Commercial and industrial solar
Commercial and Industrial Solar for Singapore Businesses
Turn an idle rooftop into lower operating costs and measurable clean energy. We take commercial solar from feasibility and permits to installation, monitoring and maintenance.
Who it is for
Rooftops that suit commercial solar
The best candidates have large, unshaded roofs and use most of their electricity in daylight hours.
Factories
Warehouses and logistics
Offices, showrooms and retail
Condominiums and campuses
Feasibility
From feasibility study to commissioning
- 01
Load profile
We review your electricity bills and interval data to size the system to your daytime demand. - 02
Roof and structure
Our Qualified Person, usually a professional engineer, checks the roof structure and designs the mounting. - 03
Proposal
System size, layout, expected generation, price and payback, with the assumptions stated. - 04
Permits
The QP obtains the permits your building needs, which can include BCA, URA and SCDF (EMA). - 05
Installation and connection
Installed around your operations, then commissioned by our Licensed Electrical Worker and connected to the grid. - 06
Licensing for large systems
Systems of 1 MWac and above may need an EMA Generation Licence and registration with the Energy Market Company. We flag this at feasibility.

Pricing
Commercial solar cost
Your price
From S$1,280 per kWp
For context, EMA puts typical upfront costs at S$1,000 to S$1,600 per kWp, with maintenance of about 1% to 2% of the system cost a year. We quote after the feasibility review, because commercial prices depend on:
- System size and roof area
- Roof type and any structural strengthening
- Cable routes, inverter rooms and switchgear
- Access, lifting and working around operations
- Permits and licensing for the system size
Buy outright
You own the system and every unit it generates from day one. EMA says most consumers break even in about seven years, and that larger systems and higher electricity use can shorten that.
Exporting surplus
How businesses are paid for exported solar
Weekends, holidays and shutdowns mean surplus. EMA sets out three ways to handle it.
Simplified Credit Treatment
Enhanced Central Intermediary Scheme
Non-exporting facility
Source: EMA solar payment schemes. We do not quote a fixed export rate because it changes every quarter.
Sustainability
Solar and Singapore's clean energy target
Every kWh your system generates and uses on site is electricity you did not buy from the grid.
Rooftop solar also contributes to Singapore's national target, which EMA has raised to 3 gigawatt-peak by 2030 after reaching 2 GWp ahead of schedule.
Solar and EV charging
Power your fleet and car park chargers with solar
We install both solar and EV charging, so the array, the chargers and the energy management that connects them are designed as one system. Chargers that run during the day draw on your solar first, which raises the share of generation you use on site.
See our commercial and DC fast charging service, and the OCPP charging management platform we use to run chargers, billing and access.
Operations and maintenance
Operations and maintenance for commercial solar
Inspection and cleaning
Regular visual checks and panel cleaning to keep output up.
Back-end monitoring
Generation watched against expectations, so faults are caught early.
Electrical safety checks
Inverters, isolators and cabling tested and kept compliant.
Vegetation management
Keeping growth and debris clear of the array.
This is the scope EMA recommends. Read more about our solar maintenance and inspection service.

FAQ
Commercial solar questions
How much does commercial rooftop solar cost per kWp in Singapore?
EMA puts typical upfront costs at S$1,000 to S$1,600 per kilowatt-peak (kWp), with yearly maintenance of about 1% to 2% of the system cost. Commercial prices depend on system size, roof type, structural work, cable routes and the electrical connection, so we quote after a feasibility review of your site.
Can we finance the system instead of paying upfront?
We do not offer leases or instalment plans. Systems are bought outright, so you own the system and every unit it generates from day one.
What is the payback period for a factory or warehouse system?
EMA says "most consumers are likely to break even in about seven years", and that larger systems and higher electricity use can shorten that. Businesses that use most of their electricity during daylight hours consume more of their own generation, which is where solar earns the most. We model your payback from your actual load profile.
Is our roof structurally suitable, and who certifies it?
A Qualified Person, usually a professional engineer, checks the roof structure and designs the mounting. Reinforced concrete roofs can take ballasted or penetrating mounts, and metal seam roofs can use clamps that need no drilling. The QP also makes sure the layout meets SCDF fire-safety requirements.
What approvals does a commercial solar system need?
A Qualified Person obtains the permits the project needs, which can include BCA, URA and SCDF. A Licensed Electrical Worker commissions the system and applies for the electrical licences. Systems of 1 MWac and above may also need a Generation Licence from EMA and registration with the Energy Market Company.
How do businesses get paid for exported solar?
It depends on who you buy electricity from. SP Group customers with less than 1 MWac of solar can be credited under the Simplified Credit Treatment, at the regulated tariff minus grid charges, revised quarterly. Customers of an electricity retailer with less than 10 MWac can be paid under the Enhanced Central Intermediary Scheme at wholesale prices. If you do not want to export, you can register as a non-exporting facility instead.
Can solar power our EV chargers or fleet depot?
Yes. We install both, so the solar system, the chargers and the energy management that connects them are designed together. Chargers that run during the day use your solar generation first.
What maintenance does a commercial solar system need?
EMA lists regular inspection and cleaning, back-end monitoring, electrical safety checks and vegetation management, and estimates maintenance at about 1% to 2% of the system cost a year. We offer ongoing maintenance and monitoring support for the systems we install.
