Cost Breakdown: Installing Solar Panels for Singapore Landed Homes

Installing solar panels on your landed property in Singapore is a smart move—both financially and environmentally. However, many homeowners hesitate due to the perceived high cost of solar systems. The truth is that the long-term savings often outweigh the initial investment, especially for energy-intensive landed homes. But how much does it really cost to install solar panels? What factors affect the pricing? And what value are you getting for your money?

In this article, we provide a complete cost breakdown of installing solar panels for Singapore landed homes, highlighting the components, pricing ranges, influencing factors, and long-term returns.

1. Average Cost of Solar Installation for Landed Homes

As of 2025, the average cost of a solar panel system for a Singapore landed property ranges from SGD $10,000 to $30,000, depending on system size and complexity. Here’s a basic estimate by system capacity:

Note: Prices vary by contractor, brand, roof type, inverter type, and additional features like monitoring systems or battery integration.

2. Major Cost Components of a Solar System

Let’s break down the key components that make up the cost of a solar panel installation for landed homes in Singapore.

a) Solar Panels (40–50% of total cost)

Solar panels are the most visible part of the system. Higher quality panels (e.g., Tier-1 monocrystalline) offer better efficiency and longer warranties.

• Average cost per panel: $300–$500

• Total panel cost for 5kWp system: $4,000–$6,000

b) Inverters (15–20%)

Inverters convert the direct current (DC) from panels to usable alternating current (AC). You can choose between:

• String Inverters (most cost-effective)

• Microinverters or Optimisers (better shading performance but more expensive)

• Average inverter cost: $1,500–$3,000

c) Mounting System (10–15%)

This includes the brackets, rails, and fasteners used to secure the panels to your roof.

• Costs depend on your roof type (metal, clay tile, concrete) and complexity.

• Estimated cost: $1,000–$2,500

d) Installation Labour (10–15%)

This covers the labour required for mounting, electrical wiring, safety measures, and testing.

• Labour costs in Singapore are relatively high but reflect skilled work.

• Estimated cost: $1,500–$3,000

e) Monitoring System (5%)

Most modern systems come with apps or dashboards that allow you to track energy generation in real-time.

• Optional upgrades include smart meters or home automation integration.

• Estimated cost: $500–$1,000

f) Administrative and Compliance (2–5%)

This includes grid connection applications, EMA licensing, safety approvals, and inspections.

• Usually handled by the contractor.

• Estimated cost: $300–$800

g) Optional: Battery Storage (Highly Variable)

Battery storage allows you to use solar power at night or during outages.

• Brands like Tesla Powerwall or Huawei cost $7,000–$15,000 per unit.

• Not necessary for most landed homes unless you’re seeking energy independence.

3. Factors That Affect Your Solar Installation Cost

Several factors can impact your total installation cost:

a) System Size

Bigger systems cost more upfront but have better economies of scale. If your consumption is high (e.g., >1000 kWh/month), a larger system provides faster ROI.

b) Roof Condition and Complexity

Steep, multi-faceted, or fragile roofs (like clay tiles) require more labour and special mounting systems. This increases cost.

c) Shading and Orientation

If shading is present, your system may require microinverters or optimisers, adding 10–20% to your cost.

d) Electrical Upgrades

Older homes may require distribution board upgrades, rewiring, or safety improvements to handle solar input.

e) Contractor’s Reputation and Service

Premium solar contractors may charge more—but they usually provide better design, components, warranties, and after-sales service.

4. Solar Panel Financing and Payment Options

If upfront cost is a concern, here are some options:

a) Outright Purchase

Best long-term savings and ownership. Full control over the system. Payback typically in 6–10 years.

b) Green Loans

Banks in Singapore offer green renovation loans at lower interest rates for solar panel installations.

c) Solar Leasing (Rare for Landed Homes)

Third-party providers install the system and you pay monthly fees. However, this is more common in commercial or industrial settings.

5. What You Get for the Cost: Long-Term ROI

While solar requires upfront investment, the long-term returns make it worthwhile:

Other benefits include:

• Increased property value

• Environmental impact (reduction in carbon footprint)

• Protection against rising energy prices

6. Comparing Solar Panel Contractors

Here’s a checklist of what to look for when getting quotations:

• Detailed itemised breakdown

• Equipment brands and warranties stated

• Projected energy output and ROI analysis

• Timeline and installation process

• Maintenance plans included

• Licensing and EMA/BCA compliance support

Always get at least 2–3 quotes before proceeding. Don’t just go for the cheapest—balance quality, reliability, and service.

7. Maintenance and Ongoing Costs

Solar panels require minimal maintenance. Typical recurring costs include:

• Cleaning (Optional): $200–$400/year for professional panel cleaning

• System Health Checks: Recommended every 1–2 years

• Inverter Replacement: May need replacing after 10–15 years (approx. $1,500–$2,000)

Your total ongoing costs are relatively low, especially compared to the long-term electricity savings you’ll enjoy.

8. Warranties and Guarantees

When spending $15,000–$30,000, warranties are critical. Ensure you get:

• Performance Warranty: 25 years (e.g., 80–85% efficiency guaranteed)

• Product Warranty: 10–15 years for panels and inverters

• Workmanship Warranty: 5–10 years from the contractor

This gives you peace of mind that the system will perform as promised.

Conclusion: Solar Panels Are a Worthwhile Investment for Landed Homes

While the initial cost of installing solar panels on your landed property in Singapore might seem high, the return on investment, long-term savings, and sustainability benefits make it an increasingly smart decision.

When you understand the full cost breakdown—panels, inverters, labour, warranties, and savings—you’ll see that solar energy is not an expense, but an investment. One that pays off financially and environmentally for decades to come.
