operations never stopped, and the export revenue shows up in our reports."

KM
Facility manager, Jurong estate486 kWp rooftop

"We chose the PPA route — no capital outlay, and the lease payments are smaller than the electricity we used to buy. Simple decision."

Good questions

Solar in Singapore, demystified.

Short answers grounded in official sources — EMA, MTI and BCA.

For landed homes and most commercial roofs, a permit application through a Qualified Person (covering URA/BCA requirements) is required before installation. SUNLION ENERGY GROUP prepares and submits all paperwork as part of the project — you don't have to deal with the authorities yourself.
With declining panel costs, the payback period for a home solar system can now be as short as about 5 years (EMA, 2025). Typical systems land between 5–9 years depending on roof size, orientation, your consumption and the electricity tariff at the time.
EMA estimates rooftop PV at roughly S$1,000–1,600 per kWp — smaller residential systems sit near the higher end, while large industrial rooftops can approach S$1,000 per kWp. We give a fixed, itemised quote after the site survey.
Yes. Grid-connected systems can export surplus generation through SP Group under the prevailing scheme, and owners can also register and sell renewable energy certificates (RECs) generated by their system.
Very little, but not nothing. Typical operation and maintenance for residential systems runs around 1–2% of system cost per year — periodic panel cleaning, inverter checks and monitoring. SUNLION ENERGY GROUP's maintenance plan covers all of it, with alerts if output drops.
Industry-standard coverage: modules typically carry a 25-year performance warranty (output guaranteed at ~80–85% after 25 years), inverters 5–10 years, and SUNLION ENERGY GROUP adds a 10-year workmanship warranty covering roof penetrations and installation quality.
