Solar Panel Installation for Singapore Landed Homes

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. Our landed solar installation starts from S$1,500 per kWp. Typical systems are 10.8 kWp, 15.3 kWp or 20.25 kWp, and you get a fixed, written price after a site survey. The final price depends on your roof type, usable area, system size and any structural or electrical work needed.

It depends less on the house type than on the usable roof area, the direction and pitch of each roof face, shading from neighbours and trees, and how much electricity you use. As a guide, our 10.8 kWp plan needs about 65 m² of roof, 15.3 kWp about 90 m² and 20.25 kWp about 120 m². The free roof report gives a first estimate for your roof, and a site survey confirms it.

EMA says "most consumers are likely to break even in about seven years", and that larger systems and higher electricity use can shorten that. Homes that use more of their own solar during the day, for example by charging an EV at home, get more value from each unit generated.

Yes, but you do not file it yourself. A Qualified Person (a registered architect or professional engineer) oversees the design and obtains the permits the project needs, which can include BCA for structure, URA for planning and SCDF for fire safety. A Licensed Electrical Worker (LEW) then commissions the system, applies for the electrical licences and completes the connection with SP Group. We coordinate all of it.

Yes. If you buy electricity from SP Group, your exported solar is credited to your monthly bill under SP Group's Simplified Credit Treatment, at the regulated tariff minus grid charges. That rate is revised every quarter, so we do not quote a fixed figure. If you buy from an electricity retailer instead, exports are paid under the Enhanced Central Intermediary Scheme at wholesale prices. We register the right scheme for you.

EMA says a landed home installation "usually takes 1-2 weeks, which is also dependent on weather conditions". The survey, design and permits come before that, and we give you a dated schedule once your design is approved.

Panels produce less under heavy cloud or haze and nothing at night. A grid-connected system switches to SP Group power automatically whenever your panels are not covering your use, so the lights never notice. A battery is not required. If you may want one later, we can design the system to be battery-ready.

Solar panels carry the manufacturer's (factory) warranty of up to 20 years, inverters carry the manufacturer's warranty of up to 5 years depending on the model, and our workmanship is warranted for 1 year. Our quotation states each warranty for your system in writing.

No. HDB rooftops are common property, and HDB installs solar on them under the government's SolarNova programme to power common services. We install solar for landed homes, condominiums (through their MCST) and businesses.
