Cairns Solar Panel Maintenance

Essential Tips from Hielscher Electrical Expert

As the owner of Hielscher Electrical and a solar energy expert servicing Cairns and Far North Queensland, I understand the importance of solar panel maintenance for the local residential and commercial market. In this comprehensive guide, I’ll share my expertise on maintaining solar panels, ensuring homeowners in Cairns get the most out of their solar energy systems.

The increasing popularity of solar power in Australia, especially in sunny Queensland, means more people have solar panels installed on their roofs. However, not everyone is aware of the necessary maintenance to keep these panels in optimal condition. Just like cars or household appliances, solar panels require regular servicing and maintenance. In this guide, I’ll help you determine when to have your panels inspected, who can perform the job, potential costs, and the risks of neglecting solar maintenance.

Why is Solar Panel Maintenance Essential?

Solar panels, like any system, need maintenance throughout their lifespan. Regular upkeep helps maintain their efficiency, allowing them to generate energy at full capacity. Over time, elements like dust, leaves, animal droppings, and debris can accumulate on the panels, reducing their effectiveness. Water infiltration into the internal system can also cause significant issues. As a solar installer in Cairns, I recommend monitoring your panels regularly and being aware of potential problems.

Maintaining solar panels correctly ensures that you’re getting the most out of your solar panel system. Otherwise, you may be missing out on valuable energy production and potential energy bill savings. Neglecting maintenance can also lead to decreased performance or even solar panel fires. Although fires are rare with proper installation, having a professional inspect your panels can minimize this risk.

What Does Cairns Solar Panel Maintenance Entail?

During a solar panel service, a professional will ensure everything is functioning correctly. They will inspect the panels for cleanliness, security, and defects, and check for any deterioration or corrosion since installation. Electrical checks will be conducted to ensure all components and emergency procedures are operating properly, and the system will be examined for water infiltration.

The technician will generally clear major debris during the maintenance check. However, a more thorough cleaning may incur an additional fee. If any issues arise, such as faulty inverters or poor installation, they can be identified and fixed during the service.

For angled panels, cleaning isn’t typically necessary unless you live in a particularly dry or polluted area, or if animals or tall vegetation cause problems. Rain often suffices to keep solar panels clean, but if you have concerns, consider professional cleaning or do it yourself with appropriate precautions and equipment. Remember to turn off your system first and follow the manufacturer’s guidelines.

How Often Should Solar Panels Be Maintained?

Solar panels should be serviced approximately every five years, but always consult your manufacturer’s recommendations. If you notice any changes in performance or other concerns, have a professional inspect the system.

Watch for these warning signs that may warrant a one-off inspection:

  • A significant change in the system’s production
  • An alert from the monitoring software or solar inverter
  • A large build-up of debris
  • Suspected animal damage to the system (e.g., possums or birds)

What Are the Risks of Inadequate Solar Panel Maintenance?

Neglecting solar maintenance can lead to various issues, including:

  • Decreased performance: Accumulation of dirt and debris can reduce the efficiency of solar panels, leading to lower energy production and higher electricity bills.
  • Solar panel fires: Although rare, fires can occur due to issues like faulty wiring or poor installation. Regular maintenance can help identify and address such problems before they escalate.
  • Reduced lifespan: Proper maintenance ensures the longevity of your solar panel system. Neglecting upkeep can shorten its life

What is the cost of a solar panel service? A standard solar panel service generally costs $150-400, depending on the system size. Additional costs may apply for repairs. With a 25-30 year lifespan and services every five years, solar maintenance could cost around $2,000 over the lifetime of your system.

Who should service my solar panels? A professional, such as a licensed electrician or a Clean Energy Council-accredited solar panel system installer, should perform the service. This could be the company that installed your system or an independent business. Obtain quotes from several reputable businesses before booking a service.

Is solar panel servicing necessary?

Absolutely. If you’ve had your solar panels for over five years or notice any issues, have a professional inspect the system. This ensures maximum value for your money.
