Note: Costs may vary based on specific factors such as installation requirements and panel quality. We can guide you in choosing the right system for your needs and budget.
Installation Costs for Solar Panels in Singapore
Installation costs are a significant part of the total investment and may include:
- Labor Charges: Depending on the complexity and duration of the installation.
- Permits and Inspections: Approvals from local authorities.
- Inverters and Mounting Systems: Convert solar energy into usable electricity and securely install panels.
At Sunollo, we simplify the process by managing installation from start to finish.
Solar Panel Maintenance Costs in Singapore
Maintaining your solar panels ensures optimal efficiency and longevity.
- Cleaning Services: Professional cleaning costs between $500 and $1,000 annually.
- Repairs or Replacements: Inverters, typically replaced every 10-15 years, may cost $2,500-$3,500.
We offer maintenance packages to ensure your system runs efficiently.
While solar panels require minimal upkeep, periodic maintenance ensures they continue to operate at peak efficiency. Below are key aspects of solar panel maintenance in Singapore:
a) Routine Cleaning
- Singapore’s occasional heavy rain helps clean solar panels naturally, but dust, bird droppings, and pollution can still accumulate.
- Panels should be cleaned every 3-6 months using a soft cloth, mild detergent, and water.
- Avoid abrasive materials that could scratch the panel surface.
b) Annual Inspections
- Professional solar providers offer annual maintenance checks to ensure system efficiency.
- Inspections typically include checking wiring, inverters, mounting structures, and overall system performance.
c) Monitoring System Performance
- Many solar providers offer real-time monitoring systems that track power generation and detect any inefficiencies.
- If you notice a drop in power output, it may indicate panel degradation, inverter issues, or shading problems.
d) Inverter Maintenance
- Since inverters have a shorter lifespan than panels, they should be inspected regularly for fault codes or error messages.
- Inverters are often installed in shaded or ventilated areas to prevent overheating.
e) Professional Maintenance Services
- Many solar panel providers in Singapore offer maintenance contracts to handle periodic servicing, repairs, and warranty claims.
- Services may include electrical testing, panel alignment, and inverter optimization to ensure maximum efficiency.
Solar Panel Warranties in Singapore
Solar panel warranties generally cover two main aspects:
a) Product Warranty (Manufacturer's Warranty)
- This warranty covers defects in materials and workmanship of the solar panels.
- Typically lasts 10 to 15 years, depending on the manufacturer.
- Ensures that the panels are free from manufacturing defects that could affect performance.
b) Performance Warranty
- Guarantees a specific power output over time, ensuring that the panels degrade at an acceptable rate.
- Most solar panel manufacturers offer a 25-year performance warranty, guaranteeing around 80-85% efficiency at the end of the term.
- For high-quality panels, the degradation rate is around 0.5% per year, meaning the panels should still generate significant power even after two decades.
c) Inverter Warranty
- The inverter is a crucial component that converts solar energy into usable electricity.
- Typically comes with a 5 to 10-year warranty, though premium brands may offer extended coverage up to 15 years.
d) Installation & Workmanship Warranty
- Covers installation-related issues such as loose wiring, faulty connections, or poor mounting.
- Usually ranges from 1 to 5 years, depending on the solar provider.
- Some reputable solar companies in Singapore offer extended installation warranties for added peace of mind.
e) Battery Storage Warranty (If Applicable)
- If you install a solar battery storage system, the warranty typically lasts 5 to 15 years.
- Covers capacity degradation, ensuring that the battery retains a certain percentage of its storage capability over time.
Benefits of Investing in Solar Panels in Singapore
