Frequently Asked Questions (FAQs)

1. Is solar energy worth it in Singapore?

Yes! Despite being a small and urban country, Singapore gets ample sunlight year-round. Solar panels help lower electricity bills, reduce carbon footprints, and may offer up to 30–60% in monthly energy savings, especially for landed homes or high-usage businesses.

2. Can I install solar panels on my HDB flat?

Not directly as a homeowner. Solar installations on HDB rooftops are usually handled by the government or town councils. However, HDB common areas and lifts are increasingly powered by solar energy from large-scale deployments.

3. How much does a residential solar system cost?

A typical 5kWp system for a landed home may cost SGD 10,000 to SGD 15,000, depending on roof size and complexity. Most companies offer financing, grants, or leasing options.

4. What’s the difference between buying and leasing solar?

1. Buying: You own the system, enjoy full savings, and maintain it.
2. Leasing: A solar provider installs the system at no upfront cost. You pay a fixed fee or share the savings. Maintenance is usually included.

5. How long do solar panels last?

Most high-quality panels come with 25-year performance warranties, and inverters typically last 10–15 years. With proper maintenance, systems can last well beyond two decades.
