Solar Panel Installation for Singapore Landed Homes

RECs (specifically I-REC certificates in Singapore) are tradeable certificates proving that 1 MWh (1,000 kWh) of electricity was generated from renewable sources. As a landed homeowner with solar panels in Singapore, you can generate I-REC certificates for every MWh your system produces. A typical 15 kWp residential system generating 16,500 kWh annually would earn approximately 16-17 I-RECs per year. REC prices vary with market conditions but typically trade at S$2-S$5 per certificate. Rezeca offers a full REC management service—handling all registration with I-REC Standard, monthly tracking, and annual submission to buyers—in exchange for a servicing package, with zero administration work for homeowners.

Solar PV systems require minimal servicing as there are no moving parts. Recommended servicing schedule: (1) Panel cleaning every 6-12 months to remove dust, pollen, and urban pollution that can reduce output by 5-15%, (2) Annual system inspection including electrical connections, inverter diagnostics, and mounting structure checks, (3) Inverter replacement every 10-15 years as inverters have shorter lifespans than panels. Rezeca provides 2 years of complimentary servicing including panel cleaning, system inspections, and performance monitoring via smartphone app.

Yes. Solar panels generate electricity even in diffuse light conditions during cloudy or rainy weather. Singapore's near-equatorial position (1.3°N latitude) means consistent solar irradiance throughout the year with an average of 3-4 peak sun hours daily, even during the monsoon season. While energy output is reduced on overcast days compared to clear sunny days (typically 10-25% of peak output), panels continue producing electricity. Singapore's average annual solar yield is approximately 1,100 kWh per kWp installed, factoring in all weather conditions.

On-site solar installation takes 1–2 weeks for most residential properties. The full process from initial consultation to system commissioning typically takes 8–10 weeks, including regulatory approvals and SP Group grid connection, accounting for: (1) Site assessment and system design (1 week), (2) Regulatory approvals from SP Group and EMA (3-5 weeks), (3) Physical installation (2-5 days), and (4) Commissioning and meter installation (3-5 days).

Grid-connected solar systems in Singapore require approval from: (1) SP Group for grid connection and bi-directional meter installation, (2) Grid-connected residential solar systems require approval from: (1) SP Group for grid connection and bi-directional meter installation, (2) a Licensed Electrical Worker (LEW) for electrical design and commissioning, and (3) URA and BCA depending on the property. Rezeca handles every submission on your behalf, (3) Urban Redevelopment Authority (URA) for certain conservation areas or protected buildings, and (4) Building and Construction Authority (BCA) for structural works if required. All electrical work must be carried out by a Licensed Electrical Worker (LEW). Rezeca handles every submission on your behalf—you don't touch any paperwork. The approval process typically takes 3-5 weeks.

Yes. As of 2026, homeowners export surplus solar power to SP Group at approximately S$0.20/kWh under the Simplified Credit Treatment (SCT) scheme (rate revised quarterly by SP Group). A bi-directional smart meter is installed as part of the solar system commissioning to track both electricity import from the grid and export to the grid automatically. The export credit appears as a reduction on your monthly SP Group electricity bill.

Most residential customers achieve payback in 3–6 years. High daytime electricity users can break even in 3–4 years. After payback, you generate essentially free electricity for 20+ years. After payback, systems generate free electricity for 25-27+ years of the 30-year warranty period. High-consumption households with large roof areas can achieve 2.5-3 year payback. Factors affecting payback include system size, roof orientation, household consumption patterns, SP Group tariff rates (S$0.2911/kWh retail in 2026), and export rates (S$0.2046/kWh in 2026).

Solar panel installation in Singapore starts from approximately S$1,200 per kWp for larger residential landed-home systems in 2026. A typical 10–30 kWp landed home system runs S$15,000–S$45,000, depending on system size, roof type, and equipment selected. Smaller systems carry a higher per-kWp price due to fixed setup costs spread across less capacity. Commercial and industrial rooftops benefit from further pricing efficiency at scale.
