Solar panels are a smart long-term investment for landed homeowners in Singapore, offering energy savings, sustainability, and future-proofing benefits. But just like any home system, solar panels require regular care to ensure they continue performing at their best. Neglecting maintenance can lead to reduced efficiency, shorter lifespan, and lower returns on your investment.

In this comprehensive guide, we share practical maintenance tips tailored for landed house owners in Singapore, helping you maximise your solar system’s performance and reliability for the next 25 to 30 years.

1. Why Maintenance Matters for Landed Property Solar Systems

Although solar panels are often described as “low maintenance,” they are not maintenance-free. Over time, dust, bird droppings, debris, and weather exposure can reduce panel efficiency. For landed properties with direct roof access and tree coverage, maintenance becomes even more essential.

Key reasons to maintain your system:

• Maintain high energy output

• Prolong system lifespan

• Detect and fix issues early

• Prevent fire or electrical hazards

• Safeguard your return on investment

2. Understand Your Solar System Components

Before you can properly maintain your system, it’s important to know what you’re working with. A typical landed home solar setup includes:

• Solar panels (PV modules) – capture sunlight

• Inverter – converts DC to AC power

• Mounting system – holds panels to the roof

• Electrical wiring & isolators – connects system to your home

• Monitoring system – tracks performance and issues

Each of these parts plays a crucial role and has its own maintenance needs.

3. Cleaning Solar Panels: How and When

Singapore’s tropical climate means your panels may collect dirt from:

• Rain and dust buildup

• Bird droppings

• Falling leaves from nearby trees

• Air pollution (especially near construction sites)

Recommended Cleaning Frequency:

• 2–4 times a year for standard landed homes

• More frequently if surrounded by foliage or near highways

Cleaning Tips:

• Clean during cool, early morning hours to avoid thermal shock

• Use soft sponges or microfiber cloths

• Use mild detergent with water, avoid abrasive chemicals

• Never use high-pressure hoses, which can damage panels

• Ensure proper safety measures if climbing up yourself

For high or steep roofs, always engage a professional cleaning service.

4. Visual Inspections You Can Do Yourself

A quick monthly or quarterly inspection from ground level can catch issues early.

Look for:

• Discoloration or hot spots on panels

• Loose or frayed wires

• Water pooling or corrosion around mounting brackets

• Bird nests or leaf buildup near panels

• Cracks in glass or broken panel frames

If something doesn’t look right, call your installer or maintenance team immediately.

5. Monitoring System Performance

Most modern solar systems come with a real-time performance monitoring app or portal, allowing you to:

• Track daily and monthly energy generation

• Spot sudden drops in output (which may indicate an issue)

• Compare performance across different panels or strings

• Receive alerts when faults are detected

Make it a habit to check your dashboard weekly or monthly. Sudden dips in output, especially during sunny periods, should prompt a visual inspection or professional diagnosis.

6. Maintaining the Inverter

Your solar inverter is the brain of your system. It’s also the most likely component to need servicing during your system’s life.

Tips for inverter care:

• Check for warning lights or beeping alerts

• Ensure the area around the inverter is dry and well-ventilated

• Clean dust from the surface with a dry cloth every few months

• Monitor the inverter’s performance via the app

Most inverters in Singapore last 8–15 years, so plan for a potential replacement around that time.

7. Dealing with Birds, Leaves, and Wildlife

In landed homes surrounded by trees or gardens, it’s common to encounter:

• Bird nesting under panels

• Squirrels or lizards entering conduit boxes

• Leaves and branches accumulating around mounts

This can lead to:

• Shading and energy loss

• Electrical short circuits

• Panel corrosion from droppings

Prevention methods:

• Install critter guards or mesh netting around panels

• Trim trees to reduce falling debris

• Conduct quarterly inspections, especially during nesting season

8. Waterproofing and Roof Checks

Your roof is the foundation for your entire solar setup. Maintenance must include ensuring roof integrity.

What to check:

• Signs of leakage or water stains inside the attic or top floor ceilings

• Loose mounting brackets

• Rust or corrosion on metal roofs

• Sealant cracks around mounting points

Tip: A good solar contractor will waterproof all roof penetrations and provide leak warranties—make sure this is in your installation agreement.

9. Engaging Professional Solar Maintenance Services

For comprehensive upkeep, consider professional servicing once a year. They typically offer:

• Full system diagnostics

• Panel cleaning

• Roof and structure inspection

• Thermal imaging to detect faulty panels

• Electrical integrity testing

• Inverter firmware updates

This is especially helpful for homeowners who don’t want to climb roofs or handle electrical components.

10. Maintenance Costs for Landed Home Solar Systems

Typical maintenance costs in Singapore:

Some contractors offer free maintenance for 1–3 years after installation.

11. Maintenance Tips During Rainy Season

• Ensure leaves and water don’t pool under panels

• Check for moisture inside junction boxes

• Watch for output drops due to reduced sunlight

• Ensure lightning arrestors and surge protectors are in place

While solar panels are designed to withstand heavy rain, ongoing checks during monsoon periods help prevent long-term water damage.

12. Solar Battery Maintenance (If Applicable)

If your landed home includes a solar battery system, maintenance becomes even more important.

Tips:

• Keep batteries in a cool, dry, ventilated indoor space

• Monitor charge cycles and avoid deep discharges

• Update firmware periodically

• Watch for bloating, heat, or leakage

Most lithium-ion batteries come with 10-year warranties, but care can extend their usable life.

13. Maintenance Do’s and Don’ts

DO
✔ Clean panels gently and regularly
✔ Check the monitoring app weekly
✔ Watch for pests, leaves, and corrosion
✔ Schedule yearly professional inspections
✔ Work with licensed electricians for system checks

DON’T
✘ Use harsh chemicals or abrasive tools
✘ Step directly on panels
✘ Ignore sudden performance drops
✘ Attempt electrical repairs without certification
✘ Delay maintenance if you notice signs of trouble

14. Warranty Considerations

Solar panels typically come with:

• Product warranty: 10–12 years

• Performance warranty: 25–30 years

• Installer workmanship warranty: 1–10 years (depending on contractor)

Tip: Document all maintenance, inspections, and issues to preserve warranty coverage and avoid future disputes.
